Brummel 0b969838c0 refactor: single-source carrier/handoff contracts across skills
Apply the debug-skill pattern (commits 6410732..de42974) to the
remaining skills: the agent file is the single source for each
interface field's semantics; the SKILL.md copy is reduced to field
names plus a pointer, marking the agent's contract table
authoritative. Because SKILL.md loads into orchestrator context and
agents/*.md into the subagent's fresh system prompt with no
transclusion, duplicated field tables drift apart over time.

- brainstorm: carrier (spec_path/iteration_scope) -> grounding-check;
  the absolute-path requirement now lives only in the agent.
- planner: carrier (spec_path/iteration_scope/focus_hint) ->
  plan-recon, including the mandatory/optional markers and the
  BLOCKED-on-missing rule SKILL.md had omitted.
- fieldtest: carrier + produced fields -> fieldtester; the skill-level
  `status` roll-up (clean/friction_found/bugs_found/infra_blocked),
  which is not part of the agent's run-status protocol, stays defined
  in SKILL.md only.
- docwriter: carrier + produced fields -> docwriter agent.
- implement: carrier (iter_id scratch-dir/stats/not-a-branch
  semantics) -> implement-orchestrator; per-task sub-status vocabulary
  moved into the orchestrator-agent (it runs the loop in a fresh
  context and could not read SKILL.md at runtime, yet referenced "the
  sub-status table" by name); task_text_path single-sourced in
  implementer with spec-reviewer cross-referencing.

audit was already the reference implementation (pointers, no restated
contracts) and is unchanged.

name: docwriter
description: Use when the API surface of one or more components has stabilized across recent cycles and API-doc lag is suspected (the project's documentation tool shows accumulated warnings, or a newcomer would not be able to navigate the generated docs without the design ledger). NOT a per-cycle step; orchestrator-dispatched only, after audit closes clean and after any pending fieldtest has run.

# docwriter — post-stability documentation sweep
> **Violating the letter of these rules is violating the spirit.**
## Overview
API documentation rots silently. Every iteration changes APIs
and module boundaries; doc comments lag. Running this sweep
per-cycle is waste — documenting an item that gets renamed two
iterations later just burns context. The right moment is
post-stability: after a stretch of cycles in which the surface
in question has held still. This skill is the third bucket in
the cadence taxonomy (per-cycle-mandatory audit; orchestrator-
judgment post-audit fieldtest; orchestrator-judgment post-
fieldtest docwriter), and it fires on orchestrator judgment,
never on a cycle clock.
## When to Use / Skipping
Orchestrator-dispatched only. Audit closing **does not**
trigger docwriter. Trigger conditions are any of:
- The command configured under `commands.doc_build` in the
project profile shows accumulated warnings across multiple
components after a stability window of several cycles.
- A backlog issue like "doc warning sweep" has matured — the
surface it targets has not moved for a while.
- Onboarding-readability check: navigating the generated docs
for a component is not self-supporting without the design
ledger.
Skipping is the default. The skill only runs when the
orchestrator positively decides the surface is stable enough
to document. If the code still feels like it might get
rewritten, do not dispatch — wait.
## The Iron Law
```
DOCWRITER IS POST-STABILITY, NOT PER-CYCLE.
NO API CHANGES — DOCS ONLY.
IF THE CODE STILL FEELS LIKE IT MIGHT GET REWRITTEN, DON'T DOCUMENT IT YET.
```
## Dispatch
The orchestrator dispatches `docwriter` with `scope`,
`warning_target`, and optional `priority_items`. The agent
carries the substantive rules — what counts as top-level,
module-level, and item-level documentation in this project's
doc system; intra-doc-link conventions; the verification
triple. This SKILL.md only governs trigger and dispatch; the
agent file governs the work.
## Handoff Contract
`docwriter` consumes (from orchestrator) the carrier fields
`scope`, `warning_target`, and `priority_items`, defined
authoritatively under **Carrier contract** in `agents/docwriter.md`.
`docwriter` produces, for the orchestrator, the fields `status`,
`files_touched`, `warnings_cleared`, and `findings`, defined
authoritatively under **Output format** (with the `status` enum in
the Status protocol) in `agents/docwriter.md`.
Both contracts are single-sourced in the agent file; they are
deliberately not restated here, so the two files cannot drift.
The orchestrator decides whether findings become a follow-up
iteration; `docwriter` does not self-resolve.
## Cross-references
- **Agent dispatched:** `agents/docwriter.md` — carries the
documentation rules, hard limits, verification triple,
Common Rationalisations, and Red Flags.
- **Pre-condition (upstream):** `../audit/SKILL.md` must have
closed clean (or with ratified drift only). Docwriter does
not run on a cycle with open drift.
- **Pre-condition (upstream, conditional):**
`../fieldtest/SKILL.md` — if a fieldtest is pending for the
surface in scope, run it first. Fieldtest can surface bugs
or architecture problems that would invalidate the doc work.
- **Hand-off target:** the orchestrator. Findings flow into
the project's issue backlog as candidates for a follow-up
tidy iteration.
