What is legal-update?

A command for refreshing the legal and compliance sources used for a chosen jurisdiction. It checks whether sources have changed and records when they were last checked.

Use it for quarterly source reviews or pre-memo checks, including identifying stale sources and updating their check dates.

It reduces the risk of relying on legal references that are out of date, especially before writing a client-facing legal memo.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.01054
Opus 5	$0.00020	$0.00527
Sonnet 5	$0.00008	$0.00211
Haiku 4.5	$0.00004	$0.00105

Security

Grade A, and why

legal-update 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.

Legal & Compliance Update

Quarterly refresh of the loaded jurisdiction's source set. Walks each source, prompts you to web-search it, captures any material changes, and updates last_checked_on: dates so the skill stops flagging the source as stale.

Procedure

Verify install. If core/identity.md does not exist, reply: Founder OS not set up here. Say "set up Founder OS" first. and stop.
Read jurisdiction. Open core/identity.md and find the jurisdiction: field. If missing, reply: No jurisdiction set. Say "set up legal" first. and stop.
Open sources.yml. Read skills/legal-compliance/references/<jurisdiction>/sources.yml. If missing, reply: No source set loaded for <jurisdiction>. Say "set up legal" to create the scaffold, or "add a legal source" to add sources directly. and stop.
Identify stale sources. Today's date minus each source's last_checked_on:. Anything >180 days old is "stale". Anything >90 days old is "warming". Anything ≤90 days is "fresh".
Show the user the audit:

Source freshness audit for <jurisdiction> as of <today>:

Stale (>6 months - refresh now):
  - <source-key>: <name>, last checked <date>, <N> days ago
  - ...

Warming (3-6 months - refresh recommended):
  - <source-key>: <name>, last checked <date>
  - ...

Fresh (<3 months - no action):
  - <source-key>: <name>, last checked <date>
  - ...

Walk each stale source one at a time. Ask: "Refresh <source-key> ()? Options: yes / skip / mark-checked-no-changes / drop-source"
- yes: WebFetch the source URL. Look for material changes (new amendments, ministerial decisions, threshold updates, fee changes). Show the user a summary: "Found / did not find material changes since <last_checked_on>." If material changes are found, ask: "Add a one-line note to sources.yml's notes: field for this source AND update the relevant domain file's '## Material Changes Since' block? (yes / no)". If yes, do both edits. Update last_checked_on: to today's date.
- skip: leave as-is, move to next source.
- mark-checked-no-changes: update last_checked_on: to today's date without web-fetching. Use when the user has already verified the source themselves.
- drop-source: the source is no longer authoritative. Remove the entry from sources.yml after a confirmation prompt: "Drop <source-key> permanently? Will not auto-restore. (yes / no)"

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.
