Emit a stderr warning for ec validate vsa, explicit VSA image flags, and vsa report output. Document the deprecation while keeping existing VSA behavior available.

📝 Walkthrough

VSA command usage now produces a deprecation warning, and CLI help marks VSA options as deprecated. Documentation describes the deprecation scope, continued availability, warning behavior, and recommended integration path.

Risk Assessment: moderate (2/5)

Details

Tier 1 signals unchanged from prior review (avg ~2.38): two protected-path edits, zero test-file ratio per script despite new snapshot, medium blast radius across 14 files. Tier 2 improved slightly (avg ~2.3 vs prior 2.67): 3 distinct authors in 90-day window on core changed files, no regressions or reverts. Sole incremental commit adds acceptance test snapshot for VSA deprecation warnings. Composite 0.62x2.38+0.38x2.3=2.35 rounds to 2.

Risk Assessment: moderate (2/5)

Details

Tier 1 average 2.38 (two max-scoring dimensions: 2 protected-path edits and 0.00 test-file ratio despite 3 Go source files touched). Tier 2 average 2.67 (7 distinct authors in 90d on changed files). No Tier 3 (Jira EC-2006 inaccessible). Weighted composite 2.49 rounded to 2. Functional scope is narrow (stderr warnings + docs), low-complexity Go additions, majority of lines are in documentation.

Review

Findings

Medium

• [protected-path] .cursor/rules/vsa_functionality.mdc, AGENTS.md — The PR modifies protected governance paths. The PR description explains the rationale (VSA deprecation stderr warnings and documentation) and references Jira EC-2006. Human approval is always required for protected-path changes, regardless of context.

Review

Findings

Medium

• [protected-path] .cursor/rules/vsa_functionality.mdc, AGENTS.md — This PR modifies files under protected governance paths. The edits (adding a deprecation banner to .cursor/rules/vsa_functionality.mdc and updating the DESIGN.md pointer in AGENTS.md) are consistent with the broader VSA deprecation work described in the PR body (Ref: EC-2006). Human approval is always required for protected-path changes, regardless of context.

The codecoverage is right in that the paths with warnings are untested, otherwise lgtm.

Retro: PR #3629 — feat(validate): warn on deprecated VSA usage

This was a human-authored PR by joejstuart adding deprecation warnings for VSA functionality across 14 files (124 additions, 19 deletions). The workflow executed cleanly with no rework iterations.

Timeline

1. Oct 21 18:26 — PR opened with two commits (feat + test snapshots).
2. Oct 21 18:26–18:37 — First review run (39652733250): 6 sub-agents dispatched (correctness, security, intent-coherence, style-conventions, docs-currency, risk-assessment). Challenger correctly removed 2 false positives and downgraded 2 findings. One medium protected-path finding filtered by REVIEW_FINDING_SEVERITY_THRESHOLD=high. Cost: $4.93, runtime 6m55s.
3. Oct 21 19:02–19:12 — Second review run (39658035952): Re-review with narrowed scope (skipped security, docs-currency, cross-repo-contracts). 3 style findings (medium/low/info) all filtered. 0 findings surfaced. Efficient scope narrowing.
4. Oct 21 20:59 — simonbaird approved.
5. Oct 22 13:30 — jsmid1 approved, noting: "The codecoverage is right in that the paths with warnings are untested, otherwise lgtm."
6. Oct 23 15:18 — PR merged.

Workflow quality

Overall: Good. No rework, efficient re-review, correct challenger adjudication, and appropriate human review gate via requires-manual-review label.

Challenger performance (positive): Correctly removed a false-positive code-duplication claim about imageCommandUsesVSA vs parseOutputSpec — the challenger read the actual code and determined that strings.Cut('?') followed by strings.Cut('=') is not equivalent to strings.Cut('=') alone. Also correctly removed a missing-authorization finding since the Jira EC-2006 reference was present.

Re-review optimization (positive): The second run correctly narrowed scope after recognizing the prior review was clean and the incremental delta was one snapshot file, saving ~30% on sub-agent cost.

Judge scores

Score	Candidate	Disposition
3/5	Risk-assessment TEST_FILE_RATIO signal not reaching correctness sub-agent	Summary-only (duplicate of fullsend-ai/agents#1468)
1/5	Style finding about attestation-format flag semantics	Summary-only (one-off design choice)
1/5	Protected-path finding filtered but label still enforced human review	Summary-only (working as designed)
0/5	Re-review scope narrowing efficiency	Summary-only (positive signal)

Evidence for existing issues

• fullsend-ai/agents#1468 — Additional evidence: The risk-assessment sub-agent scored TEST_FILE_RATIO at 4–5 (new file vsa_deprecation.go with ~95% patch coverage but no dedicated unit tests), yet the correctness sub-agent reported 0 findings on test adequacy. Human reviewer jsmid1 independently identified the same gap. This confirms the structural disconnect described in build(deps): bump the all group with 1 update #1468 where risk-assessment churn/coverage signals have no path to influence the correctness sub-agent's test-adequacy evaluation.

No proposals filed

The one candidate with recurring-impact potential (risk-assessment signal disconnect, score 3/5) is already covered by fullsend-ai/agents#1468. All other candidates scored ≤1/5. The workflow functioned well overall.
