vulyk: Command for Claude Code

.claude/commands/vulyk-bootstrap.md

vulyk-bootstrap is a command for Claude Code from Black-coffe/vulyk. It costs 19 tokens per session (1,302 once invoked), scanned A, original, MIT.

A coding agent that creates or repairs tests for one planned story. Tests check observable behavior through the program's normal interfaces, including invalid input and other failure cases when required.

In plain words
What is it for?
Use it after implementation or on an under-tested area described by a story. It is for adding behavior tests, covering important edge cases, and fixing test failures caused by the work.
Why use it?
It turns the story's acceptance rules into checks and helps prevent regressions, which are old behaviors accidentally broken by new code. It also checks the wider relevant test suite.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is Black-coffe/vulyk's own configuration. It tells Claude Code how to work on vulyk itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vulyk configures →

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-bootstrap 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 3d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are initializing VULYK for this repository. Follow bootstrap/interview.md. The constitution is CLAUDE.vulyk.md if it exists, else CLAUDE.md. Nobody has to know this command: while the Profile still holds a <fill in row, the SessionStart brief tells the Queen to offer it once, before the first task. A no is recorded as the Profile row | Bootstrap | declined <date> |, which silences the offer.

  1. Interview. Ask the script's questions in three batches (context, conventions, posture). With --quick in "$ARGUMENTS", infer the answers from the repo (package files, CI config, lockfiles, README) and present them for one confirmation instead.
  2. Tailor the constitution.
    • Profile: fill the rows between the VULYK:PROFILE markers from what you verified in step 1, never from what a README claims; a profile copied from another repository is a confident lie. The row that pays for itself is Configurations that exist today, with what is deferred and until when: a reviewer that does not know it demands guarantees for deployments nobody has. Client path is how a person reaches the running thing (a URL and a test login, a CLI entry point, a browser runner's quiet command), or none: library only; a filled row adds the black-box seat at Tier 3-4. Release / deploy names the default branch, how a version is published and who presses the button; /vulyk-ship prints it and never presses it. Owner language is the one reports and questions to the owner come in (--quick: the language the owner writes in), en when unsure.
    • Top model: run bash scripts/top-model.sh --explain, show the owner what the plan resolved to and why, and leave TOP_MODEL = auto unless question 15 asked for a deliberate pin (then write the alias in its place). Then run bash scripts/top-model.sh --apply whatever the answer: it pins the Queen's own session in the gitignored .claude/settings.local.json, so the session runs on the model the ladder assumes rather than the account default.
    • Telemetry: do not ask; the installer did. Print bash scripts/telemetry.sh consent in the summary with the one line that changes it (install.sh --telemetry ask, or edit the | Telemetry | row).
    • Commands: replace every row between the VULYK:COMMANDS markers, and the warning blockquote above the table; the shipped rows are VULYK's own and wrong for any other project. Use this project's real commands in their quiet form (--reporter=dot, -q, --silent), because their output is resent on every later turn. Run each one; where the project lacks one (no build step, no test runner), write that instead of a plausible command, since a verification that always exits 0 is worse than an admitted gap. Per-story rows run in a minute or two. Name the full suite in its own row with (round-only) in its Purpose cell: the reviewer runs it once per round and no story names it. A suite that runs longer gets a part switch (--part <topic> or the runner's equivalent), and each story names the part covering its ## Files.
    • Court setup: question 7's install step goes verbatim into .claude/vulyk-setup (a bash script; it runs with the court as its working directory and VULYK_ROOT, VULYK_COURT set, capped at 300 s). Run it once in a scratch checkout before committing it. "None" writes no file. The installer never ships or touches this file (docs/cycle.md, stage 05).
    • Conventions tied to paths go into .claude/rules/<area>.md with a paths: frontmatter list (shape: templates/rule-example.md), not into the constitution, which every agent that loads it pays for on every turn.
  3. Prune the roster. Delete agents that cannot apply here (for example worker-test without a test runner, and say so in the summary) and adjust tool lists to the stack. The council seats are the ones whose removal is never silent: if this project cannot be run and observed at all (no Client path, no run command), write that sentence into the summary. Leave Browser MCP at none unless a browser-reachable Client path exists and the owner wants the black-box seat driving it on a separate test profile.
  4. Build the map. Identify the top-level modules and dispatch drone-scout per module, up to four in parallel; save each report as memory/map/<module>.md with a last-verified date, under ~80 lines. For 1000+ files, map breadth-first: the 8-12 most load-bearing modules now, the rest listed in memory/memory.md as unmapped.
  5. Seed memory. Write the memory/memory.md pointer index (at most 60 lines): map files, wiki notes to create, verification commands, unmapped territory.
  6. Seed the wiki: 2-4 docs/wiki/ notes for the most load-bearing domains or invariants found while mapping (templates/wiki-note.md).
  7. Commit everything as vulyk: initialize hive for <project> and print a summary: tier examples for this codebase, the plan-build-ship loop, and any pruned agents.
