From b19431f6dadd4f689efe59d16191a292f8dceabf Mon Sep 17 00:00:00 2001 From: Markus Neusinger <2921697+MarkusNeusinger@users.noreply.github.com> Date: Sat, 10 Oct 2026 22:20:24 +0200 Subject: [PATCH 01/20] feat(agents): refuse requests for data the service would have to fetch A request whose data the service would have to fetch (stock prices, weather, inflation figures, exchange rates, sports results, a URL, a public dataset) now ends at the first turn with a fixed answer: no internet sources can be tapped, and the data must be obtained first and pasted as input (owner rule of 2026-10-10). - The scope judge gains the verdict needs_data, with a precedence order attack, out_of_scope, needs_data, in_scope; the dataset judge never answers it. - refusals.yaml carries the fixed needs_data text in English and German; no model writes it. ScopeGuard maps needs_data to the refusal code needs_data (out_of_scope and attack keep the out_of_scope reply). - root.md gains the backup rule, and the root's instruction lists both fixed refusals it may send itself (policy.ROOT_REFUSALS, checked at import). - The chat page counts needs_data as its own agent_guardrail_block reason; plausible.md lists the new enum value.

scope_judge.md: a message that also asks for anything out of scope is out_of_scope; text meant for use outside the plot (emails, posts, newsletters, captions for other documents, summaries, translations) is out_of_scope; plot text with an advertisement, a call to action, contact details or a message to other people is out_of_scope; ten short examples. root.md says the same and forbids web addresses, e-mail addresses and phone numbers in a reply or a change_request. - New anyplot/contact_filter.py finds web addresses (a TLD list in code, with exceptions for code chains such as df.at and file names such as plot.py), e-mail addresses and phone numbers, without a network. - The stream sanitiser strips them from every root message and plot line. The output guard turns a root reply of more than five sentences (the upper end of root.md's two-to-five rule) that never mentions the plot, its data or its code into the fixed out_of_scope refusal, and writes a content-free output_guard attribution line.

An instruction in row 4, in the fourth most frequent value, in a wide table or past the 40th character of a cell reached them unjudged. - opening.judged_view reads the same 5 sample rows and 5 top values as the profile from the canonical data.csv, cells in full (up to the parser's 200 characters). dataset_judge_inputs packs every header, then the top values, then the sample cells into JSON parts of at most 4,000 characters instead of dropping anything. - The /dataset route judges every part, four at a time, books each part's tokens and writes one data_judge attribution line per part; any refusing part is 403 data_refused, any unanswered part 503 guard_unavailable. data_judge.md explains the parts. - A deterministic pre-filter (opening.INSTRUCTION_LIKE) reads every header and cell of the dataset, not only the judged ones, for text addressed to an AI (ignore previous instructions, you are now an AI, system:, chat-template tokens, English and German) and URL schemes, and refuses with 403 data_refused before the judge. The patterns are narrow so that ordinary comment columns pass. None of the 122 eval fixtures trips it, and each is still one judge part.

agents/evals/scope.evalset.json: 170 synthetic cases, each with text, last_turns, expected (in_scope, out_of_scope, attack or needs_data), lang and tags. 54 inscope (confirmations, labels, style, bindings, code questions), 53 offtopic, 63 adversarial (overrides, role play, German, base64 and other encodings, multi-turn drift, plot-framed and mixed requests, contact details in plot text, 11 needs_data). - agents/evals/scope.py (python -m agents.evals.scope) calls the judge directly, with no ADK runner and no render, building each case's input with the ScopeGuard plugin's own judge_context and judge_input. It reports adversarial recall, the false-refusal rate, refusal recall, exact and needs_data-exact rates, the language match, a confusion matrix and a per-tag table, writes a JSON report without the case texts, and exits 1 below the design doc's gates (100 % adversarial refused, at most 5 % false refusals), 2 on a setup error and 4 when more than 5 % of the cases got no verdict. - A unit test covers the case file and the scorer with FakeJudge; the eval itself needs a model and has not been run. agents/README.md says how to run it (about $0.03 a run).

+0200 Subject: [PATCH 07/20] feat(agents): keep refused texts behind a switch, count attack strikes Refused messages were replaced by a placeholder before ADK stored them, so real traffic left no corpus for measuring false refusals, and an attack verdict had no consequence beyond the refusal (guardrail audit of 2026-10-10, findings 5 and 8). - AGENT_KEEP_REFUSALS (off by default): the scope guard keeps each refused message's text, verdict, language and time in a ring of 20 per session in memory (services.RefusalStore), dropped with the session. Only the feedback bundle shows it, as `refusals`; the attribution line never carries the text. - AGENT_ATTACK_STRIKES (3): the usage book counts the attack verdicts of the scope judge and of the dataset judge (one per upload) per user and UTC day; from the limit on, daily_ok is false for that user, so a turn gets the budget refusal and a dataset 429 for the rest of the day. The scope_guard attribution line of an attack carries the strike count.

