# Audit / fieldtest / docwriter cadence restructure — Implementation Plan
> **Parent spec:** `docs/specs/2026-05-11-audit-fieldtest-docwriter-cadence.md`
>
> **For agentic workers:** REQUIRED SUB-SKILL: use `skills/implement` to run this plan. Steps use `- [ ]` checkboxes for tracking.
**Goal:** Move docwriter into its own Boss-dispatched skill; shrink audit to architect+bencher; sharpen fieldtest framing as Boss-dispatched post-audit Praxistest; refresh `skills/README.md` cadence taxonomy.
**Architecture:** Pure config/docs reshuffle, no code. Three Boss-orchestrated buckets: per-milestone-mandatory (audit), Boss-judgment post-audit (fieldtest), Boss-judgment post-fieldtest (docwriter). The sequence forms `audit → (Boss: ready?) → fieldtest → (Boss: stable?) → docwriter`.
**Tech Stack:** Markdown only. Files under `skills/` and `.claude/`.
---
## Files this plan creates or modifies
- **Create:** `skills/docwriter/SKILL.md` — short SKILL.md pointing at the agent's own carrier contract; Boss-dispatched trigger criteria; no mandatory schedule.
- **Create:** `.claude/skills/docwriter` (symlink → `../../skills/docwriter`).
- **Create:** `.claude/agents/docwriter` (symlink → `../../skills/docwriter/agents`).
- **Modify:** `skills/audit/SKILL.md` — drop Step 3, drop docwriter from agents-dispatched, drop the rustdoc Common-Rationalisation row, update cross-references.
- **Modify:** `skills/fieldtest/SKILL.md` — sharpen trigger to Boss-dispatched; name the expected finding-shape (simple bugs or catastrophic architecture problems).
- **Modify:** `skills/README.md` — skill table: refine audit row, add docwriter row, refine fieldtest row; pipeline diagram extended with the late `→ docwriter` branch; agent roster moves `ailang-docwriter` into a new docwriter group.
Already-present (no action): `skills/docwriter/agents/ailang-docwriter.md` (user-moved from `skills/audit/agents/`).
---
## Task 1 — Create `skills/docwriter/SKILL.md` + symlinks
**Files:**
- Create: `skills/docwriter/SKILL.md`
- Create: `.claude/skills/docwriter` (symlink)
- Create: `.claude/agents/docwriter` (symlink)
- [ ] **Step 1: Write `skills/docwriter/SKILL.md`** with the structure below (frontmatter + body). Length target ≤ 90 lines.
Frontmatter:
```yaml
---
name: docwriter
description: Use when the API surface of one or more crates has stabilized across recent milestones and rustdoc lag is suspected (cargo doc --no-deps shows accumulated warnings, or a newcomer would not be able to navigate the crate from `cargo doc --open` without DESIGN.md). NOT a per-milestone step; Boss-dispatched only, after audit closes clean and after any pending fieldtest has run.
---
```
Body must cover, in order:
1. `> Violating the letter of these rules is violating the spirit.` lead-in.
2. **Overview** — one paragraph naming the cadence question this skill answers: rustdoc rot accumulates silently; documenting unstable code is waste; the right moment is post-stability. Reference the cadence taxonomy (3 buckets) without re-explaining it.
3. **When to Use / Skipping** — Boss-dispatched only. Trigger conditions: (a) `cargo doc --no-deps` shows accumulated warnings across multiple crates after a stability window, (b) a roadmap entry like "Rustdoc warning sweep" has matured, (c) onboarding-readability check. Explicitly: NOT triggered by audit closing.
4. **The Iron Law** — code-fenced:
```
DOCWRITER IS POST-STABILITY, NOT PER-MILESTONE.
NO API CHANGES — DOCS ONLY.
IF THE CODE STILL FEELS LIKE IT MIGHT GET REWRITTEN, DON'T DOCUMENT IT YET.
```
5. **Dispatch** — one paragraph: orchestrator dispatches `ailang-docwriter` with `crate_scope`, `warning_target`, optional `priority_items`. The agent carries the rules; this SKILL.md only governs trigger + dispatch.
6. **Handoff Contract** — table mirroring the agent's carrier (crate_scope, warning_target, priority_items as in / Status, files_touched, warnings_cleared, findings as out).
7. **Cross-references** — point at `skills/docwriter/agents/ailang-docwriter.md` for the substantive process; point at `skills/audit/SKILL.md` (the pre-condition: audit must have closed clean) and `skills/fieldtest/SKILL.md` (run any pending fieldtest first).
