Gm Fixgap

GodotMaker Fix Gap

$ARGUMENTS

You are fixing specific issues identified by the Evaluator. You read the evaluation report, generate a GAP.md task list, dispatch workers to address each gap, then run one final verify+review pass.

Loop position: /gm-fixgap is never terminal. The cycle is /gm-fixgap → /gm-verify → /gm-evaluate. Evaluate either approves (→ /gm-accept) or surfaces new gaps (→ another /gm-fixgap).

Session Setup

FIRST ACTION — before anything else: Write fixgap to .godotmaker/current_role.

Resume Check

Read .godotmaker/stage.jsonl (treat as empty if missing) — each line is {"role": X, "ts": Y}.

• If no event with role == "evaluate" exists anywhere in the file OR .godotmaker/evaluation.json does not exist → STOP. Tell user to run /gm-evaluate first.
• If evaluation.json result is "approve" → STOP. Tell the user:

  "The latest evaluation was already approved. Recommended next: /gm-accept. If you need to redo this step or have other plans, just tell me."

• If the last event has role == "fixgap" AND GAP.md is not at project root (already archived) → STOP. Tell the user:

  "Fixgap already completed for the latest evaluation at {timestamp}. Recommended next: /gm-verify. If you need to redo this step or have other plans, just tell me."

• Otherwise → proceed (fresh fixgap or repeat fixgap is both valid).

Then read context:

• GAP.md (if present) → existing fix progress; find tasks not yet verified. If missing, Step 1 will generate it from evaluation.json (and verify_report.json).
• .godotmaker/evaluation.json → the source of truth for product-layer issues to fix
• .godotmaker/verify_report.json → mechanical-layer failures from the most recent verify
• PLAN.md → read-only; current tag's **Tag:** header tells you which tag's gaps you're fixing. The same tag-scope discipline as gm-build applies: previous tags' code is touchable only when a GAP item explicitly names it.
• STRUCTURE.md → architecture (fixes need to respect existing system boundaries)
• ASSETS.md → the generated-runtime authority; for a visual task, derive each asset with tools/asset_result_registration.py --snapshot
• MEMORY.md index + sub-files → stable architecture decisions and project constraints

Hard Rules

Asset Runtime Authority

ASSETS.md is the sole runtime-asset authority. For a visual task, derive the snapshot with tools/asset_result_registration.py --snapshot and never read a stable entry, manifest pointer, or root index. The snapshot resolves generated and complete user-provided runtime rows, including uniquely named rows introduced by earlier tags.

1. You CANNOT write .gd/.tscn/.tres directly. All game code goes through Worker dispatch.
2. You and your workers CANNOT write to e2e/ directory. E2E tests are owned by the Evaluator.
3. Workers CANNOT modify GAP.md/PLAN.md/STRUCTURE.md/ASSETS.md.
4. Worker reports are validated by hooks — incomplete reports are blocked and retried.
5. Only fix what evaluation.json or a fresh verify_report.json identified. Do not add features or refactor unrelated code.
6. MUST NOT self-certify completion. Dispatch verifiers, then reviewers. Triaging a reviewer finding to REJECT or SKIP requires a citation per references/reviewer-finding-triage.md (mandatory for critical/major; optional for minor).
7. Do not promote non-blocking visual findings. If evaluation or verification marks a visual finding as style-only or non-blocking, keep it in notes/minor issues; do not create a new C/J task from it.

Honest Reporting

• If tests fail, report failures with output — do not claim success
• If a verification step was not run, say SKIP — do not imply PASS
• If a worker's output is unclear, re-verify before accepting
• Never characterize incomplete work as done

Plan Discipline (Single-Direction State)

GAP.md tasks transition forward only:

pending → in_progress → completed → verified

• Never move backward (e.g., verified → pending)
• Never skip states
• Update GAP.md IMMEDIATELY when a task changes status

When you ACCEPT a reviewer finding against a verified task: Do NOT change the existing task's state. Add a NEW task (status pending) in GAP.md describing the fix. The original task stays verified. The new task goes through the full lifecycle. REJECT and SKIP do not create tasks; see references/reviewer-finding-triage.md.