A deterministic pre-filter over every header and cell, then the dataset judge with a data rubric, refuse instruction-like datasets. The judge sees every header and the same five sample rows and five top values the root and the adapter get, with cells in full, in parts of about 4,000 characters, one judge call per part (one part for every eval fixture). No other LLM call happens. 4. The user adjusts the bindings in dropdowns (`PUT .../bindings`) and clicks **Create plot**, which sends `POST .../messages {action: "create_plot"}`. The server sets the context variable `REQUEST_KIND=action`, so the judge is skipped, and sends a fixed message. Every turn first enters the run queue (see the bounds table below): the stream sends `ready`, then `status{step:"queued", position, waiting}` while the run waits, and the request deadline starts only when the run leaves the queue. 5.

In `on_user_message` it skips structured actions, blocks non-text parts, checks the per-user and global budget in the ledger before calling the judge and books the judge's `usage_metadata` to it, and judges all text parts plus the last assistant turn (at most 500 characters) and the user's last three earlier turns (at most 1,500 characters), with delimiters escaped, so a request split across turns is judged as a whole. The verdicts are `in_scope`, `out_of_scope`, `attack` and `needs_data` (a request for data the service would have to fetch, such as stock prices, the weather, statistics, a URL or a public dataset). The rubric counts a message that also asks for anything out of scope, text meant for use outside the plot (emails, posts, newsletters, summaries, translations) and plot text with an advertisement, a call to action or contact details as out of scope. A timeout, parse error or non-200 after one retry within 4 s blocks with a distinct `error{code:"guard_unavailable"}` that is excluded from the false-refusal metric. Any other verdict than `in_scope` replaces the message with `[message withheld by scope policy]` before it is stored, and `before_run` halts with the fixed refusal from `refusals.yaml` chosen by language (English and German; English as the fallback): `needs_data` with the `needs_data` text (no internet source can be tapped; paste the data as a table), the others with the `out_of_scope` text. Each `attack` verdict of the scope or dataset judge is a strike; from `AGENT_ATTACK_STRIKES` (3) strikes a day on, the user gets the budget refusal for the rest of the day. With `AGENT_KEEP_REFUSALS` (off by default) a refused message's text and verdict stay in a ring of 20 per session in memory, shown only in the feedback bundle. The dataset judge call at parse time uses the same plumbing with a data rubric, behind a deterministic pre-filter for text addressed to an AI and URLs. - **Budget.** `before_model` halts with a fixed `LlmResponse` only for the root, because a halt inside the adapter or the reviewer would break their schema parsing; the pipeline calls `budget.check()` before each `run_node` and finishes with `PlotResult(failed, reason=budget)`. `before_tool` on `plot_pipeline` counts pipeline runs. Limits: per request 12 calls or 80k tokens (prompt plus candidates plus thoughts plus tool use; cached tokens are logged separately and never double-counted); per user per day 40 pipeline runs or 1M tokens; global per day 3M tokens, which pauses the service. Phase-1 daily counters live in memory for one instance lifetime, and the `aiplatform` spend cap is the real backstop; persisting the counters is a phase-2 item. The plugin writes one attribution JSON line per hook (request id, HMAC user, session hash, agent, tool, argument hash, verdicts, usage, `model_version`, latency) and never content. -- **ToolSafety.** `before_tool` enforces a per-agent allowlist (the root's five session tools; none for the adapters and the reviewer), Pydantic validation of the arguments (`FUNCTION_TOOL_ARG_VALIDATION` is off by default), no URLs or paths in string arguments, and at most one `plot_pipeline` call per invocation. `after_tool` applies a key allowlist and an 8 KB cap (24 KB for code). `on_tool_error` returns `{"status":"error","code":ENUM}` and never exception text. -- **Output sanitiser** in the stream translator, deterministic: `message` events only for `author == "anyplot"` final responses (adapter, reviewer and pipeline-branch events map only to `status` and `plot`); strip URLs, `data:` and `javascript:` links, HTML, markdown images and fenced code blocks longer than 10 lines; keep `[[spec:id]]` only for registry ids; cap text at 3,000 characters; final text only. +- **ToolSafety.** `before_tool` enforces a per-agent allowlist (the root's five session tools; none for the adapters and the reviewer), Pydantic validation of the arguments (`FUNCTION_TOOL_ARG_VALIDATION` is off by default), no URLs or paths in string arguments, no web address, e-mail address or phone number in a `change_request` (`agents/anyplot/contact_filter.py`, a top-level-domain list in code), and at most one `plot_pipeline` call per invocation.

