hook-gokil

hook-gokil is a skill for Claude Code, Codex from konten-studio/jekardah-writer. It costs 56 tokens per session (1,217 once invoked), scanned A, original, MIT.

A writing aid for creating and reviewing opening lines, also called hooks, for Indonesian, multilingual, and other content. It aims to create curiosity without making claims that the source material cannot support.

In plain words
What is it for?
Use it for drafts, scripts, posts, carousels, threads, headlines, and content ideas. It can suggest hook options, diagnose existing openings, choose candidates, and rewrite them without adding unsupported facts.
Why use it?
Weak openings may fail to hold attention, while exaggerated ones can mislead readers. This helps compare and improve hook ideas while keeping them factually honest.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hook-gokil scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hook Gokil

Create cognitive dissonance without breaking the content's factual contract. A strong hook makes the audience ask "kok bisa?"; the body must answer honestly.

Load only what you need

  • Read references/framework.md for the full analysis, generation, scoring, and rewrite method.
  • Read references/types.md when choosing among the 15 WTF/killer hook types or three emotional pillars.
  • Read references/examples.md for calibrated Indonesian examples, unsafe-to-safe repairs, and output shapes.
  • Read references/provenance.md only when auditing the skill's design influences. Do not load evals/ during normal use; it contains maintainer evaluation artifacts, not operating instructions.
  • Use the distilled files in references/ for the framework, hook types, examples, and provenance. The private source material is intentionally not bundled with this public skill.

Non-negotiable truth contract

Treat the source draft/context as the claim ceiling.

  1. Lock facts before ideation: names, numbers, dates, scope, evidence level, causal direction, quotes, and stated outcomes.
  2. Never invent proof, precision, authority, consensus, urgency, scarcity, or personal experience.
  3. Never upgrade anecdote to science, correlation to causation, possibility to certainty, or one case to a universal rule.
  4. Use only a contradiction the body can resolve. If payoff is missing, weaken the hook or ask for evidence; do not manufacture a payoff.
  5. Preserve the author's factual meaning even when rewriting the whole draft.

If the user requests an unsupported claim, decline that claim briefly and offer the strongest accurate alternative. "Killer" describes attention strength, not permission to deceive.

Core workflow

  1. Parse the request. Identify deliverable, platform if supplied, language/register, audience, topic, desired outcome, and whether the user wants analysis, candidates, selection, a hook rewrite, or a whole-draft rewrite. Ask only when a missing fact would materially change the result.
  2. Build a fact lock. Separate supported facts, opinions/interpretations, unknowns, and forbidden upgrades. Preserve exact numbers unless rounding is explicitly allowed.
  3. Extract depth. Move from feature/topic to benefit or pain, then ask "so what?" until reaching a defensible human meaning. Do not turn a plausible scenario into an asserted event.
  4. Choose angles. Select 3-5 suitable types from references/types.md. Prefer variety over cosmetic paraphrases. Skip any type that requires unavailable proof.
  5. Generate. Unless the user specifies a count, produce 6 candidates across at least 3 types and at least 2 emotional pillars. Put the strongest concrete or disruptive words early. Write natural Indonesian; use English/code-mixing only when it matches the source or requested voice.
  6. Stress-test. Apply the body-payoff, fact-lock, specificity, first-words, clarity, and curiosity checks in references/framework.md. Repair or discard failures.
  7. Select. Score viable candidates, choose one strongest hook, name its type, and explain in 1-3 sentences why it wins and how the body pays it off. Accuracy is a gate, not a weighted tradeoff.
  8. Rewrite only the requested scope. If asked for one hook, do not rewrite the body. If asked for the whole draft, place the selected hook first and reshape the body so it closes the exact curiosity gap without adding claims.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
