Nothing is declared done until all tests pass. **Orchestrator**: `build` agent — this workflow is always started and driven by the `build` agent. The build agent reads the plan, decomposes work, delegates to coders, escalates to consultants when blocked, and closes the workflow. **Prerequisite**: A plan file must exist in `.opencode/plans/`. Read it carefully and thoroughly before doing anything else. Every decision must trace back to the plan. Do not improvise, skip, or reinterpret scope. --- ## Step 1 — Start as the Build Agent This workflow is owned by the `build` agent from start to finish. The build agent does not write code — it orchestrates. Its responsibilities are: - Read and deeply understand the plan in `.opencode/plans/` - Decompose the plan into atomic implementation tasks - Delegate tasks to `developer-prime` and `developer-fast` - Escalate to consultants the moment anything is unclear, blocked, or risky - Verify quality gates and ensure all tests pass before closing **Do not skip this agent assignment.** The build agent is the single point of accountability for the entire workflow. --- ## Step 2 — Read the Plan Carefully and Thoroughly Locate the plan file in `.opencode/plans/`. Read it in full before taking any action. Pay close attention to: - Goals and scope - Architecture and design decisions - Implementation tasks and their dependencies - Security, performance, and database considerations - Testing strategy and acceptance criteria **Follow every instruction in the plan thoroughly.** The plan is the source of truth. If the plan says to do something a specific way, do it that way exactly. Do not improvise. If something in the plan is ambiguous, escalate to the appropriate consultant before proceeding (see Step 4). --- ## Step 3 — Decompose and Track All Tasks Break every implementation item in the plan into atomic, actionable tasks. Register all tasks in TodoWrite immediately. Rules: - Mark a task `in_progress` the moment work begins on it - Mark a task `completed` the moment it is verifiably done — do not batch - Only one task should be `in_progress` at a time - Never declare a task complete without evidence (tests pass, code reviewed) --- ## Step 4 — Delegate to Coders Assign implementation tasks to the appropriate coder agent and run independent tasks in parallel: | Task type | Assigned agent | |---|---| | Complex, multi-file, or long-context work | `developer-prime` | | Scoped, single-file, boilerplate, or high-volume tasks | `developer-fast` | Run all independent tasks simultaneously. Never serialise work that can be parallelised. ### Load Language Skills Before Delegating Before dispatching each task, load the skill matching the target technology so the coder agent inherits the correct style conventions: | Technology | Skill | |---|---| | TypeScript / TSX | `typescript-style` | | JavaScript / JSX | `javascript` | | Python | `python` | | Go | `go` | | CSS | `css` | | HTML | `html` | | Tailwind | `tailwind-css` | ### Task Prompt Template Give every coder agent a fully-formed prompt — never a vague description: ``` Task: Context: Requirements: - - Files to modify: - Files to create: - Architectural guidance: Security requirements: Database guidance: Success criteria: - - ``` ### Per-Task Verification After each coder agent completes a task, verify before marking it done: 1. Run the relevant tests (`npm test` / `pytest` / `go test ./...`) 2. Check type errors (`tsc --noEmit` / `mypy` / `go vet`) 3. Run linter / formatter 4. Confirm expected behaviour 5. Mark the todo `completed` **immediately** — do not batch Never advance to the next task while the current one has a failing check. --- ## Step 5 — Consult Immediately When Blocked or Uncertain If anything goes wrong, gets stuck, requires a decision not covered by the plan, or carries architectural/security/data risk — **stop and consult before continuing**. Do not guess. Do not proceed on assumptions. Escalate to the relevant consultant(s) immediately and in parallel if multiple perspectives are needed: | Situation | Consult | |---|---| | Architecture or system design question | `principal-architect` | | Service design or cross-component decision | `solution-architect` | | Data model, schema, or query concern | `database-architect` | | Security, auth, or threat modelling concern | `security-expert` | Consultants operate in **Think → Advise → Review** mode: they analyse the situation, give a concrete recommendation, and review the outcome. Their guidance must be incorporated before work continues. **Consultation is not optional when blocked.