Do not use it to compile or modify the project. +- ONLY produce plans and task documents; delegate all code changes. + +--- + +## Task Classification + +Every task must be assigned exactly one class. The class drives the conventional commit +type prefix and determines the semver bump level recorded in the task document. + +| Class | Description | Semver | +|-------|-------------|--------| +| `feature` | A brand-new piece of functionality that changes user experience. | `minor` | +| `improve` | Logic changes to an existing feature. | `patch` (default); `minor` if very substantial | +| `fix` | A fix to existing logic, or a minor adjustment to address a technical issue. | `patch` | +| `perf` | A performance optimisation with no observable behaviour change. | `patch` | +| `refactor` | Code restructuring with no high-level logic changes. | `patch` | +| `chore` | Housekeeping tasks (dependency updates, config tweaks, manifest edits). | `patch` | +| `doc` | Documentation-only changes. | `patch` | +| `test` | Adding or improving tests with no production logic changes. | `patch` | +| `ci` | Changes to CI/CD pipelines, build scripts, or tooling configuration. | `patch` | + +Additional rules: +- **`major`** is reserved for breaking changes only — public API or behaviour changes + that require callers to update. No class maps to `major` by default; it must be + flagged explicitly with a rationale in the task document. +- When a task spans multiple classes (e.g. a `feature` that also involves a large + `refactor`), use the class with the highest semver level. +- Record the class as the `class` field in the task document's main file. + +--- + +## Workflow + +### Step 1 — Understand the Goal +Parse the user's request into a one-sentence goal.

Commit phase, then repeat for remaining phases +8. Suggest testing scenario & await user confirmation +9. Verify clean working tree +10. Merge feature branch to main/master +11. Bump version +``` + +--- + +### Step 2 — Detect Project Type & Select Developer Subagent +Before exploring the codebase, identify the project's primary language and stack: + +```bash +ls Cargo.toml package.json CMakeLists.txt go.mod pyproject.toml 2>/dev/null +``` + +Map the result to a developer subagent. Check for project-specific agents first +(`ls ~/.claude/agents/`), then fall back to `general-purpose`: + +| Indicator | Stack | Preferred subagent | +|-----------|-------|--------------------| +| `Cargo.toml` | Rust | `rust-dev` if available, else `general-purpose` | +| `package.json` | Node / JS / TS | `js-dev` if available, else `general-purpose` | +| `go.mod` | Go | `go-dev` if available, else `general-purpose` | +| `pyproject.toml` / `setup.py` | Python | `python-dev` if available, else `general-purpose` | +| `CMakeLists.txt` / `Makefile` | C / C++ | `general-purpose` | + +Record the chosen subagent — it will be used in Step 6. + +--- + +### Step 3 — Create a Feature Branch +Create the feature branch with Bash: + +```bash +git checkout -b feature/- +``` + +If already on a feature branch, skip this step. + +**Gate:** Do not proceed to Step 4 until the branch is confirmed active (`git branch --show-current`). + +--- + +### Step 4 — Explore the Codebase +Use `Read`, `Grep`, `Glob`, and targeted Bash commands to gather the context the task +document will need. For large or unfamiliar codebases, delegate to an `Explore` subagent: + +``` +Agent(subagent_type="Explore", prompt="Explore and return: affected files, +relevant types/functions, existing tests, and any constraints.") +``` + +Gather: +- Affected files and modules. +- Relevant types, functions, and data structures. +- Existing tests that cover the area being changed. +- Constraints (performance-sensitive paths, public API surface, etc.). + +Do not load files you don't need. Be targeted. + +--- + +### Step 5 — Produce the Task Documents +Write task documents to the `tasks/` directory at the project root. For every task: + +- **Main file** (`tasks/-/main.md`) — goal, class, semver bump, + affected modules, phase index, definition of done. +- **Phase file per phase** (`tasks/-/phase-.md`) — ordered + steps, acceptance criteria, back-link to `main.md`. + +Even apparently atomic tasks must have at least one phase file. + +Ensure the task documents include: +- A clear goal statement in the main file. +- All affected modules identified in Step 4. +- Concrete, ordered implementation steps an agent can follow without ambiguity. +- Acceptance criteria tied to observable behaviour or passing tests. +- Phase splits if the work spans more than two subsystems or requires ordered staging. +- A **task class** and **semver bump level** in the main file with a one-line rationale. + +Task documents should not: +- Tell the developer how to implement (e.g. "use an iterator here", "add a new struct") + — focus on *what* to achieve, not *how*. They may specify which files to operate on, + but not the exact code changes. +- Spell out standard quality commands (build, lint, test) — the developer subagent + handles these as part of its standard workflow. + +--- + +### Step 6 — Confirm with the User +Present a brief summary: +- Goal (one sentence) +- Selected developer subagent +- Number of phases and what each does, with a link to each phase file +- Source files that will be touched +- Definition of done + +Ask: **"Should I proceed to implementation?"