- [ ] **Step 2: Create the symlinks**
```bash
ln -s ../../skills/docwriter .claude/skills/docwriter
ln -s ../../skills/docwriter/agents .claude/agents/docwriter
ls -la .claude/skills/docwriter .claude/agents/docwriter
```
Expected output: both `lrwxrwxrwx` lines pointing at the right targets.
- [ ] **Step 3: Commit**
```bash
git add skills/docwriter/SKILL.md .claude/skills/docwriter .claude/agents/docwriter
git commit -m "iter cadence.1: skills/docwriter — new Boss-dispatched skill (split from audit)"
```
---
## Task 2 — Shrink `skills/audit/SKILL.md`
**Files:**
- Modify: `skills/audit/SKILL.md`
- [ ] **Step 1: Remove Step 3** ("Optional rustdoc audit") entirely. Renumber Step 4 → Step 3, Step 5 → Step 4.
- [ ] **Step 2: Update "Combine architect drift items + bench results + rustdoc warnings"** in the (now-Step-3) Classify-and-report paragraph: drop the `+ rustdoc warnings` clause. The classification stays `fix / ratify / carry-on`.
- [ ] **Step 3: Update the Handoff Contract table** — remove the `rustdoc_warnings` row.
- [ ] **Step 4: Remove the Common-Rationalisation row** "Rustdoc warnings are just style, no real drift".
- [ ] **Step 5: Update "Agents dispatched" cross-references** — remove the `skills/audit/agents/ailang-docwriter.md` bullet entirely. The architect and bencher bullets remain.
- [ ] **Step 6: Update the "Project source" cross-reference** if it names rustdoc — re-read the paragraph and decide. Current wording mentions "Iter cycle / Tidy-iter at family boundaries" and "Performance regressions"; if neither names rustdoc, leave the paragraph as-is.
- [ ] **Step 7: Sanity-grep**
```bash
git grep -n "docwriter\|rustdoc" skills/audit/SKILL.md
```
Expected: no matches.
- [ ] **Step 8: Commit**
```bash
git add skills/audit/SKILL.md
git commit -m "iter cadence.2: skills/audit — drop docwriter step (now own skill)"
```
---
## Task 3 — Sharpen `skills/fieldtest/SKILL.md`
**Files:**
- Modify: `skills/fieldtest/SKILL.md`
- [ ] **Step 1: Rewrite the "When to Use / Skipping" trigger section** to frame fieldtest as a Boss-dispatched Praxistest. Replace the current "Triggers:" bullet "A milestone has just closed `audit` cleanly (or with `ratify`-d drift only)." with:
> Boss-dispatched after audit closes cleanly, when the orchestrator believes the iteration is correct and wants a Praxistest. The pre-condition is a clean (or `ratify`-d) audit; the trigger is the Boss's judgment-call that the iteration is fertig.
Keep the other two trigger bullets ("A shipped feature is suspected of being LLM-hostile…" / "A user-facing surface change…") — they already match Boss-judgment.
- [ ] **Step 2: Add a one-line note on expected finding shape**, immediately after the trigger bullets. Wording:
> Findings cluster around two shapes — simple bugs (route via `debug` → `implement` mini) or catastrophic architecture problems (route via next `brainstorm`). Friction and spec-gap items are also possible; the routing table below applies in all cases.
- [ ] **Step 3: Add an explicit ordering note** in the Cross-references or Overview section: fieldtest runs **before** docwriter; docwriter happens at a later, longer stability window. One line is enough.
- [ ] **Step 4: Sanity-check** the rest of the document — Iron Law, Process, Handoff Contract, Common Rationalisations should remain unchanged. The Boss-judgment framing is the only conceptual shift.
- [ ] **Step 5: Commit**
```bash
git add skills/fieldtest/SKILL.md
git commit -m "iter cadence.3: skills/fieldtest — Boss-dispatched framing + ordering note"
```
---
## Task 4 — Refresh `skills/README.md` cadence taxonomy
**Files:**
- Modify: `skills/README.md`
- [ ] **Step 1: Update the skill table** ("The six skills" — note it's now seven; rename the section heading if appropriate).
- audit row's `Output` and `Mandatory?` are correct; refine the description if it implies rustdoc. The audit description should mirror its frontmatter: "Architect drift review + three regression scripts."