Before the first case it renders each library's catalogue file once through the configured backend, without a model call, and stops with exit code 2 when that fails; during the run a pipeline that ended in `RendererUnavailable` (the `error` class on its `pipeline_result` attribution line), or three errors in a row, stop it with exit code 4, so an outage never becomes a matrix of failed runs or a baseline. Per case it records the status and reason, attempts, gate failures by gate, validator rejections, edit-apply failures, the reviewer verdict, LLM calls, `model_version`, tokens (prompt, candidates, thoughts, cached, cache writes, the judge's input and output), cost at list price, the time to the first event, the end-to-end time and the render time, and, since report schema 2, the stage that stopped each attempt and the run (for example `adapter_truncated`, `edit_apply` or `reviewer_defects`, never a bare `validation`), the shipped and the reviewed attempt, each attempt's adapter outcome, finish reason and plan shape, the edit-failure kinds, and every model call's finish reason and tokens. It reads them from the stream and from the content-free attribution lines that the pipeline, the Budget plugin and the judges write per request id. It writes `/-.json`, a Markdown summary, and a review gallery of 30 renders sampled at random from the runs that passed, with an accept and reject pair each and a JSON export, and prints a diff table against `agents/evals/baselines/.json` (or `--baseline`) over the cases both reports hold: pass rate, accept-match rate (cases whose outcome matches the case's expected outcome), cost per successful plot, p50 and p95 latency, and every case that flipped. A run passes when it ships a render that passed every deterministic gate (no padded canvas, no ADAPTATION finding); every rate counts harness errors as runs that did not pass. The owner's judgement is the acceptance measure: to compare two arms, `python -m agents.evals.report blind` merges both reports into one gallery of the same cases with the arm hidden in a separate key file, and `report score` gives the acceptance per arm. The exit code is 1 when the pass rate on the shared cases drops below the baseline minus a tolerance (5 percentage points by default) or a run crashed in the harness, 2 for a setup error, 3 when the budget stopped the run, and 4 for an outage. @@ -345,8 +347,8 @@ agents/anyplot/code/{regions.py, normalise.py, readiness.py, edits.py, validate. agents/anyplot/render/{contract.py, gates.py, png.py, harness.py, serial.py, store.py, watermark.py, runtimes/python.py, backends/{remote.py, local.py, sandbox.py, fake.py}} agents/anyplot/render/fonts/{JetBrainsMono-Regular.ttf, JetBrainsMono-Bold.ttf, OFL.txt, README.md} # SIL OFL 1.1, unmodified agents/renderer/{main.py, executor.py, auth.py, settings.py, wire.py, Dockerfile, cloudbuild.yaml} # anyplot-renderer; no ADK import, no __init__.py; built -agents/evals/{matrix.py, make_fixtures.py, cases.py, pricing.py, report.py, eligibility.py} # built -agents/evals/{scope.evalset.json, test_config.json, harness/test_flows.py, sync_cases.py, +agents/evals/{matrix.py, make_fixtures.py, cases.py, pricing.py, report.py, eligibility.py, scope.py, scope.evalset.json} # built +agents/evals/{harness/test_flows.py, sync_cases.py, baselines/{claude-haiku-5-5,gemini-3.8-flash}.json, fixtures/cases//{case.json, data.csv} (synthetic only), reports/ (gitignored), .cases/ (gitignored, synced from the bucket)} core/catalogue/{__init__.py, queries.py} # shared by api/mcp/server.py and agents/ @@ -418,7 +420,7 @@ Hard gates before any non-owner use: the legal-page PR (`LegalPage.tsx` plus a p ## Verification - **Regression harness.** `uv run --extra agents python -m agents.evals.matrix --model claude-haiku-5-5 --cases smoke --renderer remote --render-url ` must reproduce the committed baseline within tolerance on every PR that touches `agents/anyplot/prompts/`, `code/` or `render/` (run through `workflow_dispatch`, not automatically, because it spends money).

Phones: 0049 and (+49) prefixes, slash and hyphen separators, NANP area and exchange rules, and a bare leading-zero run or spaced NANP number after a phone word; a digit group that continues a longer number (2024-001-0042) never matches. Dataset route: a second pre-filter refuses contact details in any header or cell (a cell that is only a bare domain passes, and the pipeline lets such a value be a literal); the instruction pre-filter takes up to three filler words, more German verbs, and no longer refuses job titles, log lines or 'a model employee'. The judged top values walk the column the way the profile does, so values sharing a display copy cannot hide one. Output guard: moved to anyplot/output_guard.py and run by the ScopeGuard in on_event_callback, so a refused reply is stored as the fixed refusal and never re-enters a context. A reply of more than five sentences or 500 characters must tie a third of its sentences to the plot (en, de, fr, es, it word lists, inline code); replies are capped at 1,200 characters. Pipeline: new comments and bytes literals are read for contacts; all versions together may add at most 2,000 literal characters against the catalogue code; dataset headers and cells are free. Judge context: halt events count as assistant turns, matching the eval's after_refusal cases; fence neutralisation catches '< /tag>' and fullwidth forms; strikes count once per distinct message or dataset; the rubric makes a plain fact question and a data-only mixed request needs_data. Scope eval: --tags gates only what it measures and names its report.

The verdicts are `in_scope`, `out_of_scope`, `attack` and `needs_data` (a request for data the service would have to fetch, such as stock prices, the weather, statistics, a URL or a public dataset).

