verify-built

verify-built is a skill for Claude Code, Codex from EZotoff/ez-omo-config. It costs 69 tokens per session (868 once invoked), scanned A, original, MIT.

An acceptance-check workflow that compares a software plan or specification with the implementation changes. It produces a list of gaps tied to a specific Git commit, which is a saved version of the code.

In plain words
What is it for?
Use it before accepting, submitting for review, or packaging implementation work to list requirements, compare them with the diff, and record unresolved gaps.
Why use it?
It helps reveal whether the delivered change matches what was requested before a handoff or pull request. The commit binding also shows when the check is no longer current because the code changed.

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

verify-built 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.

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.

Verify-built — alignment check (stage 1)

Triggers: /verify-built, "verify built", "alignment check", "did we build what we planned", "acceptance check"

The acceptance boundary (non-negotiable)

  • Your output is a pass record for humans to judge, never authorization to proceed. No merges, PRs, dispatches, or continuations on the strength of your ledger alone.
  • The ledger binds to an immutable digest. If the work changes after you run, the record is stale — anyone may discard it.
  • When you are the implementer of the very work being verified, say so in the record; the operator may then route verification to an independent agent (recommended for high-risk changes).

Workflow

1. Bind to a digest FIRST

Record repo / branch / HEAD sha / dirty|clean / timestamp before reading anything. If the tree is dirty, record the diff hash too (git diff | sha1sum). This header is what makes the record trustworthy-or-discardable.

2. Extract requirements

From the active plan (.omo/plans/*.md, task brief, or issue): every requirement, checkbox, and stated done-condition — as a numbered list, each phrased as a checkable statement. Include scope prohibitions ("must not change X") as requirements.

  • Executed-plan record check: if the plan shows signs of execution (any checked - [x] box), also extract record requirements — one Execution baseline: line and one F#<n>: verdict line per final-wave reviewer under ## Execution Record. Missing lines map to GAP ledger entries ("execution record missing: baseline" / "…: F# verdict") — flag them; never reconstruct or invent them.

3. Map to evidence

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.
