# LinkedIn Studio Plugin (v0.4.0)

> **Version re-baseline (2026-05-31).** Previously numbered 1.0.0–4.1.0; those were pre-release iterations. The honest maturity is **v0.4.0** — user data still lives inside the plugin tree (`.gitignore`-defended), no command has yet passed the hardening quality-gate, command testing is incomplete, and there is no GUI. The path to **v1.0.0** is four workstreams: **architecture** (move user data out of the plugin into a per-user data dir — the M0 migration), **hardening** (every command through the quality-gate), **command testing**, and a **GUI**. The development narrative below is preserved as history.

Full-spectrum LinkedIn content engine — short-form 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)**: a critical self-review found overclaiming (tracking/analytics/review-independence the plugin couldn't deliver), dormant capability (11 agents never invoked by any command), and structural rot (a dead lint, a self-contradicting algorithm claim, an unpublishable model brand/date in user copy). The fix wires **all 11 orphaned agents** (no deletions → 19 agents), adds **`/linkedin:firsthour`** (→ 27 commands) + a short-form de-AI gate + a video quality gate, promotes `post-feedback-monitor` to Opus, makes the newsletter-distribution / profile-SEO / outreach surfaces honest, **reconciles the algorithm signals to one sourced statement** (no model name or date; `references/algorithm-signals-reference.md` is the single source of truth), fixes the analytics fresh-clone crash, closes the voice-profile leak (placeholder + sentinel + gitignore), and rebuilds the structure lint with version/count/stat/model-consistency + render-chain-propagation + `$`-safety guards (each agent's frontmatter model must match every surface declaration; no honesty pattern a command was cleaned of survives in the reference it renders from — S12; no untrusted value reaches a `String.replace` replacement string in `state-updater.mjs`, proven behaviorally + coverage-complete + self-testing — S13). Breaking — reinstall/reload required for the newly-wired agents; consolidates the v3.0.0 identity break (slug, agent namespace, state-file path). 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). **v3.1.0 (Endring 9)** adds an **adversarial review package** run COLD on a frozen draft — new **Step 6.5 (headless-review)** between the persona sweep (Step 6) and lock, plus a standalone **`/linkedin:headless-review`** command (run in a fresh session for maximum isolation): three new headless archetypes — **`content-reviewer`** (argument integrity), **`language-reviewer`** (Norwegian language), **`fact-reviewer`** (cold re-verification incl. claims a late pivot bolted on) — plus `persona-reviewer` in resonance + conversion modes, all with NO drafting-session context (the independence layer the in-session gates structurally cannot be). v3.1.0 also adds **`/linkedin:pivot`** (re-opens cleared gates after a late change + a >20 %/>2-section pivot-detection gate at lock) and **per-artifact personas** (`articles.NN.personas` — one or more readers configurable per edition, resolved edition-state → series file → plugin library → interactive). Pipeline 15 → 16 phases; agents 16 → 19; commands 24 → 26; additive `personas` / `pivots` / `headlessReview` state. Motivated by Del 4: the in-session editor + persona sweep shared the drafting session's framing-bias, so the version that shipped was never independently re-reviewed. **v4.1.0** adds a **journey layer** over the (unchanged) command surface: two guided front-doors — **`/linkedin:create`** (routes to the right creation command) and **`/linkedin:measure`** (routes to the right analytics command) — plus a router re-tiered into five journeys (Start · Create · Engage · Measure · Grow), with `onboarding`/`strategy` elevated as the Start/Grow front-doors and the 27 atomic commands kept as the execution tier (→ 29 commands). Additive: 14a's cold command-rationalization found **zero redundancy** (no merges/cuts; `docs/remediation/command-rationalization.md` + `journey-layer-design.md`), so the journey layer organizes rather than removes; reload registers the two new commands.

## 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)
- **Analytics metrics (S16):** the parsed CSV columns plus an **optional, manually-entered** `saves` count.
  Saves are count-only in native LinkedIn post analytics (~Sept 2025), absent from the CSV export, and
  have no self-serve API — so the ingest path is the user adding a `Saves` column with the number they
  read off LinkedIn. `parseOptionalCount()` parses it when present: blank / non-numeric / negative →
  `undefined` (`unknown`, never 0), a genuine `0` is kept, and saves is **not** folded into
  `engagementRate` (kept comparable to older imports). Surfaced per-post + as `totalSaves` in the
  weekly/monthly reports; **never auto-tracked**.
- **Unmeasured by design:** `dwell` time stays **explicitly unmeasurable** — internal to LinkedIn for
  organic posts, no exportable count, no API; no dwell field or surface exists. The S16 analytics
  extension routes all I/O through the existing `getAnalyticsRoot()` seam, so the planned per-user
  data-dir migration (UI-brief §9b/M0) relocates the root in one place without reworking the schema.

