At a glance

Safely validate, publish, and track a local SKILL.md directory across GitHub, Awesome Codex Plugins, HOL Registry, skills.sh, SkillsMP, LobeHub, ClawHub, and Cursor Directory.

  • The user asks to publish
  • SKILL.md covers Safety rules, Commands and Platform behavior
  • Calls python3 and npx; needs REGISTRY_BROKER_API_KEY
  • Synchronize an agent skill across marketplaces

What it does

Skill Sync Publisher is an agent skill from hashgraph-online/awesome-codex-plugins. Safely validate, publish, and track a local SKILL.md directory across GitHub, Awesome Codex Plugins, HOL Registry, skills.sh, SkillsMP, LobeHub, ClawHub, and Cursor Directory. Use when the user asks to publish, update, register, or synchronize an agent skill across marketplaces.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including assets (for example `.codex-plugin/plugin.json`, `.github/dependabot.yml` and `README.md`).

It works with GitHub. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • The user asks to publish
  • Synchronize an agent skill across marketplaces

Example prompts

  • “/skill-sync-publisher”

Requirements

  • Python 3
  • Node.js
  • A credential in REGISTRY_BROKER_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. 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

    Shell commands in SKILL.md call:

    • python3
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • REGISTRY_BROKER_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Sync Publisher loads about 789 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 323 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~789

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 Sync Publisher

Use the bundled CLI to preflight and synchronize one local skill directory. The source GitHub repository is canonical; registry entries are projections of that source. Read references/platform-matrix.md before working with a platform and references/security-policy.md when preflight reports a security finding.

Safety rules

  • Start with python3 scripts/sync.py preflight <skill-dir> or --dry-run.
  • Never collect or store passwords, tokens, cookies, or private keys.
  • Ask before the first submission to each platform. Persist choices per GitHub repository, skill path, and platform in the user state file, not the repo.
  • Require the user to complete login before running an authenticated identity check. A failed check blocks only that platform.
  • Show the exact diff and commit scope before GitHub commit/push.
  • Use official CLIs when available. For directory sites without a supported API/CLI, create a browser/manual handoff instead of inventing an endpoint.
  • Never touch unrelated dirty files, force-push, or roll back successful targets.

Commands

Run bin/skill-sync from the repository root:

text
bin/skill-sync init <skill-dir>
bin/skill-sync preflight <skill-dir>
bin/skill-sync layout --check
bin/skill-sync layout --write
bin/skill-sync sync <skill-dir> --dry-run --json
bin/skill-sync sync <skill-dir> --platform github,clawhub
bin/skill-sync sync <skill-dir> --resume
bin/skill-sync status <skill-dir> --refresh
bin/skill-sync reset-choice <skill-dir> <platform>
bin/skill-sync reset-all <skill-dir>
bin/skill-sync forget <skill-dir>

skills/skill-sync-publisher/ is the canonical skill content. Root SKILL.md and agents/openai.yaml are generated mirrors; use layout --write after a canonical change and layout --check in CI.

sync is confirmation-gated by default. --yes is intended for an already reviewed, authenticated automation job; it does not bypass platform choice or security blockers. The CLI returns non-zero if a selected platform fails or is blocked.

Platform behavior

  • GitHub: commit and push only the target skill files after confirmation.
  • Awesome Codex Plugins: create or update a PR only when a valid plugin manifest exists; ordinary skills are blocked unless explicitly projected.
  • HOL Registry: use the official npx @hol-org/registry quote/publish flow and require REGISTRY_BROKER_API_KEY before an authenticated publish.
  • ClawHub: use clawhub whoami, dry-run, then the manifest version as semver.
  • skills.sh, SkillsMP, LobeHub, Cursor Directory: verify public GitHub source and produce/check an index or browser handoff; planned is not success.

Never publish to an unselected platform, duplicate an open PR, or claim that a manual directory submission is complete before the user confirms it.
