What it does
Headline Engineering is an agent skill from assafkip/kipi-system. Platform-optimized headline and hook engineering for X (Twitter), Reddit, LinkedIn, Medium, Substack. Apply when writing or reviewing any title, tweet, thread opener, Reddit post title, or social hook intended for public publication. Triggers on "write a headline", "draft a tweet", "X thread", "Reddit post", "LinkedIn post", "Medium article", "make this hook stronger", "shorter title", "more clickable", "the title is too long", or any time a draft has a title that will be seen by people outside the company.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/headline-templates.md`, `references/platform-hooks.md` and `references/research-receipts.md`).
It sits in Writing & Content, covering Social media posts and Newsletters. It works with LinkedIn, Reddit, Substack and X (Twitter). The repository describes itself as: Your AI brain, externalized. It remembers everything you do, then becomes whatever role you need. Same skeleton can run as your chief of staff, lawyer, PM, or investigator. Plain… The licence is MIT.
When your agent uses it
- Write a headline
- Make this hook stronger
- The title is too long
- Any time a draft has a title that will be seen by people outside the company
Example prompts
- “write a headline”
- “draft a tweet”
- “X thread”
- “/headline-engineering”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Always load references/platform-hooks.md — the 6 viral patterns, char-count sweet spots, first-7-words rule.
- For specific platforms load references/headline-templates.md — proven shapes per platform with char counts.
- For challenges or updates load references/research-receipts.md — the source data behind every claim in this skill.
What it can do on your machine
Read from SKILL.md and the folder at commit 16d4724. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Headline Engineering loads about 1.1k tokens when it runs, and up to ~5.5k if it reads all its reference files. Until then it costs about 133 tokens; SKILL.md has 571 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.
Safety
Auto-check passed
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.

- Platform-optimized headline and hook engineering for X (Twitter), Reddit, LinkedIn, Medium, Substack.

Headline Engineering
This skill fires whenever someone is writing or reviewing copy that has to earn a click.
It does NOT replace [[assaf-voice]] — voice DNA still applies. This skill handles the part voice doesn't: WHERE the copy will live and HOW that platform's audience decides what to click.
Load order
- Always load
references/platform-hooks.md— the 6 viral patterns, char-count sweet spots, first-7-words rule. - For specific platforms load
references/headline-templates.md— proven shapes per platform with char counts. - For challenges or updates load
references/research-receipts.md— the source data behind every claim in this skill.
The decision tree
Apply in order:
Step 1 — Identify the platform. Different platforms have different optimal lengths and reward different shapes. Don't write a "headline" abstractly. Write for X, OR for Reddit, OR for LinkedIn, OR for Medium. The same idea gets phrased four different ways.
Step 2 — Identify the length range.
- X: under 110 chars, sweet spot 71-100
- Reddit text titles: 30-66 chars
- LinkedIn long-form titles: 60-100 chars
- Medium titles: 50-90 chars
Step 3 — Pick the pattern. Six patterns earn clicks (full detail in references/platform-hooks.md):
- A. Absurd-concrete-object ("Real LLM on a Game Boy Color")
- B. Confession + reversal ("I'm done with X")
- C. PSA / "admits" exposé ("Anthropic admits X")
- D. Specific number + impossible feat ("64-year-old problem solved")
- E. Naive question ("Forgive my ignorance but how is X better than Y?")
- F. "I asked X to..." setup ("I asked ChatGPT to imagine itself in retirement")
Step 4 — Front-load the punch. First 5-7 words decide whether anyone reads word 8. If the punch is "21-byte file," "21" goes in the first 7 words, not at the end.
Step 5 — Run the check. Three quick tests:
- Word 7 test: cover everything after word 7. Does the hook still stop the scroll?
- Specificity test: are there at least one specific number, name, or concrete object in the first 10 words?
- Pattern test: which of A-F is this? If you can't name one, it's a generic AI-style title. Rewrite.
Show full SKILL.md (245 more words)Show less
Banned title patterns
Do not write any of these. They are AI-style and underperform on every platform:
- "The Ultimate Guide to X"
- "X Things You Need to Know About Y"
- "Why X Matters" (unless paired with a specific number or scar)
- "How to X" (too soft on every platform)
- "Mastering X" / "Unlocking the Power of Y"
- Long subtitle-style titles with colons + clauses + em dashes (no em dashes period)
- "X: A Comprehensive [Guide / Look / Analysis]"
- "In Today's Fast-Paced World..."
Banned within the title
- Em dashes (—)
- Words from the [[assaf-voice]] banned list: leverage, transformative, etc.
- Hedging language: "might," "could," "perhaps," "some thoughts on"
- "Excited," "thrilled," "humbled" (the gratitude tells)
- Hashtags (in the title itself; OK below the body)
When to use this skill alongside [[assaf-voice]]
Always. Voice handles tone and sentence DNA. This skill handles the hook shape and length. Both fire for any published content.
For DM / email / internal note → voice skill only, skip this one. For LinkedIn post / Medium article / X thread / Reddit post / Substack → both fire.
Quality check before output
Before returning a title to the founder, verify:
- Char count fits the platform range
- First 5-7 words contain the punch
- At least one specific number, name, or concrete object
- Identifiable pattern from A-F
- No banned words
- No em dashes
- Passes [[assaf-voice]] voice checks (scar / contrast / specificity / theater)
If any check fails, rewrite before output. Never output 3+ candidates without a recommended pick named explicitly ("My call: #1").
