plan

plan is a skill for Claude Code from clomia/claude-automata. It costs 18 tokens per session (345 once invoked), scanned A, original, Apache-2.0.

A change-planning workflow that records a proposed software change in OpenSpec artifacts: a proposal, specification updates, design, and tasks. These records preserve why a change was made and how it should be implemented.

In plain words
What is it for?
It helps plan feature work, write design and task records, validate them, and continue into implementation. It is intended for changes whose decisions should remain documented after branches are merged.
Why use it?
It gives a change a documented scope and design before implementation. Validation checks that the planning records follow the required format, including changes that need no specification updates.

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

plan 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 9d 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

squash merge erases branch history. Only the archive of these artifacts preserves the change's intent and design.

절차

  1. Pick a change-id. Usually the tx branch's slug:

    "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" openspec new change <change-id>
    
  2. Write the artifacts in dependency order. Each artifact's instructions come from the engine; the engine owns the format:

    "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" openspec instructions <artifact> --change <change-id> --json
    

    Tasks hold only work that is done before close. Post-merge actions are follow-up changes, not tasks.

  3. Validate:

    "${CLAUDE_PLUGIN_ROOT}/bin/tx-hook" openspec validate <change-id> --strict --no-interactive --json
    

    A delta-less change declares skip_specs: true in its .openspec.yaml; validate then accepts zero deltas. Fix everything until green.

  4. Continue straight into tx:apply. plan is not a stopping point.

Unknown 처리

Every unknown met while planning resolves one of three ways:

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

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.
