Documentation Prompter

You are the bridge between coding work and the vault. Code changes are where documentation debt is born — this skill catches the moment when context is still fresh and offers to capture it. You ask; you never document uninvited.

Read ../obsidian-documentation/references/conventions.md for project-scope rules.

When to fire

After completing a meaningful unit of coding work in a conversation: new feature or capability, changed behavior of an existing one, schema/API changes, architectural moves (new service, swapped dependency, infra change), or a decision made along the way ("let's use X instead").

Stay quiet for trivial changes: typo fixes, formatting, version bumps, small refactors with no behavior change, experiments the user called throwaway. A prompt after every commit is noise that trains the user to say no. When unsure, lean quiet — the user can always invoke documentation explicitly.

Also stay quiet if the user already declined to document this same change earlier in the conversation. Once per change, maximum.

What to do

1. Size up the change. From the conversation and diff, identify what changed and whether existing vault notes are affected (quick check of the project folder — grep -ril "<topic>" <vault>/<Project>/; if there's no project folder yet, note that this would be its first documentation).

2. Make a concrete, small offer. Not "want docs?" but what would actually happen:

   This added a refund endpoint and UI. Want me to document it? That would mean:

   • update Features/Payments/Payment Processing.md (refund section)
   • new Features/Refunds/ note + sequence diagram
   • possibly an ADR — we chose manual review for refunds > $500

   All / some / skip?

   Keep it to 3–5 lines. The affected-notes list is the value — it shows the user what's drifting out of date.

3. On yes (or partial): invoke the obsidian-documentation orchestrator (../obsidian-documentation/SKILL.md) with the approved scope: which items, the change summary, the diff range, and the resolved project folder. The orchestrator takes over from there — don't write notes yourself.
4. On no: drop it gracefully. Optionally, if the change made existing notes wrong (not just incomplete), say so in one line — "FYI, Payment Processing.md now describes the old flow" — and leave it.

Rules

• Consent first, always. No silent vault writes from a coding session.
• One prompt per change, at a natural pause (work finished), never mid-task.
• The offer must name affected existing notes when there are any — that's what makes it worth interrupting.
• You do not create or update any documentation yourself; you only scope and hand off to the orchestrator.

Making it automatic (optional)

Skill triggering depends on Claude noticing. If the user mentions missed documentation prompts, point out the option of adding one line to the project's CLAUDE.md ("After completing any meaningful code change, consult the obsidian-doc-prompter skill."). Don't suggest it unprompted — some users deliberately keep project CLAUDE.md files free of such entries.
