vulyk: Command for Claude Code

.claude/commands/vulyk-gc.md

vulyk-gc is a command for Claude Code from Black-coffe/vulyk. It costs 14 tokens per session (170 once invoked), scanned A, original, MIT.

A memory-maintenance command for a VULYK project. It asks a librarian agent to combine useful learnings, identify outdated project maps, remove old snapshots, and check the memory index.

In plain words
What is it for?
Use it periodically to clean and consolidate the project's memory directory. It is for maintaining learnings, maps, snapshots, and pointers used by later coding sessions.
Why use it?
It keeps stored project knowledge current and reduces clutter from stale or expired information. It also surfaces items that require a human decision.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter.

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-gc 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 8d 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

Dispatch librarian for a full GC pass over memory/ per its protocol (consolidate learnings, flag stale maps, prune snapshots >14 days, verify the pointer index).

Then act on its report in the main session:

  • Stale maps -> offer to run /vulyk-map for the flagged modules now.
  • "Needs human decision" items -> present them as a short list, decide nothing unilaterally.
  • If memory/learnings/CONSOLIDATED.md exceeded its 40-entry cap, note that the next /vulyk-evolve should promote the oldest stable entries into rules or wiki notes (learnings are a buffer, not an archive).
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.
