Hook Generator
Workflow
Generate hooks for platform P from spine S:
- [ ] Step 1: Pull best_hook_candidates + thesis + opening claim from spine
- [ ] Step 2: Apply platform hook rules (see below)
- [ ] Step 3: Generate 3-5 candidates
- [ ] Step 4: Score each: attention (1-5), voice-fidelity (1-5), truth-fidelity (1-5)
- [ ] Step 5: Drop any hook scoring <4 on voice-fidelity
- [ ] Step 6: Return sorted list
Platform hook rules
| Platform | Length cap | Pattern | Notes | |---|---|---|---| | Substack Note | 1–2 sentences | confession preferred | Can use em-dash reframe; closest to essay opener | | X (hook tweet) | ≤240 chars | confession or bold claim | No question unless genuine; no "here's what I learned" | | LinkedIn | ≤210 chars total (first 1–2 lines) | practitioner confession | "I spent four months…" > "I had a realization…" | | Cross-post | N/A | third-person positioning | "In this piece, Kushal argues…" |
Worked example
Platform: X. Spine from The Execution Gap.
Candidates:
- Confession (attention 5, voice 5, truth 5): "I have been meaning to open a Kalshi account for months. Not casually — the way you mean to clean the garage."
- Reframe (attention 4, voice 5, truth 5): "This isn't a story about prediction markets. It's a story about the distance between learning about something and actually doing it."
- Bold claim (attention 4, voice 4, truth 5): "Most 'learning' about a domain is substitution for doing the thing."
- Question (attention 3, voice 3, truth 5) — DROPPED: "Why do so many of us substitute learning for doing?" — too generic for the writer's voice.
Return 3 candidates (dropped the one below voice-fidelity 4).
Guardrails
- Never generate a hook that promises something the essay doesn't deliver.
- Never use "AI is transforming…" / "In today's fast-paced…" / "Let's explore…" in any hook.
- Don't start with a stat unless the stat is in the essay.
- Don't propose a hook whose voice-fidelity score is <4 — drop it, don't include.
- Per platform, stay within the length cap — a 300-char X hook that would fit in two tweets is not a hook, it's a thread.
- Cross-post hook uses third person; never "I" in that variant.

lyndonkl/wc-transfer-planner
development
VerifiedTrustedCommunity
Plans between-round FIFA World Cup Fantasy transfers — budgets the round's free transfer(s), forces out players whose nation has been eliminated, chases fixture-swing drops, upgrades on value, and decides when a rebuild is large enough to fire the Wildcard instead of spending free transfers one at a time. Ranks candidate in/out pairs by EV gain over each player's remaining survival horizon (delta xEV weighted by progression_carry) MINUS transfer cost (a free transfer is cheap, a points hit is real, churning the squad for marginal swings is a critic flag), and tags forced/fixture/upgrade priority. Emits a `transfer-plan` signal. Use when called by wc-squad-architect (whose transfer work this skill is the engine for) and by the strategists in the populate stage when their candidate is transfer-adjacent rather than a full rebuild.

lyndonkl/wc-tournament-state
testing
VerifiedTrustedCommunity
Reads and updates the FIFA World Cup Fantasy tournament state machine (footballfantasy/context/tournament-state.md) — the temporal backbone tracking phase (pre-tournament → group MD1-3 → R32 → R16 → QF → SF → final), budget ($100m group / $105m knockouts), nation cap (3 group, loosening in knockouts), chips remaining, surviving nations, each owned player's elimination-risk horizon, and deadlines. Validates state on load (count/feasibility checks), applies phase transitions, and appends to the append-only state log (never silent overwrite). Use to load state at the start of a run and to commit state changes after the manager makes a move.

lyndonkl/wc-signal-emitter
development
VerifiedTrustedCommunity
Validates and persists FIFA World Cup Fantasy signal files to signals/YYYY-MM-DD-<type>.md. Checks the required frontmatter (type, round, date, emitted_by, confidence, source_urls), range-checks declared numeric signals, confirms every factual claim carries a source URL or "manager-provided", rejects unknown signal types, and refuses to persist a signal that fails validation (logging the failure instead). Keeps the inter-agent signal layer auditable so downstream agents can trust what they read and never re-derive it. Use whenever an agent or skill writes a signal.