## 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 (29)

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. **v3.1.0** adds 2 longform companions (`headless-review`, `pivot`) = 24 → 26. **Remediation Step 16** adds `firsthour` (wiring orphan agent #11 `engagement-coach`) = 26 → 27. **v4.1.0 (S14)** adds the two journey front-doors (`create`, `measure`) = 27 → 29. The surface is organized into **five journeys** (Start · Create · Engage · Measure · Grow); `create`/`measure` are new guided front-doors, `onboarding`/`strategy` are elevated as the Start/Grow front-doors, and the 27 atomic commands remain the execution tier (14a found zero redundancy → no merges/cuts).

| Command | Purpose |
|---------|---------|
| `/linkedin` | Router — status line + five-journey command menu |
| `/linkedin:create` | **(v4.1) Create front-door** — guided "what to make?" → routes to the creation command that owns the format (post/quick/react/carousel/video/multiplatform/batch/newsletter); delegates only |
| `/linkedin:measure` | **(v4.1) Measure front-door** — guided "how am I doing?" → routes to the analytics command (import/report/analyze/audit/ab-test); delegates only |
| `/linkedin:onboarding` | Multi-step onboarding wizard (profile → setup → first-post); **Start-journey front-door (v4.1)** |
| `/linkedin:first-post` | First-post accelerator (10 min) |
| `/linkedin:setup` | Guided personalization setup |
| `/linkedin:react` | URL-to-post pipeline |
| `/linkedin:post` | Full post creation (10-15 min) |
| `/linkedin:quick` | 5-minute quick post (3-line formula) + 8 post-type templates |
| `/linkedin:pipeline` | Full end-to-end content pipeline |
| `/linkedin:newsletter` | Long-form orchestrator: newsletter edition / essay / series article — multi-session 16-phase pipeline with **skeleton + spine-prose gates BEFORE prose (v2.1)**, **editorial-review craft gate BEFORE the persona sweep (Step 5.5, v2.4)**, fact-check + persona-sweep BEFORE lock, **headless adversarial review BEFORE lock (Step 6.5, v3.1)**, and **visual-assets gate BEFORE lock (Step 7.5, v2.3)** |
| `/linkedin:headless-review` | **(v3.1)** Cold adversarial review package — run the 3 headless archetypes (`content-reviewer`, `language-reviewer`, `fact-reviewer`) + `persona-reviewer` (resonance/conversion) on a FROZEN draft with no drafting-session context; consolidated, operator-gated report. Step 6.5's standalone surface (run in a fresh session for maximum isolation) |
| `/linkedin:pivot` | **(v3.1)** Re-open a long-form edition after a late substantive change so cleared gates (fact-check → editorial → persona → headless) re-run before lock; logs `pivots[]`, resets `currentPhase`, un-locks if needed (pivot heuristic: >20 % word-count change or >2 new sections) |
| `/linkedin:batch` | Create a full week of content |
| `/linkedin:calendar` | View/manage post scheduling queue + publish action (mark scheduled posts as published) |
| `/linkedin:firsthour` | Post-publish first-hour / reply-loop sprint — delegates to `engagement-coach` for a timestamped target list + draft comments + timeline, persists the plan to state (`recordFirstHourPlan`), hands off to `post-feedback-monitor` |
| `/linkedin:carousel` | Structured multi-slide carousel generator |
| `/linkedin:video` | Video script generator (30s-2min) |
| `/linkedin:multiplatform` | Adapt content for other platforms (short-form/cross-format; long-form → `/linkedin:newsletter`) |
| `/linkedin:analyze` | Content/performance analysis |
| `/linkedin:audit` | Periodic content strategy audit |
| `/linkedin:import` | Import CSV export → structured JSON (delegates analysis to `/linkedin:report`) |
| `/linkedin:report` | Generate weekly performance report |
| `/linkedin:ab-test` | Design and manage A/B content tests |
| `/linkedin:strategy` | Growth strategy + authority building (phase guidance, trajectory, signature content compounding) |
| `/linkedin:competitive` | Competitive analysis of niche |
| `/linkedin:monetize` | Monetization strategy and funnels (unlocks at ~1K followers) |
| `/linkedin:outreach` | Outreach orchestrator — collaborations + speaking opportunities (unlocks at ~1K followers) |
| `/linkedin:profile` | profile/topic-relevance optimization |

**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 (correlate with lower reach; see `references/algorithm-signals-reference.md`)
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 (topic-relevance 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
