# LinkedIn Studio Plugin (v0.7.0)

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. Maturity v0.7.0: M0 (per-user data dir `${LINKEDIN_STUDIO_DATA:-$HOME/.claude/linkedin-studio}/`, idempotent session-start migration — see `references/data-path-convention.md`) complete; the 29 pre-0.7.0 command surfaces all through the interactive quality-gate (`docs/hardening/log.md`) AND through independent cold-review (29/29, R2a–R5 — `docs/hardening/review*.md`); `/linkedin:trends` (shipped in 0.7.0) is not yet through the hardening gate. Remaining for v1.0.0: a GUI. Version history → `CHANGELOG.md`.

## 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 (macOS `pbcopy`, Linux `xclip`/`xsel`, WSL `clip.exe`). All content commands auto-copy
- **iCal generator:** `hooks/scripts/ical-generator.mjs` — RFC 5545 calendar files for batch scheduling. Standalone CLI + importable module
- **Figure renderer:** `render/build-figur.mjs` — coded data figures (SVG/HTML → PNG via headless Chrome); three targets (article/carousel/single); brand tokens from the user data dir's `profile/brand-tokens.json`, neutral defaults otherwise (see `references/figure-design-guidelines.md`). Standalone CLI + importable module
- **Post queue:** `assets/drafts/queue.json` (managed by `hooks/scripts/queue-manager.mjs`)
- **Analytics:** CLI `scripts/analytics/` (TypeScript, needs `tsx` + `npm install`); data `assets/analytics/` (gitignored)
- **Specifics-bank:** `scripts/specifics-bank/` (TypeScript, needs `tsx` + `npm install`) — deterministic, topic-tagged store of the operator's lived specifics (real numbers, named cases, held opinions) in the per-user data dir; elicited/bound by `/linkedin:newsletter` Step 1.5 so drafts draw from real inventory, never invented filler. Consumption is logged back at Step 8 lock (`record-usage` → `usedIn`), so cross-edition re-use of the same material is visible rather than silently encouraged by the dedupe
- **Series distillate:** `scripts/editions/` (TypeScript, needs `tsx` + `npm install`) — series-level memory: each locked edition's spent narrative units (anecdotes/arguments/hooks) in `<serie>/linkedin/series-distillate.json`; written at `/linkedin:newsletter` Step 8 (`distil-append`), checked against the next skeleton at Step 2.5 (`distil-check`, advisory). Deterministic character-trigram similarity — AI extracts, code compares
- **Editions register:** `scripts/editions/` (same package) — one row per edition in production in the per-user data dir (`editions/register.json`): series, edition, path, current phase, next action, slot, `startedAt`/`completedAt`. Each of the 17 canonical `/linkedin:newsletter` phase transitions runs `register-upsert --edition-state <path>`, which appends `articles.NN.phaseLog` (lead-time telemetry, additive — schemaVersion stays 1) **and** mirrors the row in one call; Step 10 runs `register-complete`. `register-list` is the work-in-progress view. The register is a **mirror** — deterministic resumption reads `edition-state.json` only, and a lost register is rebuilt by the next transition
- **Publishing slots:** `hooks/scripts/slots.mjs` — the weekly production grid. Slots are **operator config** in the per-user data dir (`profile/publishing-slots.json`, schema + opt-in template in `config/publishing-slots.template.json`); absent config ⇒ every slot surface stays silent, and the plugin hardcodes no publishing times. Coverage of a slot counts the short-form queue (`scheduled`/`published`) **and** editions-register rows claiming that date, so long-form and short-form cannot be double-booked. Zero-dep (SessionStart may not spawn tsx) and imported identically by the hook and by the commands (`queue-manager.mjs` pattern), so session-start's vacancy warning and `/linkedin:newsletter` Step 10's slot default are the same computation
- **Contract-gate:** `scripts/contract-gate/` (TypeScript, needs `tsx` + `npm install`) — deterministic §B/§C1 rule-gate on the full draft (`/linkedin:newsletter` Step 4.5, before the AI sweeps); ratifies `rules.ts` against the edition's §E-manifest, then gates with BLOCK/WARN
- **Fold-in loop:** capture → classify → promote → enforce, documented domain-generally in `references/fold-in-loop.md`. The four `/linkedin:newsletter` steps where operator judgment enters the text (2.5, 3a, 5.5, 6.5) append corrections to `articles.NN.foldIns[]` (`decision: "pending"`); **Step 11 (retro)** empties the queue with an explicit operator JA/NEI — mechanical → an atomic contract-gate promotion (only counts when `--ratify` is green), judgment → the operator's opt-in language-rules file (`${DATA}/language-rules/<lang>.md`, template `config/language-rules.template.md`), which Step 4 reads while drafting (prevent) and `language-reviewer` reads at Step 6.5 (catch). Rejected rows are kept, never deleted. Step 11 also reports effort from the **measured** `phaseLog` and asks one friction question whose answer goes back to the operator — the plugin never writes their register
- **Analytics metrics (S16):** parsed CSV columns + an optional, manually-entered `saves` count (count-only in native LinkedIn analytics since ~Sept 2025, no CSV export; the Marketing API exposes `POST_SAVE` on `/memberCreatorPostAnalytics` from v202604, but access is partner-gated — so manual entry remains the right UX). `parseOptionalCount()`: blank / non-numeric / negative → `undefined` (`unknown`, never 0), a genuine `0` is kept; saves surfaced per-post + as `totalSaves`, but **not** folded into `engagementRate`. `dwell` stays **explicitly unmeasurable** (internal to LinkedIn, no export/API). All analytics I/O routes through the `getAnalyticsRoot()` seam (M0 per-user data-dir).

