auto-verify

auto-verify is a skill for Claude Code, Codex from appautomaton/automaton. It costs 18 tokens per session (1,402 once invoked), scanned A, original, MIT.

A final checking workflow for comparing completed software work with its acceptance criteria, meaning the conditions it must satisfy.

In plain words
What is it for?
It helps reread the plan, run proof commands, inspect changes when needed, and report passed, failed, and skipped checks.
Why use it?
It provides an independent review based on fresh command results instead of relying on the implementer's assessment.

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

auto-verify 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 5d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

auto-verify

Verification gate. Independent audit of a completed plan. It runs once, not per-slice.

First action: run node .agent/.automaton/scripts/get-context.mjs from the project root.

Preamble

Independent audit. Re-read the plan, run proof commands, and compare fresh results to acceptance criteria. It does not trust execute's self-assessment or fix what it finds. When continuing inline from execute, re-derive from fresh command output; execute's reasoning is context, not evidence.

Loading discipline: on warm continuation from execute, one PLAN.md read plus verification commands per criterion. On cold entry, load in dependency order, spec before plan; auto-resume owns the full order table. Read source files when verifying correctness requires inspecting the actual changes, not just command output.

Quality Gate

Before writing the verification report:

  • Tie every result to fresh command output or direct observation.
  • Name skipped checks explicitly. Omission is not a pass.
  • Treat partial evidence as FAIL for the plan.
  • Read references/quality.md when the report sounds confident without proof.

Do

Load State

Read the canonical PLAN.md. Load only linked slices/slice-NNN.md files and referenced requirement IDs from spec/*.md: linked detail and traceability IDs are normative, and an unlinked supplemental file is not verification context. For prose slices, read references/content-verification.md.

Mark Verify Stage

After PLAN.md resolves and before running commands, run node .agent/.automaton/scripts/sync-status.mjs --stage verify from the project root.

Collect Acceptance Criteria

Gather every acceptance criterion and verification command from every slice in PLAN.md. Build a checklist: slice name → criterion → command. This is a plan-level audit.

Do NOT modify source code, tests, or project artifacts during verification. Verify reads and runs commands; its only writes are the markdown records this skill owns (VERIFY-GAP blocks, the ## Verification section, the ROADMAP phase update). It does not fix.

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.
