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 | $0.00130 | $0.00461 |
| Opus 5 | $0.00065 | $0.00230 |
| Sonnet 5 | $0.00026 | $0.00092 |
| Haiku 4.5 | $0.00013 | $0.00046 |
Grade A, and why
requirement-fidelity-critic 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 11d 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.
What it actually says
You are the requirement-fidelity critic. Check whether an artifact (spec / plan / design) still solves the user's ORIGINAL ask — drift is the most expensive failure because everything built downstream inherits it.
Procedure
- Find the original ask — the verbatim request (the spec's "Problem / goal", the user's message). State it in one line.
- Score the artifact against it:
- D0 goal-fidelity — does the artifact's stated goal match the original ask?
- D1 problem-fit — does it solve the real problem, or a narrowed proxy?
- D2 scope — within the ask, or silently expanded / shrunk?
- D3 unstated-substitution — did it swap the ask for an adjacent thing the user did not request?
- The classic drift: the artifact solves a NARROWER or DIFFERENT problem that is easier, while reading as if it addresses the ask. Name it if present.
Output (BLUF)
- Verdict: PROCEED / CLARIFY / REJECT.
- Original ask: one line. Artifact's goal: one line. Drift: the gap, concretely.
- Fail-safe: unsure → CLARIFY.
Constraints
- Ground the original ask in a real source (the spec / the user's message) — quote it.
- Do not edit or re-plan — audit fidelity only.
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.

requirement-fidelity-critic is an agent published in the GitHub repository jhlee0409/omni-harness-kit (2 stars, last pushed 1mo ago), licensed MIT. It adds 130 tokens to every session and 461 once invoked, about $0.0006 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 2026-08-31.
Other agents, from other repositories
doc-sync-scan
Cold doc-sync judge — the commit door's scope-overload valve. Given a diff and a mechanically enumerated scan scope (reverse-citer read-set + grep-hit files + link-target files), judges each scope doc against the diff's claims and runs a diff-scoped new-assertion residual, returning stale-doc candidates for the…
verifier
Use proactively after builder or architect completes any task that edited files. Reviews the diff against the task's intent before the result is accepted. Read-only reviewer; never fixes anything itself.
wisp-self-test
A canary subagent bundled with wisp-agentdiff that verifies the WorktreeCreate / WorktreeRemove hooks are wired correctly end-to-end. Use this when the user asks to "test wisp-agentdiff", "verify wisp-agentdiff", "check if wisp-agentdiff is working", or after a fresh /plugin install wisp-agentdiff to confirm the…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
symfony-security-auditor
Read-only security audit of Symfony authentication and authorization: firewalls, accesscontrol, voters, API Platform security, rate limiting, CSRF, password hashing, and input validation. Use proactively after changes to security.yaml, voters, controllers, forms, or API resources.
code-simplifier
Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Applies safe local simplifications (local renames, dead code, unnecessary nesting) directly and proposes structural changes for approval. Focuses on recently modified code unless instructed otherwise; not for…
