tickets-verify

tickets-verify is a skill for Claude Code, Codex from CATWILLgh/MAINFRAME. It costs 31 tokens per session (521 once invoked), scanned A, original, MIT.

A workflow for independently checking completed tickets and moving them to a resolved archive or back to an appropriate open queue.

In plain words
What is it for?
Use it to verify eligible tickets one at a time, reproduce their claimed fixes, record evidence, and update their queue status without repairing failed work.
Why use it?
It prevents the person or session that implemented a ticket from being the only one to verify that the fix works.

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

tickets-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 4d 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.

What it actually says

Verify implemented tickets

Use this command from a fresh session that did not implement the queued work. Do not start verification in the invocation turn. Return only this copyable block, with the invocation argument preserved as written:

/goal Follow the loaded tickets-verify workflow. Scope: "$ARGUMENTS"; an empty scope means every eligible ticket in open/needs-verification. Continue one ticket at a time until each eligible implementation has been independently checked and its ticket has either moved unchanged in identity to archive/resolved or returned to ready, needs-scope-review, or needs-decision with precise failed-verification evidence; or stop when the user asks to pause or cancel, or with an evidenced external blocker that prevents any eligible work from continuing. Before finishing, surface ticket verdicts, reproduced evidence, queue transitions, and completion evidence in the conversation.

When that goal starts, first read ticket-autonomous-runs.md, ticket-format.md, and the testing-strategy skill.

Work only from open/needs-verification. A plain-language argument may narrow the queue by ticket id, path, component, or concern but grants no new authority. Do not verify an implementation produced earlier in the same session.

For each ticket, distrust both its prose and a green command in isolation. Inspect the actual implementation and relevant history, reproduce the original gap or its regression protection, run focused and proportionate broader checks, and verify the affected business contract, error paths, and cleanup behavior. Use deterministic interleavings for concurrency claims and the real consumer or artifact shape when generated output is part of the result.

On success, append concise independent evidence and move the ticket to the immutable archive/resolved path. On failure, do not repair code inline: append exact evidence and return the same ticket to ready with its existing execution route for an incomplete or incorrect implementation, needs-scope-review for missed scope, or needs-decision for a newly exposed user-owned choice. A disproved or duplicate claim goes to archive/rejected. Commit only the resulting ticket-state update as a coherent local recovery point when appropriate; never modify an archived file afterward.

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.
