Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00027 | $0.00327 |
| Opus 5.5 | $0.00011 | $0.00131 |
| Sonnet 5.5 | $0.00005 | $0.00065 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
lean-help 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 1mo 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
/lean-help
Explain the lean-coach plugin. Drive this with the help skill.
Topic: $ARGUMENTS (a skill, command, agent, role, or concept like "canvas", "risk", "product/market fit"). If empty, explain everything.
Procedure
- No topic → give the full overview from the
helpskill: the "one coach, many hats" concept, the guide roles and role-play personas, every skill, the/lean-*commands, thelean-mentoragent, and the.lean/workspace — each in a line — then point todocs/and suggest a starting move. - A topic → resolve it to the matching skill/command/agent/role (see the mapping in the
helpskill), read that item's${CLAUDE_PLUGIN_ROOT}/docs/<item>.md(or itsSKILL.md), and explain just that one: what it does, when it triggers, how to invoke it on both Claude Code and Codex (/lean-coach:<skill>), and what it produces. If ambiguous, list close matches and ask.
Lead with a one-line answer, keep it skimmable, and link rather than dumping file contents.
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.

lean-help is a command published in the GitHub repository TimboGP/timbogp-marketplace (3 stars, last pushed 13d ago), licensed MIT. It adds 27 tokens to every session and 327 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