## 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, editions in flight + publishing-slot vacancy |
| `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`, `slots.mjs`.

**State updates:** post tracking, streak, and content history are handled deterministically by `state-updater.mjs` (Stop hook + commands); 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 load at runtime via gatekeeper scripts; the compile step is only needed when adding `type: prompt` hooks.

## Commands (30)

All content commands auto-copy output to clipboard via `clipboard-helper.mjs`; interactive steps are minimized (angle/format/post-type inferred from context, max 2 questions per post). Organized into five journeys (Start · Create · Engage · Measure · Grow): `create`/`measure` are guided creation/analytics front-doors, `onboarding`/`strategy` the Start/Grow front-doors, and the 28 atomic commands are the execution tier.

| Command | Purpose |
|---------|---------|
| `/linkedin` | Router — status line + five-journey command menu |
| `/linkedin:create` | Create front-door — routes to the command owning the format (post/quick/react/carousel/video/multiplatform/batch/newsletter); delegates only |
| `/linkedin:measure` | Measure front-door — 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 |
| `/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:trends` | Trend discovery pass — delegates to `trend-spotter` (default long-form mode), persists to trend store + dated morning brief, triage per id (act/skip) |
| `/linkedin:newsletter` | Long-form orchestrator (newsletter / essay / series article) — multi-session 19-phase pipeline with gates before prose (skeleton + spine), fact-check, editorial-review (Step 5.5), persona sweep, headless adversarial review (Step 6.5), and visual-assets — all before lock; closes with the Step 11 retro that promotes this edition's corrections so the next one starts with them enforced |
| `/linkedin:headless-review` | Cold adversarial review package — 3 headless archetypes (`content-reviewer`, `language-reviewer`, `fact-reviewer`) + `persona-reviewer` on a FROZEN draft, no drafting-session context; operator-gated report (Step 6.5 standalone surface). `--background` runs the package in a background agent that writes the report to disk — fresh-session isolation without the paste-back seam |
| `/linkedin:pivot` | Re-open a long-form edition after a late substantive change so cleared gates re-run before lock (pivot heuristic: >20% word-count or >2 new sections) |
| `/linkedin:batch` | Create a full week of content |
| `/linkedin:calendar` | View/manage post scheduling queue + publish action |
| `/linkedin:firsthour` | Post-publish first-hour / reply-loop sprint — delegates to `engagement-coach`, persists the plan (`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 (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; Grow-journey front-door |
| `/linkedin:competitive` | Competitive analysis of niche |
| `/linkedin:monetize` | Monetization strategy and funnels (unlocks at ~1K followers) |
| `/linkedin:outreach` | Outreach orchestrator — collaborations + speaking (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:** a NEW agent file under `agents/` registers only after a Claude Code **session reload** (the plugin agent set is built at session start). Reload before invoking a freshly-added agent.

## 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