This way the state is always monotonic and the audit trail is preserved.

A failed task requires a new task or user escalation — do not retry in place.

Do NOT update PLAN.md task statuses — fixgap operates from evaluation.json gaps, not the original plan.

Build Cycle

Step 1 — Read Evaluation (+ Verify Feedback), Generate or Resume GAP.md

GAP.md may need tasks from two sources:

1. .godotmaker/evaluation.json — product-layer issues found by the evaluator. Always processed.
2. .godotmaker/verify_report.json — mechanical-layer failures from the most recent verify pass. Processed only when fresh.

1a. Pull issues from evaluation.json

Create one critical evaluation-source GAP task for each playable_unit.rows.* entry with result == "fail". Include the row key, test path, and evidence entries. Fix the game code or runtime path. Do not reduce the PLAN.md or e2e/ contract.

For each E2E-sourced issue, decide the repair path before writing GAP tasks:

• Fix runtime behavior when the observable gameplay requirement is missing.
• Add or expose deterministic test interfaces when evidence includes requested_test_interface:.
• Escalate back to /gm-evaluate when the E2E assertion or scenario is wrong.
• Change normal gameplay behavior, balance, progression, content, or timing only when the evaluation evidence cites a GDD.md or PLAN.md requirement.

Copy observed_gap: and requested_test_interface: evidence entries into the GAP task when present.

GAP tasks must preserve the normal gameplay flow while satisfying the observable requirement or requested test interface.

• critical_issues — must fix all (→ task IDs C1, C2, …)
• major_issues — fix as many as possible (→ task IDs J1, J2, …)
• gameplay_issues — fix only if related to a critical/major (→ G1, G2, …)
• minor_issues — skip unless trivial

Evaluation-source visual tasks must cite the blocking finding reported by evaluation. Do not create a C/J task from a style-only or non-blocking visual finding. For blocking visual tasks, copy the relevant evaluation.json.visual_checks scene, reference, captures[], latest vqa_calls[].context, and latest vqa_calls[].log into the GAP task.

1b. Pull failures from verify_report.json

Run this sub-step only if .godotmaker/verify_report.json exists, result == "fail", and its ts is later than the most recent role == "fixgap" event in stage.jsonl (or there is no prior fixgap event). Otherwise (file missing, result == "pass", or stale ts) → skip 1b; GAP.md comes from 1a only.

Translate failures into tasks using the existing C / J prefixes — verify-source tasks share the numbering pool with evaluation-source tasks. Each task carries both a classification (C/J) and an execution mode (worker / main-agent-direct / escalate-to-user); Step 3 follows the execution mode without re-classifying.

Project-code tasks (checks.<name>.result == "fail") — execution = dispatch worker (normal Worker → Verifier → Reviewer cycle):

• checks.build.errors[] / checks.unit_tests.failures[] → C (compile/runtime failures block forward progress).
• checks.unit_tests with failed > 0 and empty failures[] → C, one task: "investigate test runner output".
• checks.static_check.issues[] of check == "missing_unit_test" → J (gap, not a hard block).
• Other checks.static_check.issues[] → C (project-completeness gate).
• checks.lint.issues[], checks.lint.format_drift → J (technical debt).
• Unknown static_check.issues[].check discriminator → use the raw value verbatim, default C.

Config tasks (checks.<name>.result == "error", paired with tooling_notes[]):

• Routable fallback WITH operand present (per the fallback table in gm-verify/SKILL.md Section B) → J, execution = main-agent-direct (apply the structured edit using the operand; Hard Rule 1 only restricts .gd/.tscn/.tres; mark verified after the next verify round confirms the crash is gone). NO worker dispatch.
• escalate, OR routable with missing operand, OR unknown discriminator → C, execution = escalate-to-user (surface tool + error + crashed_on and any original suggested_fallback verbatim, halt the cycle, leave pending until the user resolves it). NO worker dispatch.

