Summary

  • agents/harness-optimizer.md told the agent to run /harness-audit as if it were a skill under skills/, but /harness-audit is a command backed by scripts/harness-audit.js, and subagents cannot invoke slash commands during their own run.
  • Reworked the agent's workflow and output contract to be a direct derivative of skills/eval-harness/SKILL.md's own methodology (EVAL DEFINITION / EVAL REPORT, Grader Types, pass@k / pass^k) instead of an ad-hoc scorecard.
  • Restructured the body to match the agent template in CONTRIBUTING.md (Your Role, Workflow with Step 1/2/3, Output Format, Examples).

Testing

  • npx markdownlint-cli 'agents/harness-optimizer.md' --ignore node_modules — clean
  • node scripts/ci/validate-agents.js — validated all 67 agent files, no errors

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • Documentation
    • Updated harness optimization guidance to use evaluation-driven grading, including pass@k and pass^k metrics.
    • Added instructions for baseline audits, structured evaluations, regression testing, reporting, and readiness status.
    • Clarified that changes should be minimal, reversible, and automatically restored if verification fails.
    • Documented required capability and safety checks, including human approval for security-sensitive changes.
    • Clarified that audits should use the supported script rather than direct slash-command invocation.

Walkthrough

The harness optimizer prompt now defines eval-driven optimization with baseline auditing, reversible configuration changes, regression verification, pass@k/pass^k calculations, and human approval for security-sensitive changes.

Changes

Harness optimization prompt

Layer / File(s) Summary
Eval-driven optimization workflow
agents/harness-optimizer.md
Updates the role and workflow to run the audit script, define capability and regression evals, restrict changes to harness surfaces, restore failed changes, verify with the grader and test suite, calculate pass@k/pass^k, and produce structured reports.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 6544b

The agent’s evaluation workflow can skip repeated trials for safety-critical regressions that are not hooks and lacks a consistent per-trial pass/fail threshold, which may produce unreliable acceptance decisions. The PR is not merge-ready until these requirements are corrected or explicitly accepted.

Add platform-specific verification before SHIP IT.

The prompt requires preserving behavior across Claude Code, Cursor, OpenCode, and Codex, but verification only mandates the generic audit and node tests/run-all.js. Unless that test command explicitly covers all four integrations, a platform-specific regression can still produce a false SHIP IT.

Add per-platform fixtures/checks, or require READY FOR REVIEW/BLOCKED when a platform cannot be validated.

The PR addresses a missing or misaligned reference in the harness-optimizer.md, updating the description to correctly point to the eval-harness skill. These changes provide a clearer, more accurate context about the functionality by referencing eval-driven grading metrics, which improves clarity and ties the agent to relevant skills. The edits align with contribution guidelines, and the patch seems self-contained and non-breaking. Nicely done!

Addresses CodeRabbit review findings on PR affaan-m#2633: security-sensitive
diffs must stay BLOCKED until a human explicitly approves (no more
SHIP IT on flagged-but-unreviewed changes), and Step 2/3 now snapshot
the pre-change state and auto-restore it if the audit or test suite
fails, so a failed run never leaves the harness partially modified.

Addressed both CodeRabbit findings in cc9b204:

  • Human approval gate: Step 3 / Output Format now require any security-sensitive diff to stay BLOCKED until a human explicitly approves it — it can no longer report SHIP IT just because it was "flagged". Explicitly calls out rejecting broader tool permissions, credential/secret access or exfiltration, and weakened safety controls, and requires checking prompt-injection resilience, permission scope, destructive-action guards, and secret-exfiltration risk for {skills,commands,agents,rules}/** changes.
  • Reversibility: Step 2 now snapshots the target paths before editing and keeps the diff allowlisted to the leverage area under test; Step 3 auto-restores that snapshot if the audit or node tests/run-all.js fails, and the output reports the final diff so a failed run never leaves the harness partially modified.

Verified: npx markdownlint-cli 'agents/harness-optimizer.md' clean, node scripts/ci/validate-agents.js (67 agents) clean, node tests/run-all.js 3385/3385 passed.

Enforce the TDD and coverage gates.

The workflow runs tests after edits, but it does not require a RED test before implementation or enforce at least 80% coverage. Passing node tests/run-all.js alone can produce a successful report that violates the repository acceptance criteria.

