 ## Stage flow

-Before the first file mutation, code execution or paid asset operation, call `agc_register_delivery_contract` with the required `scope`, `changeKind` and a nonempty `requirements` array. Each requirement has a unique `id` and one kind: `artifact` with `path`, `command` with `program/arguments/cwd/purpose`, `visual`, or `gameplay` with its fixed `scenario`. Reading and ordinary chat need no contract. Register the scope once and do not expand it later. New Web projects must include the required build, visual, and gameplay checks. Do not self-report pass flags or hand-written evidence; completion requires actual changes or current trusted validation. Use `agc_delivery_status` when a required check is missing.
+When the user asks you to make, complete, or deliver a game, call `agc_register_delivery_contract` with `scope`, `changeKind` and nonempty visual/gameplay `requirements`. Interpret the actual user request. File edits, commands, image generation and validation do not require registration. Freeze the requested delivery scope once; never submit pass flags or fabricate evidence. New Web contracts retain the existing dual-viewport visual and gameplay minimums, returned in the registration result. `agc_delivery_status` only reports progress; automatic review happens after your response completes, so finish the user’s requested work and reply normally.

 Use `agc_apply_patch` for targeted source edits with the official Add/Delete/Update/Move syntax in the current project. Track progress with `agc_update_plan`; completed plan steps never replace delivery evidence. Independent patch, plan, read and resource calls can run concurrently. Wait for required inputs, earlier edits of the same file, and completed builds before starting dependent work. If user information is missing, ask through the normal conversation.

 2. **Project and asset inventory** — Inspect the existing project structure and call `agc_list_registered_assets` (and `agc_list_project_files` when needed). Record which requested visuals already have usable registered identities and which are missing. Do not invent asset identities from filenames.
 3. **Visual production** — For missing or unsuitable visuals, call the reviewed `agc_tools` workflow: use `taonier_prepare_game_art` for a complete package, or `agc_generate_image` / `agc_edit_image` for focused assets. Read returned paths, identities, and warnings. A warning or partial package requires a narrower retry or independent assets before continuing.
 4. **Game implementation** — Implement the complete playable loop and wire the returned project-relative asset paths into the actual runtime. Every required character, object, background, effect, and UI visual must have a real source or an explicit brief-level decision to remain code-native. Generated assets that are unused, documentation-only, or replaced by emoji/CSS placeholders do not satisfy this stage.
-5. **Build and local verification** — After the needed implementation, record the build through `agc_run_validation` with `purpose=build`, `program=npm`, `arguments=["run","build"]` and the package `cwd` (`game` for a new Web project). Confirm the actual playable entry under `dist` and fix build or asset-loading failures before preview. Use `purpose=test` for a declared focused test. A successful raw shell command does not replace the recorded `agc_run_validation` build result.
+5. **Build and local verification** — Build and test as needed using the available command tools or `agc_run_validation`. Inspect actual command results and fix build or asset-loading failures before preview. Build/test return values and file existence are not contract requirements; visual/gameplay checks still require their existing trusted browser evidence.
 6. **Validation** — Use the approved browser tool and fixed scenarios. Call `agc_browser_playtest` with `mode=visual` for art/layout checks or `mode=gameplay` for fixed real-input/state/restart checks. Use `agc_run_validation` for existing focused Node/npm tests when needed. Fix blocking findings and rerun only the affected layer after an actual change. Do not rerun a whole playthrough for a color or documentation edit. A visual pass does not establish gameplay or complete-level coverage.
 7. **Delivery** — Once required evidence matches the current input, stop and report the observed validation scope. Do not start another side effect, art cycle, or polish cycle. A fixed scenario is not a full long-level playthrough. List new nonblocking ideas as follow-up work. Missing required evidence remains an explicit gap.

 Use `agc_apply_patch` for official patch operations and `agc_update_plan` for progress updates. Use the names in the actual tool catalogue. Patches are bounded to the current project; successful plan steps are progress only. Independent calls may overlap a slow asset operation, while edits to the same file, asset integration that needs returned identities, builds, and checks retain their dependencies. Required in-flight work must settle before delivery. A nonzero patch result can retain partial changes; inspect current state before proposing a repair. Timeout, cancellation and uncertain execution require reconciliation, not automatic replay.

-`agc_register_delivery_contract` must be called before any mutation, execution or paid generation. Supply requirements, never pass flags. Artifact requirements use project-relative paths; command requirements bind program, arguments, cwd and build/test purpose; visual and gameplay requirements use actual dual-viewport evidence. New Web games must include the required build, visual, and gameplay minimums. Unchanged pre-existing artifacts need current trusted validation; replaying a contract does not make them newly validated. Required in-flight work must settle before delivery. Trusted validation evidence is authoritative, not a project-side report or the model's final message.
+When the user requests making, completing or delivering a game, register the requested visual/gameplay requirements with `agc_register_delivery_contract`. Interpret intent from the user’s request. No contract is needed to permit ordinary file writes, commands, generation or validation. Artifact and command-return requirements are not supported. New Web contracts retain the existing visual/gameplay minimums shown in the registration result. Trusted browser evidence remains authoritative. Status queries and operation completion do not seal the turn; automatic delivery review follows a normally completed response, with required work settled before final delivery.

 Validation is layered: visual checks do not prove gameplay, and a bounded fixed scenario does not prove an unobserved full level. Browser and hosted external checks must not be evaded by switching tools. Reuse successful evidence for unchanged inputs; a blocking defect justifies only its affected validation layer. Once all required evidence exists, deliver. Optional polish is follow-up work, not another mandatory production cycle.

 ## Workflow

-Before the first mutation or command, register the bounded required scope with `agc_register_delivery_contract`; ordinary read-only diagnosis needs no contract. Declare actual artifact, command, visual or fixed gameplay requirements. Use `agc_run_validation` with `purpose=build` for the declared `npm run build`, then the affected validation layer. When the turn is completed, exhausted, or interrupted, stop; do not expand scope or continue through another tool.
+When the user asks you to make, complete or deliver a game, register the bounded visual/gameplay requirements with `agc_register_delivery_contract`. Interpret the user’s request. Ordinary file writes, commands, image generation and validation can proceed without registration. Build and test as needed using the available tools, then run the relevant browser checks; artifact and command-return requirements are not supported. Status checks do not stop execution; automatic contract review follows normal response completion. When the turn is completed, exhausted or interrupted, stop new operations.

 Make targeted source changes with `agc_apply_patch` using the official patch syntax. Use `agc_update_plan` for a multi-step task's progress. Independent edits, reads, plan updates and resource calls may run in parallel; wait for earlier edits to the same file and for dependencies needed by builds or validation. A failed patch may have partially changed the project, so read the current files before constructing a new patch. Stop on timeout, cancellation or `needsReconciliation=true`. For a complete text-file replacement, `agc_write_file` accepts the original UTF-8 body.