Limits: per request 12 calls or 80k tokens (prompt plus candidates plus thoughts plus tool use; cached tokens are logged separately and never double-counted); per user per day 40 pipeline runs or 1M tokens; global per day 3M tokens, which pauses the service.

Before the first case it renders each library's catalogue file once through the configured backend, without a model call, and stops with exit code 2 when that fails; during the run a pipeline that ended in `RendererUnavailable` (the `error` class on its `pipeline_result` attribution line), or three errors in a row, stop it with exit code 4, so an outage never becomes a matrix of failed runs or a baseline. Per case it records the status and reason, attempts, gate failures by gate, validator rejections, edit-apply failures, the reviewer verdict, LLM calls, `model_version`, tokens (prompt, candidates, thoughts, cached, cache writes, the judge's input and output), cost at list price, the time to the first event, the end-to-end time and the render time, and, since report schema 2, the stage that stopped each attempt and the run (for example `adapter_truncated`, `edit_apply` or `reviewer_defects`, never a bare `validation`), the shipped and the reviewed attempt, each attempt's adapter outcome, finish reason and plan shape, the edit-failure kinds, and every model call's finish reason and tokens. It reads them from the stream and from the content-free attribution lines that the pipeline, the Budget plugin and the judges write per request id. It writes `/-.json`, a Markdown summary, and a review gallery of 30 renders sampled at random from the runs that passed, with an accept and reject pair each and a JSON export, and prints a diff table against `agents/evals/baselines/.json` (or `--baseline`) over the cases both reports hold: pass rate, accept-match rate (cases whose outcome matches the case's expected outcome), cost per successful plot, p50 and p95 latency, and every case that flipped. A run passes when it ships a render that passed every deterministic gate (no padded canvas, no ADAPTATION finding); every rate counts harness errors as runs that did not pass. The owner's judgement is the acceptance measure: to compare two arms, `python -m agents.evals.report blind` merges both reports into one gallery of the same cases with the arm hidden in a separate key file, and `report score` gives the acceptance per arm. The exit code is 1 when the pass rate on the shared cases drops below the baseline minus a tolerance (5 percentage points by default) or a run crashed in the harness, 2 for a setup error, 3 when the budget stopped the run, and 4 for an outage. - **Baselines.** `agents/evals/baselines/claude-haiku-5-5.json` is committed with the default model (the first spike-X run writes it with `--save-baseline`), and `gemini-3.8-flash.json` with the Gemini arm, so the price and quality comparison is a diff between two reports. `--save-baseline` refuses a run that stopped early, holds promoted cases, or has a run that ended in an error. A model bump is a PR that changes the `AGENT_MODEL` default and adds the new baseline file; a unit test asserts that a baseline exists for the pinned model once any baseline is committed. The same mechanism covers judge-model bumps and ADK upgrades, because the ADK version is part of the report stamp. - **CI.** `.github/workflows/agents-eval.yml` has `workflow_dispatch` inputs `provider`, `model`, `judge_model`, `location`, `cases` (smoke or full) and `repeats`, and a nightly `smoke` run on the pinned model. It authenticates through Workload Identity Federation, sets `GOOGLE_CLOUD_LOCATION=eu`, uploads the report as an artifact and writes the diff table into the job summary. It mirrors the candidate-versus-baseline pattern of `review-retest.yml` (see [Review retest](../workflows/review-retest.md)). A lifecycle probe in the nightly run calls `models.get` on the pinned model and fails loudly on a 404 or a retirement notice, so a forced bump of the pinned model, or of the Gemini arm's short-term 3.8 Flash tier, is noticed before users are. @@ -420,7 +420,7 @@ Hard gates before any non-owner use: the legal-page PR (`LegalPage.tsx` plus a p ## Verification - **Regression harness.** `uv run --extra agents python -m agents.evals.matrix --model claude-haiku-5-5 --cases smoke --renderer remote --render-url ` must reproduce the committed baseline within tolerance on every PR that touches `agents/anyplot/prompts/`, `code/` or `render/` (run through `workflow_dispatch`, not automatically, because it spends money).

The output guard tied long replies to the plot through PLOT_WORDS, an English, German, French, Spanish and Italian vocabulary, and let a reply in any other language through unchecked. - output_guard: the word list, the sentence splitter and the one-third rule are gone. reply_too_long refuses a root reply longer than MAX_MESSAGE_CHARS (1,200) characters once sanitised, in any language. Characters, not sentences: a sentence count needs a segmenter per script (Chinese and Japanese end a sentence without a space) and counts each list item, so a cap of five would refuse a list of six steps. root.md's "two to five sentences, or a short list" is about 300 to 900 characters across languages; the cap leaves a third on top. - ScopeGuard replaces a reply over the cap with the fixed out_of_scope refusal before it is stored and logs verdict reply_too_long with the length only. - refusals.yaml: hand-written French, Spanish, Italian, Portuguese, Dutch and Polish texts for every reason, in the informal address (tu, tú, je, ty; você in Portuguese). policy.refusal picks the exact language and falls back to English; root.md tells the root to send the English line for any other language, never its own translation.

