Declarative agent skill management.

skeel reads a desired-state manifest and applies it through gh skill.

• Desired state: declare skill sources in one YAML file
• Inventory, dry run, and diff: list selected skill inventory, preview commands, and compare managed skills against what's installed locally
• Add, apply, and update: edit desired state, reconcile installed skills with live progress, and update declared installed skills
• Target flags: choose local or global scope from the CLI
• JSON output: pass --json for one machine-readable object on stdout

Run skeel directly with uvx:

uvx skeel

Default path: .agents/skills.yaml in project scope, ~/.agents/skills.yaml in user scope.

sources:
  anthropics/skills:
    - skill-creator
  mavam/quarto-brief:
  openclaw/gogcli:
    - gog
  tenzir/skills:
    pin: main
    skills:
      - tenzir-ecs

An empty value installs all skills from a source. A list is the common form for selected skills. Use a nested mapping only for source options, such as pin or custom install commands.

By default, skeel uses project scope: .agents/skills.yaml and .agents/skills in the current working directory. Use -g or --scope user for global installs into ~/.agents/skills:

uvx skeel -g apply

Use --manifest (-m) for a non-default desired-state manifest:

uvx skeel --manifest ./skills.yaml apply --dry-run

Scope selects the base directory for the implicit manifest and managed skill directory: project scope uses the current working directory and user scope uses $HOME. Use -a or --all with commands that can operate on both scopes. If the implicit manifest does not exist, apply, diff, list, and update are no-ops; add creates the manifest. Use --manifest or SKEEL_MANIFEST to use a manifest from another path. Because an explicit manifest path is not scoped, -a and --all are rejected when --manifest or SKEEL_MANIFEST is set.

By default, every command operates on project scope. Use -g, --user, --global, or --scope user to operate on user scope. Use -a or --all to operate on both project and user scopes for diff, list, apply, remove, and update when using the implicit manifests.

Human output is consistent across commands: the first column is the action marker, the second column is a muted scope glyph (★ for project, ⌂ for user), followed by the skill name, the source, and a muted suffix for versions, paths, or diagnostic details.

For scripts, pass --json to add, apply, diff, list, path, remove, or update to emit one machine-readable object on stdout.

Show installed skills together with manifest status. Missing manifest skills are marked with ✘; installed skills that are not declared in the manifest still appear in the inventory and include "managed": false in JSON output. Rows are tagged with their scope glyph. Sources declared without a skill list expand to the installed skills from that source instead of showing *.

uvx skeel list -a

✔︎ ★ tenzir-docs tenzir/skills main@a5d04ab
✘ ★ gog openclaw/gogcli
✔︎ ⌂ skill-creator anthropics/skills main@3cf9a8d
✔︎ ⌂ wrangler cloudflare/skills main@45cc198
✔︎ ⌂ clacks
✔︎ ⌂ quarto-brief mavam/quarto-brief main@e89c555

Compare desired state with installed skills. + rows would be installed by apply; - rows would be removed.

uvx skeel diff

+ ★ wrangler cloudflare/skills
+ ★ vectorize cloudflare/skills
- ★ obsolete-skill installed
- ★ old-experiment installed

Reconcile installed skills with the manifest. Missing skills are installed and extra skills are removed. Use --reinstall to run every manifest installer without diffing first, or apply <source> [skill] to target one source. A selector that does not match the manifest exits with an error.

uvx skeel apply --dry-run

↳ gh skill install cloudflare/skills wrangler --allow-hidden-dirs --dir .agents/skills --force
↳ gh skill install cloudflare/skills vectorize --allow-hidden-dirs --dir .agents/skills --force
↳ rm -rf .agents/skills/obsolete-skill

uvx skeel apply

+ ★ wrangler cloudflare/skills
+ ★ vectorize cloudflare/skills
- ★ obsolete-skill

Update installed skills that are represented by the manifest. Each installed skill is checked independently, and remote update checks run in parallel. Pass a source, or a source and skill, to update only that manifest selection. A selector that does not match the manifest exits with an error.

uvx skeel update
uvx skeel update tenzir/skills
uvx skeel update tenzir/skills tenzir-docs
uvx skeel update -a

✔︎ ★ teach mattpocock/skills main@975430f
✔︎ ★ tenzir-docs tenzir/skills main@f3842c1
✔︎ ★ clacks downstairs-dawgs/clacks
✘ ★ broken-skill broken/source

Pinned GitHub entries are updated by resolving the configured pin and refreshing installed files when the source changes. Skills installed by gh skill include provenance in SKILL.md frontmatter, so future updates can track them directly.

Upsert a source or source/skill entry into the manifest. Omit the skill to select all skills from the source. Pass --apply to reconcile immediately.

uvx skeel add tenzir/skills tenzir-docs@main

✔︎ ★ tenzir-docs tenzir/skills .agents/skills.yaml

uvx skeel add mavam/quarto-brief --dry-run

↳ mavam/quarto-brief .agents/skills.yaml

Remove an unambiguous skill name from the selected manifest. Pass --apply to reconcile immediately. A selector that does not match the manifest exits with an error.

add and remove are intentionally asymmetric: adding starts from a source because skeel needs to know where to install from, while removing starts from a skill because that is the common user intent. Use --source only to disambiguate or remove a whole source.

uvx skeel remove tenzir-docs

✔︎ ★ tenzir-docs tenzir/skills .agents/skills.yaml

When multiple sources declare the same skill name, disambiguate with --source:

uvx skeel remove tenzir-docs --source tenzir/skills

Omit the skill to remove the whole source selected by --source:

uvx skeel remove --source mavam/quarto-brief --dry-run

↳ mavam/quarto-brief .agents/skills.yaml

Print the manifest path that skeel would use for the selected scope.

uvx skeel path

.agents/skills.yaml

Use -a to print both implicit paths:

uvx skeel path -a

project .agents/skills.yaml
user    /Users/alice/.agents/skills.yaml

When applying, skeel delegates placement to gh skill with:

gh skill install <repo> <skill> --dir .agents/skills --force

The target directory is derived from scope: project scope uses the current working directory and user scope uses $HOME. A bare GitHub source installs all skills from that repository:

sources:
  mavam/quarto-brief:

which runs:

gh skill install mavam/quarto-brief --all --dir .agents/skills --force

For installers that are not backed by gh skill, provide source-level install commands under the source key. Skeel runs those commands as the complete install command set:

sources:
  slack-clacks/clacks:
    skills:
      - clacks
    install:
      - uvx --from slack-clacks clacks skill --mode universal --force

To add a GitHub source from the CLI, use the same positional shape as gh skill install:

uvx skeel add tenzir/skills tenzir-docs@main
uvx skeel remove tenzir/skills tenzir-docs
uvx skeel add mavam/quarto-brief --apply