Add the pre-change test/eval step. Treat coverage below 80% as a Code-Based failure. Include the coverage result in EVAL REPORT.

As per coding guidelines, write tests before implementation, follow the RED-GREEN-IMPROVE TDD workflow, and maintain at least 80% coverage.

Define the post-approval status and approval record.

Line 47 says a security-sensitive diff “may never report SHIP IT”, but it also says it remains BLOCKED only until human approval is recorded. These rules do not define a valid status after approval.

State whether approval permits promotion. If it does, prohibit SHIP IT only before approval. If it does not, define the post-approval status. Require a trusted, machine-checkable approval record. Do not accept an agent-written claim as approval.

Thank you for the careful follow-up, and sorry for the wait. This now fixes the missing slash-command assumption, anchors optimization in the existing eval-harness contract, keeps changes scoped and reversible, and requires human approval for security-sensitive results. I verified Markdown lint, agent validation, the documented harness-audit.js repo --format json entry point, JSON output, and diff cleanliness at the exact head cc9b204. This is ready to merge after the exact-main and PR-head gates are green.

Thank you again for fixing the broken slash-command assumption and grounding this agent in the eval-harness contract. During final integration I found one small ambiguity: the prompt requested pass@3 and pass^3 without requiring three trials. I pushed a maintainer follow-up that names the exact grader command, requires three independent capability trials, requires all three safety-critical regression trials to pass, and records every result. Markdown lint, agent validation, the harness audit JSON entry point, and diff checks pass. Once the refreshed PR checks are green, this is ready for the serial main merge gate.

Apply pass^3 to every safety-critical regression eval.

Line 39 limits the three-trial all-pass rule to “safety-critical hook regression evals”. A safety-critical regression for prompt-injection resilience, tool permissions, destructive-action guards, or secret exfiltration can avoid pass^3 when it is not implemented as a hook. The eval-harness contract applies pass^3 to critical paths generally. (github.com)

Change the rule to cover every safety-critical regression eval.

-run each safety-critical hook regression eval in three independent trials

Define a Model-Based Grader gate.

Require each capability trial to record the four contract questions, a 1–5 score, reasoning, and a pass threshold. The current self-assessment does not provide a defined per-trial pass/fail result.

Greptile Summary

This change replaces unusable slash-command guidance with direct harness-audit execution and adds an eval-driven workflow for configuration improvements. Two issues need correction in agents/harness-optimizer.md: the rollback guidance cannot restore pre-existing untracked work, and the example report contradicts the required three independent capability trials. The snapshot procedure should explicitly preserve untracked paths, and the example should record three trials and report pass@3.

Confidence Score: 3/5

Do not merge until the rollback instructions preserve untracked work and the example reflects the mandatory reliability evaluation.

Focused executable checks reproduced two independent documentation failures: default Git snapshot methods omit untracked files, and the example fails its own required three-trial reporting rule.

Files Needing Attention: agents/harness-optimizer.md lines 35 and 55 need updates.

T-Rex T-Rex Logs

What T-Rex did

  • T-Rex produced a P1 finding proof about restoring harness files with an include-untracked git stash, and provided a reproduction script.
  • T-Rex produced a P1 finding proof validating a focused reporting-rule workflow, with a focused validation source and results showing a failing example and a passing control.
  • T-Rex produced a P1 finding proof describing a before/after git state experiment where including untracked files with stash restores both the tracked edit and untracked harness.
  • T-Rex produced another P1 finding proof.
  • T-Rex produced a P1 finding proof about a general contract-validation proof related to harness-optimizer targets and trial requirements.

    P1 Default snapshot guidance cannot exactly restore untracked harness files

    • Bug
      • At agents/harness-optimizer.md:35, the example snapshot methods use default git diff and git stash create. In the executed failure path, neither captured harness-untracked.txt; cleanup removed it permanently, so the instructions cannot meet the stated exact-restoration guarantee when a pre-existing untracked file is in scope.
    • Cause
      • Default git diff reports tracked-file changes only, and default git stash create creates a stash for tracked/index changes without an untracked-files tree.
    • Fix
      • Replace the ambiguous default commands with a snapshot method that explicitly includes untracked files and a documented restoration command, such as git stash push --include-untracked followed by git stash apply --index; alternatively use an explicit copy/archive that includes every intended path.

