Spec Review Skill

Purpose

Run 3 focused review agents against a feature's spec files, then consolidate into an actionable PASS / NEEDS REVISION report.

Agents run sequentially by default. Run in parallel only if the user explicitly requests it.

Agent count by mode:

• Quick mode (plan.md only): 2 agents (skip Agent 3 — Buildability)
• Full mode (all 3 files present): 3 agents
• Partial Full mode (some files missing): 2 agents (skip Agent 3)

Activation Triggers

• "review the spec", "review feature spec", "check the spec"
• "is this spec good?", "validate the spec", "audit the spec"
• Before moving from planning to implementation
• /dev-workflow:spec review

Step 1 — Locate the Spec

1. List docx/features/ to find all feature directories
2. If a feature name was given as argument, match it
3. If ambiguous, show the list and ask which feature to review
4. If docx/features/ does not exist, stop: "No feature specs found. Run /dev-workflow:spec create first."
5. Identify which files exist and record their absolute paths — do NOT read contents into context. Agents read files themselves.
   • Quick mode: plan.md
   • Full mode: requirements.md, design.md, tasks.md (note which are present)
   • Set traceability_eligible = true only if all three Full mode files exist

Dispatch Prompt Template

Each agent prompt must be self-contained. Include:

1. Role: "You are reviewing a feature spec for [agent name]."
2. File paths: Absolute paths — tell the agent to read them with the Read tool. Do NOT paste content inline.
3. Checklist: The check items for that agent (from Step 2 below)
4. Output format: PASS or NEEDS REVISION, then labeled findings with severity icons

Step 2 — Run Review Agents

Default: sequential (1 → 2 → 3). Summarize each agent's findings in one line before the next.

Parallel: Only if user explicitly says "run in parallel" — emit all Agent tool calls in a single message.

Agent 1: Spec Quality

Covers: Business validity + EARS correctness + ambiguity smell scan

Prompt includes: absolute paths to all spec files

Business:

• Problem being solved clearly stated?
• Value / benefit to user or system explicit?
• Goals realistic and well-scoped?
• Gold-plated or out-of-scope requirements?
• Acceptance criteria meaningful?
• Unstated business assumptions?

EARS Correctness (Full mode):

• Every requirement uses proper EARS syntax (WHEN/THEN, WHILE, IF/THEN, WHERE, ubiquitous SHALL)
• Each requirement is one atomic statement (no compound AND)
• Active voice, SHALL for mandatory, SHOULD for desirable
• No contradicting requirements

Plan Correctness (Quick mode):

• Tasks unambiguous and actionable
• Clear done criteria per task

Ambiguity Smell Scan — flag every occurrence:

For each smell: cite requirement ID, name the smell, suggest a concrete rewrite.

Return: PASS or NEEDS REVISION + severity-labeled findings

Agent 2: Completeness

Covers: Missing scenarios + safety/liveness invariants + testability scoring

Prompt includes: absolute paths to all spec files

Completeness:

• Happy path covered?
• Error / failure scenarios?
• Edge cases: empty inputs, zero values, max bounds, concurrent access?
• Auth / permission requirements?
• NFRs: performance, security, scalability?
• Data validation rules?
• Rollback / undo behavior (if relevant)?
• All actors / user roles accounted for?
• Implied behaviors not written down?

Safety Invariants — what must NEVER be true?

• State: "shall never allow X while Y"
• Security: "unauthorized users shall never access Z"
• Data integrity: "balance shall never go negative"
• Concurrency: "two requests shall never simultaneously modify the same record"

Flag specs with async/stateful/multi-actor behavior that have no safety boundaries stated.

Liveness — what must EVENTUALLY happen?

• No infinite-wait guarantees
• Every pending request eventually gets a response or timeout
• Every queue eventually drains

Testability (0–3 per requirement):

For each 0 or 1: explain the blocker and suggest a rewrite that raises the score.

Return: PASS or NEEDS REVISION + missing scenarios + invariants + testability scorecard + avg score

Agent 3: Buildability

Covers: Compatibility + implementation blockers + traceability

Only dispatch when traceability_eligible = true (all 3 Full mode files present). Skip for Quick mode and partial Full mode.

Prompt includes: absolute paths to all spec files

Compatibility:

• Design aligns with existing tech stack?
• Breaking changes to existing interfaces?
• Dependencies available and versioned?
• External API contracts defined?
• Integration points with third-party services specified?
• Backward compatibility addressed?
• Rate limits, quotas, SLA constraints mentioned?
• Regulatory / compliance implications (GDPR, PCI, HIPAA)?

Implementation Blockers — flag anything that will immediately block a developer:

• Requirements that need an unresolved decision ("store user data" — where?)
• References to undefined systems, APIs, or services
• Contradicting requirements that make a single implementation impossible
• Missing technical definitions developers will ask about immediately

Traceability chain:

• REQ→Design: every requirement addressed by at least one design decision?
• Design→Tasks: every design element has at least one implementing task?
• Tasks→REQ: every task traces back to a requirement or design element?
• Acceptance criteria in requirements consistent with done-criteria in tasks?

If requirements have no REQ-XXX IDs, trace by text — don't fail silently.

Return: PASS or NEEDS REVISION + compatibility concerns + blockers (🔴) + traceability matrix (REQ | Design | Tasks | Status)

Step 3 — Consolidate

Wait for all agents to return before consolidating.

# Spec Review: [Feature Name]
**Mode:** Quick | Full | Partial Full  **Date:** [today]

## Verdict: PASS ✅ | NEEDS REVISION ❌

## 1. Spec Quality [PASS|NEEDS REVISION]
[business + correctness + smell findings]

## 2. Completeness [PASS|NEEDS REVISION]
[missing scenarios + invariants + testability scorecard + avg score]

## 3. Buildability [PASS|NEEDS REVISION|N/A]
[compatibility + blockers + traceability matrix]

## Action Items
| # | Sev | Agent | Issue | Fix |
|---|---|---|---|---|
...

## Summary
Critical: N  Warnings: N  Suggestions: N  Avg testability: X.X/3.0
→ [Proceed to implementation | Revise spec first]

Verdict Rules

• PASS — zero 🔴 Critical issues across all agents
• NEEDS REVISION — any 🔴 Critical issue blocks implementation
• Agent 3 is N/A for Quick mode or partial Full mode

If NEEDS REVISION: offer to open the spec file or activate spec-driven-planning to revise.
