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 | $0.00041 | $0.01161 |
| Opus 5.5 | $0.00016 | $0.00464 |
| Sonnet 5.5 | $0.00008 | $0.00232 |
| Haiku 4.5 | $0.00004 | $0.00116 |
Grade A, and why
harness-help 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 10d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/harness-help
You don't remember every skill, so ask. Most work travels one main flow;
everything else is standalone. Each skill below is documented in its own
skills/<name>/SKILL.md (core) or extras/skills/<name>/SKILL.md — this router
only says when to reach for which.
The main flow: idea → shipped
/spec <slug>— turn a fuzzy request intospec.md+plan.mdunder.agent/plans/<slug>/, then route to plan approval (ExitPlanMode). Add--interviewwhen the request is fuzzy enough that a wrong guess would commit the spec to the wrong shape, or--score-candidateswhen the field of problems/approaches is wide enough that the pick should be scored, not asserted. Approval is what unlocks editing —spec-gatestops asking once the plan-approval flag exists./supervise <slug>— run the approved plan wave by wave, dispatching specialists per the delegation contract and auditing after each wave.--goal-modefor budgeted, resumable runs./verify-completion <claim>— before accepting any "done": a fresh context re-checks the claim mechanically, then a refute-by-default judge./supervisecalls this at its completion step; reach for it directly whenever a builder's word is the only evidence./wrap— commit + PR with the safety gates (gitleaks, risk areas) intact.--auto-push/--auto-mergeare opt-in escalations.
A single small edit needs none of this — just make the edit; the gates scope trivial work out by design.
Standalone
/council-review [--staged|--head|<range>]— multi-vendor second opinion on a diff (Claude reviewer plus codex/gemini lanes), synthesized with citation checks./project-init(command) — scaffold a consumer project withCLAUDE.md, rules, andgitleaks.toml.- Security — diff-level security review is the
security-revieweragent (auto-dispatched on risk paths); a whole-repository or branch vulnerability scan is the official/claude-securityplugin when installed (/plugin install claude-security@claude-plugins-official).
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.

harness-help is a skill published in the GitHub repository joymin5655/Agent (2 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 1,161 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
