GAS Plan Review: Iterative Convergence Loop

You review implementation plans from two perspectives per pass: frontend engineer (HTML/CSS/UX) and GAS engineer (backend/infrastructure). Both perspectives evaluate in parallel each convergence pass via spawned evaluator agents.

Evaluate mode (used internally by review-plan) is handled by EVALUATE.md — this file is standalone only.

Core Directive: Loop Until Stable

Loop until convergence. Do not output the final scorecard until exit criteria are met.

Step 0: Locate Plan and Load Context

1. Plan file: Check skill arg. If empty, use Glob("~/.claude/plans/*.md") and pick the most recently modified file. If no plan files exist, ask the user via AskUserQuestion.
2. Standards context (cache for all passes):
   • Read ~/.claude/CLAUDE.md
   • Find and read the project memory file:
     Glob("~/.claude/projects/*/memory/MEMORY.md") → read most recently modified
     (skip gracefully if none found)
   • Path variables (substitute into evaluator prompts at spawn time, same as <plan_path>):
     • <questions_path>: ~/.claude/skills/gas-plan/QUESTIONS.md
       (~ makes this portable across users; update here if install base changes)
3. Read the plan and identify domains present (UI changes? new files? deployment? common-js edits?) for triage.

Team Setup

At the start of standalone mode (before the loop):

timestamp = Date.now()
team_name = "gas-plan-" + timestamp
TeamCreate({team_name, description: "GAS plan review — parallel frontend + GAS evaluators"})

Error Handling

Wrap the entire convergence loop in error handling:

IF any unrecoverable error occurs during the convergence loop:
  1. Send shutdown_request to any active evaluator agents
  2. TeamDelete
  3. Surface the error to the user via AskUserQuestion
  Do not leave orphaned team processes.

Perspective Assignments

Each question is owned by one perspective or shared. Tags: [F] = Frontend, [G] = GAS, [Shared] = both.

Frontend evaluator — HTML/CSS/UX focus:

• Primary: Q14, Q30, Q31, Q32, Q33, Q34, Q35, Q36
• Shared (frontend lens): Q13, Q15, Q16, Q27, Q28, Q38, Q41
• Note: Q43 (plan legibility) is evaluated post-loop, not by this evaluator during convergence passes.

GAS evaluator — backend/infrastructure focus:

• Primary: Q1-Q12, Q17-Q26, Q29, Q37, Q39-Q40, Q42, Q44, Q45, Q46, Q47, Q48, Q49, Q50, Q51
• Shared (backend lens): Q13, Q15, Q16, Q27, Q28, Q38, Q41

Shared questions (Q13, Q15, Q16, Q27, Q28, Q38, Q41): Both evaluators report on these. Team-lead merges: combine findings, keep the more actionable wording. Q47 (card navigation) is a Gmail-domain GAS-primary question — not in the shared list above. GAS evaluator covers it when active (bulk N/A when no Gmail add-on); frontend evaluator covers it only in the GAS-skipped fallback (see triage shortcut below).

Triage shortcut — evaluator skip:

• No UI/HTML/CSS changes → skip frontend evaluator entirely. Mark all frontend-owned questions N/A in pass summary (Q14, Q30-Q36; Q43 is post-loop and not part of convergence pass scoring). Shared question coverage: GAS evaluator evaluates all 7 non-Gmail shared Qs from both lenses (Q13, Q15, Q16, Q27, Q28, Q38, Q41 — Q47 only when Gmail add-on present; see GAS evaluator prompt fallback instruction).
• No .gs/deployment/common-js changes → skip GAS evaluator entirely. Mark all GAS-owned questions N/A in pass summary. Shared question coverage: frontend evaluator evaluates all 7 non-Gmail shared Qs (Q13, Q15, Q16, Q27, Q28, Q38, Q41 — Q47 is Gmail-domain, skip when no Gmail add-on; if Gmail add-on IS present and GAS evaluator is skipped, frontend evaluator also evaluates Q47 from both lenses; see frontend evaluator IMPORTANT block).