- Insert a new row for **docwriter** between `audit` and `fieldtest`:
- Trigger: "API surface stabilized; rustdoc lag suspected"
- Output: "rustdoc updates in `///` and `//!`"
- Mandatory?: "No — Boss-dispatched only"
- fieldtest row description should explicitly say "Boss-dispatched post-audit Praxistest", not "after audit closes".
- Bump the heading from "The six skills" to "The seven skills".
- [ ] **Step 2: Update the pipeline diagram** to reflect the new sequence:
```
[new milestone] [bug observed]
| |
v v
brainstorm -> plan -> implement debug -> implement (mini)
(per iteration loop)
|
[milestone close]
|
v
audit --(drift)--> plan + implement (tidy iteration)
--(ratify)-> JOURNAL + --update-baseline
--(clean)-+
|
[Boss: iter fertig? if surface-touch:]
v
fieldtest --(bug)------> debug -> implement (mini)
--(friction)-> brainstorm OR plan (tidy)
--(spec_gap)-> ratify OR tighten DESIGN.md
--(clean)----+
|
[Boss: surface stable across N milestones?]
v
docwriter (rustdoc sweep)
|
v
next milestone
```
(Keep the existing ASCII style; the diagram above is the target shape.)
- [ ] **Step 3: Update the agent roster table** — move the `ailang-docwriter` row out of the `audit` group into a new docwriter group (its `Path` becomes `docwriter/agents/`; `Dispatched by skill` becomes `docwriter`).
- [ ] **Step 4: Discovery section** — bump the symlink list under "Skills are reachable" and "Agents are reachable" to include docwriter (the symlinks were created in Task 1).
- [ ] **Step 5: Commit**
```bash
git add skills/README.md
git commit -m "iter cadence.4: skills/README — three-bucket cadence taxonomy"
```
---
## Task 5 — Final cross-ref verification
**Files:**
- No new edits expected. Verification only; if a grep hits an orphan, fix inline.
- [ ] **Step 1: Grep for orphaned docwriter references in audit**
```bash
git grep -n "docwriter\|rustdoc" skills/audit/SKILL.md
```
Expected: zero hits.
- [ ] **Step 2: Grep CLAUDE.md for docwriter wiring**
```bash
git grep -n "docwriter" CLAUDE.md
```
If hits exist, evaluate whether the wording still applies under the new packaging. If not, fix inline.
- [ ] **Step 3: Grep the symlinks**
```bash
ls -la .claude/skills/docwriter .claude/agents/docwriter
test -L .claude/skills/docwriter && test -L .claude/agents/docwriter && echo OK
```
Expected: both symlinks present, "OK" printed.
- [ ] **Step 4: Final read-through**
Read `skills/audit/SKILL.md`, `skills/fieldtest/SKILL.md`, `skills/docwriter/SKILL.md`, and `skills/README.md` end-to-end. Confirm:
- audit no longer mentions docwriter
- fieldtest's trigger reads as Boss-dispatched
- docwriter's SKILL.md is reachable and complete
- README's skill table and pipeline diagram match the three-bucket cadence
- [ ] **Step 5: Per-iter journal**
Append `docs/journals/2026-05-11-iter-cadence.md` mirroring the per-iter journal style (or.1, fieldtest entries are templates). Include: per-task subjects, summary of the three-bucket cadence, one-line lesson on packaging cadence by stability-window rather than milestone-grain.
Update `docs/journals/INDEX.md` with one new line.
- [ ] **Step 6: Commit**
```bash
git add docs/journals/2026-05-11-iter-cadence.md docs/journals/INDEX.md
git commit -m "iter cadence.5: per-iter journal + INDEX"
```
---
## Acceptance check (run at end)
```bash
git grep -nE "Step 3 — Optional rustdoc" skills/ # zero hits
git grep -nE "ailang-docwriter" skills/audit/ # zero hits
ls -la .claude/skills/docwriter .claude/agents/docwriter # both symlinks
```
All three expectations green → iter cadence is done.

# Audit / fieldtest / docwriter cadence restructure — 2026-05-11
**Status:** Approved (orchestrator + user, chat-derived)
**Scope:** skill-system reshuffle; no code touched
## Motivation
Today `audit/SKILL.md` bundles three checks under one milestone-close
trigger:
1. **architect** drift review
2. **bencher** regression check
3. **docwriter** rustdoc cleanup (Step 3, "optional")
Fieldtest is a separate skill but is described as following audit by
default for any milestone that touched user-visible surface.
