What it does

Skild is an agent skill from Peiiii/skild. Skill package manager for AI Agents — install, manage, and publish Agent Skills.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `commands.md`, `skillsets.md` and `troubleshooting.md`).

The repository describes itself as: The npm for Agent Skills — Discover, install, manage, and publish AI Agent Skills with ease. The licence is MIT.

Example prompts

  • “/skild”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Search via /discover and shortlist results by description/tags.
  2. Confirm with the user and pick the best match.
  3. Install using the provided install command (or alias).
  4. Manage using skild list / info / update / uninstall / sync.

What it can do on your machine

Read from SKILL.md and the folder at commit 42d6316. 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:

    • curl
    • npm

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • registry.skild.sh

    Also links to:

    • hub.skild.sh
    • skild.sh

    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

Skild loads about 1.4k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

skild

skild is the package manager for Agent Skills — like npm, but for AI agents.

When to Use

Use this skill when:

  • Installing new capabilities for AI agents
  • Managing installed Skills (list, update, uninstall)
  • Publishing Skills to share with the community
  • Searching or discovering new Skills

Agent Search & Discovery (Skild Index)

When an agent needs to find Skills from the Skild index (registry + linked + auto catalog), use the Registry API:

bash
# Unified discovery (registry + linked skills)
curl "https://registry.skild.sh/discover?q=<query>&limit=20"

# Resolve a short alias (optional)
curl "https://registry.skild.sh/resolve?alias=<alias>"

Notes:

  • Prefer alias if present; it provides the shortest install command.
  • Use the returned install string directly (quotes may appear when a #ref is required).
  • /discover supports pagination and filtering:
    • cursor=<nextCursor> for pagination
    • sort=updated|new|downloads_7d|downloads_30d|stars|stars_30d
    • skillset=true|false and category=<id> to narrow results
  • If you need to browse linked items only:
    • https://registry.skild.sh/linked-items?limit=20
  • CLI skild search uses the same unified index.
  1. Search via /discover and shortlist results by description/tags.
  2. Confirm with the user and pick the best match.
  3. Install using the provided install command (or alias).
  4. Manage using skild list / info / update / uninstall / sync.

Push to Git Repos (Registry-free)

Use skild push to sync a Skill into a Git repository and push changes.

bash
# Push to GitHub by owner/repo
skild push owner/repo --dir ./my-skill

# Set a default repo (omit <repo> afterwards)
skild config set push.defaultRepo owner/repo
skild push --dir ./my-skill

# Push to a local repo path
skild push ~/work/skills-repo --local --dir ./my-skill

# Push to a specific subdirectory
skild push owner/repo --dir ./my-skill --path skills/my-skill

# Push to a branch (or append #branch to the repo)
skild push owner/repo#dev --dir ./my-skill

Notes:

  • The target path defaults to skills/<skill-name> derived from SKILL.md.
  • Target path cannot be the repo root.
  • The command clones, commits, and pushes to the remote branch.
  • For owner/repo, skild tries SSH first and falls back to HTTPS if SSH auth fails.
  • skild push <repo> always overrides the default repo.
  • You can also set SKILD_DEFAULT_PUSH_REPO to override the default repo per shell.