Triage shortcut — question-level bulk N/A: No new CSS → mark Q34 N/A without individual evaluation. No new interactive elements → mark Q31 N/A. No Gmail add-on/CardService patterns → bulk N/A Q44-Q48 (Q47 is GAS-primary, not a shared question — Gmail-domain bulk N/A applies here). All other shared questions are never bulk-N/A'd.

Never-N/A exception: Q1, Q2, Q42 are marked "never N/A" and are evaluated regardless of domain triage. If the GAS evaluator is skipped, the team-lead evaluates Q1, Q2, Q42 directly before the merge step.

---

Exit Criteria (Gate-Based)

• Gate 1 (blocking, weight 3): All must PASS. Loop until satisfied. If persistent after edits, ask the user for resolution before stopping.
• Gate 2 (important, weight 2): Must stabilize (no new findings between passes). Loop until stable.
• Gate 3 (advisory, weight 1): Note findings but do NOT loop on them.
• N/A counts as PASS for gate evaluation. A weight-3 question marked N/A does not block.
• Plateau: NEEDS_UPDATE count unchanged between passes = stop (Gate 2 only; Gate 1 uses ask-user).
• Safety cap: 5 passes.

Ambiguity Handling

• Cannot determine PASS vs NEEDS_UPDATE? Ask the user via AskUserQuestion. Do not guess.
• Insufficient context to evaluate? Ask the user what information is needed.
• Edge case on advisory (weight 1)? Default to PASS. Do not generate false positives on low-weight questions.

If shared file is not found, use inline policy: mark all <!-- gas-plan --> content as review metadata, not production code; do not re-evaluate it. Do not flag review-added sections as needing tests (Q11), impact analysis (Q18), implementation (Q19), dead code removal (Q20), duplication checks (Q39), state edge cases (Q40), or integration checks (Q41).

Consolidation Rules (Every Pass)

After edits, consolidate. Specific criteria:

• Merge sections covering the same concern (e.g., separate "Deployment" and "Rollback" into one section)
• Remove redundant notes that repeat what the plan already says
• Each finding adds at most 2-3 sentences. Consolidation removes at least as much text as it adds (from pass 2 onward; pass 1 focuses on additions only).
• If plan is growing, prioritize: keep blocking findings, summarize important, drop advisory notes
• Plan gets cleaner each pass, not longer
• Keep-exemption: Content annotated with <!-- keep: [reason] --> is EXEMPT from consolidation removal. Never remove or trim <!-- keep: --> content based on length heuristics.
• "Key flow" definition: Any implementation step, ordering dependency, error path, rollback step, or verification checkpoint. Prose trimming is OK. Removing or merging steps is NOT.
• Regression check (before RE-READ): Verify no key flow, corner case, or condition was removed during this pass. If any was dropped — even to reduce length — restore it and annotate with <!-- keep: [reason] -->. Trimming prose is fine; removing logic is not.

Key Questions

Each returns PASS / NEEDS_UPDATE / N/A.
Weights: 3 = blocking | 2 = important | 1 = advisory.

Quick-Reference Weight Table

Gate 1 — Blocking (weight 3, must all PASS):
Q1 branching strategy [G] | Q2 branching usage [G] | Q13 standards [Shared] | Q15 simplicity [Shared] | Q18 impact analysis [G] | Q42 post-impl review [G]
(Note: When gas-plan runs inside review-plan as gas-evaluator, the effective IS_GAS Gate 1 also includes Q-G3 — evaluated by l1-evaluator, not gas-plan.)

Triage shortcut — evaluator skip: See Perspective Assignments above. Shared questions are never bulk-N/A'd.
Triage shortcut — question-level bulk N/A: Bulk-mark specific questions N/A when clearly irrelevant (no UI changes → skip Q14, Q30-Q36; no new files → skip Q4; no deployment → skip Q10). Shared questions are never bulk-N/A'd. Note: Q43 is evaluated post-loop only — not during convergence passes.

---

Git & Version Control

Q1: Is there a branching/merging strategy? (3, GAS, never N/A)
All changes get a branch. Plan must name the branch and include a merge-to-main step.
Push-to-remote step must be explicit.

