GodotMaker Build

$ARGUMENTS

You are implementing a Godot game by dispatching Worker subagents. Risk tasks first, then main tasks — both surfaced from PLAN.md, which is scoped to the current tag (read the **Tag:** header at the top of PLAN.md). You do NOT build the whole game in one go; later tags will add features on top of this one.

Session Setup

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

Resume Check

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

• If project.godot does not exist → STOP. Tell user to run /gm-scaffold first.
• If ROADMAP.md does not exist → STOP. Tell user to run /gm-gdd first.
• If no event with role == "gdd" exists anywhere in the file → STOP. Tell user to run /gm-gdd first.
• If PLAN.md is missing the **Tag:** header → STOP. Tell user the file is stale and to re-run /gm-gdd to regenerate it for the current tag.

Read .godotmaker/verify_report.json if it exists.

Define pending verify feedback as:

• .godotmaker/verify_report.json exists.
• Its top-level result is "fail".
• Its ts is later than the latest role == "build" event in stage.jsonl, or there is no prior build event.

Apply the resume gates in this order:

• If pending verify feedback exists → proceed to Step 0, even if the last event is build and all PLAN.md tasks are already verified.
• If the last event has role == "build" AND all PLAN.md tasks are verified → STOP. Tell the user:

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

• Otherwise → proceed (this includes resume from interrupted run AND new tasks added by reviewer).

Then read context:

• PLAN.md → current tag's **Tag:** header + Tag Mechanics + Inherited Mechanics + Playable Unit + pending/in_progress/completed tasks (anything not verified)
• STRUCTURE.md → architecture and build order (current tag scope: previous tags' systems already exist on disk and may be touched only when PLAN.md explicitly lists a refactor task for them)
• 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 (cross-tag accumulating notebook) → avoid repeating known mistakes
• docs/tags/<prev_tag>/STRUCTURE.md (only if PLAN.md has Inherited Mechanics or refactor tasks touching prior systems) → know what already exists before adding/refactoring

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 PLAN.md/STRUCTURE.md/ASSETS.md.
4. Worker reports are validated by hooks — incomplete reports are blocked and retried.
5. MUST NOT skip stages. Fix issues first; apply the evidence-based five-repair gate in references/repair-attempt-accounting.md.
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. Tag scope discipline. Workers MAY touch files from previous tags only if PLAN.md has an explicit refactor / fix task naming those files. New systems live alongside existing ones; do not silently rewrite prior-tag code as a "cleanup" detour.
8. Build the Playable Unit. PLAN.md tasks must integrate into the Playable Unit's player-experienced path. Do not treat isolated systems, simulation helpers, or unit tests as sufficient.

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)

Tasks transition forward only:

pending → in_progress → completed → verified

• Never move backward (e.g., verified → pending)
• Never skip states
• Update PLAN.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) describing the fix. The original task stays verified. The new task goes through the full lifecycle. (REJECT or SKIP findings go to MEMORY.md instead — 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.

Build Cycle

The cycle has three steps and runs until convergence (PLAN clean and the last verify+review pass produced no new ACCEPTED tasks). Reviewer is invoked once per cycle iteration — after every PLAN task reaches completed, not on a worker-count cadence.

Step 0 — Process Verify Feedback

Run this step before Step 1 only if pending verify feedback exists. Otherwise → skip to Step 1.

Translate failures into pending tasks at the bottom of PLAN.md.

Project-code tasks (any checks.<name>.result == "fail") — go through the normal Worker → Verifier → Reviewer cycle:

• checks.build.errors[] → one task per distinct compile error (file + line + message in Notes).
• checks.unit_tests.failures[] → one task per failing test. If failed > 0 but failures[] is empty, one task: "investigate test runner output".
• checks.lint.issues[] → group by file when multiple issues hit the same file; otherwise one per issue.
• checks.lint.format_drift → one task: "run <format_drift.command> to format the drifted files (<file_count> files)".
• checks.static_check.issues[] → one task per issue, using check as the title prefix (e.g. missing_unit_test: s_player_input). For unknown check discriminators, use the raw value verbatim — generic project-code fix.