Each task records its origin via a Source: verify_report.json | evaluation.json line in the task block (and verify / evaluation in the Task Status table). Numbering follows insertion order — existing rows keep their numbers, new rows get the next available number per letter. Execution priority dispatches verify-source before evaluation-source regardless of number.

1c. Write or merge GAP.md

If GAP.md does not exist: Generate it from .claude/templates/GAP.md. Within each letter list verify-source tasks first (so they get the lower numbers), then evaluation-source. All tasks start as pending. Record both source timestamps in the header — Source Evaluation: <evaluation iteration / ts> and (when applicable) Source Verify: <verify_report ts>.

If GAP.md already exists:

• Source Evaluation header differs from current evaluation.json → archive and generate a fresh one.
• Header matches AND 1b applies → append new verify-source tasks as pending rows with the next available number per letter; existing rows keep their numbers and statuses. Update the Source Verify header to the new ts.
• Header matches AND 1b does not apply → resume (skip already-verified tasks).

Backward compatibility (per-row). Apply on each row independently — interrupted upgrades leave mixed-annotated state:

• Row missing Source: line or Source column entry → treat as evaluation, fill when you next touch that row.
• Row already annotated → leave its Source: as-is.
• New verify-source rows always include both the Source: line and the column entry.

Step 2 — Plan Fixes

For each non-verified task in GAP.md:

1. Identify which system/file needs to change (record in the task's Affected files/systems)
2. Determine if the fix is code (dispatch worker) or config (you can do it)
3. Group related issues that touch the same files into one worker brief

Step 3 — Dispatch Workers

Worker-dispatch tasks only — Step 1b classified main-agent-direct and escalate-to-user tasks; handle those per their classification, not here.

• Read references/worker-dispatch.md for the brief template.
• Read and apply references/repair-attempt-accounting.md after every worker handoff. Increment dispatch_count for the handoff, then classify it from the report evidence before changing any retry counter or task state.
• Dispatch verify-source before evaluation-source within pending.
• Use subagent_type: "worker". Max 3 in parallel with disjoint file sets via isolation: "worktree".
• In each brief, paste the specific finding from GAP.md, the file(s) to modify, and the correct behavior from GDD.md.
• For visual tasks, fill Asset Runtime Snapshot from references/worker-dispatch.md. The snapshot is tools/asset_result_registration.py --snapshot output pasted verbatim. If it fails for an asset, report its error instead of dispatching the task against an invented path.
• For blocking evaluation-source visual tasks, fill Visual Asset Contract and Visual Self-Check from references/worker-dispatch.md.
• Update task status pending → in_progress when dispatched, in_progress → completed when worker reports DONE.

Step 4 — Final Verify + Review (single pass after all fixes)

Unlike gm-build, fixgap does NOT batch every ≥N workers. Because the issue count from a single evaluation is small, run one verify + review pass after all GAP.md tasks reach completed.

Verifier:

• Read references/verifier-dispatch.md for the brief template
• Use subagent_type: "verifier". Pass all completed workers' deliverables.
• For evaluation-source visual tasks, fill the Visual Verification section from references/verifier-dispatch.md, including the worker self-check result when present.
• A new FAIL task must cite an unresolved blocking finding or a blocking regression.
• On FAIL for a task: add a NEW pending task in GAP.md (the failed task stays completed). Loop back to Step 3.
• On PASS: update those tasks from completed → verified.

If verification exposes a design constraint conflict, stop splitting it into smaller visual tasks. Record the conflict in GAP.md notes, choose the interpretation already stated by SCENES.md if clear, or escalate for a design decision.

