self-diligence

self-diligence is a command for Claude Code from ARCASSystems/FounderOS. It costs 56 tokens per session (357 once invoked), scanned A, original, MIT.

A report of changes since the previous Founder OS session, where Founder OS is a file-based system for organising a founder’s work and decisions. It compares the current state with a saved session timestamp.

In plain words
What is it for?
Use it when returning to Founder OS to see elapsed time, added brain-log entries, decayed flags, and newly overdue commitments.
Why use it?
It helps you catch up on new log entries, ageing warnings, and overdue commitments without rereading everything.

Token cost

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.

Security

Grade A, and why

self-diligence 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 5d 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

Founder OS self-diligence

Run the self-diligence skill at skills/self-diligence/SKILL.md end to end.

Procedure

  1. Read skills/self-diligence/SKILL.md.
  2. Run python scripts/check-identity-ready.py. If it exits 1, surface the line verbatim and stop.
  3. If $ARGUMENTS names a business, scope the read to it. If empty and companies/ holds more than one, ask which. If empty and there is one, use it.
  4. Read the file list in the skill. Do not ask the founder for anything already written down.
  5. Produce the output block in the skill exactly: scores, per-dimension, SWOT, critical challenges, disclosed gaps, and the questions.
  6. Read-only. Write nothing unless the founder asks for the read to be saved.

Rules

  • Never invent a fact or a number. Anything not grounded in the files becomes a question to the founder.
  • No evidence is not a middling score. Report it as unscored with the question that would fix it.
  • No em dashes or en dashes. No banned words.
Changes

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.
