Kjell Tore Guttormsen ab504bdf8c refactor(marketplace): split cc-architect from ultraplan-local into its own plugin
Extract `/ultra-cc-architect-local` and `/ultra-skill-author-local` plus all 7
supporting agents, the `cc-architect-catalog` skill (13 files), the
`ngram-overlap.mjs` IP-hygiene script, and the skill-factory test fixtures
from `ultraplan-local` v2.4.0 into a new `ultra-cc-architect` plugin v0.1.0.

Why: ultraplan-local had drifted into containing two distinct domains — a
universal planning pipeline (brief → research → plan → execute) and a
Claude-Code-specific architecture phase. Keeping them together forced users
to inherit an unfinished CC-feature catalog (~11 seeds) when they only
wanted the planning pipeline, and locked the catalog and the pipeline into
the same release cadence. The architect was already optional and decoupled
at the code level — only one filesystem touchpoint remained
(auto-discovery of `architecture/overview.md`), which already handles
absence gracefully.

Plugin manifests:
- ultraplan-local: 2.4.0 → 3.0.0 (description + keywords updated)
- ultra-cc-architect: new at 0.1.0 (pre-release; catalog is thin, Fase 2/3
  of skill-factory unbuilt, decision-layer empty, fallback list still
  needed)

What stays in ultraplan-local: brief/research/plan/execute commands, all
19 planning agents, security hooks, plan auto-discovery of
`architecture/overview.md` (filesystem-level contract, not code-level).

What moved (28 files via git mv, R100 — full history preserved):
- 2 commands, 8 agents, 1 skill catalog (13 files), 2 scripts, 8 fixtures

Documentation updates: plugin CLAUDE.md and README.md for both plugins,
root README.md (added ultra-cc-architect section, updated ultraplan-local
section), root CLAUDE.md (added ultra-cc-architect to repo-struktur),
marketplace.json (registered ultra-cc-architect), ultraplan-local
CHANGELOG.md (v3.0.0 entry with migration guidance).

Test verification: ngram-overlap.test.mjs passes 23/23 from new location.

Memory updated: feedback_no_architect_until_v3.md now points at the new
plugin and reframes the threshold around catalog maturity rather than an
ultraplan-local milestone.

# Changelog
All notable changes to `ultra-cc-architect` are documented here.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [0.1.0] — 2026-04-30
### Initial release — extracted from `ultraplan-local` v2.4.0
`ultra-cc-architect` is the CC-specific architecture phase pulled out of the `ultraplan-local` plugin. The split decouples the universal planning pipeline (brief → research → plan → execute) from the Claude-Code-specific feature-matching logic, so users can adopt the planning pipeline without inheriting an unfinished CC-feature catalog and skill-factory.
**Why pre-release (0.1.0):**
- Catalog is thin: 11 seed skills across 8 features, decision-layer intentionally empty.
- Skill-factory has only Fase 1 (one source → one draft, manual promotion). Fase 2 (CC-changelog watcher) and Fase 3 (cross-feature decision skills) are unbuilt.
- `feature-matcher` falls back to a hardcoded list when the catalog is sparse — this fallback should disappear before v1.0.
- Slug convention is stable but catalog-growth tooling (batch authoring, automated taxonomy updates) is not.
### Inherited from ultraplan-local v2.4.0
**Commands (2):**
- `/ultra-cc-architect-local` — feature matching with brief-anchored rationale and explicit coverage gaps. Modes: `--project` (required), `--quick` (skip critic), `--no-gaps`, `--fg` (no-op alias).
- `/ultra-skill-author-local` — skill-factory Fase 1 manual authoring. Modes: default, `--quick` (skip IP-hygiene), `--fg` (no-op alias).
**Agents (8):**
- `architect-orchestrator` (opus) — inline reference for the architect workflow
- `feature-matcher` (sonnet) — match brief+research to CC features with brief-anchored rationale
- `gap-identifier` (sonnet) — surface catalog/pattern/decision/outside-CC-scope gaps
- `architecture-critic` (sonnet) — adversarial review with hallucination gate (BLOCKER)
- `skill-author-orchestrator` (opus) — inline reference for the 3-stage authoring pipeline
- `concept-extractor` (sonnet) — read source, output concept JSON with cc_feature/layer/slug
- `skill-drafter` (sonnet) — write `.drafts/<slug>.md` with 9-field frontmatter
- `ip-hygiene-checker` (sonnet) — run `ngram-overlap.mjs`, stamp verdict or delete
**Skill catalog:** `skills/cc-architect-catalog/` (13 files: SKILL.md manifest + 11 seeds + `.drafts/.gitkeep`)
**Scripts:** `scripts/ngram-overlap.mjs` + `scripts/ngram-overlap.test.mjs` (zero-dependency Node)
**Test fixtures:** `tests/fixtures/skill-factory/` (calibration prose for verdict bands) + `tests/fixtures/skill-drafter/slug-collision-expected.md`
### Slug-convention version
Inherits the v2.3.1 slug convention from ultraplan-local: `<cc_feature>[-<qualifier>]-<layer>.md`. Unqualified slug = canonical baseline per (feature, layer); qualified slugs cover specific sub-patterns. Slug-collision hint in `skill-drafter` (v2.3.2) preserved.
### Breaking changes
None at the command level — `/ultra-cc-architect-local` and `/ultra-skill-author-local` keep their names and flag surfaces. Users who installed `ultraplan-local` v2.4.0 must additionally install `ultra-cc-architect` v0.1.0+ to keep using these commands. See `ultraplan-local` v3.0.0 CHANGELOG for migration steps.
### Filesystem contract
Both plugins write into `.claude/projects/{YYYY-MM-DD}-{slug}/`. The directory contract is owned by `ultraplan-local`; this plugin opt-in writes to the `architecture/` subdirectory. No code-level dependency between plugins — the contract is filesystem-level documentation only.
