What it does

Template Library is an agent skill from aspenkit/aspens. Bundled agents, commands, hooks, and settings that users install via aspens add, aspens doc init, and aspens save-tokens into their .claude/ directories

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Your CLAUDE.md stopped working at 200 lines. Generate scoped skill files from your import graph, auto-sync on every commit. Claude Code, Codex and OpenCode. The licence is MIT.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/template-library”

What it can do on your machine

Read from SKILL.md and the folder at commit 8dde826. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Template Library loads about 1.3k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 541 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

You are working on the template library — bundled agents, slash commands, hooks, and settings that users browse and install into their repos.

Domain purpose

aspens add <type> [name] copies curated templates into a consumer repo's .claude/ directories so users get working agents, slash commands, hooks, and settings without authoring them. The same template tree is reused by aspens doc init (hook installation, recommended agents) and aspens save-tokens (handoff tooling). Custom skills can also be scaffolded blank or LLM-generated from a reference doc.

Key Concepts

  • Four resource types for add: agent → .claude/agents, command → .claude/commands, hook → .claude/hooks. A fourth type skill is handled separately (not template-based).
  • Save-tokens templates: save-tokens.mjs is the runtime entry point for all three hook entry points (statusline, prompt-guard, precompact). Shell wrappers (save-tokens-*.sh) resolve project dir and delegate to the .mjs file. Slash commands (save-handoff.md, resume-handoff.md, resume-handoff-latest.md) provide user-invokable handoff management. These are installed by aspens save-tokens or aspens doc init --recommended, not by aspens add.
  • Codex-only restriction: add agent, add command, and add hook throw CliError for Codex-only repos. Skills work with both targets.
  • Target-aware skill commands: addSkillCommand and generateSkillFromDoc resolve the active target via resolveSkillTarget(config). Skill paths use target.skillsDir and target.skillFilename.
  • Backend-aware generation: generateSkillFromDoc uses runLLM() to dispatch to Claude or Codex based on config.
  • Hook templates (monorepo-aware): Shell hooks compute PROJECT_DIR from the script's own location (cd "$SCRIPT_DIR/../.." && pwd) and pass it as ASPENS_PROJECT_DIR to .mjs counterparts. Save-tokens shell hooks follow the same pattern.
  • Settings template quoting: Hook commands in settings.json are wrapped in double quotes for shell safety.
  • doc init hook installation (step 13): Generates skill-rules.json, copies hook files, generates post-tool-use-tracker.sh with domain patterns, merges settings.json with backup.
  • doc init --recommended extras (step 15): Copies all bundled agent templates to .claude/agents/ (skips existing), adds dev/ to .gitignore.
  • Template discovery: listAvailable() reads template dir, filters .md/.sh files, regex-parses name: and description:.
  • No-overwrite policy: addResource() skips files that already exist. Same for addSkillCommand.
  • Plan/execute gitignore: Adding plan or execute agents auto-adds dev/ to .gitignore for plan storage. doc init --recommended also ensures dev/ in .gitignore.
  • Base-skill warning for agents: addResource() prints a non-fatal yellow warning when installing an agent if .agents/skills/base/SKILL.md is missing, prompting the user to run aspens doc init. The agent still installs.

Critical files (purpose, not inventory)

  • src/commands/add.js — Entry point for aspens add; dispatches to resource copy, blank skill scaffold, or LLM skill generation.
  • src/templates/agents/*.md — Agent persona templates copied as-is into .claude/agents/.
  • src/templates/commands/*.md — Slash command templates (includes handoff commands installed by save-tokens).
  • src/templates/hooks/ — Hook scripts (skill-activation-prompt.{sh,mjs}, graph-context-prompt.{sh,mjs}, post-tool-use-tracker.sh, save-tokens.mjs, save-tokens-{statusline,prompt-guard,precompact}.sh).
  • src/templates/settings/settings.json — Default Claude Code settings with hook wiring; merged into the consumer repo's settings.
  • src/prompts/add-skill.md — System prompt for add skill --from <doc> LLM generation.

Critical Rules

  • Template files must contain name: <value> and description: <value> lines parseable by regex.
  • Only .md and .sh extensions are discovered by listAvailable(). .mjs files are copied by doc init and save-tokens directly, not by add.
  • The templates dir resolves from src/commands/ via join(__dirname, '..', 'templates') — moving add.js breaks template resolution.
  • Skill names are sanitized to lowercase alphanumeric + hyphens. Invalid names throw CliError.
  • Commands throw CliError for expected failures instead of calling process.exit().
  • Reference docs passed to add skill --from are truncated to 50,000 chars before being handed to the LLM.

When should I use Template Library?

Template Library fits situations like: agent Workflows work in your project.

How do I install Template Library in Claude Code?

Run `npx skills add aspenkit/aspens --skill template-library -a claude-code`. Or copy the skill folder (.agents/skills/template-library in aspenkit/aspens) into .claude/skills/template-library in your project. Claude Code loads it when a task matches its description.

How do I install Template Library in Codex?

Run `npx skills add aspenkit/aspens --skill template-library -a codex`. Or copy the skill folder (.agents/skills/template-library in aspenkit/aspens) into .agents/skills/template-library in your project. Codex loads it when a task matches its description.

Can I use Template Library in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aspenkit/aspens --skill template-library -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/template-library, .gemini/skills/template-library, .github/skills/template-library and .opencode/skills/template-library in your project.

What does Template Library need to run?

SKILL.md names no scripts, command-line tools or credentials: Template Library is instructions for the agent only.

Does Template Library access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Template Library safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

Template Library is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Template Library use?

About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
