policy-drift-audit

policy-drift-audit is a skill for Claude Code, Codex from Detective-XH/DocGraph. It costs 50 tokens per session (827 once invoked), scanned A, original, MIT.

A DocGraph audit that finds policy and process documents that are outdated, replaced, duplicated, unofficial, or contradictory.

In plain words
What is it for?
Checking whether policy documents need review, replacement, archiving, or other follow-up.
Why use it?
It helps teams spot conflicting or stale guidance before people rely on the wrong document. Its findings are suggestions for human review, not final governance decisions.

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

policy-drift-audit 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 9d 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.

Policy/Process Drift Audit

Invocation — Claude Code: Skill("policy-drift-audit") | OpenCode / Codex: use triggers above.

Runs the DocGraph policy/process drift audit and presents findings for human review. The audit is advisory — findings highlight candidates for action, not authoritative rulings.

Execution

  • Model: Haiku (query) → Sonnet (remediation suggestions if requested)
  • Effort: Low
  • Advisor: Not required
  • Core computation: done by DocGraph's GetDriftFindings engine, not by this skill

Step 1: Check index status

docgraph_status

Confirm:

  • policy_process pack is listed under Domain Packs
  • Governance metadata is indexed (docs with metadata > 0)

If policy_process is not listed, the binary is too old or the pack was never registered — tell the user to upgrade DocGraph and run docgraph index --force.


Step 2: Run the drift audit

docgraph_context task="policy/process drift audit" format=drift_audit

This calls DocGraph's GetDriftFindings engine, which checks:

Code Meaning
policy.stale_review review_due date has passed; status is not archived/superseded
policy.superseded_referenced A superseded document is still referenced by an active document
policy.duplicate Two approved documents are highly similar (≥ 0.75 similarity)
policy.non_canonical Multiple active documents claim the same canonical_source
policy.conflicting Competing active authorities on the same topic, or conflicting supersedes claims

Step 3: Present findings to the user

Group findings by severity (errors first, then warnings).

For each finding:

  1. State the file path(s) and finding code
  2. Show the message and evidence from the finding
  3. Suggest a concrete remediation (below) — but do NOT make the change without confirmation

Remediation patterns

Code Suggested action
policy.stale_review Update review_due in frontmatter, or change status to archived if retired
policy.superseded_referenced Update the citing document to reference the newer version instead
policy.duplicate Merge or archive one copy; ensure one declares itself canonical_source
policy.non_canonical Resolve which copy is authoritative; archive or update canonical_source on the others
policy.conflicting Determine which document holds authority; update status/supersedes/superseded_by accordingly

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.