Reviewer (after verifier passes):

• Read references/reviewer-dispatch.md for the brief template
• Use subagent_type: "reviewer". Reviewer reports back; do not let it modify project files.
• Include Asset Runtime Snapshot when reviewed files use visual assets.
• Triage each finding per references/reviewer-finding-triage.md into one of three options:
  • ACCEPT → add NEW pending task to GAP.md.
  • REJECT → finding is wrong; do not create a task (citation required for critical/major).
  • SKIP → finding is real but not worth fixing now; do not create a task (citation required for critical/major).
• Defaults when uncertain: critical/major → ACCEPT; minor → SKIP.
• If you ACCEPTED any findings → loop back to Step 3.

The cycle ends when ALL GAP.md tasks are verified AND the most recent review round added no ACCEPTED tasks.

Step 5 — Archive GAP.md

Move the completed GAP.md to .godotmaker/gaps/<source-evaluation-iteration>/GAP.md so the project root is clean for the next round.

Retry Limits

Five effective production repairs, not five dispatches, are the only failure gate. Apply references/repair-attempt-accounting.md: incomplete handoffs and orchestration failures use its no-progress process, keep the task continuable, and do not consume the repair budget.

Parallel Worker Rules

• Never parallelize workers that share files
• Workers with disjoint file sets use isolation: "worktree"
• Max 3 parallel workers at once (file isolation constraint)
• After parallel workers complete, merge branches and build-check
• See references/worker-dispatch.md → Parallel Worker Dispatch for merge procedure

Architecture and Constraints Record

MEMORY.md              <- Architecture and constraints index
memory/
  {system_name}.md     <- Detailed system architecture and constraints

• Read MEMORY.md before dispatching workers.
• Write only stable architecture decisions or project constraints. Do not record task history, failures, gotchas, workarounds, reviewer triage, or other dynamic learning.
• Do not update MEMORY.md when no durable architecture or constraint changed.
• Where the runtime exposes SubagentStop lifecycle hooks (currently Claude Code and Codex), Worker failures become diagnostic worker_error events, not project rules or prompt context for the next dispatch.

Available Skills & Tools

Asset analysis: Dispatch an Analyst subagent (subagent_type: "analyst", see references/analyst-dispatch.md) when you need to analyze user-provided assets.

Context Management

Your context window is finite. Protect it:

In your context: GAP.md status, STRUCTURE.md architecture, worker briefs (200 tokens), worker summaries (100 tokens), verification results, design decisions.

Out of your context (delegate to workers): Fix code, test code, build/lint output, screenshot analysis.

When context gets large: Summarize completed fixes and reference documents by path. Do not use MEMORY.md as a context-recovery log.

When Done

E2E handoff

Handoff only after runtime GAP work is complete and the remaining failure is an E2E assertion, scenario, capture, or capture-timing defect.

1. Keep affected GAP tasks non-verified; do not archive GAP.md.

2. Add an Evaluator handoff note with the source evaluation, runtime evidence location, and failing E2E/capture location.

3. From the project root, run:

   python tools/append_stage_event.py fixgap --outcome=handoff --next_role=evaluate --reason=evaluator_owned_e2e
   

4. Commit with git add -A && git commit -m "chore(fixgap): evaluator handoff <Tag>".

5. Inform the user: FixGap handed off E2E evidence to /gm-evaluate.

Ordinary completion

After all GAP.md tasks are verified, the final reviewer added no new tasks, and GAP.md has been archived:

1. From the project root run python tools/append_stage_event.py fixgap to append a {"role": "fixgap", "ts": "<server-generated UTC>"} line to .godotmaker/stage.jsonl. Do NOT hand-write the JSON or the timestamp — the helper exists so the timestamp comes from the system clock, not your own output.
2. git add -A && git commit -m "chore(fixgap): <Tag>"
3. Inform the user: Fixgap complete. Recommended next: /gm-verify (then re-run /gm-evaluate to confirm the gaps are closed).