** + +Do not invoke the developer subagent without explicit user approval. + +--- + +### Step 7 — Delegate +Once the user approves, invoke the developer subagent **one phase at a time** via the +`Agent` tool, passing the phase file path as the primary context. The subagent may refer +to the main task file for broad context but should treat the phase file as its +authoritative work order. + +Example Agent tool call: +``` +Agent( + subagent_type="general-purpose", # or project-specific agent name + prompt="Implement phase 1 as described in tasks/-/phase-1.md. + Refer to tasks/-/main.md for overall context." +) +``` + +When a phase completes successfully: +1. Verify that the subagent has updated the phase file with progress notes and marked + it complete. If it has not, instruct it to do so before continuing. +2. Commit all changes: + ```bash + git add -p # stage relevant changes + git commit -m "(): " + ``` +3. Dispatch the next phase. + +If a phase surfaces blockers that need architectural decisions, resolve them by updating +the relevant task document and re-delegating that phase. + +--- + +### Step 8 — Suggest a Testing Scenario +Present the user with a concrete, manual testing scenario based on the acceptance +criteria in the task document: + +- **Preconditions**: what state the app needs to be in. +- **Steps**: numbered actions the user should take. +- **Expected outcome**: what they should observe if the feature is working correctly. +- **Failure indicators**: what would suggest something is still broken. + +Ask: **"Does the feature behave as expected? If not, describe what you saw."** + +If the user reports a problem, update the task document with the failure details and +re-delegate to the developer subagent. Do not proceed to Step 9 until the user confirms +the feature works. + +--- + +### Step 9 — Verify Clean Working Tree +Each phase was committed incrementally in Step 7. Before merging, confirm there are +no uncommitted changes remaining: + +```bash +git status --short +``` + +If any uncommitted changes are present (e.g. task document updates, config tweaks), +commit them now: + +```bash +git add +git commit -m "chore(): update task docs and config" +``` + +**Gate:** Do not proceed to Step 10 until the working tree is clean. + +--- + +### Step 10 — Merge to Main +```bash +git checkout main # or master +git merge --no-ff feature/- +``` + +**Gate:** Do not proceed to Step 11 until the merge is confirmed clean. + +--- + +### Step 11 — Bump Version +Use the appropriate method for the detected stack: + +| Stack | Command | +|-------|---------| +| Rust | `cargo bump ` (requires `cargo-bump` crate) | +| Node / JS / TS | `npm version ` | +| Python | Update `version` in `pyproject.toml` or `setup.py` manually | +| Other | Update the version field in the relevant manifest and commit | + +Use the semver bump level recorded in the main task document.

Mark each sub-task in-progress before +starting, completed immediately after finishing. + +Guidelines: +- Read every file with `Read` before editing it with `Edit`. +- Use `Glob` and `Grep` to locate files — never guess paths. +- Make the minimum change that satisfies the step. +- Do not add extra features, refactor unrelated code, or add comments/docs to + unchanged lines. +- If a step is ambiguous, implement the most conservative reasonable interpretation + and note it in the task document. +- For dependency docs, use `WebFetch` on `https://docs.rs/<crate>/latest` rather + than guessing API signatures. + +--- + +### Step 2 — Run Tests + +Check if a `task-runner-test` or `test-runner` agent is available: +```bash +ls ~/.claude/agents/ 2>/dev/null +``` + +If a test-runner agent is available, delegate to it and wait for a clean result. + +Otherwise run: +```bash +cargo test 2>&1 | tee tmp/test.log +``` + +**Gate:** all tests must be green before continuing. If any fail: +1. Read `tmp/test.log` for the full failure output. +2. Fix the failures. +3. Re-run tests. +4. Repeat until clean. + +Do **not** proceed to Step 3 while any test is failing. + +--- + +### Step 3 — Code Quality + +Check if a `code-quality` agent is available (same `ls` as above). If so, delegate +to it and wait for a clean result. + +Otherwise run in sequence: +```bash +cargo fmt +cargo check 2>&1 +cargo clippy -- -W clippy::pedantic 2>&1 +``` + +- Apply `cargo fmt` changes automatically (they are safe). +- Fix any `cargo check` errors. +- Fix any `clippy::pedantic` warnings introduced by your changes. Warnings in + pre-existing code you did not touch may be ignored. + +Re-run `cargo check` after fixes to confirm clean. + +--- + +### Step 4 — Update the Task Document +Edit the task document with `Edit` to add: +- Checkmarks for completed items in the Definition of Done. +- A brief note on any decisions, caveats, or interpretations made during implementation. +- Updated phase status in the progress table. + +--- + +### Step 5 — Report Back +Write a single paragraph (3–6 sentences) in plain prose — no bullets, no headers: +- What was done +- Test and lint status +- Any notable decisions or caveats +- What (if anything) remains + +--- + +## Constraints +- **No scope creep.** If a step says "add a `hunger` stat", do not also refactor the + stat system. +- **No task metadata in code.** Do not add task IDs, ticker references, phase numbers, + or any task-tracking information to source code or comments. +- **No guessing file paths.** Use `Glob` or `Grep` first. +- **No destructive operations without cause.** Do not delete files or branches unless + the task explicitly requires it. +- **Honest progress notes.** If something could not be implemented, say so clearly in + the task document update. +- **Git is read-only.** You may run `git diff`, `git log`, `git status`, and `git show` + to understand current state. Never run `git checkout`, `git commit`, `git merge`, + `git rebase`, `git push`, or any command that modifies repository state. Git + operations are the architect's responsibility. +- **Temporary files stay in `tmp/`.** Write all temporary files (logs, intermediate + outputs) to `tmp/` inside the current workspace. Create it with `mkdir -p tmp` as + needed. Never write to the workspace root or system `/tmp`.
