QualifiedCProgramming: Skill for Claude Code

.agents/skills-en/verification-orchestrator/SKILL.md

verification-orchestrator is a skill for Claude Code, Codex from QinxiangCao/QualifiedCProgramming. It costs 58 tokens per session (588 once invoked), scanned A, original, MIT.

A controller procedure for managing a complete C verification run, from setup and annotation work through proof checks, merging, and final validation.

In plain words
What is it for?
Use it to run the full verification workflow, manage annotation and proof workers, collect specification gaps, merge approved changes, and perform the final check.
Why use it?
It coordinates several verification roles and preserves the required order of their work, reducing the risk of incomplete or conflicting results.

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

verification-orchestrator 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.

What it actually says

Verification Orchestrator

For main only. Read all four documents before executing a case:

On Windows, also read the Windows runtime rules. At final-check, read final-check/SKILL.md and its required workflow.

Main maps controller owners to actual agent targets and executes the returned structured invocations. Claim each owner action first, then send the claim response's handoff.prompt verbatim to that agent. Create only one annotation agent per run; send repairs and later annotation attempts to that same agent. Use an independent owner for each VC-checking attempt and each group's first claim; repairs of the same task retain its owner. Main executes controller actions for vc-proving preparation, dispatch, merge, and parent checks; there is no separate phase agent.

After an owner writes its terminal report and stops editing, main executes finalize-delivery. This command performs all acceptance checks for that role directly; a completed report alone is not acceptance. Derive the next step from current task facts. Continue until phase: done, wait while owners are running, and report an explicit blocker when no action can proceed.

Main does not edit annotations, plans, or proofs on an owner's behalf, or proactively read, summarize, or restate owner skills. Owners read their role knowledge from their own handoffs. This division controls context; acceptance depends on current files, reports, and actual checks, not accidental extra reading.

If a frozen user specification must change, the owner records the proposal and stops. Main pauses the run and asks the user to approve it. After explicit approval, resume the run, execute unfreeze for the current annotation round, and return the work to the same owner. An unfrozen model-written specification may be repaired within the current annotation attempt.

When the user requests pause or stop, execute cancel-action for the current action, or pause-run if its exact id is unavailable. Wait for running tools to clean up their processes, then stop advancing. Call resume-run only after the user explicitly requests resumption, then run step. Tasks and owners remain unchanged; actions are recomputed from current state.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
