From 05b41f6f72c73fe907261f5fce7bad5dc087b2ee Mon Sep 17 00:00:00 2001 From: Aldrin Joseph Date: Thu, 29 Oct 2026 00:24:58 +0530 Subject: [PATCH] feat(integrations): add OKF v0.2 bundle toolset Expose a directory of typed markdown knowledge (Open Knowledge Format v0.2) to an agent progressively: frontmatter index (L1), one concept body (L2), its attached resources (L3), and a deterministic offline search. Trust tier, lifecycle, and staleness are derived from frontmatter on every read and used only to filter discovery. A bundle is untrusted input. Concept bodies and resource text are labelled as data, never instructions; every path argument resolves through one bundle-root guard that refuses `..` traversal and symlink escape at load time as well as at call time; and no tool raises, so a hostile or broken bundle reaches the model as a structured error dict instead of an opaque failure. 107 tests, including an adversarial suite and golden tests over the four published OKF sample bundles. --- docs/guides/README.md | 1 + docs/guides/integrations/okf/toolset/index.md | 119 +++++ src/google/adk/integrations/okf/README.md | 45 ++

YAML frontmatter says what each one is, whether a human or a machine verified it, and when it goes stale. The tools disclose the corpus progressively — an index of frontmatter rows first, one concept's body second, its attached resources third — so the context bill is paid per concept the model actually reads. + +## Introduction + +ADK already has a strong story for procedural knowledge: a `SKILL.md` tree tells the agent *how* to do something. What an agent grounded in a versioned knowledge corpus needs is the other half — a way to consume what the corpus *says*, without either loading all of it into the system prompt or building a bespoke retrieval layer beside it. + +That corpus usually already has a shape. The [Open Knowledge Format (OKF) v0.2](https://github.com/GoogleCloudPlatform/open-knowledge-format) describes it: every concept is a markdown file with YAML frontmatter carrying `type`, `description`, `tags`, `sources`, `generated`, `verified`, `status`, and `stale_after`. The structure is the index, and `OkfToolset` reads it as one. + +Three properties of the format do the work here: + +- **`type` and `tags` are authored metadata**, so filtering happens before any body is read. +- **`verified` carries actors** (`human:`, `/`), so trust is derived per concept rather than assumed per corpus. +- **`status` and `stale_after` are dated**, so a deprecated or expired concept can be reported as such instead of silently cited as current. + +`OkfToolset` is a `BaseToolset`. Bind it to a bundle directory and it returns four `FunctionTool` instances. Parsing, trust derivation, and traversal live in sibling modules that never import `google.adk`, so the same logic is reusable outside an agent. + +## Get started + +The toolset needs no third-party library beyond `pyyaml`, which ADK already depends on, so there is no extra to install: + +```shell +pip install google-adk +``` + +A bundle is an ordinary directory tree. Reserved filenames (`index.md`, `log.md`) are indexes and history, not concepts: + +```text +knowledge/ +├── index.md +├── metrics/ +│ ├── gross-margin.md +│ └── revenue.md +├── policies/ +│ └── revenue-recognition.md +└── tables/ + └── orders.md +``` + +Each concept opens with frontmatter, then prose: + +```markdown +--- +type: Metric +description: Gross margin as booked by finance. +tags: [finance, margin] +verified: + - by: human:controller + at: 2026-09-01T00:00:00Z +stale_after: 2027-03-01T00:00:00Z +--- + +# Gross margin + +Revenue minus cost of goods sold, reported per period. +``` + +Hand the toolset to an agent: + +```python +from google.adk.agents import LlmAgent +from google.adk.integrations.okf import OkfToolset + +agent = LlmAgent( + name="knowledge_agent", + instruction=( + "Answer from the knowledge bundle. Start with okf_index to find" + " candidate concepts, read only the ones you need, and cite the" + " concept path in your answer." + ), + tools=[ + OkfToolset(bundle="./knowledge", tool_name_prefix="okf"), + ], +) +``` + +`tool_name_prefix` yields the tool names `okf_index`, `okf_read`, `okf_resource`, and `okf_search`. The toolset also accepts the standard `BaseToolset` arguments (`tool_filter`, for