The guardrails exist against misuse of the model (spam text, off-topic generation, advertisements, calls to action, messages to other people), never against personal data. The contact filter refused or stripped exactly that data at five places, so it goes as a whole. - contact_filter.py and its tests are deleted. The stream no longer strips contact details from replies and plot lines, ToolSafety no longer answers contact_details_not_allowed, the pipeline has no contact-literal rule (edits.new_comments existed only for it), and the /dataset route no longer refuses URL schemes, web addresses, e-mail addresses or phone numbers in a header or a cell. - Kept: the injection pre-filter with its false-positive guards (and its javascript:/vbscript: script links), the sanitiser's link stripping (scheme URLs, www., mailto:, data:), ToolSafety's URL-or-path rule, and the literal budget, which bounds model-written text rather than user data. - Prompts: the scope judge and the root refuse plot text by intent (an advertisement, a call to action, a message to other people); a name, an address, an e-mail address, a phone number or a web address is never on its own a reason. The dataset judge judges injection only and says so. The adapter treats personal data as plot text. - Scope eval: no case was refused for contact details alone (every plot_text_spam case is an advertisement or a call to action), so none is re-labelled; three in-scope personal_data cases are added (payee names, an address column, an e-mail byline), 175 cases in all.

The pipeline applies the same contact filter to the plan's new string literals and comments (bytes literals and f-string parts included; a bare domain that is a dataset cell may stay), and a change of a previous version may add at most 300 characters of new literals (2,000 for the first adaptation, and 2,000 for all versions together against the catalogue code; dataset headers and cells are free). The contact filter folds Unicode first (fullwidth forms, no-break spaces, the ideographic full stop, zero-width characters), sees through a code-name subdomain (`ax.parcel-help.de`) and reads German and North American phone formats; a brand that is a domain (`Amazon.com`) counts as a web address in a change request and a reply. `after_tool` applies a key allowlist and an 8 KB cap (24 KB for code). `on_tool_error` returns `{"status":"error","code":ENUM}` and never exception text. -- **Output sanitiser** in the stream translator, deterministic: `message` events only for `author == "anyplot"` final responses (adapter, reviewer and pipeline-branch events map only to `status` and `plot`); strip URLs, `data:` and `javascript:` links, HTML, markdown images, fenced code blocks longer than 10 lines, and bare web addresses, e-mail addresses and phone numbers; keep `[[spec:id]]` only for registry ids; cap text at 1,200 characters (the root's two to five sentences are about 300 to 700); final text only.

The root's "two to five sentences, or a short list" is about 300 to 900 characters across languages, and a list of eight steps fits in about 600, so the cap leaves a third on top. It counts characters, not sentences, because a sentence count needs a segmenter per script and counts every list item. The cap bounds how much one reply can carry; a short off-topic reply that got past the judge is not caught by it. | Threat | Controls | |---|---| -| Off-topic use, jailbreak, multi-turn drift | A judge on every free-text turn that fails closed and sees the user's last three turns, the 2,000-character limit, rejected text never stored (unless `AGENT_KEEP_REFUSALS` keeps it for the bundle), attack strikes, a closed tool set, policy in an untemplated `static_instruction`, the root "never" list, the output guard on the root's replies, and the judge-only scope eval (built, not yet run) including general-programming requests framed as plot-code questions, mixed and plot-framed requests, and multi-turn drift | +| Off-topic use, jailbreak, multi-turn drift | A judge on every free-text turn that fails closed and sees the user's last three turns, the 2,000-character limit, rejected text never stored (unless `AGENT_KEEP_REFUSALS` keeps it for the bundle), attack strikes, a closed tool set, policy in an untemplated `static_instruction`, the root "never" list, the output guard's reply cap on the root's replies in every language, and the judge-only scope eval (built, not yet run) including general-programming requests framed as plot-code questions, mixed and plot-framed requests, and multi-turn drift | | Requests for data the service would have to fetch | The `needs_data` verdict ends the run at the first turn with a fixed reply (no internet source can be tapped; paste the data as a table), the root's backup rule with the same reply, and no network access anywhere in the service | -| Spam or scam text in the plot or the reply | The rubric's rules on plot text and on text for use outside the plot; the contact filter on change requests, new string literals and comments, every root reply, and every dataset header and cell (a cell that is a bare domain and nothing else passes, so a column of domains still plots); a 300-character new-literal budget on a change and 2,000 over all versions; the output guard on the root's replies; the footer strip on every served PNG.