Q2: Do the plan steps actually use branching? (3, GAS, never N/A)
Steps must create a feature branch and commit incrementally. Commit messages must follow
project conventions (conventional commits: feat/fix/chore/docs etc.). Risky changes must
include a git rollback path.

---

MCP GAS Workflow

Q3: Is local/remote file sync accounted for? (2, GAS)
mcp__gas__cat can return stale local. Specify remoteOnly: true for reads and verify after push. N/A: no remote file reads.

Q4: Are files in the right folders and in correct dependency order? (2, GAS)
Folders: addon code in inbox-crew/addon/, common modules in common-js/, HTML in html/, tests in test/. Order: require.gs at position 0, then base modules before consumers, tests last. Flag wrong folder placement or out-of-order dependencies. N/A: no new files.

Q5: Are the right mcp_gas tools used for each file type? (2, GAS)
HTML files must use write({..., raw: true}) (not plain write which adds CommonJS wrappers). .gs files use write without raw: true. cat paths must omit .gs extension. N/A: no file push/read operations.

Q6: Is there exec verification after each push? (2, GAS)
Each write (or write({..., raw:true})) must be followed by an exec to verify code loads. Push does not mean it works. N/A: no remote pushes.

Q7: If editing common-js modules, are mcp_gas templates also updated? (2, GAS)
CLAUDE.md: COMMON-JS_SYNC. Changes to shared modules must include dual updates. N/A: no common-js edits.

Q8: Does the plan account for GAS isolated execution state? (1, GAS)
Each exec() has isolated global state -- no persistence between calls. Data must go through Properties/Cache. N/A: no cross-exec state needed.

Q49: Does the plan respect V8 file parsing order? (2, GAS)
If any new file is added, or any file's position changes, verify that no loadNow module ends up with dependencies at higher file positions. loadNow modules must be positioned LAST, after all their transitive dependencies. Symptom of failure: "Module not found" at startup even though ls() shows the file exists.
N/A: plan adds no new files AND changes no file positions AND no loadNow modules exist in the project.

---

Deployment & Rollback

Q9: Is the deployment defined with target environment? (2, GAS)
GAS changes need push/deploy steps: write/write({...,raw:true})/rsync, exec verification, target env (dev/staging/prod). N/A: local-only files.

Q10: Is there a rollback plan if deployment goes wrong? (2, GAS)
Recovery path: revert commit + redeploy, versioned rollback, or hold previous deployment. Flag doGet/doPost/events changes without rollback note. N/A: no deployment.

---

Testing & Verification

Q11: Are tests updated for these changes? (2, GAS)
Interface changes need test updates. Bug fixes need regression tests. New functions need new tests. N/A: pure CSS/HTML visual changes.

Q12: Is there incremental verification at each step? (2, GAS)
Each step must have a checkpoint (exec, test, manual check). Flag all-testing-at-end. N/A: single atomic change.
For plans that modify sidebar/HTML files (sheets-sidebar/, common-js/html/): verification steps should reference the gas-sidebar skill procedures (launch sidebar → send prompt → wait for response → read response). A plan that says "open the sidebar and check it works" without citing the concrete gas-sidebar workflow is insufficient — the sidebar runs in a cross-origin iframe and requires specific DevTools automation patterns.

---

Standards & Conventions

Q13: Does the plan adhere to project standards and conventions? (3, Shared, never N/A)
CLAUDE.md: CommonJS wrappers, __events__, loadNow:true, write({..., raw:true}) for HTML, createGasServer/exec_api.
MEMORY.md: doGet null-return, result.error not result.success, ConfigManager namespaces.

Q14: Do new names follow existing codebase conventions? (1, Frontend)
Casing, module naming, config key patterns. N/A: no new names.

---

Simplicity & Architecture

Q15: Is this as simple as possible, but no simpler? (3, Shared, never N/A)
Over-engineering: unnecessary modules, premature abstractions, duplicated common-js logic, future-proofing.
Under-engineering: missing error handling on GAS APIs, missing null checks on sheet ops.

Q16: Are modified interfaces consistent with other interfaces? (2, Shared)
All callers identified and updated, return formats match siblings, events consistent. N/A: no export/signature changes.