instance) and a `now` clock, which is what the staleness tests inject. + +## How it works + +### Four tools, one filter + +| tool | level | returns | +| --- | --- | --- | +| `okf_index` | L1 | one metadata row per matching concept — never a body | +| `okf_read` | L2 | one concept's frontmatter and markdown body | +| `okf_resource` | L3 | a file attached to a concept, capped at 64 KiB | +| `okf_search` | — | concepts whose frontmatter or body matches a query | + +`okf_index` and `okf_search` share a single filter predicate (`directory`, `type`, `tags`, `trust_tier`, `include_deprecated`, `include_stale`), so the two can never disagree about which concepts exist. Discovery costs one line per concept; a body is fetched only once the model has chosen it. + +`okf_search` is a deterministic, case-insensitive substring or regex scan. There are no embeddings, no network calls, and no ranking: given the same bundle and query it returns the same rows in the same order, which is what makes the tool testable and its results citable. + +### Derived, never stored + +Trust tier, lifecycle, and staleness are recomputed from frontmatter on every read; the bundle holds signals, not verdicts. A missing `status` reads as `stable`, an unknown status also reads as `stable` (the spec forbids rejecting a concept for it), and a `stale_after` without a timezone is treated as absent rather than guessed at. + +### Paths resolve inside the bundle or not at all + +Every path argument — `okf_read`'s `path`, `okf_resource`'s `concept_path` and `file` — goes through one guard. A leading `/` means *bundle*-relative, never host-absolute. `..` traversal and symlinks that leave the bundle root are refused. For bundles that write root-relative resource paths without the leading slash, `okf_resource` tries the concept's own directory first and the bundle root second; both attempts pass through the same guard, and a refusal is never retried by the other route. + +Eager loading enforces the same boundary: a symlinked concept that escapes the root is recorded as a violation instead of being parsed, so a hostile file cannot smuggle host content in before any tool is called. + +### Failures are results, not exceptions + +An exception raised inside a tool reaches the model as an opaque failure. These tools return structured errors instead: `{"error": "not_found" | "unsafe_path" | "invalid_argument" | "unreadable" | "invalid_regex" | "internal_error", "message": ...}`. A malformed bundle is reported the same way — as a `violations` list on `okf_index` — so one bad file never hides the rest of the corpus. + +## Security model + +A bundle is untrusted input: it is written by whoever produced the corpus, not by the agent's operator. + +- **Concept bodies and resource text are data, never instructions.** Every tool description says so, and `okf_read` and `okf_resource` mark their payloads with `content_is_untrusted_data: true`. Text inside a concept that impersonates the user, the system, or a tool request is content to report, not a command to follow. +- **Trust tiers are advisory.** `verified` is a claim made by the bundle. The tier it produces filters discovery; it never authorises an action, and no code path gates on it. +- **The toolset is strictly read-only.** It executes nothing from the bundle — no scripts, no attested computations, no network. `agent`, `executor`, and `attester` frontmatter is surfaced as fields for the model to reason about, not run. + +## Testing + +`tests/unittests/integrations/okf/` covers the parser, trust derivation, traversal, and the four tools, including an adversarial suite for traversal, symlink escape, and prompt-injection labelling. The four published OKF sample bundles are vendored under `fixtures/bundles/` (provenance in `PROVENANCE.md`) so the suite stays offline and deterministic. diff --git a/src/google/adk/integrations/okf/README.md b/src/google/adk/integrations/okf/README.md new file mode 100644 index 00000000000..c431edf58e7 --- /dev/null +++ b/src/google/adk/integrations/okf/README.md @@ -0,0 +1,45 @@ +# OKF (Open Knowledge Format) + +Consume an [OKF v0.2](https://github.com/GoogleCloudPlatform/open-knowledge-format) +bundle — a directory of markdown concepts with typed YAML frontmatter — as +progressive, filterable context.