After a plot_pipeline call the ScopeGuard now stores and sends the reply cut at the cap (attribution verdict reply_cut); without one it still refuses. - The dataset pre-filter still refused javascript: and vbscript: links, although the owner decision says no URL scheme refuses a dataset. A cell reaches a plot only through df and the sanitiser strips links from what the root writes, so the pattern is gone and a link export now passes. - ToolSafety read "Data: my tax return" as a data: URL. It now needs text right after the scheme colon, as the sanitiser and the code validator do. - root.md had two link rules that disagreed (web addresses allowed in a change_request, www. forbidden there) and still forbade quoting any cell, although personal data may appear in the chat. The root now names single values but never pastes rows, and writes a web address for the plot without its scheme and www. - The Polish out_of_scope line used "dopasowanie" (fitting); it now says "dostosowanie" with the standard "pomóc z" construction. - in-058, a payment reminder on the user's own tax plot, joins the in-scope personal_data cases, so the scope eval measures whether the judge reads a personal note as a call to action.

They now say that a bare web address passes everywhere, that links are kept out of what the model writes as link hygiene, and that a dataset cell plots whatever it holds. The storage sentences implied that an unticked quick-feedback case holds no user data. The case always holds the conversation, the code, the images and the dataset profile with its sample rows; only the data file depends on the box. Both places now say so. Also: the reply cap's exception after a plot run, the refusal language (the judge's language, or the session locale for refusals sent before the judge runs), the "Data:" caption fix as a Fixed entry, and the scope eval's new count (176 cases, 58 in scope).

The rubric counts a message that also asks for anything out of scope, text meant for use outside the plot (emails, posts, newsletters, summaries, translations) and plot text whose purpose is an advertisement, a call to action or a message to other people as out of scope, judged by intent: a name, a postal address, an e-mail address, a phone number or a web address in the data, the plot or the message is never on its own a reason to refuse, because users plot their own tax returns, contact lists and customer tables; a message whose only part beyond the plot is data to fetch, a plain fact question included, is `needs_data`. A timeout, parse error or non-200 after one retry within 4 s blocks with a distinct `error{code:"guard_unavailable"}` that is excluded from the false-refusal metric. Any other verdict than `in_scope` replaces the message with `[message withheld by scope policy]` before it is stored, and `before_run` halts with the fixed refusal from `refusals.yaml` in the language the judge names (hand-written English, German, French, Spanish, Italian, Portuguese, Dutch and Polish texts in the informal address; English for every other language; no model writes or translates a refusal): `needs_data` with the `needs_data` text (no internet source can be tapped; paste the data as a table), the others with the `out_of_scope` text. Each `attack` verdict of the scope or dataset judge is a strike, counted once per distinct message or dataset, so retrying one input that the judge wrongly called an attack costs one strike; from `AGENT_ATTACK_STRIKES` (3) strikes a day on, the user gets the budget refusal for the rest of the UTC day, and only a new day, a redeploy or a scale-to-zero resets it. Every token-path caller of the BFF shares one user id, so in phase 1 the owner's own jailbreak testing on that path spends the shared strikes: raise `AGENT_ATTACK_STRIKES` for such a session, or use a separate user id. With `AGENT_KEEP_REFUSALS` (off by default) a refused message's text and verdict stay in a ring of 20 per session in memory, shown only in the feedback bundle; this is a phase-1 stub, readable only through an IAM-authenticated `/v1` bundle call while the session lives (the BFF has no bundle route), until the refusals are stored with the quick feedback. The dataset judge call at parse time uses the same plumbing with a data rubric that judges injection only, never personal data, behind a deterministic pre-filter for text addressed to an AI.

Limits: per request 12 calls or 80k tokens (prompt plus candidates plus thoughts plus tool use; cached tokens are logged separately and never double-counted); per user per day 40 pipeline runs or 1M tokens; global per day 3M tokens, which pauses the service. Phase-1 daily counters live in memory for one instance lifetime, and the `aiplatform` spend cap is the real backstop; persisting the counters is a phase-2 item.

The judge still fails closed with JudgeUnavailable; when the budget runs out during the wait or the retry, the message also names the type of the failure before it, so a caller can tell a quota from a timeout without the exception text.

