verify-readme-features

verify-readme-features is a skill for Claude Code, Codex from rlespinasse/agent-skills. It costs 61 tokens per session (1,346 once invoked), scanned A, original, MIT.

A codebase audit that checks whether features described in a README, a file that explains a project, are actually implemented. It compares each documented claim with the relevant source code.

In plain words
What is it for?
Use it to verify README feature lists, onboarding documentation, and other feature descriptions against the implementation.
Why use it?
It helps find documentation that promises features the project does not have, or describes them inaccurately. This is useful before releases and after refactoring.

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

verify-readme-features 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 12d 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.

Verify README Features

You are helping the user verify that every feature claim in their project's README (or similar documentation file) is backed by actual implementation in the codebase.

When to Use

  • After updating a feature list in documentation
  • Before a release, to ensure docs match reality
  • When onboarding to a project and wanting to trust the README
  • When refactoring or removing features that may still be documented

Verification Process

Step 1: Identify Feature Claims

  1. Read the documentation file (default: README.md in the project root)
  2. Extract each feature claim — every bullet point, heading, or sentence that describes a capability of the project
  3. Note specific sub-claims — if a feature says "with X, Y, and Z", each of X, Y, and Z is a separate claim to verify

Step 2: Search the Codebase

For each feature claim:

  1. Identify keywords — extract the key terms that would appear in an implementation (function names, config keys, CSS classes, module names)
  2. Search source files — use grep/glob to find implementations matching those keywords
  3. Read the relevant code — confirm the implementation matches the claim, not just the name
  4. Note the evidence — record the file path and line number(s) where the feature is implemented

Step 3: Classify Each Claim

Assign one of these statuses:

Status Meaning
Confirmed Implementation found that matches the claim
Partial Implementation exists but does not fully match the claim
Not found No implementation found for this claim
Overstated Implementation exists but the claim exaggerates its capabilities

Step 4: Report Results

Present results in a summary table grouped by documentation section, with columns:

Feature Status Evidence

Where:

  • Feature: the claim as written in the documentation
  • Status: one of the statuses from Step 3
  • Evidence: file path and brief description of what was found (or what is missing)

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.
