wiki-author

name	wiki-author
description	Update or create a Diátaxis wiki page for the current repo (or another registered repo). Triggers when the operator says 'update the wiki', 'document this in the wiki', 'add this to the wiki', 'create a wiki page for X', or 'update <repo>'s wiki'. Resolves target repo via cwd (default) or explicit repo name (cross-repo via repo_registry from V4 #30 plan 1). Dispatches crickets' wiki-maintenance:documenter sub-agent for the structural edit with preview-before-write, and defers to crickets' wiki-maintenance diataxis-author skill for mode selection — both graceful-skip if crickets' wiki-maintenance plugin is absent. Honors per-repo .diataxis-conventions.md override. Does NOT auto-generate content — agent gathers context from the conversation; the skill handles dispatch + write contract.

wiki-author — operator-facing dispatcher for wiki edits

Auto-fires on operator phrases like "update the wiki with what we just shipped" or "add this to the wiki". Resolves which Diátaxis mode page to update or create, then dispatches crickets' wiki-maintenance:documenter sub-agent (the write-executor, hard-boundary-scoped to wiki/** per ADR 0004 Amendment 2026-05-27) — graceful-skip if crickets' wiki-maintenance plugin is absent (this skill still resolves the target + builds the context bundle; only the write step is suggested-then-skipped, never hard-failed). Operator confirms every write via preview-before-write gate.

Triggers and non-triggers

This skill auto-activates on imperative wiki-write phrases. The trigger set is intentionally narrow to avoid false-positives in unrelated conversation.

Trigger phrases (5/5 expected to fire)

Phrase pattern	Resolution
"update the wiki" / "update the wiki for this repo"	cwd-relative; documenter picks the most-relevant page from the conversation diff
"document this in the wiki" / "add this to the wiki"	cwd-relative; mode picked from content kind (refactor → explanation; new command → reference; bugfix walkthrough → how-to)
"create a wiki page for X" / "add a wiki page about X"	cwd-relative; ask operator for mode if not derivable from X
"update {repo-slug}'s wiki" — explicit cross-repo	resolves target via python3 scripts/repo_registry.py list; writes to <root>/wiki/
"what's the latest in {repo-slug}'s wiki" — read-only query	redirects operator to /recent-wiki-changes --repo {slug} slash command (separate surface)

Non-triggers (5/5 expected NOT to fire)

Phrase	Why not
"the wiki page mentions..."	descriptive, not imperative
"I saw it on Wikipedia"	unrelated topic
"the wiki/ tree"	descriptive code reference
"wiki articles vs documentation"	discussion, not write request
"docs in wiki/explanation"	path reference, not a write request

If operator's phrasing is ambiguous (e.g. "add this somewhere"), do NOT fire — ask the operator to clarify or use an explicit phrase.

Resolution: cwd vs cross-repo

1. Default = cwd-relative. If operator says "update the wiki" from inside a registered repo, target is <cwd-root>/wiki/.
2. Explicit cross-repo via slug. If phrase names another slug ("update sherwood's wiki"), resolve via repo_registry.list_repos():

   python3 scripts/repo_registry.py list | python3 -c "
   import json, sys
   d = json.load(sys.stdin)
   for r in d.get('repos', []):
       if r.get('slug') == 'sherwood':
           print(r.get('root_path'))
           break
   "
   

3. Cwd outside any registered repo + no explicit slug. Refuse with actionable error:

   "Current directory isn't a registered repo. Register first: python3 scripts/repo_registry.py register <slug> --root <path>. Or specify the target: update {slug}'s wiki."

4. MEMORY_VAULT_PATH unset OR registry empty. Falls back to cwd-only mode. Cross-repo phrases refuse with: "Cross-repo writes need a vault-backed repo registry (V4 #30 plan 1). Run bash install.sh --scope user to set up, OR work in cwd."

Dispatch contract

After resolution, this skill ALWAYS:

1. Loads the per-repo .diataxis-conventions.md override if present in the target repo root. Operator-locked conventions take precedence over global defaults.
2. Loads the doc-write-time context bundle (V4 #35) for the resolved target repo:

   python3 scripts/harness_memory.py documenter-context --slug "<resolved-target-slug>" --format text
   

   <resolved-target-slug> is the cwd project's slug in cwd mode (python3 scripts/vault_project.py read .) or the explicitly-named slug in cross-repo mode. The bundle carries operator conventions to honor + project decisions to respect + locked design calls to NOT re-litigate. Graceful-skip: on rc 1 (vault unreachable) emit [wiki-author] vault unreachable; proceeding without vault context and continue with pre-v4.6.0 behavior. On rc 2 (target not registered) the bundle still carries operator-global _always-load/ conventions — use them. This routes through the same resolver the documenter sub-agent uses, so the operator's settled calls surface uniformly across both surfaces.
3. Determines Diátaxis mode for the write target:
   • Update existing page: preserves the page's existing mode (don't cross-mode mix; that fails check-wiki.py --strict).
   • Create new page: derives mode from the phrase ("how-to for X" → how-to dir; "reference for X" → reference dir); if ambiguous, asks the operator interactively. Defers to crickets' wiki-maintenance diataxis-author skill if available for richer mode selection (graceful-skip when crickets is not installed).
4. Drafts the structural edit + emits a unified diff preview to the operator before writing — and surfaces the step-2 context bundle alongside the diff so the operator sees here's what's locked + what we've decided before next to the proposed change. Per-write gate (every cross-repo edit gates on approval).
5. On operator approval: dispatches crickets' wiki-maintenance:documenter sub-agent with the resolved target + draft content. The documenter performs the actual file write under its hard-boundary scope (per the crickets wiki-maintenance:documenter spec) — graceful-skip if crickets' wiki-maintenance plugin is absent: the resolve + bundle steps still run, but the write is suggested-then-skipped rather than hard-failed.
6. Cross-references: ADR 0004 Amendment 2026-05-27 (preview-before-write + .diataxis-conventions override + repo_registry resolution); crickets' wiki-maintenance:documenter sub-agent spec (write-scope hard boundary + V4 #35 pre-flight; canonical since the seven-section convergence retired agentm's copy); crickets' wiki-maintenance diataxis-author skill (mode selection + per-repo conventions, when crickets is installed).

What this skill does NOT do

• Does NOT auto-generate content — the agent invoking this skill gathers context from the conversation (the diff just landed, the design call locked, the bug-fix narrative); the skill's job is dispatch + write contract, not content generation. Content generation is V5 / V6 territory.
• Does NOT write outside wiki/** — documenter's hard-boundary scope is wiki/** + a few specific files; this skill never relaxes that.
• Does NOT batch writes without per-write approval — even when multiple pages need updates from the same conversation, each cross-repo write gates on operator confirmation.
• Does NOT trigger on read-only wiki queries — those route to the /recent-wiki-changes slash command (added V4 #30 plan 2 task 7).

When NOT to invoke this skill

• Operator is reading the wiki (descriptive language, not imperative).
• Operator is asking about wiki structure or conventions (route to ADR 0004 / Diátaxis docs instead).
• Operator wants to write to a NON-wiki file (PLAN.md, progress.md, AGENTS.md, source code) — those are off-limits for documenter; refuse + route the operator to the appropriate surface (the harness /work phase, manual edit, etc.).

Per-host adapter

This skill is supported_hosts: [claude-code] for v0.1.0. The trigger semantics rely on Claude Code's skill-description matching; other hosts (e.g. Antigravity) would need their own trigger mechanism (slash commands, explicit invocation, etc.). Future versions may extend to supported_hosts: [claude-code, antigravity] once Antigravity's skill-triggering semantics stabilize.
