Decide

/orient:decide

Record one architectural decision as a numbered, append-only ADR.

Resolve the docs directory from CLAUDE_PLUGIN_OPTION_DOCS_DIR (default docs).

1. Find the highest existing ADR number in <docs_dir>/decisions/ and add one. Filenames are NNNN-kebab-title.md, numbered from 0001.
2. Fill templates/adr.md. Interview the user only for what can't be inferred from the session — the alternatives that were considered and the trade-off accepted are the parts worth asking about. Infer the rest.
3. Show the drafted ADR and write it on approval.

Supersede rule: if this decision supersedes an earlier ADR, set Supersedes: in the new file and update only the Superseded by: line of the old one. No other edit to a past ADR is permitted — decisions are append-only.

Keep architecture and the shape diagram in sync

After the ADR is written, check whether this decision changes structure — entry points, module boundaries, or critical paths. If so, update two things, each shown as a before/after preview and written only after a separate approval (the user can accept the ADR but decline these):

• <docs_dir>/architecture.md — touch only the affected lines, refresh the updated: marker.
• the ## Shape mermaid diagram in <docs_dir>/STATE.md — only if the decision adds, removes, or reconnects a major component. Keep it to 6 nodes.

Skip whichever target doesn't exist, and skip the whole step for a non-structural decision.
