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.

Show its rules and text
We split this skill into the rules it gives an agent
27 rules. 0 are common, 22 are distinctive, and 5 are very specific to this project.

Common
Most of the 17 edited versions we read keep these.
22
Distinctive
This author's own choices. Worth a look.

“Common” is measured: kept by at least 6 in 10 of the 17 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
Skill Sync
Source: https://github.com/catalystsystemslab/codex-skill-sync/tree/main/skill-sync
Keep installed skills and Codex plugins current. doctor is read-only setup
diagnostics. check, update, and run all all start the same inventory and
mapping flow.
Language
Reply in the user's language by default.
- If the user writes in English, respond in English.
- If the user writes in Chinese, respond in Simplified Chinese.
- If the user mixes English and Chinese, use the dominant language.
- Keep commands, file paths, JSON keys, status values, and shell commands unchanged.
- Translate explanations, summaries, warnings, and recommendations.
Important label translations:
- Official / 官方
- Community / 社区
- Needs Setup / 需要设置
current/ 已是最新update_available/ 有可用更新updated/ 已更新skipped/ 已跳过failed/ 失败
Start Here
For check, update, and run all, first list what is installed:
python3 <skill-dir>/scripts/update_codex_assets.py --inventory --json --report skill-update-report.jsonShow the result as three groups. Translate internal JSON groups this way:
official-> Officialnon_official-> Communityunmapped-> Needs Setup
Blank repo means the source is not confirmed. Do not guess.
Beginner Response Style
Most users do not know Git, JSON, branches, or subpaths.
When showing inventory:
- Explain each group in plain language.
- Do not show raw JSON unless the user asks.
- Recommend the safest next action.
- Ask one decision at a time.
When mapping:
- Say that public GitHub search may use the skill name and description.
- Never ask the user to edit JSON manually unless they choose advanced mode.
- If editing the manifest, preserve existing entries and only add confirmed mappings.
- Show exactly what will be saved before saving it.
Before apply:
- Summarize what will change.
- List skipped skills separately.
- Remind the user that backups will be created.
- Ask for explicit confirmation.
Commands
For doctor:
- Run read-only diagnostics.
- Explain warnings in plain language.
- Recommend the safest next action.
python3 <skill-dir>/scripts/update_codex_assets.py --doctor --report skill-doctor-report.jsonFor check:
- Run inventory.
- If Needs Setup has anything, ask whether to map repos now or skip mapping for this run.
- If the user maps repos, save only confident matches.
- Run a dry update check. Do not apply.
python3 <skill-dir>/scripts/update_codex_assets.py --json --report skill-update-report.jsonFor update or run all:
- Run inventory.
- If Needs Setup has anything, ask whether to map repos now or skip mapping for this run.
- If the user maps repos, save only confident matches.
- Show the repo list with blanks for uncertain repos.
- Ask for update confirmation.
- Apply updates.
- After the first successful update, ask whether to create a weekly check automation.
python3 <skill-dir>/scripts/update_codex_assets.py --apply --json --report skill-update-report.jsonMapping
Use ~/.codex/skill-sources.json as the default saved mapping so the user does
not need to map the same skills again. If the user supplies another manifest,
use that instead.
Only confirmed repo mappings persist. If the user skips mapping for this run, do not mark those skills local unless they explicitly say the skill is private or local-only.
If the user chooses Map, public GitHub/web search is already part of the task. Proceed with search tools and only ask again if the runtime blocks network access or a repo match is uncertain.
Read references/manifest.example.json before editing a manifest.
For each Needs Setup skill:
- Search public GitHub first. Use the exact skill name plus unique words from its frontmatter or heading.
- Prefer the upstream public repo with strong evidence: exact
SKILL.mdmatch, same description/name, active repo, and visible community use such as stars. - Do not map Needs Setup skills to
catalystsystemslab/<skill>,isaaclim/<skill>, or another user/org mirror unless the installed skill itself names that repo as its source or the user confirms it. - Trust a repo only when it contains that skill's
SKILL.mdat the repo root or a clear subfolder. - Save confirmed matches with
url,branch, andsubpath. - If unsure, leave the repo blank or ask the user for the link.
- Mark private/local skills as local:
{ "name": "my-private-skill", "root": "~/.codex/skills", "kind": "local" }Status Words
current: already okay.update_available: update found, not applied yet.updated: replaced after backup.skipped: unknown source: needs a repo link or local marking.failed: inspect network, auth, branch, or subpath.
Safety
- Default to dry-run unless the user clearly asks to update.
- Back up before replacing a skill folder.
- Never overwrite Needs Setup skills.
- Do not migrate a skill to a similar repo without confirmation.
- The script replaces whole skill folders; it does not merge local edits.
- Unsafe remote skill trees must be reported as failed and never installed.
- Do not ask the user to override unsafe symlink or size failures.
- Codex plugin updates are Codex-only.
Automation
Offer weekly check automation only after a successful update. Weekly is the default; bi-weekly is fine for stable setups.
Weekly automation must default to dry-run check mode. Do not create an
automation that runs --apply unless the user explicitly asks for automatic
updates and confirms they understand it will replace mapped skill folders.
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.

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.
