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 | $0.00045 | $0.01109 |
| Opus 5 | $0.00023 | $0.00554 |
| Sonnet 5 | $0.00009 | $0.00222 |
| Haiku 4.5 | $0.00005 | $0.00111 |
Grade A, and why
Privilege and Confidentiality Check 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.

Privilege and Confidentiality Check
Purpose
Review draft legal work product for privilege and confidentiality risk. The skill identifies unnecessary disclosure of confidential client information, risky inclusion of privileged communications, missing privilege/work-product labels, anonymization needs, sensitive identifiers, and the need for a safer external-facing version.
This skill does not decide privilege law. It flags issues for attorney judgment.
Use When
- A draft may be sent outside the legal team, to a client, opposing party, regulator, court, vendor, or business stakeholder.
- A draft contains client names, employee names, addresses, account numbers, emails, sensitive facts, privileged communications, or attorney mental impressions.
- A matter workspace or output needs privilege/work-product labeling reviewed.
- The user asks for a redacted, anonymized, or external-facing version.
Required Inputs
- The draft to review.
- Intended recipient, distribution plan, and whether the output is internal or external.
- Any matter confidentiality instructions, client restrictions, protective order, NDA, or privilege-designation guidance.
If recipient and distribution plan are missing, flag that as a gate before external use.
Do Not Use When
- The task is to decide as a matter of law whether privilege applies.
- The user wants to disclose confidential information without attorney authorization.
- The draft is a reusable template or example containing real client information; stop and remove the real information.
Legal Safety Rules
- Produce draft legal work product for attorney review. This is not legal advice.
- Follow
core/confidentiality-and-privilege.md. - Follow
core/source-and-citation-discipline.md; do not invent legal authority, citations, quotations, facts, or deadlines. - Do not decide privilege, waiver, common-interest, work-product, or confidentiality obligations. Flag them for attorney review.
- Do not include unnecessary sensitive details in the check report.
- Do not create reusable examples with real client or matter facts.
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.
