# request-plan

Draft `plan/<kebab-case-feature-name>.specs.md` + `plan/<kebab-case-feature-name>.plan.md`. Depth controls agent count. `receive-plan` runs after contract/blueprint; sketch skips it entirely.
The file base name `<kebab-case-feature-name>` must be kebab-case representation of the feature description (e.g., `new-login-flow`).

## Process Flow

- **0. Infer Depth** (no prompt — see Depth Inference)
- **1. Discovery** (inline grep/glob → Context Report)
- **2. Parallel Drafting** (Ideators)
- **3. Synthesis**
- **4. Write** `plan/NAME.specs.md` + `plan/NAME.plan.md` (Status: DRAFT)
- **5. Verification** (hand off to receive-plan; sketch skips)

## Step 0: Infer Depth

No `AskUserQuestion`. Resolve in order:

1. `--depth` flag on the invocation → use it.
2. Keywords in description → `sketch`: "throwaway / rough / spike / quick note / temporary"; `blueprint`: "production / migration / rollout / breaking change / compliance / security / structural".
3. Autonomous caller (e.g., when invoked by another subagent or automation script without active user terminal attachment) without depth signal → `contract`.
4. Default → `contract`.

Announce the inferred depth and subagent count in the first line of output. Do not pause.
Subagent counts to announce:

- sketch: 0 subagents
- contract: 2 subagents (2 Ideators, 0 Synthesizers)
- blueprint: 4 subagents (3 Ideators, 1 Synthesizer)

**Done when:** inferred depth (`sketch`/`contract`/`blueprint`) and subagent count are announced in the first line of output.

## Step 1: Discovery

Main thread runs Grep/Glob inline. Produce a non-empty **Context Report**: related files, key symbols, interfaces, recent changes, constraints, scope boundaries. Ideators and main thread do not re-scan.

Wrap any user-pasted or external content in `<untrusted_context>` tags before including it in the Context Report.

**Done when:** Context Report is completed and lists related files, key symbols, interfaces, recent changes, and constraints, with external content wrapped in `<untrusted_context>`.

## Step 2: Parallel Drafting (Ideators)

Dispatch ideators in ONE message, blind to each other. Provide each with the **Context Report** from Step 1 — no codebase re-scanning.

- `contract`: 2 agents — **Conventional** lens, **Risk-First** lens.
- `blueprint`: 3 agents — **Conventional**, **Risk-First**, **Minimalist** lens.

Each ideator produces a **lightweight proposal**: a short approach summary + a numbered task list. Plain prose — the Canonical Task Block Schema is not required at draft stage (see Strict Rules).

**Done when:**

- For contract/blueprint: all ideators dispatched in ONE message (contract: 2, blueprint: 3) and each returns a lightweight proposal + numbered task list.
- For sketch: the main thread drafts and outputs the inline proposal in plain prose.

## Step 3: Synthesis

- `sketch`: Skip — Step 2 output goes directly to Step 4.
- `contract`: **Main thread** merges the 2 proposals. State what was kept and discarded from each candidate. Write the merged result using the Canonical Task Block Schema.
- `blueprint`: **1 Synthesizer agent** receives both proposals and merges them. Same rationale requirement. Writes final output in Canonical Task Block Schema.

**Done when:**

- For contract/blueprint: proposals merged into one result written in the Canonical Task Block Schema, including a documented rationale of what was kept and discarded from each candidate.
- For sketch: instantly marked done (transitions Step 2 output directly to Step 4).

## Step 4: Write

Save as `plan/<kebab-case-feature-name>.specs.md` and `plan/<kebab-case-feature-name>.plan.md` with header `Status: DRAFT`. All task entries must use the Canonical Task Block Schema. For `sketch` depth, the main thread converts the Step 2 plain prose draft into the Canonical Task Block Schema during this step.

**Done when:** the specs and plan markdown files exist on disk under the `plan/` directory with `Status: DRAFT` header and Canonical Task Block Schema task entries.

## Step 5: Verification

- `sketch`: Done — no handoff.
- `contract` / `blueprint`: Pass file paths to `receive-plan`. Include the depth so receive-plan does not default to a heavier check than necessary.

**Done when:** `sketch` ends with no handoff, or `contract`/`blueprint` file paths + depth are passed to `receive-plan`.

## Headless Fallback (REVISE from receive-plan)

Re-run synthesis only — do not re-dispatch ideators:

- `contract`: Main thread re-synthesizes with the REVISE findings added as constraints.
- `blueprint`: Re-dispatch the Synthesizer agent with the REVISE findings.

Re-submit the corrected plan to `receive-plan`. If `receive-plan` returns REVISE a second time, write a detailed error summary to the console, notify the user via a high-priority message, and stop execution (do not use AskUserQuestion).

## Canonical Task Block Schema

Required in all final `specs.md` and `plan.md` outputs; ideator proposals are exempt (see Strict Rules).

```markdown
### TASK-NNN: [Action title]

Depends on: [TASK-NNN](#task-nnn) (or comma-separated list: [TASK-001](#task-001), [TASK-002](#task-002)) or none
Files: [path/to/file.ts](path/to/file.ts) (or comma-separated list of workspace-relative paths)
Symbols: [symbolName](path/to/file.ts#L42) (or comma-separated list of workspace-relative symbol paths)
Satisfies: REQ-001, SEC-002 (comma-separated list of requirements defined in specs.md)
Action: Single specific imperative implementation action.
Validate: `[runnable shell command]`
Expected result: Observable success signal.
```

**Requirement Format (specs.md):**
All requirements in `specs.md` must be declared in the following format so they can be parsed and matched:

```markdown
#### REQ-NNN: [Short description]

Detail: [Specific requirement statement]
```

## Strict Rules

- **NO Prompt at Step 0**: depth is inferred — never pause for `AskUserQuestion`.
- **NO Re-Scan**: pass the Context Report to ideators; they must not run their own discovery.
- **NO Cross-Talk**: ideators must never see each other's proposals.
- **NO Mocked Ideators**: ideators must be distinct subagents; the main thread cannot generate/simulate candidate proposals itself.
- **NO Shell Execution**: do not run arbitrary terminal/shell commands during discovery, drafting, or synthesis.
- **NO Schema at Draft Stage**: ideators write lightweight proposals; schema is synthesis-only.
