Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00134 |
| Opus 5.5 | $0.00013 | $0.00054 |
| Sonnet 5.5 | $0.00007 | $0.00027 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
local-mode-verification 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 1mo 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.
This is a copy
88% identical to final-local-product-review — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
local mode verification
Follow the repository source-of-truth docs. Do not expand product scope, enable real-world effects, use real PII, or weaken tests/invariants. Produce evidence for any claim of completion.
Workflow
- Read the relevant docs/harness and product-execution contracts.
- Inspect current implementation.
- Make the smallest safe change needed for the active task.
- Run the relevant checks.
- Record evidence and remaining risks.
What this file has done since we first saw it
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.

local-mode-verification is a skill published in the GitHub repository ryne2010/harness-engineering-audit (5 stars, last pushed 1mo ago), licensed MIT. It adds 33 tokens to every session and 134 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 88% identical to final-local-product-review, differing in 6 lines, and is treated as a copy.
Other skills, from other repositories
debugging-diagnosis
Diagnose and fix bugs through reproduction, minimization, hypotheses, instrumentation, targeted fixes, and regression coverage. Use when the user reports failing behavior, a broken test, runtime error, flaky workflow, or asks for debugging before implementation.
test-first-implementation
Implement behavior with a red-green-refactor loop, observable tests, and small vertical slices. Use when the user asks for TDD, test-first work, regression-first fixes, or a feature that needs clear behavior before implementation.
debug
Systematic debugging when a failure's cause is unknown: reproduce first, isolate, fix the root cause once, prove it with a regression test. Use when a bug, crash, failing test or wrong output has no obvious cause, when a fix attempt did not work, or before claiming a stubborn bug fixed. For production incidents…
verify
Prove a change actually works before it counts as done. Use after building any non-trivial change, before deliver, and whenever claiming something works. Exercises real behavior end-to-end. Green tools alone are not verification.
layerkit-fix-from-dry-run
Fix failed integration verification from logs, tests, and docs evidence; edit real package files, no invention.
harness-engineering-playbook
Implement OpenAI Harness Engineering practices in any repository — AGENTS.md, PLANS.md, deterministic smoke/test/lint harness commands, strict architecture boundaries, observability from day 1, and entropy-control audits for reliable autonomous agent runs.
