LLM Wiki PRD

Sub-skill of llm-wiki-pm. Generates PM artifacts (PRDs, user stories, release notes) from wiki knowledge. The wiki is the only source of truth. Never fabricates product context.

When This Skill Activates

• "write a PRD", "draft PRD for [feature/topic]"
• "create user stories", "write user stories for [feature]", "acceptance criteria"
• "generate release notes", "draft release notes", "what shipped"

Does not activate for wiki operations (ingest, update, lint, query). Those route to llm-wiki-pm.

Orient Before Any Artifact

Per AGENTS.md, orient before any write. PRD generation requires knowing what pages exist to avoid duplication and ensure grounding.

Orient steps (mandatory):

WIKI=$(cat .wiki-path 2>/dev/null | tr -d '[:space:]')
WIKI=${WIKI:-${CLAUDE_PLUGIN_OPTION_wiki_path:-${WIKI_PATH:-$(pwd)}}}

① Read $WIKI/SCHEMA.md — tag taxonomy, domain scope ② Read $WIKI/index.md — what pages exist (prevents duplicate artifacts, identifies grounding material) ③ Read last 20-30 lines of $WIKI/log.md — recent activity ④ Read $WIKI/overview.md — current synthesis state

Orient gate (enforced): if steps ①-④ are not complete in this session, refuse any write. Surface: "Need to orient first. Running now." Then orient, then proceed.

Key Constraint

Never invent product context. If the wiki has no page for a claimed feature, customer segment, or competitive context, say so and offer to create a stub first:

"No wiki page found for [X]. Draft with that gap flagged, or create a stub page first?"

Every factual claim in a generated artifact must cite [[page]] from the wiki. No citation = no claim.

Operations

Output structures for all three operations live in references/prd-templates.md — copy the matching template when drafting.

1. PRD Draft

Trigger: "write a PRD", "draft PRD for [feature/topic]"

① Ground in wiki — grep -ri "<feature>" "$WIKI" --include="*.md" -l, then read every relevant page: entities, concepts, comparisons, customer pages, and decision/roadmap/question-tagged pages. ② Surface gaps before drafting — if a major section has no wiki backing (target persona, competitive context, core problem, key decisions), flag it and ask; never draft a fabricated section silently:

"Missing wiki coverage for: [X, Y, Z]. Draft with gaps flagged, or research first?"

③ Draft to $WIKI/queries/prd-<feature-slug>-<YYYY-MM-DD>/README.md using the PRD template (references/prd-templates.md). ④ Cite inline — every factual claim cites its source ("Per [[page]]..."); an uncited claim moves to Open Questions or gaps:. ⑤ Populate `gaps:` with unbacked sections — this surfaces in Coverage Audit. ⑥ Update navigation — add to index.md under queries/, append the prd log line.

2. User Stories

Trigger: "create user stories", "write user stories for [feature]", "acceptance criteria"

① Ground in wiki — same search as PRD ①. ② Read persona pages — grep -ri "persona" "$WIKI/entities" -l; read each relevant entities/<name>-persona.md for "As a [persona]" framing. If none exist:

"No customer entity pages found. Stories will use generic personas. Create customer pages first for grounded framing?"

③ Generate stories — As a [persona], I want [action] so that [outcome]. One per distinct need, grouped by persona. ④ Add acceptance criteria — Given/When/Then per story; flag any criterion that's an assumption with no wiki backing. ⑤ File to $WIKI/queries/user-stories-<feature-slug>-<YYYY-MM-DD>.md using the template; append the user-stories log line. ⑥ Link back from the relevant concept/roadmap page.

3. Release Notes

Trigger: "generate release notes", "draft release notes", "what shipped"

① Date range — if unspecified, ask; "last release" → find the prior release-notes entry in log.md for the cutoff. ② Read `log.md` for the range — filter for roadmap pages, decision entries, supersedes: changes (deprecations), and crystallize/PRD query entries. ③ Read the actual pages — log summaries are thin; pull substance from the pages, never write release notes from log lines alone. ④ Draft by category using the template. User-facing copy stays clean — no wiki jargon or [[wikilinks]]; citations go only in the internal-context section. ⑤ File to $WIKI/queries/release-notes-<YYYY-MM-DD>.md; append the release-notes log line.

Output Filing Conventions

All artifacts:

• type: query in frontmatter
• sources: lists all wiki pages consulted
• gaps: lists sections with no wiki backing
• Added to index.md under the queries/ section
• Logged in log.md

Behavioral Constraints

Inherited from AGENTS.md. The following apply specifically to artifact generation:

No fabrication. Every claim must cite a wiki page. If no page exists, the claim goes to gaps or open questions.

No silent gaps. If a major PRD section has no wiki backing, surface it before drafting and populate gaps: in frontmatter.

Orient first. Read SCHEMA.md, index.md, log.md tail, overview.md before generating any artifact.

No wiki jargon in user-facing copy. Release notes and PRDs shared externally should read naturally. Internal citations go in frontmatter sources: and an internal-only section.

No orphan artifacts. After filing, add the artifact to index.md and link back from any relevant concept or roadmap page it references.

Verify writes. Re-read after writing. If frontmatter is malformed, do not update index.md or log.md.

Pitfalls

• Grounding first, drafting second. Resist the pull to draft immediately. The grep + page reads are not optional.
• Gaps are information. A PRD with explicit gaps is more useful than one with confident fabrications.
• Log summaries lie by omission. For release notes, read the actual pages — not just the log lines.
• Persona pages are pre-work. Without entities/<name>-persona.md pages, user stories default to generic framing.
• Release note scope creep. Only include items with wiki backing. Don't pad from memory.
