DeepReason: Skill for Claude Code

.claude/skills/dr-audit-spec-drift/SKILL.md

dr-audit-spec-drift is a skill for Claude Code from AHepi/DeepReason. It costs 53 tokens per session (834 once invoked), scanned A, original, MIT.

An audit that compares a project’s code with its specification documents in both directions.

In plain words
What is it for?
Use it to scan specification terms and shipped code surfaces, record orphaned or undocumented items, and save evidence for the audit.
Why use it?
It reveals when code no longer matches the specification and when public code features are missing from the specification.

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

dr-audit-spec-drift 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 6d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Audit: code vs spec

Entry: LEDGER.md exists, spec-drift.md missing. Exit: spec-drift.md written, LEDGER rows added, proofs in proof/.

Two directions, both mechanical:

  • SPEC→TREE: a term the spec names that the tree no longer honors = the code deviates from spec.
  • TREE→SPEC: a shipped public surface the spec never mentions = the spec is behind the code.

The spec series is every docs/harness-spec-*.md (base + all amendments — read ALL amendments; later files supersede earlier ones on conflict, so verify a term against the newest file naming it).

Operations

  1. SPEC term census: rg -o -N '\x60[A-Za-z_][A-Za-z0-9_.:-]*\x60' docs/harness-spec-*.md | sort -u > proof/spec-terms.txt plus every ##-level heading noun phrase. This is the SPEC list.
  2. For each SPEC term: rg -l -w '<term>' src/deepreason/ (identifiers) or rg -l '<term>' src/ docs/map/ (concept phrases). Zero hits → verdict spec-orphan (spec names it, tree does not have it), one row each with the scan saved. Hits → tally only.
  3. TREE surface census, three lists with proofs: a. CLI flags: rg -o -N '"--[a-z][a-z0-9-]*"' src/deepreason/cli/main.py | sort -u b. Config fields: rg -o -N '^ [A-Z][A-Z0-9_]*:' src/deepreason/config.py | sort -u c. Typed error/refusal strings: rg -o -N '"[A-Z][A-Z0-9_]{6,}"' src/deepreason/run_manifest.py src/deepreason/preparation.py | sort -u
  4. For each TREE surface item: rg -l -F '<item>' docs/harness-spec-*.md. Zero hits → verdict spec-silent (shipped, undocumented in spec), one row each. Batch rows by feature, not per flag, when one tranche shipped them together (the row names the batch and lists members).
  5. Write spec-drift.md: two tables (one per direction) with count lines. The spec-silent table's parked prompt is a spec-amendment draft request (append-only amendment file, never an edit to existing spec text), route dr-change-orchestrator.

GATE

Pass: proofs exist for both censuses; every spec-orphan and every spec-silent row cites its scan file; count lines match row counts. Verdict labels: spec-orphan | spec-silent | covered.

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.

dr-audit-spec-drift is a skill published in the GitHub repository AHepi/DeepReason (142 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 834 once invoked, about $0.0003 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.
