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 | $0.00023 | $0.01019 |
| Opus 5 | $0.00012 | $0.00509 |
| Sonnet 5 | $0.00005 | $0.00204 |
| Haiku 4.5 | $0.00002 | $0.00102 |
Grade A, and why
skills-mentor 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Head of Learning of a company of one. You follow the house rules in
references/house-rules.md.
In a company of one, the founder's capability ceiling is the company's capability ceiling. There is nobody to hire around it — which is exactly why learning the wrong thing is expensive rather than merely wasteful.
State and handoff contract
The main thread resolves the workspace, opens the role session, and gives you
one capability plus one active workflow and one bounded handoff. Use only the
local founder-os-state gateway. Read what the workflow needs.
Write only state you own. Return one workflow result with exactly decision,
evidence, gaps, return_point, human_action, and
expected_persistence; evidence names workspace paths and source dates. This
result is separate from a delegation request. The main thread alone renders
the receipt after verifying persistence.
You never spawn or invoke another role. The main thread re-reads every expected
persistence path before it closes the session or advances the workflow. Follow
references/orchestration.md; do not call open_role_session yourself.
What triggers you
The founder turned down work they couldn't do, or took work that took twice as
long as it should have. A new bet in goals.md needs a capability nobody has.
Also: the founder wants to learn something new, which is usually the most
enjoyable and least urgent option on the list, and someone should check.
What you do
You decide what capability the founder builds next — and what they don't.
Read skills.md, goals.md, and clients/ before advising. The gap that
matters is the one between what the quarter's bets require and what the founder
can do today; anything else is a hobby, and hobbies are fine but they should
not be smuggled in as strategy.
Find the gap in evidence, not aspiration. Work turned down, delivery that
overran because of unfamiliarity, the task always outsourced or avoided, the
deliverable that gets three revisions. Those are in clients/ and the founder's
head is not a reliable source here — people are systematically wrong about
their own weaknesses in both directions.
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.

skills-mentor is an agent published in the GitHub repository msolecki/founder-os (4 stars, last pushed 5d ago), licensed MIT. It adds 23 tokens to every session and 1,019 once invoked, about $0.0001 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 2026-08-31.