Q17: Are step ordering and sequencing dependencies explicit? (2, GAS)
Clear DAG. Flag: refs to uncreated files, deploy before push, require() targets pushed after importers. N/A: single step.

Q41: Is the proposed change integrated into existing architecture or bolted on as an isolated addition? (2, Shared)
New code should extend existing modules, reuse existing patterns, and follow established data flows. Flag: new utility when an existing one covers the use case or could be extended; new file when an existing file handles the concern; new pattern when existing conventions already address it; additions that don't connect to the codebase's module structure or data flow. N/A: change is purely additive with no existing structure to integrate into.

---

Impact & Cleanup

Q18: Are there other impacted features not considered? (3, GAS)
Cross-ref changed modules against callers (grep require(), call sites, __events__). Flag unmentioned callers that may break. N/A: fully isolated, zero callers.

Q19: Is there any empty code that needs implementation? (2, GAS)
Flag stubs, TODOs, "implement later" without full spec. Allow explicitly phased delivery. N/A: no placeholders.

Q20: Is there dead code that should be removed? (2, GAS)
Old implementation marked for removal when replaced? Flag orphaned exports, unused handlers in changed modules. N/A: nothing replaced.

Q50: Does the plan introduce any GAS global namespace collision? (2, GAS)
Check: do any new or modified modules declare top-level vars/consts whose names match GAS built-in globals (Logger, Utilities, DriveApp, SpreadsheetApp, ScriptApp, UrlFetchApp, CacheService, PropertiesService, LockService, HtmlService, ContentService, MailApp, GmailApp, etc.)? loadNow modules are highest risk since they run at parse time. Also check require() aliases — const Logger = require(...) at module top level is safe; var Logger = ... outside a function is not.
N/A: plan adds no new modules AND no existing module is modified at its top-level scope.

Q51: Do new modules use the 3-param _main signature for debug logging? (1, GAS)
Any new CommonJS module (_main factory) should use function _main(module, exports, log). The log param is auto-injected by require.js and is a no-op when not enabled — zero runtime cost. Plans that include debugging/testing steps should also show how to enable it:
exec: setModuleLogging('folder/ModuleName', true) // enable during test
exec: setModuleLogging('folder/ModuleName', false, 'script', true) // disable after
N/A: plan adds no new CommonJS modules (no new _main factory files).

Q38: Are there unintended consequences from this plan that need to be addressed? (2, Shared)
Side effects beyond the stated goal: breaking existing workflows, changing user-facing behavior unintentionally, introducing performance regressions, altering data formats consumed by other systems, or shifting security boundaries. Flag anything the plan doesn't explicitly acknowledge. N/A: trivial isolated change with no external touchpoints.

Q39: Does the plan introduce logic duplicating existing implementations? (2, GAS)
Before adding new functions or modules, verify no equivalent already exists (grep callers, scan module registry). Flag plans that reimplement logic already in common-js or sibling modules without justification. N/A: no new functions or modules introduced.

Q40: Does the plan account for both state-exists and state-absent edge cases in persistent storage? (2, GAS)
State-exists risk: code that reads ConfigManager/Properties/Cache/Sheets and misinterprets values left by a prior version — old schema format, stale cache entry, conflicting user config from an earlier install. State-absent risk: code that reads state before it has ever been written — uninitialized ConfigManager/Properties key, cold Cache, missing sheet row or named range, first-run user. Flag: reads without null/existence check; writes that assume stored data is in the expected schema; feature paths with no initialization guard for first-run. N/A: plan introduces no reads from or writes to ConfigManager, Properties, Cache, Sheets, or any shared persistent storage.

---

Concurrency, Quotas & Runtime

Q21: Are there concurrency considerations? (2, GAS)
Shared state (Properties, Cache, sheets) needs locking. Triggers/background need concurrency plan. N/A: read-only, client-only.

Q22: Will the operation fit within the 6-minute execution limit? (2, GAS)
Batch ops, large sheet reads, chained APIs need runtime estimate and chunking. N/A: bounded quick ops.

Q23: Does the plan add new OAuth scopes? (2, GAS)
Adding scopes forces re-auth for all users. Note which APIs and user impact. N/A: no new GAS services.

