   "description": "LinkedIn Studio — full-spectrum LinkedIn content engine: feed posts, carousels, video scripts, and long-form newsletter editions, with the 2026 relevance-ranking model baked in. v4.0.0 is an audit-remediation release (Voyage Phase 0–3): every user-facing claim is made honest or removed, all 11 previously-orphaned agents are wired (→ 19 agents), a `/linkedin:firsthour` post-publish command is added (→ 27 commands), the algorithm-signal claims are reconciled to one sourced statement (no unpublishable model name or date), short-form de-AI and video quality gates are added, and the structure lint is rebuilt to guard the real layout plus version/count/stat consistency. Breaking: the newly-wired agents register only on reinstall/reload, and this consolidates the v3.0.0 identity break (slug, agent namespace `linkedin-studio:<agent>`, state-file path `~/.claude/linkedin-studio.local.md`). v3.1.0 added the cold adversarial review package (`/linkedin:headless-review` + Step 6.5 + `/linkedin:pivot` + per-artifact personas); the `/linkedin:*` commands are unchanged. v4.1.0 adds a journey layer: two guided front-doors (`/linkedin:create`, `/linkedin:measure`) plus a router re-tiered into five journeys (Start · Create · Engage · Measure · Grow), with the 27 existing commands kept as the execution tier (→ 29 commands; additive, reload registers the two new commands).",

+
+### Changed — registration hygiene: agent fasit fixtures moved out of `agents/`
+
+**Stops Claude Code from registering 6 spurious agents.** The six long-form-review fasit fixtures lived in `agents/fixtures/*-cases.md`; because Claude Code scans `agents/` recursively, each was registered as a junk `fixtures:*` agent (`fixtures:content-reviewer-cases`, …). They are test fixtures, not capabilities. **Count-neutral** (no real agent/command/reference/skill change; `ls agents/*.md` still 19) — pure namespace hygiene.
+
+- **Moved** the 6 fasit fixtures `agents/fixtures/*-cases.md` → `tests/fixtures/*-cases.md`, and their 6 lint tests `agents/__tests__/*-fixture.test.mjs` → `tests/*-fixture.test.mjs` (co-located; each test's relative fixture path retargeted `../fixtures/` → `./fixtures/`). `agents/fixtures/` and `agents/__tests__/` are now removed.
+- **Retargeted** the 5 agent fasit-refs (`content`/`language`/`persona`/`editorial`/`fact-reviewer`) from `${CLAUDE_PLUGIN_ROOT}/agents/fixtures/…` to `${CLAUDE_PLUGIN_ROOT}/tests/fixtures/…`.
+- **Tests.** Fixture-lint 35/35 at the new path (`node --test 'tests/*.test.mjs'`); render 20/20, hooks 139/139 unaffected; gate `scripts/test-runner.sh` green (counts + version-consistency). Reinstall/reload required for the 6 spurious agents to disappear from the registry.

 > **Version re-baseline (2026-05-31) · M0 landed (2026-06-18, v0.5.0).** Previously numbered 1.0.0–4.1.0; those were pre-release iterations. The honest maturity is **v0.5.0** — **the architecture workstream (M0) is complete: user data now lives in a per-user data dir (`${LINKEDIN_STUDIO_DATA:-$HOME/.claude/linkedin-studio}/`) resolved through one seam per runtime, with automatic idempotent migration on session-start** (see `references/data-path-convention.md`). No command has yet passed the hardening quality-gate, command testing is incomplete, and there is no GUI. The remaining path to **v1.0.0** is three workstreams: **hardening** (every command through the quality-gate), **command testing**, and a **GUI**. The development narrative below is preserved as history.
