Package Library

Agent-native catalog and installer for all armory package types. Provides browsing, searching, installing, updating, syncing, and removing packages directly within an agent session.

Variables

• **ARMORY_REPO**: `Mathews-Tom/armory`
• **ARMORY_BRANCH**: `main`
• **ARMORY_CATALOG_URL**: `https://raw.githubusercontent.com/{ARMORY_REPO}/{ARMORY_BRANCH}/manifest.yaml`
• **DEFAULT_INSTALL_DIR**: `~/.claude/`
• **CATALOG_CACHE_PATH**: `/tmp/armory-manifest.yaml`
• **CATALOG_CACHE_TTL**: `600` (seconds)

Command Reference

| Command | Cookbook | Purpose | | ----------------------------------- | ---------------------- | ------------------------------------------------------------------------ | | `/library list` | `cookbook/list.md` | Show all packages with type, version, installed status, update available | | `/library list --type <type>` | `cookbook/list.md` | Filter listing by package type (skill, agent, hook, rule, etc.) | | `/library use <name>` | `cookbook/use.md` | Pull a package from armory (auto-detects type from manifest) | | `/library search <keyword>` | `cookbook/search.md` | Keyword search across all package types, names, and descriptions | | `/library search --category <name>` | `cookbook/search.md` | Filter search by category (development, review, security, etc.) | | `/library sync` | `cookbook/sync.md` | Re-pull all installed packages that have updates | | `/library info <name>` | `cookbook/info.md` | Show full detail for a package (type, version, tags, category) | | `/library update` | `cookbook/update.md` | Check all installed packages for version bumps (dry-run sync) | | `/library remove <name>` | `cookbook/remove.md` | Remove an installed package | | `/library profiles` | `cookbook/profiles.md` | Show available install profiles with package counts |

Cookbook Dispatch

User commands are routed to the corresponding cookbook file based on the subcommand. When a `/library` command is received, extract the subcommand (the first token after `/library`) and load the matching cookbook file from the `cookbook/` directory relative to this skill. The cookbook file contains the full execution procedure for that operation.

For example, `/library use commit-standards` dispatches to `cookbook/use.md` with `commit-standards` as the package name argument. `/library list --type agent` dispatches to `cookbook/list.md` with `--type agent` as the filter.

If the subcommand does not match any known cookbook, report the error and list the valid subcommands from the table above.

Type Detection

When `/library use <name>` is called, determine the package type by searching all sections of the manifest (`packages.skills`, `packages.agents`, `packages.hooks`, etc.). The first section containing a matching `name` entry determines the type. Use the type to:

1. Resolve the correct source path: `{type_dir}/{name}/` 2. Determine the install target: `~/.claude/{install_subdir}/` 3. Choose the install method: directory copy or body-only extraction

Behavioral Notes

• All bash operations must use absolute paths. Never `cd` into temp dirs.
• Fetch uses a 3-tier fallback chain: sparse checkout, then `gh api`, then `curl`. Attempt each in order; proceed to the next only on failure.
• Cache lives in `/tmp/` with a 10-minute TTL. A missing cache file is treated as expired (triggers a re-fetch), not as an error.
• The catalog is read from `manifest.yaml` on GitHub (at `ARMORY_CATALOG_URL`), not from a separate catalog file. This is the same manifest format used by the armory repository.
• All package type sections share the same entry format: `name`, `version`, `description`, `path`, `source`, plus optional `tags`, `category`, `difficulty`.
