audit

audit is a skill for Claude Code, Codex from prebid/salesagent. It costs 48 tokens per session (776 once invoked), scanned A, original, Apache-2.0.

Run a repeatable code review audit on migration changes. Inventories files by architectural layer, reviews each layer against #1050/#1066 principles, and files beads issues for findings. Re-run after remediation batches to track progress.

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

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 2d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Migration Audit

Repeatable code review workflow for auditing migration changes. Produces structured review documents and beads issues for every finding.

Args

/audit [audit-target]

The audit target (optional, defaults to "full"):

  • Branch: KonstantinMirin/adcp-v3-upgrade — review all changes on branch
  • Commit range: main..HEAD — review commits in range
  • "full": Audit entire codebase against architecture principles

What It Produces

  1. Change inventory by architectural layer (schema, business, boundary, transport, adapter, database, test)
  2. Layer-specific reviews against #1050/#1066 checklists
  3. Consolidated report in docs/code-reviews/
  4. Beads issues for every finding not already tracked

Protocol

Step 1: Cook the molecule

python3 .claude/scripts/cook_formula.py \
  --formula .claude/formulas/migration-audit.yaml \
  --var "AUDIT_TARGET={all_args}" \
  --epic-title "Audit: {all_args}"

If no target specified, use "full":

python3 .claude/scripts/cook_formula.py \
  --formula .claude/formulas/migration-audit.yaml \
  --var "AUDIT_TARGET=full" \
  --epic-title "Audit: full codebase"

Dry run first (recommended):

python3 .claude/scripts/cook_formula.py \
  --formula .claude/formulas/migration-audit.yaml \
  --var "AUDIT_TARGET={all_args}" \
  --epic-title "Audit: {all_args}" \
  --dry-run

Step 2: Walk the molecule

bd ready → bd show <atom-id> → execute → bd close <atom-id> → repeat

Linear pipeline: inventory-changes → review-per-layer → consolidate → file-issues → commit-report.

Step 3: Done when report committed

Audit report in docs/code-reviews/, beads issues filed for all findings.

Layer Review Checklists

Each layer has a specific checklist (see formula for full details):

Layer Key Checks
Schema Correct base class, no field duplication, exclude=True on internals
Business No ToolError, no transport imports, ResolvedIdentity, no error dicts
Boundary All _impl params exposed, version compat at boundary only
Transport Shared _impl pattern, no business logic duplication
Database SQLAlchemy 2.0, JSONType, correct column types
Adapter No protocol code, proper error propagation

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.
