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 | $0.00083 | $0.01504 |
| Opus 5 | $0.00042 | $0.00752 |
| Sonnet 5 | $0.00017 | $0.00301 |
| Haiku 4.5 | $0.00008 | $0.00150 |
Grade A, and why
verify-rfc 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 3d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RFC Verification
You are verifying a design document (RFC, spec, design doc) against the actual implementation. Identify completeness, gaps, and discrepancies.
Input
Determine the RFC, design doc URL, or topic from the user's request. If it is not clear, ask: "Which RFC or design doc would you like to verify? You can give me a URL, a document title, or a topic to search for."
Core Principles
- Thorough but efficient: Don't over-analyze trivial items
- Quote evidence: Show specific code when claiming implementation exists
- Be skeptical: Just finding related code doesn't mean the requirement is met
- Honesty over completeness: Better to say "couldn't verify" than claim incorrectly
Phase 1: Fetch the Design Document
Goal: Get the full RFC content
Actions:
-
Get the document:
- If given a URL:
read_document "[URL]" - If given a topic:
search "[topic] RFC OR design doc"thenread_documenton the best match
- If given a URL:
-
Extract verifiable requirements:
- Functional requirements
- Technical specifications
- Integration points
- Non-functional requirements (performance, security)
-
Create a checklist of requirements to verify
Phase 2: Search the Codebase
Goal: Find implementations for each requirement
Actions:
-
For each major requirement area, search the local codebase using your host's local file-search tools (grep/glob/read) to find relevant files by name patterns, locate specific implementations, and examine implementation details.
-
Also search Glean for related internal code:
code_search "[requirement] implementation" -
Document what you find for each requirement
Phase 3: Vet Each Finding (CRITICAL)
Goal: Rigorously verify claims — BE SKEPTICAL
For each requirement × implementation pair, evaluate:
Match Quality Test
- Does the code actually implement this requirement?
- ✅ IMPLEMENTED: Clear, direct implementation with evidence
- ⚠️ PARTIAL: Some aspects present, others missing
- ❓ UNCLEAR: Code exists but doesn't clearly fulfill requirement
- ❌ NOT FOUND: No evidence of implementation
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.

verify-rfc is a skill published in the GitHub repository gleanwork/claude-plugins (25 stars, last pushed 14d ago), licensed MIT. It adds 83 tokens to every session and 1,504 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.
