docs-grounding-verifier is a skill for Claude Code, Codex from microsoft/apm. It costs 0 tokens per session (1,896 once invoked), scanned A, original, MIT.

A documentation checker that compares specific documentation pages with the source code to see whether each factual claim is supported.

In plain words
What is it for?
Use it to verify one or more pages against code, especially during documentation audits or reviews of documentation changes.
Why use it?
It helps find statements that sound correct but do not match what the code actually does.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents).

This is microsoft/apm's own configuration. It tells Claude Code and Codex how to work on apm itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything apm configures →

About the project

APM is a package manager for AI-agent configuration, using a manifest to declare reusable instructions, skills, prompts, agents, hooks, plugins, and MCP components. Development teams use it to reproduce agent setups across projects and control their dependencies through policies and lockfiles, while the catalogue contains many of these agent components.

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

docs-grounding-verifier 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.

The scan reads SKILL.md. This mod also ships 1 executable file (evals/run-evals.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

docs-grounding-verifier

CLAIM-LEVEL grounding verification. Adapts the RAGAS faithfulness-eval pattern (proven in RAG literature) to docs/code instead of generated- answers/retrieved-context. Source code is the ground truth; docs paragraphs are the candidate text under audit.

python-architect persona doc-writer persona

Sibling contract

This skill is a SIBLING of docs-corpus-audit and docs-sync. The boundary is load-bearing:

Skill Trigger Scope Granularity
docs-sync PR opened/synchronized PR diff only Page-level
docs-corpus-audit Maintainer asks for whole-corpus pass Entire corpus Page-level
docs-grounding-verifier Verify specific pages factually 1..N pages CLAIM-level

docs-corpus-audit invokes this skill in its VERIFY phase on the highest-risk pages of each wave. docs-sync can invoke it on the specific pages in a PR diff. The skill is also runnable standalone.

When to activate

  • Maintainer says "verify against the code".
  • An audit wave wants per-claim grounding scores for its highest-risk pages.
  • A PR review wants to confirm that prose changes are not just plausible but actually consistent with the implementation.
  • A "fact-check" or "grounding" or "drift hunt" request.

When NOT to activate

  • Whole-corpus sweep with no specific page list -> use docs-corpus-audit.
  • PR review with mixed code+docs diff -> use docs-sync.
  • Editorial / tone review -> use editorial-owner persona directly.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
