What it does
What Worked is an agent skill from aiskillstore/marketplace. Work out what a person's best-performing Twitter or LinkedIn posts have in common, and turn that into what to write next. Use when someone asks why a post did well or badly, what their best posts have in common, what to write more of, or wants their recent posts reviewed against their numbers. Do not invent engagement numbers, and do not use this to analyse someone else's account.
Its SKILL.md is about 1k 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. It works with X (Twitter). The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Someone asks why a post did well
- What their best posts have in common
- What to write more of
- Wants their recent posts reviewed against their numbers
Example prompts
- “/what-worked”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- get the numbers
- compare like with like
- say what the winners share
- turn it into the next post
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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
What Worked loads about 1k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 620 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 620 words (~1,011 tokens).
“The useful version of this is specific to one person's actual posts. General content advice is free everywhere and worth what it costs.”
