Assess a spec task or delivery claim against its contract and available verification evidence.

What it does

Cy Final Verify is an agent skill from compozy/compozy. Assess a spec task or delivery claim against its contract and available verification evidence.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/conditional-contracts.md` and `references/pr-delivery.md`).

The repository describes itself as: An operating system for AI agents. Plug in the agent CLIs you already use (Claude Code, Codex, Gemini CLI, Cursor) and they become a team: they split the work, hand tasks to each… The licence is MIT.

Example prompts

  • “/cy-final-verify”

What it can do on your machine

Read from SKILL.md and the folder at commit eec2ed1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cy Final Verify loads about 561 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 28 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~561
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Assess a spec task or delivery claim against its contract and available verification evidence.

Verify the Requested Result

Identify the requested outcome, verification boundary, and remaining obligations. Use this inside the caller's existing validation step; it does not start another implementation, review, test, or QA cycle or authorize publishing.

Compare the result with the accepted contract and user goal, using already-grounded canonical examples and acceptance criteria. Pick the cheapest owning suite, probe, or artifact check that can expose a missing or failed behavior. Inspect the actual result and exit status. Reuse evidence while its source, dependencies, build/config, and environment remain applicable; a new message, handoff, or commit alone does not invalidate it. An unchanged HEAD does not prove a dirty tree was checked.

Repository delivery policy owns gates: in Compozy, make gate uses the affected lanes and fingerprint cache before commit/push; required CI at the current head owns PR delivery, and make gate-full is opt-in. A focused result supports its focused claim. A loop checkpoint names pending integration/visual checks and their owner without claiming they ran; the workflow resolves them before final delivery.

Read only the applicable reference when its details are needed:

  • Conditional contracts: the matching bug, spec, user-visible QA, named visual reference, or created-lab section.
  • PR delivery: when commit/push/PR delivery is requested and the caller does not already own that procedure.

Finish when the requested result and applicable checks are satisfied. Repair failures at their source and repeat only invalidated checks; preserve valid tests and warning/error policy. Continue authorized repairs without a review pause after the first implementation. Report a concrete blocker when a missing external input prevents completion.

Summarize the outcome, evidence, and material limits in the caller's existing report. Link larger artifacts when needed; do not create another checklist/report or broaden validation solely because a companion skill is installed.
