PRD Review

Dispatch parallel expert reviewer agents against a PRD to produce a scored analysis with prioritized gaps, severity tiers, and an enhanced PRD with suggested fixes.

Output Path — MANDATORY

All review output goes into a per-run, date-keyed folder under the feature's reviews/prd/ directory:

{output_dir}/{feature}/reviews/prd/{date}{_counter}/        ← {review_dir}
├── summary.md                              ← {review_summary}    (main output)
├── source-prd.md                           ← verbatim source snapshot (side-artifact)
├── enhanced-prd.md                         ← {review_enhanced}   (P0/P1 inline + P2 comments)
├── review-comments.json                    ← canonical structured per-section gaps (side-artifact)
└── detailed/
    ├── pm-reviewer.md                      ← {review_detailed} (agent=pm-reviewer)
    ├── agile-coach.md                      ← {review_detailed} (agent=agile-coach)
    ├── tech-lead-reviewer.md               ← {review_detailed} (agent=tech-lead-reviewer)
    ├── dx-reviewer.md                      ← {review_detailed} (agent=dx-reviewer)
    └── finops-analyst.md                   ← {review_detailed} (agent=finops-analyst)

{output_dir}/{feature}/outputs/reviews/prd/{date}{_counter}/  ← {review_outputs_dir}
├── summary.html                            ← {review_summary_html}
└── enhanced-prd.html                       ← {review_enhanced_html}

Where {output_dir} comes from .shield.json output_dir field (default docs/shield), {feature} is the feature folder ({feature-name}-YYYYMMDD), {date} is today's ISO date (YYYY-MM-DD), and {_counter} is empty for the first run of the day or _2, _3, ... on same-day collisions. Numbered-run subfolders (prd-review/{N}-{slug}/) are gone. Reviews never overwrite prior runs.

Resolving the counter: before writing, list {output_dir}/{feature}/reviews/prd/ for entries matching today's date. If {date}/ does not exist, use _counter="". Otherwise, find the highest {date}_<N>/ and use _counter="_<N+1>". Do NOT use any other path. The Write tool creates directories automatically.

When to Use

• User invokes /prd-review with a PRD source (file path, URL, or paste)
• User asks "review my PRD" / "what's wrong with this PRD" / "PRD gap analysis"

When NOT to Use

• Plan review (technical breakdown / stories) — use /plan-review instead
• Research review — use the research workflow's PM-review mode
• Code review — use /review

Step Skeleton

At startup, call execute-steps to register these steps. Execute them in order, updating status after each.

Workflow

1. Read context

• Read .shield.json for: output_dir (default docs/shield), prd_review_personas (default all 5), prd_ingest_resolvers (default [])
• Determine feature folder context: --feature <name> flag, or --name, or fall back to a prompt asking the user

2. Ingest

Follow ingest.md Steps 1-3:

• Classify input (local path / URL / paste)
• Route through resolver chain if URL
• Snapshot result to {review_dir}/source-prd.md (where {review_dir} = {output_dir}/{feature}/reviews/prd/{date}{_counter} resolved per the Output Path section above)

3. Type detection + confirmation

Follow ingest.md Step 4. Confirm with user. Note: PRD-type override is per-invocation, not configured.

4. Dispatch (parallel — mixed pattern)

Read dimensions.md for the 14-entry dispatch registry. Two dispatch patterns coexist:

• Skill-internal prompts (rows 1, 2, 3, 7, 8, 9, 10, 11, 12 — all PM dims): read the prompt file at prompts/<name>.md, then dispatch a general-purpose Agent with that prompt content + prd_path and prd_type inputs. The agent returns one dim-block JSON.
• Legacy persona dispatches (rows 4, 5+6, 13, anti-patterns): dispatch the named subagent via subagent_type: <agent-id> (e.g. shield:agile-coach, shield:architect, shield:finops-analyst, shield:dx-engineer) with the per-persona prompt skeleton kept inline below. shield:architect is dispatched ONCE and grades both dim 5 and dim 6 in its returned envelope.

Critical: dispatch all 13 unique invocations in a single response (parallel). Aggregating after waits.

Legacy-persona dispatch prompt skeleton (substitute per row):

You are reviewing a PRD in PRD-Review mode. Mode: Standalone.

**PRD source:** {source-prd.md path}
**PRD type:** {standard | lean — confirmed by user}
**Your assigned dimensions:** {list from dimensions.md row}

**Rubric:** Read `shield/skills/general/prd-review/rubric.md` for evaluation points per
dimension, severity model, and grade scale. Read `shield/skills/general/prd-review/scoring.md`
for the A-F → composite logic.

**Your job:**
1. Read the PRD at the path above.
2. For each of YOUR assigned dimensions, grade each evaluation point A-F (or N/A with
   reasoning, or informational for lean dims).
3. Aggregate to a per-dimension grade.
4. Identify gaps — for each non-A grade, write a one-sentence gap description.
5. For each gap, suggest a fix (one or two sentences) suitable for `enhanced-prd.md`
   annotation.