Q24: Are operations idempotent -- safe to retry? (2, GAS)
Triggers/web apps can fire twice. Data mutations need dedup or check-before-write. N/A: read-only.

Q25: Are quota and rate limits accounted for? (1, GAS)
UrlFetch 20K/day, Properties 50 reads/min, runtime 6min, triggers 90min. N/A: no API/batch/trigger additions.

Q26: Are Properties/Cache payloads within actual limits? (1, GAS)
PropertiesService: 524,288 chars/value, 512KB total per store, 500 keys max. CacheService: 102,400 bytes/value, 250-char key max, FIFO eviction (not LRU — hot keys can still be evicted). Exceeding these silently fails or throws with no clear error. N/A: plan does not read/write PropertiesService or CacheService.

---

Security

Q27: Is input validated at trust boundaries? (2, Shared)
doGet/doPost params, form submissions, exec_api args need sanitization. Flag raw e.parameter, unescaped HTML, formula injection. N/A: no untrusted input.

---

Error Handling & Logging

Q28: Are errors handled gracefully with actionable messages? (2, Shared)
Try/catch on GAS APIs, user-facing messages (not stacks), fail-loud vs fail-silent noted. Consistent with ChatService format. N/A: no new error paths.

Q29: Is the logging strategy informative yet compact? (2, GAS)
setModuleLogging(pattern) over Logger.log(). Context without dumps. No sensitive data. N/A: no server logic changes.

---

UX & Frontend

Q30: Is there UX feedback during long operations? (1, Frontend)
Loading states, spinners, cancel support for >2s ops. N/A: no new UI server calls.

Q31: Are new UI elements accessible? (1, Frontend)
aria-* labels, tab order, focus management in iframes. N/A: no new interactive elements.

Q32: Are event listeners cleaned up to prevent memory leaks? (2, Frontend)
Sidebar reopens accumulate listeners. Flag setInterval, addEventListener without cleanup. N/A: no new listeners.

Q33: Is there a client-side error boundary for silent crashes? (1, Frontend)
window.onerror or try/catch around init. N/A: no new client logic.

Q34: Do new CSS styles avoid conflicts with Google's add-on CSS? (1, Frontend)
Namespace classes (.chat-btn not .btn). Avoid broad selectors. N/A: no new CSS.

---

LLM Maintainability

Q35: Are there token-optimized LLM comments where needed? (1, Frontend)
<!-- LLM: [module] [function] [5-8 word purpose] --> for WHAT. N/A: trivial/self-documenting.

Q36: Are there breadcrumb comments for non-obvious patterns? (1, Frontend)
WHY something exists: workarounds, undocumented behavior, intentional oddities. N/A: no non-obvious patterns.

---

Plan Legibility

Q43: Would any update materially improve plan legibility when run in Claude Code? (1, Frontend)
As a senior UI engineer running this plan in Claude Code: are steps numbered, are code blocks properly fenced, are section headers scannable, and are conditional branches (IF/ELSE) visually distinct? Flag plans with walls of prose, unnumbered multi-step sequences, or deeply nested logic that becomes hard to follow during execution. N/A: plan is a single atomic step or is already well-structured.

---

Gmail Add-On / CardService

Q44: Does the card structure follow stateless best practices? (2, GAS)
Cards must be rebuilt from scratch on each trigger invocation — CardService has no persistent card objects between calls. Evaluate: (a) State stored in PropertiesService or CacheService, not in card object references; (b) Cache keys use message-scoped prefixes (ctx_ + messageId, chat_ + messageId); (c) CacheService TTL appropriate to data lifetime (6 hours for classification, 1 hour for chat, 10 min for temp async state); (d) Async trigger pattern planned for long-running ops (LLM calls, external APIs) — saves state to PropertiesService, creates time-based trigger after 500ms, returns processing card with "Check Response" button, background fn saves result to CacheService, trigger cleaned up in finally block; (e) Trigger cleanup strategy explicit (user limit: 20 triggers; accumulation causes quota errors). Flag: mutable card references across invocations, global card caches, card.update() anti-patterns, missing trigger cleanup, LLM calls blocking the 30-second response limit without async pattern. N/A: no CardService usage in plan.

