harness-feedback

harness-feedback is a skill for Claude Code from AnastasiyaW/codex-claude-code-config. It costs 81 tokens per session (875 once invoked), scanned A, original, MIT.

A way to adjust automated checks when they are blocking work or reporting problems that do not fit the check's purpose. It separates quick staging checks, security proof, release checks, and long-running stress tests.

In plain words
What is it for?
Use it when a test, virtual machine, evaluator, or release gate is too strict, overloaded, or producing false positives.
Why use it?
It prevents slow or specialized checks from blocking ordinary testing while keeping important evidence for security and releases.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

harness-feedback scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Harness Feedback

Treat "the harness is too strict" as an engineering finding, not as permission to disable a safety check. Find the boundary that owns the mismatch and move the check to the narrowest profile that actually needs its evidence.

Profiles

Use these profiles unless the project has a more specific, documented contract:

Profile Purpose Typical blocking checks
staging-smoke Fast proof that the changed build starts and the critical path works build, focused regression, one stable smoke/contract check
security-proof Prove an adversarial or trust-boundary claim hostile tests, source/collector proof, fresh-context evaluator
release-attestation Prove the exact releasable artifact and its identity signing, Authenticode/tool identity, installer/package checks
nightly-stress Find intermittent and capacity failures race, stress, AV/OS matrix, long-running evals

staging-smoke must not require signing, production credentials, a release certificate, or a long VM stress run. security-proof may run on an unsigned staging build when its claim is source or runtime behavior. A release check may remain blocking for release promotion without becoming a per-edit gate.

Feedback Loop

For every overload signal, record:

  1. requested profile and change boundary;
  2. gate that blocked or dominated the run;
  3. command, elapsed time, failure count, and evidence actually produced;
  4. whether the gate was relevant, duplicated, flaky, or misplaced;
  5. the smallest profile split or deletion of duplicate coverage;
  6. a before/after run of the affected profile and a fresh review of the rule.

Use the deterministic harness-load-advisor.py signal as an intake event. It stores metadata outside the repository and forces the final report to name the mismatch. Durable policy changes belong in Git; raw session traces do not.

Required Report

Do not write "overkill" and move on. Report:

Harness feedback: OVERLOAD | CLEAR
Requested profile: staging-smoke | security-proof | release-attestation | nightly-stress
Mis-scoped gate: <name>
Evidence: <command, result, elapsed time, or explicit missing proof>
Correction: <profile split or rule change>
Verification: <before/after commands and result>
Residual risk: <what remains intentionally gated and where>

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

harness-feedback is a skill published in the GitHub repository AnastasiyaW/codex-claude-code-config (149 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 875 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
