vulyk: Command for Claude Code

.claude/commands/vulyk-review.md

vulyk-review is a command for Claude Code from Black-coffe/vulyk. It costs 14 tokens per session (1,748 once invoked), scanned A, original, MIT.

A merge-review command that looks for reasons a code change should not be merged. It checks whether the changes match the files and stories they were meant to affect, then runs separate review and acceptance checks.

In plain words
What is it for?
Use it as a final check on current changes or a branch before merging. It is for comparing the real diff with the planned work and checking both implementation quality and acceptance.
Why use it?
It helps catch bugs, out-of-scope edits, and changes that do not meet the planned requirements before merging. It also gives the reviewer the project notes needed to judge the change.

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

vulyk-review 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 2d 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 — 17 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run the merge gate on: "$ARGUMENTS" (default: current working tree changes against the base branch).

  1. Run the scope gate first - it costs nothing and it decides what to look at. For each story in scope: bash scripts/scope-check.sh <story-file>. It compares the story's ## Files block against the real diff and appends the numbers to memory/stats/scope.jsonl. Files it flags go into the review packet as the first thing lead-review reads: an out-of-scope file is either a story that was written wrong or a worker that went wide, and knowing which is worth more than any single bug found later. Report the two numbers to the human alongside the verdict.
  2. Assemble the review packet: the diff, the story/plan files it implements, and pointers to docs/wiki/ notes + ADRs for the touched modules.
  3. Dispatch lead-review with the packet - with model: <TOP_MODEL>, the alias the session brief announced (bash scripts/top-model.sh if it scrolled away); its frontmatter opus is the floor, the parameter is the plan-aware upgrade - and drone-acceptance in the same message - they are independent in INFORMATION - one sees everything, the other almost nothing - so they run concurrently and the blind gate costs only wall-clock it was going to spend anyway. They are not independent in machine resources, but only acceptance runs anything, so the pair is safe. Two acceptance gates at once are not: a suite that binds fixed ports hands the second one EADDRINUSE, which reads exactly like a defect in the code under test. If you are catching up on several specs, run their gates one at a time. lead-review gets everything. drone-acceptance gets five things and no more: the spec's brief.md, the repository, the run command (the plan's integration gate, or the project's ## Commands), the Client path row of the Profile when it is filled - the URL, CLI or browser runner through which a person reaches the software, because stage 04 is not only the suite: the gate walks the client's path the way a client would - and the statement of which configurations exist yet, so it does not judge the build against a deployment shape you have deferred and can name in ASSUMED CONFIG what it judged against. Prefer the ## Profile block's Configurations that exist today row in CLAUDE.md - it holds configuration and nothing else, so it cannot leak. Fall back to a milestone ledger only where no Profile block is filled, and then name the section, not the file: the rest of that file is the framework's own account of what it built, and handing over a whole plan.md invites the gate to read past the ledger into the status tables. Observed exactly once, disclosed by the drone itself, which then re-verified independently - the disclosure worked, and the dispatch that made it possible should not be repeated. It must never receive plan.md, a story, or an implementation note: not knowing what the hive believes it built is the entire reason its verdict carries information. For Tier 4 changes, also dispatch a SECOND reviewer instructed to attack the first one's likely blind spots (concurrency, security, data migration safety). Make it a different model - two copies of one model are blind in the same places, and adversarial framing does not fix that. The session brief names the pairing (scripts/top-model.sh --explain prints it as second reviewer): opus beside a Fable gate; beside an Opus gate, fable where the plan carries it inside its limits and sonnet where it would bill to credits. See docs/model-cascade.md for the cost and data-retention tradeoff.
  4. Record the acceptance verdict, whatever it is: bash scripts/acceptance-log.sh docs/specs/<slug> <ACCEPTED|REJECTED|CANNOT_RUN> "<one line>". It reads the story statuses itself and computes the only number no other gate can produce: every story done while the blind gate did not accept. That is the framework contradicting its own account of itself, and it goes to the human out loud, in this review, not quietly into a file. CANNOT_RUN is logged too - a gate that could not run is data; hiding it is how a gate becomes decoration. The record now carries the commit and a fingerprint of the pack it was given against, because a verdict is about the stories that existed when the drone ran - not about whatever the spec grows into afterwards.
  5. On BLOCK or REJECTED: convert every finding worth acting on - not only the criticals - into a fix story in the same spec directory and route back through /vulyk-build. An acceptance BROKEN line outranks a review minor: it is the human's own request failing, observed by running it. Do not hand-patch findings in the main session, whatever their size: fixes stay in the cascade (Law 5), each in its own story with its own commit. Cutting a repair story invalidates the acceptance verdict - the gate judged a pack that no longer exists - and the owner's check, where one exists: scripts/human-check.sh --check will say STALE, and it is right. Re-dispatch drone-acceptance and log again when the repair round closes; a verdict inherited across a changed pack is the drift number quietly lying, which is worse than no number at all.
  6. Before proposing a merge, prove the verdict still describes what ships: bash scripts/acceptance-log.sh --check docs/specs/<slug>. CURRENT means the accepted pack is the shipped pack. STALE means stories were added, removed or renamed after the gate ran - re-dispatch it rather than carrying the old verdict forward. NO VERDICT RECORDED means the blind gate never judged this spec at all, and saying so is part of the report.
  7. On PASS: present both verdicts and the full finding list - lead-review reports everything and ranks it; deciding what to act on is your job, not its. Say plainly when acceptance declined to run and what that leaves unchecked. Then stop for stage 05 - the owner looks, and nothing after it happens until they have. Hand them a check card short enough to act on: the branch (**Branch:** in plan.md), where to look (the Profile's Client path row - the URL and test login, the CLI, or how to bring the test version up), and one line per ask in brief.md saying what they should see - the drone's WORKS lines are the source, not the stories. Do not describe what was built; say where to click. When they answer, record their words, not yours: bash scripts/human-check.sh docs/specs/<slug> ACCEPTED|REJECTED "<what they said they saw>". Never run it before they have answered - a check recorded on the owner's behalf is the failure the stage exists to stop. Commit the record on the spec branch (vulyk(<slug>): owner's check): a commit that touches only the cycle's own ledgers is paperwork and does not stale the check; a commit that touches code does, and human-check.sh --check tells the two apart. REJECTED goes the same road as a BLOCK: every named thing becomes a fix story, back through /vulyk-build, and both gates run again before the next look - any commit after the look makes the check stale, and human-check.sh --check says so. ACCEPTED hands over to /vulyk-ship: history, version, the merge, the map and wiki refresh and the ADR harvest all live there, after the human, not before.
