Signal — LinkedIn Authority Engine
The productized LinkedIn layer of ACOS, and the flagship vertical of The Studio. Signal is a thin, sellable configuration of the general Excellence Loop — the same eight steps, wearing a LinkedIn skin.
Two things make Signal different from "an AI that writes LinkedIn posts":
- It runs a critique + learning loop. Every draft passes an independent voice/claim/hook check before it's shippable, and every shipped post's performance is written back so next week's drafts are grounded in what actually worked — not a blank prompt.
- It never posts for you. LinkedIn's terms forbid automated posting through unofficial means. Signal drafts, critiques, and stages; a human clicks post. This is the compliant design and the simpler one.
The two-brand model
Signal always operates under one of two voices, loaded from personas.md:
- Personal — the individual's authority voice (first-person, opinionated, career/insight-led).
- Company — the brand's voice (we/product-led, proof and customer-outcome-led).
Same engine, two lenses. Pass brand: personal or brand: company; default is personal. Never blend the two in one draft — pick the lens first.
Modes (the command surface)
Invoke via /signal <mode>. Each mode is a segment of the Excellence Loop.
| Mode |
Loop step |
What it does |
plan |
Ideate |
Reads the voice corpus + recent winners → a week of ranked angles mapped to pillars. |
draft |
Craft → Execute |
One idea/source → a LinkedIn draft in the chosen brand voice, staged as a draft. |
repurpose |
Execute |
Fetch a great external clip/post (Firecrawl) → a credited reframe. Highest-ROI motion. |
critique |
Critique + Verify |
Runs integrity-guard (brand/claim/schema) + a hook/format check. Returns PASS / warn / FAIL. |
ship |
Interconnect |
Exports the passed draft to a Typefully/LinkedIn draft via official API. A human posts. |
learn |
Learn |
Takes supplied post analytics → writes the graded outcome to the store → tunes next week. |
research |
Ideate |
Sweeps the source lanes (papers / videos / pdfs / posts) and vets them. See research-sources.md. |
carousel |
Execute |
A post → brand-locked carousel slides via multimodal + canvas-design. |
infographic |
Execute |
A post / data → a brand-locked infographic. |
engage |
Distribute |
Dream100 newest posts → substantive comment drafts. A human posts each. |
index |
— |
Index your existing content (posts / talks / repos) into the searchable library. |
If no mode is given, route by intent: a pasted URL → repurpose; "plan my week" → plan; a raw idea → draft; "who should I engage" → engage.
Command surface: /linkedin <mode> (memorable front door) and /signal <mode> are the same engine.
The non-negotiables
- Never auto-post. No mode calls a posting endpoint.
ship produces a draft a human confirms. This is a hard stop inherited from the root CLAUDE.md (posting to LinkedIn is human-gated) and from LinkedIn ToS.
- Critique gates ship.
ship refuses a draft that hasn't passed critique. Fail-closed.
- Credit is mandatory on
repurpose. A reframe of someone else's clip names the source, on its own line, every time.
- No fabricated metrics. Follower counts, view counts, "top voice" claims obey the Metrics-Truth rule — verify or omit.
learn only writes numbers a human supplied from real analytics.
LinkedIn format discipline (the format pass)
Applied to every draft, from knowledge.md:
- Plain text — LinkedIn renders no markdown. No
#, *, or - bullets that won't render; use line breaks and unicode where needed.
- Hook in the first 1–2 lines (before the "…see more" fold). The scroll stops here or nowhere.
- One idea per 1–2 lines, generous line breaks — LinkedIn is skimmed on mobile.
- ≤ 3 hashtags, at the end. One link, on its own line near the close (links suppress reach — place deliberately).
- Match the persona's emoji/exclamation rules exactly (personal and company differ — see
personas.md).
The operating manual
DAILY_LOOP.md — the daily rhythm (≈45 min of your time: ideate → draft → design → critique → ship → engage → learn) + weekly cadence.research-sources.md — the best-of-best intake lanes (papers / videos / pdfs / posts), the vetting bar, and the signal→post pipeline.agent-team.md — the multi-agent org (lead + researcher / ideator / drafter / designer / engagement + independent critic).../../docs/architecture/SIGNAL_ROADMAP.md — the road to Top Voice + the product stages.
The knowledge base (the moat)
knowledge.md holds the reusable intelligence Signal draws on: the hook taxonomy, the format playbooks (text post · document/carousel · article · repurpose), and the Dream100 method. This is the asset that compounds — it grows every time learn records what worked.
What to build next (this pack is a scaffold)
Per L99_BLUEPRINT.md, Signal is only real once the loop closes. The build order:
- A
content table (state spine) so draft/ship persist instead of vanishing.
ship wired to the Typefully/LinkedIn official draft API.learn wired to the Success Oracle store so performance tunes the next plan.
Until then, Signal drafts and critiques honestly — and says so.
