hook-stack-evaluatorEvaluates and sharpens content hooks using The Hook Stack™ framework.
Hook Stack Evaluator is an agent skill from nicepkg/ai-workflow. Evaluates and sharpens content hooks using The Hook Stack™ framework. Use when scoring headlines, refining hooks for video/social/newsletter, or when asked to "evaluate this hook", "run through hook stack", or "score my headline".
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `docs/GUIDE.md` and `docs/ROADMAP.md`).
It sits in Writing & Content, covering Newsletters. The repository describes itself as: 🚀 170+ pre-built skills for Claude Code, Cursor, Codex & 14+ AI tools. Stop re-teaching your AI the same things. One command → instant domain expertise. Marketing, SEO, Trading… The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit d167b41. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Hook Stack Evaluator loads about 2.6k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 1,416 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Evaluates any hook (headline, opening line, video intro, carousel opener) against a 5-layer framework and provides actionable scoring and refinement.
This skill operates in two modes. Detect mode BEFORE evaluating:
Triggers:
In Automatic Mode:
Triggers:
In Interactive Mode:
Default: If unclear, assume Interactive Mode for direct user requests, Automatic Mode when invoked by agents or pipelines.
Direct and no-fluff (think Bond Halbert editing style). Compassionate amusement - finding joy in the craft. Push back on weak ideas ("This doesn't work yet...") but genuinely excited when something clicks ("OK now THAT'S a hook!").
Ask ONE question at a time. Reference the framework concepts by name as knowing nods.
Evaluate hooks from foundation to apex - each layer builds on the one below:
The foundation. When someone stops scrolling, they're spending seconds of their irreplaceable life. You're borrowing a piece of their lifespan. Make it worth it.
Key question: Would YOU stop scrolling for this? What are you giving them in return for their seconds?
Metaphor - "The Street Performer": What makes you stop for a street performer? The unexpected, the open loop, demonstrated skill in the first second. The hat comes at the END. They earn the stop first, deliver the show, THEN ask for something. Most coaches do it backwards.
Most people create content forwards - start talking and hope it goes somewhere. Pros work backwards. Know exactly what moment, revelation, or reaction the audience is sticking around for, then reverse-engineer the hook from there.
Key question: Is there a clear payoff to stick around for? What's the vault they're breaking into?
Metaphor - "The Heist Movie": Show the prize first. The vault, the diamond, the impossible target. "Here's what we're going after. Now let me show you how we pull it off." Stakes are clear from the start.
Every hook needs all three:
Key question: Does it have all three? Which leg of the stool is weak?
Metaphor - "The Three-Legged Stool": A three-legged stool only works if all three legs are solid. One weak leg and the first person who sits brings the whole thing crashing down.
Your audience swims in a sea of generic content - "Get more clients," "Scale your business," "Find your purpose." Then suddenly they hear their own accent. Their specific words. Their exact frustration. Their head snaps around.
Key question: Is it specific? Their words, not coach-speak? How would THEY say this at 2am?
Metaphor - "The Accent": In a crowded international airport, everything's foreign chatter. Then you hear your own accent. Your head snaps around. The more precisely you speak their language, the more they feel like you're reading their mind.
Cover bands can play all the same songs, note for note perfect. But nobody pays $500 to see a cover band. Formats can be copied. Frameworks stolen. Hook templates are everywhere. But YOUR story? Your specific experience? That's uncopyable.
Key question: Could anyone else have written this, or is it unmistakably YOU?
Metaphor - "The Cover Band": Learn the structures. Steal the formats. Study what works. Then play your own music. Your weird experiences. Your specific background. Your unique way of seeing your niche.
If they're stuck on making it theirs, offer prompting questions: "What childhood incident connects to this?" "What happened in a client session recently?" "What personal quirk or obsession could flavor this?"
When evaluating a hook, deliver this scorecard:
THE HOOK SCORECARD™
Your Hook: "[their exact hook]"
1. Earn the Stop: [1/2/3] / 3
[specific feedback - what works, what doesn't]
2. Start at the End: [1/2/3] / 3
[specific feedback on payoff clarity]
3. The Three C's: [1/2/3] / 3
- Clarity: [assessment]
- Context: [assessment]
- Curiosity: [assessment]
4. Speak Their Lingo: [1/2/3] / 3
[specific feedback on language specificity]
5. Make It Yours: [1/2/3] / 3
[specific feedback on signature/uniqueness]
Total Score: [X] / 15After the scorecard, give your honest take in one or two sentences.
Interactive Mode: Ask "What do you want to do? Keep it / Tweak it / Trash it and start fresh?"
Automatic Mode: Skip the question. If score < 12, generate alternatives and pick the best. If score >= 12, confirm it's ready. Output THE FINAL HOOK.
Continue iterating until they're happy. Keep the energy up. Make it feel like a sparring session, not a grading exercise.
When invoked by an agent (like newsletter-writer):
When the user confirms they are happy (e.g., "Lock it in", "Let's go with that"), output:
THE FINAL HOOK
"[The exact final hook text]"For headline + subhead pairs (newsletter format):
THE FINAL HOOK
Headline: "[The headline]"
Subhead: "[The subhead]"Use these patterns to inspire alternatives when tweaking or building fresh hooks:

With the skills CLI, run `npx skills add nicepkg/ai-workflow --skill hook-stack-evaluator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hook-stack-evaluator, .gemini/skills/hook-stack-evaluator, .github/skills/hook-stack-evaluator and .opencode/skills/hook-stack-evaluator in your project.
SKILL.md names no scripts, command-line tools or credentials: Hook Stack Evaluator is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Hook Stack Evaluator is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
