apply

apply is a skill for Claude Code from clomia/claude-automata. It costs 13 tokens per session (435 once invoked), scanned A, original, Apache-2.0.

A command for implementing a planned OpenSpec change task by task, then judging the result. It checks that required planning documents exist and asks an independent verifier to review observable behavior.

In plain words
What is it for?
Use it to apply OpenSpec tasks in dependency order, update the specification when necessary, and verify the finished implementation.
Why use it?
It keeps implementation tied to the approved requirements and prompts a fresh verification after the work is complete.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

apply 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

절차

  1. Judge the gate: every artifact listed in applyRequires must be done. (isComplete is not the gate; design exists only when its inclusion criteria apply.) Otherwise what is missing is planning, not implementation: return to tx:plan.

    "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" openspec status --change <change-id> --json
    
  2. Take the context file paths and the task checklist:

    "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" openspec instructions apply --change <change-id> --json
    
  3. Implement the tasks in dependency order. The spec wording binds the implementation. If implementation reveals the spec is wrong, fix the delta through tx:plan, then continue.

  4. When every task is done, judge the implementation. The verify stage judges every delta that moved observable behavior, on the change-id alone:

    Agent(subagent_type="tx:verify", prompt="change-id: <change-id>")
    

    A verify report is observation, not instruction. Before fixing a defect, generalize it: hunt the same cause on other surfaces and fix them together, and read the flow of reports to preempt the next one. Then respawn here until a pass is newer than the last behavior change. A defect that does not reproduce is a defect in the spec wording; a defect re-reported after a grounded rebuttal means the wording admits two readings — either way, fix the wording through tx:plan.

Unknown 처리

Every unknown met while implementing resolves one of three ways:

  • measurable: measure it and record the result.
  • reversible: adopt an assumption and state it in design.
  • neither: halt the task and record why in tasks.md.

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.

apply is a skill published in the GitHub repository clomia/claude-automata (13 stars, last pushed 5d ago), licensed Apache-2.0. It adds 13 tokens to every session and 435 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
