What it does
Fix My Last Line is an agent skill from aiskillstore/marketplace. Work out whether a tweet's last line is earning its place, and usually delete it. Use when a tweet feels flat at the end, when someone asks how to close a tweet, when they want a call to action on one, or when a draft trails off without landing. Do not add engagement bait, do not promise replies, and do not treat a missing ending as a problem needing a solution.
Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).
It sits in Writing & Content, covering Social media posts. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- A tweet feels flat at the end
- Someone asks how to close a tweet
- They want a call to action on one
- A draft trails off without landing
Example prompts
- “/fix-my-last-line”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- run the delete test first
- name what the last line is doing
- when an ending genuinely belongs
- never do these
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. 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
Fix My Last Line loads about 952 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 604 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 604 words (~952 tokens).
“Most advice about endings comes from long-form writing, where a post has room to build and a reader who has committed. A tweet has neither. It is one unit, read in about a second, and the last line is the…”
