Skill88 starsChanged 2 months agoMITView on GitHub
Write the Instagram caption - the line that survives the "... more" cut, the body, the single ask, the search terms and the three hashtags - and lint it before it goes out. Use when the user says "write the caption", "caption this", "what do I put in the description", has a reel or a carousel ready and needs the text, or asks about hashtags.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
5 rules. 0 are common, 3 are distinctive, and 2 are very specific to this project.
0
Common
Most of the 7 edited versions we read keep these.
3
Distinctive
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 37
Ask which one you are writing.
- Distinctive: line 78
Ask for two or three of those terms, then pass them to the linter:
- Distinctive: line 92
Write the first comment separately: if there is a link. Say so in the receipt.
- Very specific: line 103
Run /ig-human on it. Captions are short, so slop is louder here than anywhere else in the pack.
- Very specific: line 105
Run caption.py with the user's search terms.
“Common” is measured: kept by at least 6 in 10 of the 7 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
ig-caption
One tool lives in this folder and it runs:
python3 caption.py caption.txt
python3 caption.py caption.txt --keywords "client proposals,agency pricing"It prints the caption the way the feed prints it: the first 125 characters in a box, everything else behind the tap. Read that box before you read anything else you wrote.
First, decide which job this caption has
This is the decision that ruins captions when it is skipped.
Job A: the video already hooked them. A Reel carries its own hook in the first two seconds, spoken and on screen. The caption is not a second hook and competing with the video is how you lose both. Its job is the ask, the context that makes the ask make sense, and the words people search.
Job B: the caption is the content. A photo, a single image, a carousel cover that opens a loop. Here line one is the hook and it works exactly like a Reel hook: concrete, short, and cut off at a cliff rather than mid-clause.
Ask which one you are writing. If the user has a Reel with a strong hook, write A and say why.
The shape
Line 1 125 characters of visible space. Job A: the ask, plainly.
Job B: the hook.
Never a greeting, never a hashtag, never an emoji as the first
character.
Body short paragraphs, one line of white space between each. Two to six
of them. This is where the search terms live.
The ask one. Comment a keyword, save it, or DM. One.
Hashtags up to five, on their own line at the bottom, or none.Limit is 2,200 characters and almost nothing needs 2,200. A caption that earns the tap and then delivers 600 characters beats one that delivers 1,800.
Hashtags, honestly
Hashtags are not a reach lever any more, and the platform has now said so with a product change. Instagram capped hashtags at five per post on 18 December 2025, down from thirty, telling creators that "using fewer (up to 5) more targeted hashtags, rather than many generic ones" performs better. Adam Mosseri had already said in February 2025 that hashtags do not work to increase reach and are a label, not a distribution lever.
So: up to five, specific, as topic labels. If the user has a block of twenty saved in their notes app, that block is now dead weight and the linter will fail it.
#viral, #fyp, #explorepage, #foryou describe nothing. Cut them.
Search terms matter more than hashtags now
Instagram search reads the caption text. So the phrase the user wants to be found for goes in the caption as a phrase a human would type, in a sentence that reads normally. "Client proposals" as words in line three, not "#clientproposals" in a block at the bottom.
Ask for two or three of those terms, then pass them to the linter:
python3 caption.py draft.txt --keywords "client proposals,agency pricing"Rules
- No link in the caption. Captions are not clickable. A URL in the body is dead text that says "I do not use this platform". Bio or DM.
- One ask. Two asks is the same as none.
caption.pycounts them. - The keyword ask needs a keyword people can type. One word, no spaces, no
emoji, and say it out loud in the video too.
Comment CONTRACTworks.Comment "the contract guide"does not. - Write the first comment separately if there is a link. Say so in the receipt.
- Emoji as punctuation, not decoration. The linter flags anything over 4 per 100 characters.
- Alt text is worth 20 seconds. For carousels and photos, write it. It is read by screen readers and by Instagram.
The loop
- Decide Job A or Job B and say which.
- Draft it.
- Run
/ig-humanon it. Captions are short, so slop is louder here than anywhere else in the pack. - Run
caption.pywith the user's search terms. Fix every FAIL. Decide on every WARN out loud rather than silently. - Print the copy-ready block, then the receipt:
CAPTION READY
job: A - the reel carries the hook
visible: 118 of 125 characters used before the cut
ask: one, comment CONTRACT
hashtags: 3
search: "client proposals" in line 3, "agency pricing" in line 5
linter: READYNothing is posted. The user pastes it.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
