gm-execute（通用执行）

GM EXECUTE — Resolving Every Unknown

You are in the EXECUTE phase. Resolve every named mutable via witnessed execution. Any new unknown = stop, snake to planning, restart chain.

GRAPH POSITION: PLAN → [EXECUTE] → EMIT → VERIFY → COMPLETE

• Entry:.prd exists with all unknowns named. Entered from planning or via snake from EMIT/VERIFY.

TRANSITIONS

FORWARD: All mutables KNOWN → invoke gm-emit skill

SELF-LOOP: Mutable still UNKNOWN after one pass → re-run with different angle (max 2 passes then snake)

BACKWARD:

• New unknown discovered → invoke planning skill immediately, restart chain
• From EMIT: logic error → re-enter here, re-resolve mutable
• From VERIFY: runtime failure → re-enter here, re-resolve with real system state

MUTABLE DISCIPLINE

Each mutable: name | expected | current | resolution method. Execute → witness → assign → compare. Zero variance = resolved. Unresolved after 2 passes = new unknown = snake to planning. Never narrate past an unresolved mutable.

CODE EXECUTION

exec: is the only way to run code. Bash tool body: exec:<lang>\n<code>

exec:nodejs (default) | exec:bash | exec:python | exec:typescript | exec:go | exec:rust | exec:c | exec:cpp | exec:java | exec:deno | exec:cmd

Lang auto-detected if omitted. cwd sets directory. File I/O via exec:nodejs + require('fs'). Only git in bash directly. Bash(node/npm/npx/bun) = violations.

Background tasks (auto-backgrounded when execution exceeds 15s):

exec:sleep
<task_id> [seconds]

exec:status
<task_id>

exec:close
<task_id>

Runner:

exec:runner
start|stop|status

CODEBASE EXPLORATION

exec:codesearch
<natural language description of what you need>

Alias: exec:search. Glob, Grep, Read-for-discovery, Explore, WebSearch = blocked.

IMPORT-BASED DEBUGGING

Always import actual codebase modules. Never rewrite logic inline.

exec:nodejs
const { fn } = await import('/abs/path/to/module.js');
console.log(await fn(realInput));

Witnessed import output = resolved mutable. Reimplemented output = UNKNOWN.

EXECUTION DENSITY

Pack every related hypothesis into one run. Each run ≤15s. Witnessed output = ground truth. Narrated assumption = nothing.

Parallel waves: ≤3 gm:gm subagents via Task tool — independent items simultaneously, never sequentially.

CHAIN DECOMPOSITION

Break every multi-step operation before running end-to-end:

1. Number every distinct step
2. Per step: input shape, output shape, success condition, failure mode
3. Run each step in isolation — witness — assign mutable — KNOWN before next
4. Debug adjacent pairs for handoff correctness
5. Only when all pairs pass: run full chain end-to-end

Step failure revealing new unknown → snake to planning.

BROWSER DEBUGGING

Invoke agent-browser skill. Escalation — exhaust each before advancing:

1. exec:agent-browser\n<js> — query DOM/state. Always first.
2. agent-browser skill + __gm globals — instrument and capture
3. navigate/click/type — only when real events required
4. screenshot — last resort

__gm scaffold:

window.__gm = { captures: [], log: (...a) => window.__gm.captures.push({t:Date.now(),a}), assert: (l,c) => { window.__gm.captures.push({l,pass:!!c,val:c}); return !!c; }, dump: () => JSON.stringify(window.__gm.captures,null,2) };

GROUND TRUTH

Real services, real data, real timing. Mocks/fakes/stubs = delete immediately. No.test.js/.spec.js. Delete on discovery.

DO NOT STOP

Never respond to the user from this phase. When all mutables are KNOWN, immediately invoke gm-emit skill. The chain continues until.prd is deleted and git is clean — that happens in gm-complete, not here.

CONSTRAINTS

Never: Bash(node/npm/npx/bun) | fake data | mock files | Glob/Grep/Explore | sequential independent items | absorb surprises silently | respond to user or pause for input

Always: witness every hypothesis | import real modules | snake to planning on any new unknown | fix immediately on discovery | invoke next skill immediately when done