**Output format:** Return JSON in the per-persona envelope:

{
  "persona": "<your agent id>",
  "persona_grade": "A|B|C|D|F",
  "dimensions": [
    { "id": <int>, "name": "...", "grade": "A|B|C|D|F|N/A|informational", "na_reasoning": "...",
      "evaluation_points": [ {"id": "Na", "grade": "...", "severity": "...", "gap": "...", "suggestion": "..."} ] }
  ],
  "anti_patterns": [ {"name": "...", "evidence_line": 42, "evidence_quote": "..."} ]  // DX only
}

Special instructions per legacy persona (unchanged from the deprecated personas.md):

• Agile-coach (dim 4): apply AC1-AC12 framework including persona-goal coverage (consume shield:story-coverage skill) and archetypal-flow coverage.
• Tech-lead / architect (dims 5, 6): treat 5b/5e as Critical for any feature with user data, Important for purely internal infra. Grade dim 5 and dim 6 in one dispatch.
• DX (anti-patterns): primary output is the anti_patterns array; no numeric dim.
• Cost / finops-analyst (dim 13): N/A allowed for clearly internal-only features (e.g., internal-tool fixture) with reasoning.

5. Aggregate

Collect dim-blocks from all 13 dispatch results. Two envelope shapes coexist:

• Per-dim envelope (skill-internal prompts): the returned JSON IS the dim-block — use directly.
• Per-persona envelope (legacy personas): unwrap the dimensions[] array; each element is a dim-block. Also capture anti_patterns[] from the DX dispatch.

Group dim-blocks by their owning persona (per dimensions.md's "Owning persona" column). Then apply scoring.md:

• Per-dimension grade (already in each dim-block)
• Per-persona grade (compute by averaging the persona's dim-blocks numerically; for product-manager, this means averaging the 9 PM dim-blocks since the omnibus persona-grade is no longer emitted)
• Composite weighted average across activated personas
• Detect P0s (any Critical eval point graded D or F)
• Apply P0-gate to verdict

6. Generate enhanced-prd.md

For each gap-with-suggestion in the aggregated JSON:

• P0 or P1: insert inline in the relevant section of source-prd.md content; wrap with <!-- [from: <Persona>] --> attribution
• P2: insert as a comment block adjacent to the relevant section, prefixed <!-- Suggestion (<Persona>): ... -->
• Informational: insert as comment with <!-- [informational] --> tag

Preserve source-prd.md's exact structure; only ADD content, never replace.

Write the result to enhanced-prd.md.

7. Write output artifacts

7b. Render review HTML

Render summary.md and enhanced-prd.md into {review_outputs_dir} via the shared shell, then refresh the manifest-derived page assets:

"$CLAUDE_PLUGIN_ROOT/scripts/render-markdown.sh" \
  --md    {review_dir}/summary.md \
  --shell "$CLAUDE_PLUGIN_ROOT/templates/shell.html" \
  --out   {review_outputs_dir}/summary.html \
  --assets-root "{output_dir}" \
  --title "Review — {feature}"

"$CLAUDE_PLUGIN_ROOT/scripts/render-markdown.sh" \
  --md    {review_dir}/enhanced-prd.md \
  --shell "$CLAUDE_PLUGIN_ROOT/templates/shell.html" \
  --out   {review_outputs_dir}/enhanced-prd.html \
  --assets-root "{output_dir}" \
  --title "Review — {feature}"

uv run "$CLAUDE_PLUGIN_ROOT/scripts/write_shield_assets.py" --output-dir "{output_dir}"

Do NOT write per-skill *.shell.html files — the shared shell at $CLAUDE_PLUGIN_ROOT/templates/shell.html owns DOCTYPE/head/nav/footer.

8. Update manifest + dashboard

• Append a new entry to {output_dir}/manifest.json
• Regenerate {output_dir}/index.html to show the new review with verdict badge

9. Offer apply options

Emit to user (template):

PRD Review complete.

Verdict: <Ready | Needs Work (composite X.X, blocked by N P0s) | Not Ready>

Files written:
- summary.md       — scored analysis
- enhanced-prd.md  — your PRD with suggested fixes applied
- review-comments.json — machine-readable for converters
- detailed/<persona>.md — per-reviewer findings

What next?
1. **Use enhanced as canonical PRD** — copy `{review_enhanced}` to `{prd}` (i.e. `{output_dir}/{feature}/prd.md`) so downstream Shield commands consume the fixed version
2. **Convert back to original format** — produce `enhanced-prd.<ext>` in source's format (HTML / Notion-flavored markdown)
3. **Skip** — keep `{review_enhanced}` in `{review_dir}`; do nothing else

User picks; Shield executes.