Q45: Are all card action handlers wired and exported? (2, GAS)
Every setOnClickAction, setOnChangeAction, setOnClickOpenLinkAction must reference a function that is globally visible or registered via __events__. Evaluate: (a) Action string in setFunctionName() matches an exported function name exactly (case-sensitive); (b) Handler functions in module.exports with __events__: true; (c) Parameters passed via setParameters({key: 'value'}) — strings only, objects must be JSON-serialized; (d) Parameter extraction uses e.commonEventObject.parameters.key; (e) Form inputs extracted safely: e.commonEventObject.formInputs[field]?.stringInputs?.value?.[0] with defaults; (f) Switch widgets set BOTH setValue('true') (submitted value) AND setSelected(boolean) (UI state); (g) ActionResponse pattern matches intent: pushCard for drill-down (adds back button), updateCard for refresh (no navigation change), popCard for back/cancel, popToRoot for reset after major action, setNotification for toast (mutually exclusive with navigation — navigation wins if both set). Flag: action string references non-exported function, handler names don't match any function in plan's file set, missing __events__: true, notification + navigation combined. N/A: no card actions in plan.

Q46: Is Gmail message access token handled correctly? (2, GAS)
GmailApp.setCurrentMessageAccessToken(e.gmail.accessToken) must be called as the FIRST line in every contextual trigger handler before any GmailApp.getMessageById() call. Evaluate: (a) Token set before ALL GmailApp operations in contextual handlers; (b) Token NOT cached across separate trigger invocations (isolated GAS state — caching breaks on new invocations); (c) Token NOT needed in homepage handlers (no e.gmail available there — accessing it crashes); (d) Draft creation uses message.createDraftReply() or message.createDraftReplyAll() for replies — NOT thread.createDraft() (creates new message, not reply); (e) Label operations use getOrCreate pattern: getUserLabelByName() then createLabel() if null (silent failure if label missing); (f) OAuth scopes in appsscript.json match actual operations: gmail.addons.execute, gmail.addons.current.message.readonly, gmail.modify (for drafts/labels/archive). Flag: missing token set before message access, token stored in Properties/global var for reuse across invocations, thread.createDraft() for replies, label ops without existence check, missing OAuth scopes for planned GmailApp operations. N/A: no Gmail message access in plan.

Q47: Is card navigation balanced (push/pop)? (2, GAS)
Every pushCard path must have a corresponding popCard, popToRoot, or explicit navigation reset path. Evaluate: (a) Detail/settings cards pushed via pushCard include a back button using popCard; (b) Navigation depth stays reasonable (3-4 cards max; ~10 card practical limit); (c) Major actions (send, archive, delete) use popToRoot to reset stack; (d) updateCard used for real-time refresh within a view (does not change navigation stack); (e) Error cards include back button — never dead-end the user; (f) No notification + navigation combined (navigation supersedes notification if both set). Flag: unbounded push depth without back navigation, pushed cards with no back button, orphaned card stacks (pushCard with no pop path), popCard called from card that was never pushed, using pushCard where updateCard is semantically correct (chat message refresh). N/A: single-card add-on with no navigation, or all interactions are updateCard only.

Q48: Are homepage and contextual triggers both covered? (2, GAS)
appsscript.json must declare both homepageTrigger (in addOns.common) and contextualTriggers (in addOns.gmail) when the add-on needs both entry points. Evaluate: (a) homepageTrigger.runFunction references an existing handler that does NOT access e.gmail (unavailable in homepage context); (b) Contextual trigger onTriggerFunction references an existing handler that calls setCurrentMessageAccessToken before any GmailApp use; (c) Handler functions check for e.gmail presence/absence when serving both contexts; (d) appsscript.json oauthScopes array includes all scopes needed by both trigger paths; (e) If compose trigger needed: composeTrigger section in addOns.gmail with selectActions; (f) If universal actions needed: universalActions section in addOns.gmail. Flag: missing trigger type in manifest for a planned entry point, homepage handler that crashes on missing e.gmail, contextual handler missing token set, function names in manifest don't match any planned function, OAuth scopes don't cover all planned Gmail operations. N/A: not a Gmail add-on (web app or Sheets-only).

