Every gap you miss becomes hours of wasted work downstream. Agents will execute this plan trusting your review caught the problems. That trust is earned by thoroughness, not speed. Your career-defining reviews prevent catastrophic integration failures before they happen.
You MUST:
- Compare plan to parent design document (if exists)
- Verify every interface between parallel work streams is explicitly specified
- Identify every point where executing agents would have to guess or invent
- Verify existing code behaviors cite source, not method name inference
An implementation plan that sounds organized but lacks interface contracts creates incompatible components.
Invariant Principles
Parallel agents hallucinate incompatible interfaces when contracts are implicit. Every handoff point must specify exact data shapes, protocols, error formats.
Assumed behavior causes debugging loops. Plans referencing existing code must cite source, not infer from method names. Parameters like
partial=Trueorstrict=Falseare fabricated until verified.Implementation plans must exceed design doc specificity. Design says "user endpoint"; impl plan specifies method, path, request/response schema, error codes, auth mechanism.
Test quality claims require verification. Passing tests prove nothing without auditing-green-mirage. Test failures require systematic-debugging, not ad-hoc fixes.
Inputs
| Input | Required | Description |
|---|---|---|
impl_plan |
Yes | Path to or content of the implementation plan to review |
design_doc |
No | Path to parent design document for comparison |
codebase_root |
No | Project root for verifying existing code behavior references |
Phase 1: Context and Inventory
Dispatch subagent with review-plan-inventory command. If command unavailable, execute phase criteria directly.
Establishes context: parent design doc comparison, work item counts, parallel vs sequential classification, setup/skeleton work requirements, interface inventory between parallel tracks.
Gate: Proceed only when inventory is complete and all work items are classified.
Phase 2: Interface Contract Audit
Dispatch subagent with review-plan-contracts command. If command unavailable, execute phase criteria directly.
Audits every interface between parallel work streams: request/response/error formats, type/schema contracts, event/message contracts, file/resource contracts.
Optional deep audit: For task descriptions with ambiguous language, run /sharpen-audit on the task text to get executor-prediction analysis (what an implementing agent would guess for each ambiguity).
Gate: Proceed only when every interface has been audited.
Phase 3: Behavior Verification Audit
Dispatch subagent with review-plan-behavior command. If command unavailable, execute phase criteria directly.
Verifies all references to existing code cite verified source behavior, not assumptions from method names. Flags fabrication anti-patterns, dangerous assumption patterns, and loop detection red flags.
Gate: Proceed only when every existing interface reference has been classified as VERIFIED or ASSUMED.
Phase 4-5: Completeness Checks and Escalation
Dispatch subagent with review-plan-completeness command. If command unavailable, execute phase criteria directly.
Verifies definition of done per work item, risk assessment per phase, QA checkpoints with skill integrations, agent responsibility matrix, and dependency graph. Escalates claims requiring fact-checking skill.
Gate: Proceed only when completeness audit is done and all escalation claims are cataloged.
Report Assembly
Assemble the final report from subagent outputs:
## Summary
- Parent design doc: EXISTS / NONE
- Work items: X total (Y parallel, Z sequential)
- Interfaces: A total, B fully specified, C MISSING (must be 100%)
- Behavior verifications: D verified, E assumed (assumed = CRITICAL)
- Claims escalated to fact-checking: F

Surface-Level Reviews
- "Plan looks well-organized"
- "Good level of detail"
- Accepting vague interface descriptions
- Skipping interface contract verification
Vague Feedback
- "Needs more interface detail"
- "Consider specifying contracts"
- Findings without exact locations
- Remediation without concrete specifications
Parallel Work Assumptions
- Assuming agents will "coordinate"
- Assuming interfaces are "obvious"
- Assuming data shapes can be "worked out"
Interface Behavior Fabrication
- Assuming method behavior from names without verification
- Referencing parameters that may not exist
- Claiming library behavior without citing documentation
- Assuming test utilities work "conveniently"
- Accepting "try X, if fails try Y" patterns
- Stopping before complete audit
[ ] Did I compare to parent design doc (if exists)? [ ] Did I verify impl plan has MORE detail than design doc? [ ] Did I classify every work item as parallel or sequential? [ ] Did I identify all setup/skeleton work? [ ] Did I inventory EVERY interface between parallel work? [ ] Did I verify each interface has complete contracts (request/response/error/protocol)? [ ] Did I verify Type/Schema contracts are complete? [ ] Did I verify Event/Message contracts are complete? [ ] Did I verify File/Resource contracts are complete? [ ] Did I verify existing interface behaviors cite source, not method name inference? [ ] Did I flag fabricated parameters and try-if-fail patterns? [ ] Did I identify claims requiring fact-checking escalation? [ ] Did I check definition of done for each work item? [ ] Did I verify risk assessment exists for each phase? [ ] Did I verify QA checkpoints exist with pass criteria? [ ] Did I check for auditing-green-mirage and systematic-debugging integration? [ ] Did I build the agent responsibility matrix? [ ] Did I verify dependency graph and check for circular dependencies? [ ] Does every finding include exact location? [ ] Does every finding include specific remediation? [ ] Did I separate Critical/Important/Minor findings? [ ] Did I provide prioritized remediation plan? [ ] Could parallel agents execute without guessing interfaces OR behaviors?
If NO to ANY item, go back and complete it.
The question is: "Could multiple agents execute this plan IN PARALLEL and produce COMPATIBLE, INTEGRABLE components?"
For EVERY interface between parallel work, ask: "Is this specified precisely enough that both sides will produce matching code?"
If you can't answer with confidence, it's under-specified. Find it. Flag it. Specify what's needed.
Parallel work without explicit contracts produces incompatible components. This is the primary failure mode. Hunt for it relentlessly.
