GPT Orchestration Build

Convert findings into working software. Own the implementation result; do not merely redistribute the list or return another plan.

Establish the build contract

1. Read repository instructions and capture the branch, dirty-path ledger, relevant diffs, manifests, and available verification commands.
2. Confirm that the user authorized implementation. Treat review-only or audit-only requests as read-only.
3. Gather all supplied findings from the conversation, reports, plans, issues, test output, and working tree.
4. Normalize them into a finding ledger with:

• stable identifier and concise outcome;
• evidence and affected paths;
• confidence, severity, and user impact;
• prerequisites and conflicts;
• owner and write scope;
• acceptance test;
• final disposition.

1. Preserve pre-existing user changes. Never reset, checkout, stash, or overwrite unrelated work.

Validate before writing

Trace each finding to current repository truth. Mark it confirmed, already satisfied, duplicate, invalid, or blocked. Do not implement stale advice blindly. Research only the gaps needed to make a safe build decision; avoid restarting a broad audit unless the findings are unusable.

If current APIs, dependencies, standards, or security guidance affect the implementation, verify them with primary sources. Adapt the result to the repository's actual stack.

Plan implementation waves

Order confirmed work by dependency and blast radius:

1. contracts, schemas, and shared types;
2. core services and persistence boundaries;
3. SDKs, adapters, and integration seams;
4. product routes and user-facing behavior;
5. cleanup, documentation, and generated artifacts;
6. independent verification and residual-gap scan.

Use the runtime's available concurrency, counting the orchestrator as a slot. Give one writer ownership of each file or tightly coupled subsystem. Latest-only is the default: use confirmed sol_engineer (gpt-5.6-sol) for hard integration, terra_worker (gpt-5.6-terra) for bounded implementation, terra_explorer for read-heavy gaps, and luna_verifier (gpt-5.6-luna) for mechanical checks. If the native spawn schema cannot prove an exact route and the sibling gpt-engineer skill is installed, use its guarded CLI runner. Otherwise never use a generic, inherited, model-less, GPT-5, GPT-5.4, Spark, or Claude substitute; keep the work with the exact-model parent or report the limitation.

Every writer contract must include exact paths, success criteria, prohibited side effects, required tests, baseline constraints, and expected handoff evidence. Keep overlapping work read-only.

Build every confirmed finding

For each wave:

1. Assign non-overlapping changes.
2. Continue useful integration work while agents run.
3. Inspect every returned diff rather than trusting the summary.
4. Reject scope drift, placeholder replacements, silent fallbacks, and unverified completion claims.
5. Run focused tests before dependent work begins.
6. Update the finding ledger immediately.

Do not drop difficult items. A confirmed in-scope finding must end as implemented or blocked by a concrete missing authority, credential, external dependency, or mutually exclusive user decision. Do not use deferred unless the user explicitly accepts deferral.

Integrate and prove the result

After all waves, run checks selected by the changed behavior and acceptance criteria:

• regenerate code only when its source schema changed and regenerate lockfiles only when dependency inputs changed;
• always run diff hygiene plus the focused lint, static analysis, type checks, tests, build, or runtime checks that cover the affected system;
• reserve repository-wide gates and production builds for cross-cutting changes, broad completion claims, or explicit acceptance criteria;
• exercise the affected user path against a verified local or disposable target;
• inspect scripts before running them and never let a smoke command default to production;
• run a residual search for the original findings and incomplete-code markers;
• compare the final worktree with the captured baseline.

Keep credentialed, destructive, deployment, messaging, merge, and push actions outside scope unless the user separately authorized them.

Tear down the build fleet

After accepting the last implementation result, wait for every required handoff and inspect the live agent tree. Interrupt superseded or stale agents, then verify that no bounded worker remains active.

Track every background process or temporary resource launched by the fleet. Preserve evidence, then stop and reap task-owned subprocess groups, watchers, servers, and listeners and remove task-owned temporary worktrees unless the user explicitly requested continued runtime. Classify ownership using agent state, parent process, working directory, launch time, and recorded PID or resource identifier. Never kill by process name alone, and never terminate shared MCP services, the host application, another task's cohort, or an unclassified process. Report host-retained helpers when the runtime provides no safe task-scoped teardown.

Close the ledger

Return the outcome first, followed by the finding ledger disposition summary, changed subsystems, verification matrix, fleet teardown result, preserved user work, and exact blockers. Claim completion only when every confirmed finding has an acceptance result, no required build work remains, and task-owned resources have been reclaimed or explicitly retained.