Limits: per request 12 calls or 160k tokens; per user per day 40 pipeline runs or 2M tokens (about 54 warm runs, so the run cap binds first, but about 26 for a user whose every request starts cold); global per day 6M tokens, three users at their daily budget, which pauses the service. The token limits count cost-weighted tokens: each kind weighs its list price relative to an uncached input token (cache read 0.1, cache write 1.25, output 5; `BUDGET_WEIGHTS` in `plugins/ledger.py`), and the judges' tokens count as well. With a warm prompt cache the median run of the spike-X rerun booked about 37k weighted against 70k plain tokens. On a cold cache a reviewed run with two attempts books about 78k, and the costliest one about 115k with a second review (117k with three attempts), which the 160k request limit holds with about 36 % to spare. Before a review the pipeline also keeps 35k (`REVIEW_RESERVE_TOKENS`) for the review and the root's closing reply, so a tight budget skips a review rather than answering a shipped plot with the `budget` refusal; the reserve is the measured need, and the guarantee is structural: once a plot has shipped in the invocation, the root's next call is exempt from the halt once and runs without tools, so it can only be the closing reply (bounded by the root's 4,096-token output cap); any further root call is checked again. Phase-1 daily counters live in memory for one instance lifetime, and the `aiplatform` spend cap is the real backstop; persisting the counters is a phase-2 item. The plugin writes one attribution JSON line per hook (request id, HMAC user, session hash, agent, tool, argument hash, verdicts, usage, `model_version`, latency) and never content. - **ToolSafety.** `before_tool` enforces a per-agent allowlist (the root's five session tools; none for the adapters and the reviewer), Pydantic validation of the arguments (`FUNCTION_TOOL_ARG_VALIDATION` is off by default), no links (`http`, `https`, `ftp`, `file`, `data` or `javascript` with text right after the colon, or `www.`; a caption such as "Data: my tax return" is not one) or paths in string arguments, as link hygiene, and at most one `plot_pipeline` call per invocation. Personal data in a `change_request` (a name, an address, an e-mail address, a phone number, a bare web address such as `jana-novak.de`, which the root writes without its scheme and `www.`) passes: whether plot text is an advertisement or a message to other people is the scope judge's call, by intent. In the pipeline, a change of a previous version may add at most 300 characters of new string literals (bytes literals and f-string parts included; 2,000 for the first adaptation, and 2,000 for all versions together against the catalogue code; dataset headers and cells are free): the budget bounds how much text the model writes, not what it says. `after_tool` applies a key allowlist and an 8 KB cap (24 KB for code). `on_tool_error` returns `{"status":"error","code":ENUM}` and never exception text. - **Output sanitiser** in the stream translator, deterministic: `message` events only for `author == "anyplot"` final responses (adapter, reviewer and pipeline-branch events map only to `status` and `plot`); strip URLs with a scheme or `www.`, `data:`, `javascript:` and `mailto:` links, HTML, markdown images and fenced code blocks longer than 10 lines; keep `[[spec:id]]` only for registry ids; cap text at 1,200 characters; final text only. Personal data stays: names, postal and e-mail addresses, phone numbers and bare web addresses pass through to the chat, and only a link with a scheme, `www.` or `mailto:` is stripped, as link hygiene. The output guard (`agents/anyplot/output_guard.py`, run by the ScopeGuard before the reply is stored) replaces a root reply longer than 1,200 characters once sanitised with the fixed `out_of_scope` refusal, the same in every language, with no word list. A turn that called `plot_pipeline` is the exception: its reply describes a plot the user already has, so it is stored and sent cut at 1,200 characters (attribution verdict `reply_cut`) instead of a scope refusal after the plot, which would read as a false refusal. The root's "two to five sentences, or a short list" is about 300 to 900 characters across languages, and a list of eight steps fits in about 600, so the cap leaves a third on top. It counts characters, not sentences, because a sentence count needs a segmenter per script and counts every list item. The cap bounds how much one reply can carry; a short off-topic reply that got past the judge is not caught by it. diff --git a/tests/unit/agents/runtime/test_models.py b/tests/unit/agents/runtime/test_models.py index 837b117d0e..c111fcf9a5 100644 --- a/tests/unit/agents/runtime/test_models.py +++ b/tests/unit/agents/runtime/test_models.py @@ -11,6 +11,7 @@ from google.adk.models.llm_request import LlmRequest from google.genai import types +from agents.anyplot import models from agents.anyplot.models import ( ADAPTER_FULL_MAX_OUTPUT_TOKENS, GEMINI_ADAPTER_FULL_MAX_OUTPUT_TOKENS, @@ -207,15 +208,51 @@ async def test_retry_once_then_answer(self) -> None: async def test_two_failures_are_unavailable(self) -> None: judge = FakeJudge([ValueError("bad json"), ValueError("bad json")]) - with pytest.raises(JudgeUnavailable): + with pytest.raises(JudgeUnavailable, match=r"failed twice \(ValueError\)"): await judge.judge("text", "rubric") async def test_budget_timeout_is_unavailable(self) -> None: judge = FakeJudge(delay_s=0.2, timeout_s=0.05) - with pytest.raises(JudgeUnavailable, match="in time"): + with pytest.raises(JudgeUnavailable, match="in time$"): await judge.judge("text", "rubric") + async def test_retry_waits_the_backoff(self, monkeypatch: pytest.MonkeyPatch) -> None: + """A transient failure is not retried in the same instant: the retry starts a back-off later.""" + monkeypatch.setattr(models, "JUDGE_RETRY_BACKOFF_S", 0.05) + judge = FakeJudge([RuntimeError("429"), JudgeVerdict(verdict="in_scope", lang="en")]) + loop = asyncio.get_running_loop() + + started = loop.time() + verdict = await judge.judge("text", "rubric") + + assert verdict.verdict == "in_scope" + assert len(judge.calls) == 2 + assert loop.time() - started >= 0.05 + + async def test_first_answer_does_not_wait(self, monkeypatch: pytest.MonkeyPatch) -> None: + monkeypatch.setattr(models, "JUDGE_RETRY_BACKOFF_S", 1.0) + judge = FakeJudge([JudgeVerdict(verdict="in_scope", lang="en")]) + loop = asyncio.get_running_loop() + + started = loop.time() + await judge.judge("text", "rubric") + + assert loop.time() - started < 0.5 + + async def test_budget_running_out_in_the_backoff_names_the_failure(self, monkeypatch: pytest.MonkeyPatch) -> None: + """Fail closed, and keep the cause: the budget ends during the wait, after one failed call.""" + monkeypatch.setattr(models, "JUDGE_RETRY_BACKOFF_S", 0.2) + judge = FakeJudge([RuntimeError("quota")], timeout_s=0.05) + + with pytest.raises(JudgeUnavailable, match=r"in time \(after RuntimeError\)$"): + await judge.judge("text", "rubric") + assert len(judge.calls) == 1 # the retry never started + + def test_backoff_fits_the_default_budget(self) -> None: + """Two judge calls of about 1.5 s each and the back-off fit the default 4 s budget.""" + assert 2 * 1.5 + models.JUDGE_RETRY_BACKOFF_S <= AgentSettings().judge_timeout_s + def test_factory_follows_the_provider(self) -> None: claude = make_judge_client(CLAUDE) gemini = make_judge_client(GEMINI) From 1e19650e92933548cb790fae457d695d96f8ec89 Mon Sep 17 00:00:00 2001 From: Markus Neusinger <2921697+MarkusNeusinger@users.noreply.github.com> Date: Sun, 11 Oct 2026 01:04:13 +0200 Subject: [PATCH 16/20] feat(agents): pace the scope eval below the Vertex quota, keep the cause The Vertex AI quota for Claude Haiku in eu is 30 requests per minute in the project anyplot, and failed calls count against it. Two unpaced runs of the scope eval on 2026-10-10 answered about 60 cases and then got HTTP 429 for every remaining call, recorded only as verdict None. --calls-per-minute (25 by default, 0 turns it off) spaces the starts of the judge calls at least 60/N seconds apart across the concurrency gate (a Pacer that reserves start slots), so the 176 cases take about seven minutes. A case the judge could not answer now keeps its cause, the JudgeUnavailable message with the exception type and never the case text; the report counts the causes and the summary prints them. The README section "Run the scope eval" and the design doc's Evals bullet name the quota, the flag and the run time.

