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 | $0.00025 | $0.03445 |
| Opus 5 | $0.00013 | $0.01723 |
| Sonnet 5 | $0.00005 | $0.00689 |
| Haiku 4.5 | $0.00003 | $0.00345 |
Grade A, and why
daily-brief 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 9d 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 — 251 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Daily Brief
The founder's inbox will happily fill the day with other people's priorities. This is the fifteen minutes that decides whether today moved the quarter.
When to use
Weekday mornings, before opening email. Triggered automatically by
the local scheduler after setup-cadences. Otherwise run daily-brief by hand.
First-run branch
Use this branch when /founder-os-init invokes the skill and there is no prior
daily review. Read the persisted owner outputs; do not reconstruct a history
that predates YYYY-MM-DD. UNKNOWN is eligible work when it blocks the
financial baseline, not a reason to invent a normal-looking day.
| Persisted state | Selection rule | Required action |
|---|---|---|
first move available |
Cash and real burn are known and goals.md carries a first move. |
Make that first move ## The one thing, preserving its bet link. |
cash on hand unknown |
Runway is blocked by cash on hand. | Make resolve cash on hand ## The one thing and keep or add that item in ## Doing; it outranks a planned bet move. |
burn unknown |
Cash is known but real monthly burn is missing. | Make resolve real monthly burn ## The one thing and keep or add that item in ## Doing; it outranks a planned bet move. |
no prior review |
No daily commitment has started a clock. | Write Rotting: none — first run; no historical clock; do not assign ages to empty clients, pipeline or review files. |
first move unknown |
Financial inputs are known but no owner-persisted first move exists. | Write the blocking first move as UNKNOWN, keep activation incomplete, and do not invent work. |
Write the same owned daily-review headings as every later brief:
# YYYY-MM-DD
## The one thing
[<existing queue id, or new id from queue>] <financial blocker or first move>
## Rotting
none — first run; no historical clock
## The trade
<what the selected blocker or move displaces today>
## Triage
none
When the cash or burn item already exists in queue.md, reuse its id and move
it through queue; do not create a duplicate. The Chief of Staff owns both the
queue and daily review, so this is an ordinary owner-safe transition. On the
next day, leave this branch and apply the recurring Steps below to actual
history.
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.

daily-brief is a skill published in the GitHub repository msolecki/founder-os (4 stars, last pushed 6d ago), licensed MIT. It adds 25 tokens to every session and 3,445 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.
