What it does

Fix My Opening Line is an agent skill from aiskillstore/marketplace. Diagnose why a post's opening line is not stopping anyone, and rewrite it from several genuinely different angles. Use when someone says a post flopped, asks for a better hook, first line or opener, asks why nobody read something, or is stuck on how to start. Do not use it to write the whole post, and do not promise that a new opening will make a post perform.

Its SKILL.md is about 940 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. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Someone says a post flopped
  • Asks for a better hook
  • Asks why nobody read something
  • Is stuck on how to start

Example prompts

  • “/fix-my-opening-line”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. read the opening as a stranger would
  2. find what was already there
  3. rewrite from different angles, not different wordings
  4. keep it honest

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 Opening Line loads about 940 tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 569 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~940

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 569 words (~940 tokens).

“On both Twitter and LinkedIn most people see the first line and nothing else. The rest of the post is only read by people the first line already convinced. So a post that "did not work" is usually a first…”
