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.

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 | $0.00053 | $0.00482 |
| Opus 5.5 | $0.00021 | $0.00193 |
| Sonnet 5.5 | $0.00011 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
Grade A, and why
monolean-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 2d 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
Monolean Help
Display this reference card when invoked. One-shot, do NOT change mode, write flag files, or persist anything.
Levels
| Level | Trigger | What change |
|---|---|---|
| Lite | /monolean lite |
Build what's asked, name the lazier alternative in one line. |
| Full | /monolean |
The ladder enforced: YAGNI → stdlib → native → one line → minimum. Default. |
| Ultra | /monolean ultra |
YAGNI extremist. Deletion before addition. Challenges requirements before building. |
Level sticks until changed or session end.
Skills
| Skill | Trigger | What it does |
|---|---|---|
| monolean | /monolean |
Lean mode itself. Simplest solution that works. |
| monolean-audit | /monolean-audit |
Whole-repo audit for over-engineering. Ranked findings. |
| monolean-debt | /monolean-debt |
Harvest monolean: comments into a debt ledger. |
| monolean-help | /monolean-help |
This card. |
Claude Code uses the slash-command forms above.
Deactivate
Say "stop monolean" or "normal mode". Resume anytime with /monolean.
/monolean off also works.
Configure Default Mode
Default mode = full, auto-active every session. Change it:
Environment variable (highest priority):
export MONOLEAN_DEFAULT_MODE=ultra
State file (.monomind/state/monolean-mode):
Write the mode name to this file. Monomind reads it on session start.
Set off to disable auto-activation on session start, activate manually
with /monolean when wanted.
Resolution: env var > state file > full.

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.
