Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.00479 |
| Opus 5 | $0.00039 | $0.00239 |
| Sonnet 5 | $0.00016 | $0.00096 |
| Haiku 4.5 | $0.00008 | $0.00048 |
Grade A, and why
003-agents-installation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Embedded agents installer
Install a predefined set of embedded agent definitions from repository assets into a user-selected target directory. This is an interactive skill.
What is covered in this Skill?
- Interactive target selection (
.cursor/agentsor.claude/agents) - Deterministic copy of all embedded agents defined via XInclude from
assets/agents - Idempotent re-installation with clear overwrite reporting
Constraints
This skill installs only the embedded robot agents bundle and must ask for destination before writing files.
- MUST ask the user to choose
.cursor/agentsor.claude/agentsbefore installing - MUST copy all embedded agent files defined in
references/003-agents-installation.md - MUST preserve file names from the reference content and report overwrite actions
When to use this skill
- Install embedded agents
- Bootstrap .cursor/agents
- Bootstrap .claude/agents
- Copy robot agents
Workflow
- Choose destination
Ask exactly one question to choose .cursor/agents or .claude/agents and wait for an explicit answer before copying files.
Step constraints:
- Do not copy any file until destination is explicitly confirmed
- If destination is ambiguous, ask a clarification question
- Install embedded agents
Create the destination directory if needed, then copy all embedded agent files defined in the reference content, preserving filenames and warning before overwriting existing files.
- Report installation result
Return a concise checklist with selected destination, created/updated files, overwrite actions, and an optional verification command.
Reference
For detailed guidance, examples, and constraints, see references/003-agents-installation.md.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

003-agents-installation is a skill published in the GitHub repository majiayu000/claude-skill-registry (604 stars, last pushed today), licensed MIT. It adds 79 tokens to every session and 479 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