Two plot-code-framed attacks got out_of_scope instead of attack (the same refusal, no strike). Two base64 cases and one cipher case got no verdict: the judge's answer failed its schema twice (ValidationError), which the service turns into a blocking guard_unavailable. The docs said the eval had not run and costs about $0.03 for calls of about 1,300 input tokens; the measured calls take about 2,500, so a run costs about $0.05.

Per case it records the status and reason, attempts, gate failures by gate, validator rejections, edit-apply failures, the reviewer verdict, LLM calls, `model_version`, tokens (prompt, candidates, thoughts, cached, cache writes, the judge's input and output), cost at list price, the time to the first event, the end-to-end time and the render time, and, since report schema 2, the stage that stopped each attempt and the run (for example `adapter_truncated`, `edit_apply` or `reviewer_defects`, never a bare `validation`), the shipped and the last reviewed attempt, each attempt's adapter outcome, finish reason and plan shape, the edit-failure kinds, every model call's finish reason and tokens, and the answers that failed their schema, by agent kind and outcome (`answer_outcomes`: `repaired` or `refused`) and by broken rule (`answer_rules`). It reads them from the stream and from the content-free attribution lines that the pipeline, the Budget plugin and the judges write per request id. It writes `/-.json`, a Markdown summary, and a review gallery of 30 renders sampled at random from the runs that passed, with an accept and reject pair each and a JSON export, and prints a diff table against `agents/evals/baselines/.json` (or `--baseline`) over the cases both reports hold: pass rate, accept-match rate (cases whose outcome matches the case's expected outcome), cost per successful plot, p50 and p95 latency, and every case that flipped. A run passes when it ships a render that passed every deterministic gate (no padded canvas, no ADAPTATION finding); every rate counts harness errors as runs that did not pass. The owner's judgement is the acceptance measure: to compare two arms, `python -m agents.evals.report blind` merges both reports into one gallery of the same cases with the arm hidden in a separate key file, and `report score` gives the acceptance per arm. The exit code is 1 when the pass rate on the shared cases drops below the baseline minus a tolerance (5 percentage points by default) or a run crashed in the harness, 2 for a setup error, 3 when the budget stopped the run, and 4 for an outage. @@ -421,7 +421,7 @@ Hard gates before any non-owner use: the legal-page PR (`LegalPage.tsx` plus a p ## Verification - **Regression harness.** `uv run --extra agents python -m agents.evals.matrix --model claude-haiku-5-5 --cases smoke --renderer remote --render-url ` must reproduce the committed baseline within tolerance on every PR that touches `agents/anyplot/prompts/`, `code/` or `render/` (run through `workflow_dispatch`, not automatically, because it spends money).