Config tasks (any checks.<name>.result == "error", paired with one tooling_notes[] entry) — main agent applies directly, NO worker dispatch:

• Routable fallback (exclude_file / scope_narrow / add_gdlintrc_rule / skip_check) WITH operand present (per the fallback table in gm-verify/SKILL.md Section B) → apply the structured edit using the note's operand. Mark verified after the next verify round confirms the tool no longer crashes there. Hard Rule 1 only restricts .gd/.tscn/.tres.
• escalate, OR routable with missing operand, OR unknown discriminator → do NOT auto-fix. Surface tool + error + crashed_on (and any original suggested_fallback) to the user verbatim, halt the build cycle, leave the task pending until the user resolves the underlying issue.

Do NOT delete project code as a "fix" for a tool crash.

Step 1 — Dispatch Workers (until PLAN is clean)

• 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.

• Use subagent_type: "worker". Each worker implements ONE game mechanic function + its tests.
• Include the relevant Playable Unit fields in each worker brief.
• For visual tasks, fill the Asset Runtime Snapshot and

Visual Asset Contract sections 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 against an invented path.

• Max 3 in parallel with disjoint file sets via isolation: "worktree" (send all Agent calls in one message).
• After each worker reports DONE, mark its task in PLAN.md as completed.
• main_scene retarget is your job. Scaffold leaves run/main_scene="res://scenes/main.tscn" (placeholder). After the worker that creates this tag's entry scene (per SCENES.md) completes and the .tscn is on disk, Edit project.godot's [application] run/main_scene to res://<path>.
• Continue dispatching until PLAN.md has no pending or in_progress tasks (everything is completed or verified). Then go to Step 2.

Step 2 — Verify + Review Pass

Run ONE verifier, then ONE reviewer, on the integrated state:

Verifier:

• Read references/verifier-dispatch.md for the brief template
• Use subagent_type: "verifier". Pass all completed-but-not-yet-verified workers' deliverables.
• On FAIL: add NEW pending fix tasks in PLAN.md. Failed tasks stay completed. Go back to Step 1.
• On PASS: update those tasks from completed → verified.

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.
• Ask the reviewer to check gameplay authenticity for the integrated Playable Unit.
• 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 fix task to PLAN.md.
• REJECT → finding is wrong; append a record to MEMORY.md "Reviewer Triage Log" section (citation required for critical/major).
• SKIP → finding is real but not worth fixing now; same MEMORY.md section (citation required for critical/major).
• Defaults when uncertain: critical/major → ACCEPT; minor → SKIP.
• If you ACCEPTED any findings → go back to Step 1.
• If verifier passed AND reviewer added zero ACCEPTED tasks → exit cycle (proceed to "When Done").

The build cycle continues until ALL tasks are verified AND the most recent verify+review pass produced no new ACCEPTED tasks AND the verifier passed.

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

Memory System

MEMORY.md              <- Index + cross-cutting knowledge
memory/
  {system_name}.md     <- Per-system details (template: .claude/templates/memory_subsystem.md)

• Read MEMORY.md before dispatching workers
• Update after every verification round (you write, not workers/reviewers)

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: PLAN.md status, STRUCTURE.md architecture, worker briefs (~200 tokens), worker summaries (~100 tokens), verification results, design decisions.

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

When context gets large: Summarize completed phases. Reference documents by path. Write decisions to MEMORY.md for recovery after compaction.

When Done

When ALL PLAN.md tasks are verified AND the most recent verify+review pass produced no new ACCEPTED fix tasks:

1. From the project root run python tools/append_stage_event.py build to append a {"role": "build", "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(build): <Tag>"
3. Inform the user: Build complete. Recommended next: /gm-verify
