What it does
Ig Caption is an agent skill from Jakeschincariol/instagram-agent-skill. 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.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `caption.py`).
It sits in Writing & Content, covering Social media posts and Linting and formatting. The repository describes itself as: Thirteen Claude skills that run an Instagram account: Reels off 26 scored hook formulas, a viral research skill, a caption linter, and a humanizer. Free, MIT. The licence is MIT.
When your agent uses it
- The user says write the caption
- What do I put in the description
- A carousel ready and needs the text
- Asks about hashtags
Example prompts
- “... more”
- “write the caption”
- “caption this”
- “/ig-caption”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Decide Job A or Job B and say which.
- Draft it.
- Run /ig-human on it. Captions are short, so slop is louder here than
- Run caption.py with the user's search terms. Fix every FAIL. Decide on
- Print the copy-ready block, then the receipt
What it can do on your machine
Read from SKILL.md and the folder at commit d03c56b. 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
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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
Ig Caption loads about 1.2k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 589 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.

- description
- 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.
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.
Show full SKILL.md (262 more words)Show less
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.
