# LinkedIn Studio Plugin (v2.4.0)

Full-spectrum LinkedIn content engine — short-form feed posts, carousels, video scripts, and long-form newsletter editions — with the January 2026 360Brew algorithm baked in. v2.0.0 consolidated the surface (27 commands → 24, 16 agents → 14) while adding the long-form `/linkedin:newsletter` orchestrator + two longform-quality gate agents (`fact-checker`, `persona-reviewer`). v2.1.0 added two gates BEFORE prose (Step 2.5 skeleton + Step 3a spine prose) + a third `persona-reviewer` mode (`skjelett`). v2.2.0 hardened the longform gates with the lessons from the second production run (Seres-serien): blocking persona hard-fails, a post-cutoff fact-check mandate, a `voice-scrubber` agent, render+annotate operator gates, and STATE.md-reconciled edition state. v2.3.0 made **visual assets an explicit pipeline phase** — Step 7.5 (visual-assets) between annotation (Step 7) and lock (Step 8): cover (+ optional inline figures) or a carousel deck, generated (default `mcp-image`, external `cover-raw.png` accepted) and operator-gated BEFORE lock so `render/build-linkedin.mjs` picks up `cover.png` at lock without a post-lock re-render. **v2.4.0** makes an **editor's craft gate an explicit pipeline phase** — new **Step 5.5 (editorial-review)** between fact-check (Step 5) and the persona sweep (Step 6): a new **`editorial-reviewer` agent** (Opus) judges **craft** (prosa-håndverk + narrativ-arkitektur), not reader-response, returning ≤10 flags (BLOCK/REWORK/NICE) as direction, **operator-gated via `SendUserFile` BEFORE the persona sweep** so the personas measure resonance instead of stumbling on craft noise. Motivated by Del 4: every persona reported PASS, yet the editor found 8 fresh points on first reading, ~6/8 of them craft/architecture blind spots no agent measured. Mirrors the Maskinrommet writing-contract §C2. Pipeline 14 → 15 phases; agents 15 → 16; additive `editorialReview` state. Doc/orchestration-only for the wiring (the new agent + its fasit fixture + lint test are the only new files); commands unchanged (24).

## Architecture

- **State file:** `~/.claude/linkedin-studio.local.md` (YAML frontmatter, auto-initialized from `config/state-file.template.md`)
- **State updater:** `hooks/scripts/state-updater.mjs` — deterministic state mutations (post tracking, streak, content history pruning). Pure functions, tested, no AI involvement
- **Clipboard helper:** `hooks/scripts/clipboard-helper.mjs` — cross-platform clipboard integration (macOS `pbcopy`, Linux `xclip`/`xsel`, WSL `clip.exe`). All content commands auto-copy to clipboard
- **iCal generator:** `hooks/scripts/ical-generator.mjs` — RFC 5545 calendar file generation for batch scheduling. Standalone CLI + importable module
- **Post queue:** `assets/drafts/queue.json` (managed by `hooks/scripts/queue-manager.mjs`)
- **Analytics CLI:** `scripts/analytics/` (TypeScript, requires `tsx` and `npm install`)
- **Analytics data:** `assets/analytics/` (gitignored)

## Hooks

9 hooks across 7 events. All Node.js (.mjs). PreToolUse/PostToolUse hooks use parameterized `content-gatekeeper.mjs` with `isLinkedInContent()` check.

| Event | Purpose |
|-------|---------|
| `SessionStart` | Load state, REMEMBER.md, milestone tracker |
| `PreToolUse` (Write\|Edit) | Content quality gate, voice guardian, topic rotation gate |
| `Stop` | State update, pre-publish reminders, content history |
| `UserPromptSubmit` | LinkedIn context enrichment (three-tier matching) |
| `PostToolUse` (Write) | Post-creation automation (5x5x5, posting time) |
| `PreCompact` | Preserve LinkedIn context during compaction |
| `Notification` | Posting reminders (rate-limited 30min) |

**Session markers:** `/tmp/linkedin-hooks/session-active` (Stop hook gating, 12h staleness). **Shared modules:** `linkedin-content-filter.mjs`, `queue-manager.mjs`, `personalization-score.mjs`, `state-updater.mjs`, `clipboard-helper.mjs`.

**State updates:** Post tracking, streak management, and content history are handled deterministically by `state-updater.mjs` (called from Stop hook and commands). Content history entries older than 90 days are auto-pruned at session start.

**Hook editing:** Edit `hooks/hooks.template.json` + `hooks/prompts/*.md`, then run `python3 hooks/scripts/compile-hooks.py`. Do not edit `hooks.json` directly. Prompts are loaded at runtime by gatekeeper scripts; the compile step is only needed when adding `type: prompt` hooks.

## Commands (24)

All content commands (post, quick, react, pipeline, first-post, video, multiplatform, carousel, newsletter) auto-copy output to clipboard via `clipboard-helper.mjs`. Interactive steps are minimized — angle, format, and post type are inferred from context, with max 2 questions per post. **v2.0.0 net change:** 5 commands removed (`templates`, `publish`, `authority`, `collab`, `speaking` — absorbed into `quick`, `calendar`, `strategy`, `outreach` respectively) + 2 commands added (`newsletter`, `outreach`) = 27 → 24.

**Rule:** Always read `assets/voice-samples/` before generating content.

**Invocation form:** Commands invoke plugin agents by their **namespaced** type —
`subagent_type: linkedin-studio:<name>` — never the bare `<name>` (a bare
type does not resolve and the `Task` call fails).

**Reload requirement:** Adding a NEW agent file under `agents/` registers it only after
a Claude Code **session reload** — the plugin agent set is built at session start, so a
freshly-added agent (e.g. `fact-checker`, `persona-reviewer` when first added) is not
invokable until the session reloads. After adding an agent, reload before invoking it.

## Content Quality Rules

1. Hook: 110-140 characters (mobile cutoff)
2. Post length: 1,200-1,800 chars (standard), 150-500 chars (quick)
3. No external links in post body (40-50% reach suppression)
4. No corporate buzzwords: leverage, synergy, paradigm shift, thought leader, disruptive, value proposition, ecosystem, holistic approach
5. Topic must align with user's 5 core expertise areas (360Brew signal)
6. Topic rotation: no back-to-back same pillar, no pillar >50% in 14 days (warn-only)
7. Progressive onboarding: personalization score hidden until 3+ posts; voice guardian suppressed until 5+ voice samples