  2. General comment

    P1 Example allows a capability report without the mandated three-trial reliability evaluation

    • Bug
      • The line-55 example reports hooks-latency as pass@1 and contains neither three independent trial results nor pass@3. This creates an example path that permits skipping the repeated capability evaluation that line 39 makes mandatory.
    • Cause
      • The example output was not updated to reflect the three-trial/pass@3 reporting rule in Step 3.
    • Fix
      • Revise the line-55 example to record three independent hooks-latency trial outcomes and report pass@3 (or explicitly make the example a pre-rule illustration, if that is intended).

### Issue 1
agents/harness-optimizer.md:35
**Rollback snapshots omit untracked files**

The suggested `git diff` and `git stash create` snapshots do not capture untracked paths. If verification fails and cleanup is needed, a pre-existing untracked harness file cannot be restored exactly and may be removed by destructive cleanup. Use a snapshot method that explicitly includes untracked paths and document its restoration command.

### Issue 2
agents/harness-optimizer.md:55
**Example skips required repeated trials**

The example reports only `pass@1`, even though Step 3 requires three independent capability trials, recording every result, before reporting `pass@3`. Following this example permits a reliability claim without the repeated evaluation the workflow requires. Record three trial outcomes in the example and report `pass@3`.

### Step 2: Execute

## Output
Before touching any file, snapshot the current state of every path you intend to change (e.g. `git diff` / `git stash create` baseline, or a copy of the file) so it can be restored exactly. Propose and apply minimal, reversible configuration changes per identified leverage area, keeping the diff allowlisted to the leverage area under test — no incidental edits. Preserve cross-platform behavior across Claude Code, Cursor, OpenCode, and Codex, and avoid fragile shell quoting.

P1 Rollback snapshots omit untracked files

The suggested git diff and git stash create snapshots do not capture untracked paths. If verification fails and cleanup is needed, a pre-existing untracked harness file cannot be restored exactly and may be removed by destructive cleanup. Use a snapshot method that explicitly includes untracked paths and document its restoration command.

Rule Used: Review for prompt injection, tool-permission creep... (source)

Artifacts

Reproduction script for tracked and untracked Git snapshot restoration

  • An authored isolated-Git test script creates a tracked edit and pre-existing untracked harness file, exercises default and include-untracked snapshot paths, and asserts restoration results; it provides the repeatable proof procedure.

Default git diff and git stash create omit the untracked harness file

  • Output from the default snapshot failure-path run shows only tracked.txt in both the diff and stash tree, then confirms cleanup left the untracked harness file unrestored; the documented default path is destructive for that file.

Include-untracked stash restores the tracked edit and untracked harness file

  • Output from the include-untracked comparison run confirms the restored worktree contains both the tracked edit and harness-untracked.txt; explicit untracked-file capture preserves exact restoration.

Input: `node scripts/harness-audit.js repo --format json` reports a PreToolUse hook exceeding the 200ms budget.
Action: Define a Regression Eval for the existing hook tests, move the slow check to an async PostToolUse hook, then re-run the audit and `node tests/run-all.js`.
Output: `EVAL REPORT: harness-optimization` with Capability Eval `hooks-latency` at pass@1, Regression Evals unaffected, Status: SHIP IT.

P1 Example skips required repeated trials

The example reports only pass@1, even though Step 3 requires three independent capability trials, recording every result, before reporting pass@3. Following this example permits a reliability claim without the repeated evaluation the workflow requires. Record three trial outcomes in the example and report pass@3.

Artifacts

Focused reporting-rule validation source

  • Authored Python source reads the specified instruction lines and evaluates the example and compliant control report against the three-trial pass@3 rule; it provides executable validation evidence.

Example output fails the mandatory three-trial reporting rule

  • Captured command output for the actual line-55 example shows zero recorded trials, pass@1, no pass@3, and a noncompliant result; the example is not permitted by line 39.

Three-trial pass@3 control report satisfies the reporting rule

  • Captured command output for a comparable report with three recorded passing trials and pass@3 succeeds; this confirms the rule scope and required reporting shape.