The trio mixes three different cadence-needs:
- **drift** and **regression** are intrinsic to a milestone close —
they compound silently across milestones if deferred, so they
*must* run at every close.
- **fieldtest** measures usability-belief — it's a Praxistest run when
the orchestrator believes the iteration is correct. Findings are
either simple bugs or catastrophic architecture problems; both
decay slowly, so the cadence doesn't have to be per-milestone.
- **docwriter** documents stable API surface. Writing rustdoc onto
code that the next iteration may rewrite is wasted work. The right
cadence is *post-stability*, not *per-milestone*.
The current packaging forces these three different cadences into one
mandatory pipeline step. This spec splits them.
## Decision
Three Boss-orchestrated buckets:
1. **Per-milestone, mandatory (audit)**: architect + bencher only.
2. **Boss-judgment, post-audit, "the iter is fertig"**: fieldtest.
3. **Boss-judgment, post-fieldtest, "API surface has settled"**:
docwriter.
Sequence: `audit → (Boss: ready?) → fieldtest → (Boss: stable?) →
docwriter`. The two Boss-gated steps share the same "don't produce
output for code that may still be rewritten" principle; their
stability windows differ (iter-stable vs. surface-stable).
## Concrete changes
### docwriter becomes its own skill
- Create `skills/docwriter/SKILL.md` (new).
- `skills/docwriter/agents/ailang-docwriter.md` already exists
(moved by user from `skills/audit/agents/`).
- Frontmatter description: "Use when API surface has stabilized
across one or more milestones and rustdoc lag is suspected. NOT a
per-milestone step; Boss-dispatched only."
- The SKILL.md body is short — mostly a pointer to the agent's own
carrier contract plus the trigger criteria. No mandatory schedule.
- Symlinks: add `.claude/skills/docwriter → ../../skills/docwriter`
and `.claude/agents/docwriter → ../../skills/docwriter/agents`.
### audit shrinks
- `skills/audit/SKILL.md`: remove "Step 3 — Optional rustdoc audit".
- Remove `ailang-docwriter` from the "Agents dispatched" list.
- Remove the "Rustdoc warnings are just style" row from Common
Rationalisations.
- Frontmatter description: now reads "architect drift review +
three regression scripts" — already correct since the
user-applied tweak.
### fieldtest framing sharpened
- `skills/fieldtest/SKILL.md`: trigger section reframes from "after
audit closes cleanly" (which sounded automatic) to "Boss-dispatched
after audit closes cleanly, when the orchestrator believes the
iteration is correct and wants a Praxistest". The pre-condition is
still a clean audit; the trigger is the Boss's judgment-call.
- Add a one-line note on what kind of findings to expect: either
simple bugs (→ debug → implement mini) or catastrophic
architecture problems (→ next brainstorm). Friction items are
also possible; the routing table stays.
### skills/README.md updated
- Skill table: change audit row's description; add docwriter row;
refine fieldtest row to mention Boss-dispatch explicitly.
- Agent roster: move `ailang-docwriter` from the audit group to a
new docwriter group.
- Pipeline diagram: extend with the late `→ (Boss judgment) →
docwriter` branch.
### CLAUDE.md cross-ref check
- `Roles of docs/...` table mentions audit / journals / specs /
plans / WhatsNew — does not name docwriter or rustdoc
scheduling. No edit needed.
- Skill system overview: see if docwriter is mentioned. If yes,
refresh the wording. If no, no edit.
## Out of scope
- Any change to the agents' own behaviour (architect, bencher,
fieldtester, docwriter agent files).
- Code changes. This is a config/docs restructure only.
- The `Rustdoc warning sweep` P2 roadmap item — it stays where it
is; in fact this restructure makes it the canonical example of
"Boss-dispatched docwriter".
## Acceptance
- `skills/docwriter/SKILL.md` exists and is reachable via
`.claude/skills/docwriter`.
- `skills/audit/SKILL.md` no longer mentions docwriter or Step 3.
- `skills/fieldtest/SKILL.md` describes Boss-dispatch trigger
language.
- `skills/README.md` reflects the new three-bucket cadence.
- `git grep -n "Step 3 — Optional rustdoc"` in `skills/` returns
nothing.
- `git grep -n "docwriter" docs/CLAUDE.md skills/README.md
skills/audit/SKILL.md skills/fieldtest/SKILL.md` only matches
the new wording, not orphans from the old packaging.
