Claude for Legal is a collection of AI agents, skills, and data connectors for legal work such as commercial, privacy, employment, litigation, regulatory, and intellectual-property matters. Lawyers and legal teams use it through Claude Cowork, Claude Code, or the Claude Managed Agents API, with attorney review required for every output. The catalogue entries are its workflow plugins, skills, agents, and connectors.
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.

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 | $0.00068 | $0.03237 |
| Opus 5.5 | $0.00027 | $0.01295 |
| Sonnet 5.5 | $0.00014 | $0.00647 |
| Haiku 4.5 | $0.00007 | $0.00324 |
Grade A, and why
marketing-claims-review 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 23d 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.

/marketing-claims-review
- Load
~/.claude/plugins/config/claude-for-legal/product-legal/CLAUDE.md→ Marketing claims standards. - Apply the claim taxonomy and review workflow below.
- Extract every claim. Classify: puffery / factual / comparative / implied / absolute.
- For each non-puffery claim: substantiation check, suggested fix.
- Output: claim-by-claim with calls, suggested revision if short enough.

Matter context
Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /product-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/product-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
Purpose
Marketing wants to say the product is the best. Legal needs it to be true, or at least not provably false. This skill finds the claims that will get a demand letter from a competitor or an inquiry from a regulator, and suggests how to keep the energy while fixing the exposure.
Load standards
Read ~/.claude/plugins/config/claude-for-legal/product-legal/CLAUDE.md → ## Marketing claims:
- Comparative claims policy (allowed with substantiation / discouraged / never)
- Substantiation standard (what's required before a claim ships)
- Common rejected claims (learn from history)
Research the applicable standards before clearing copy
Research the currently operative advertising and substantiation standards for the applicable jurisdictions and media (for example, FTC, NAD, state UDAP regimes, sector regulators for healthcare / financial / children's products, and platform-specific policies). Identify what substantiation the specific claim requires — who measured it, when, sample size, apples-to-apples basis — not just whether some substantiation exists on file. Flag implied claims and comparative claims for heightened scrutiny. Verify currency: endorsement and review guides have been updated recently and continue to evolve. Cite primary sources with pinpoint references. If you cannot verify the current standard, flag for attorney verification — do not state a rule you haven't confirmed.
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.