** It is a required part of the workflow. --- ## Step 6 — Quality Gates After all coding tasks complete, run the following reviews **in parallel** before declaring the implementation done: - `security-expert` — verify all security mitigations from the plan are correctly implemented - `principal-architect` — verify the implementation matches the agreed design - `solution-architect` — verify service boundaries and interfaces are correct - `database-architect` — verify schema, migrations, and queries are sound Address every finding before moving to testing. --- ## Step 7 — Testing and Validation Run the project's full test suite. If tests are missing for new code, delegate to `developer-fast` to add them per the testing strategy defined in the plan. All tests must pass before the workflow closes. No exceptions. --- ## Step 8 — Documentation and Git Review Before presenting the final summary, do a clean-up pass: 1. **Update code documentation** — add JSDoc / docstrings to all new public APIs; add inline comments for non-obvious logic. 2. **Update README** if the feature requires new setup steps, environment variables, or changed behaviour. 3. **Update `.env.example`** for any new environment variables introduced. 4. **Remove all debug artefacts** — no `console.log`, no commented-out code, no temporary files. 5. **Run `git status` and `git diff --stat`** to confirm only intended files changed and no unintended modifications are included. --- ## Step 9 — Final Summary Present a concise summary covering: - What was built - Which agents contributed - Tasks completed (count) - Files changed (count, added vs modified) - Test results (passing / total, coverage if available) - Any deviations from the original plan and their justifications - Warnings or post-deployment considerations (migrations, env vars, etc.) - Suggested next steps (review `git diff`, commit, open PR, deploy) --- ## Key Rules - **Build agent owns the workflow.** This workflow starts and ends with the build agent. - **Read the plan carefully and thoroughly.** Every action must trace to the plan. - **Follow instructions thoroughly.** Do exactly what the plan specifies. Do not reinterpret or skip steps. - **Load language skills before delegating.** Give coders the right style context. - **Use the task prompt template.** Never delegate with a vague description — include task, context, files, consultation outputs, and success criteria. - **Verify each task before moving on.** Run tests, type-check, and lint after every task. Do not accumulate failures. - **Delegate to developer-prime and developer-fast.** These are the two coder agents in this workflow. - **Consult immediately when blocked.** principal-architect, solution-architect, database-architect, and security-expert are on call for Think → Advise → Review. - **Parallel by default.** Never run independent tasks or consultations sequentially. - **Track every task.** Use TodoWrite throughout. No task is done until marked completed. - **Quality gates are mandatory.** Do not skip the parallel review step before testing. - **All tests must pass.** Do not close the workflow with failing tests. - **Clean up before closing.** Update docs, remove debug code, verify git status before the final summary. --- ## Agent Roster ### Orchestrator | Agent | Role | |---|---| | `build` | Workflow owner — reads plan, delegates, escalates, closes | ### Implementers (write code) | Agent | Specialty | |---|---| | `developer-prime` | Complex, multi-file, long-context, and frontend tasks | | `developer-fast` | Scoped, single-file, boilerplate, and high-volume tasks | ### Consultants (Think → Advise → Review — read-only, no code changes) | Agent | Specialty | |---|---| | `principal-architect` | High-level system strategy, cross-service architecture, technical governance | | `solution-architect` | Concrete service designs, cross-component interfaces | | `database-architect` | Data modelling, schema, query optimisation, migrations | | `security-expert` | Threat modelling, cryptography, auth, secure coding | --- ## Workflow at a Glance ``` Build agent starts │ ▼ Read plan from .opencode/plans/.md (carefully and thoroughly) │ ▼ Decompose into atomic tasks (TodoWrite) │ ▼ For each task: Load language skill → build task prompt → delegate ├── developer-prime (complex / multi-file) └── developer-fast (scoped / single-file) │ ▼ (after each task) Per-task verification: tests → type-check → lint → mark completed │ ▼ (if blocked or uncertain at any point) Consult immediately (in parallel as needed) ├── principal-architect → Think, Advise, Review ├── solution-architect → Think, Advise, Review ├── database-architect → Think, Advise, Review └── security-expert → Think, Advise, Review │ ▼ Parallel quality gates ├── security-expert ├── principal-architect ├── solution-architect └── database-architect │ ▼ Testing and validation (all tests must pass) │ ▼ Documentation update + git status review │ ▼ Final summary (tasks, files, tests, deviations, next steps) ```