---

Documentation

Q37: Does project documentation need updating? (1, GAS)
Identify affected project docs: MEMORY.md, CLAUDE.md, README, JSDoc. Update when: API behavior changes, new conventions established, module responsibilities shift, new config patterns added. N/A: no behavior/API changes.

---

Post-Implementation Review

Q42: Is there a plan to review all changes after all code is applied? (3, GAS, never N/A)
Plan must include a post-implementation section after all implementation steps:
(1) run /review-fix or /gas-review — loop until clean,
(2) run build/compile if applicable,
(3) run tests.
Steps 4–5 of CLAUDE.md POST_IMPLEMENT (fail recovery and PR creation) apply at runtime regardless of plan text — plan does not need to restate them.
Ensures regressions and secondary issues are caught before closing out the task.
Mandatory for all plans — cannot be skipped.

Rating

Rating	Criteria
READY	Gate 1 all PASS + Gate 2 all PASS
SOLID	Gate 1 all PASS + Gate 2 ≤ 2 NEEDS_UPDATE
GAPS	Gate 1 all PASS + Gate 2 > 2 NEEDS_UPDATE
REWORK	Gate 1 has any NEEDS_UPDATE

Score

(PASS_weight_sum) / (applicable_max_weight_sum) * 100 — summary metric alongside gate rating.
Q43 (weight 1) is included in applicable_max_weight_sum once evaluated post-loop; its result is appended to the scorecard separately under "Organization Quality (Q43)" but counts toward the score.

After Review Completes (standalone mode only)

After outputting the Final Scorecard:

1. REWORK gate (handled inside the convergence loop — not a post-loop step): Gate 1 is
   resolved by the pass_count >= 5 branch inside the loop. By the time the loop exits, Gate 1
   is either clean or the user has been asked and responded. If Rating is REWORK when the loop
   exits (user override or unresolvable): note the override in the scorecard. Do not re-run the
   REWORK check here — it was already handled inside the loop.

2. Q43 post-loop evaluation (plan legibility / organization):
   [Substitute plan_path and questions_path (resolved in Step 0) before spawning]
   Spawn a single Task (general-purpose, current team_name):

   name: "q43-evaluator"
   prompt: Evaluate Q43 from <questions_path>.
           Q43 checks: Are steps numbered? Are code blocks fenced? Are section headers scannable?
           Are conditional branches (IF/ELSE) visually distinct? Are walls of prose present?
           Skip content marked <!-- gas-plan --> or <!-- review-plan -->.
           Return one of:
             PASS — [one-sentence reason]
             NEEDS_UPDATE — [specific edit instruction: what to add/change and where]
           Send findings via SendMessage to team-lead (type: message, recipient: team-lead).
   
           Plan to evaluate: <plan_path> — read it with the Read tool, then evaluate Q43 above.

   Append "q43-evaluator" to spawned_evaluators.
   Wait for message (90s max). Timeout handling:
   IF no response after 90s:
   ⚠️ Q43 Evaluator Incomplete — proceed without Q43 evaluation.
   Add to scorecard: Organization Quality (Q43): ⚠️ Evaluator timed out — skipped
   Continue to step 3.
   IF NEEDS_UPDATE: apply one round of edits to the plan file.
   Add Q43 result to the Final Scorecard output under a new line:
   Organization Quality (Q43): [PASS | NEEDS_UPDATE — reason]

3. Use the Bash tool to run: touch ~/.claude/.plan-reviewed && rm -f <memo_file> — writes the gate marker so ExitPlanMode will pass; second command removes the convergence checkpoint (no longer needed after loop exits)

4. Team teardown: Send shutdown_request to all agents in spawned_evaluators (only agents that were actually launched — triage-skipped evaluators and any agents not appended to spawned_evaluators are never targeted), then call TeamDelete. (Teardown must complete before ExitPlanMode — the session context needed for TeamDelete is not available after exiting plan mode.)

5. Call ExitPlanMode immediately. Do not pause, do not ask "should I present the plan?"

The PreToolUse hook on ExitPlanMode checks for this marker and consumes it on success.
