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 | $0.00079 | $0.06883 |
| Opus 5.5 | $0.00032 | $0.02753 |
| Sonnet 5 | $0.00016 | $0.01377 |
| Haiku 4.5 | $0.00008 | $0.00688 |
Grade A, and why
infringement-triage 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 6d 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 — 629 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/infringement-triage
This is a triage, not a finding of infringement or non-infringement. Infringement analysis is fact-intensive and legally complex. Acting on a triage — sending a cease-and-desist, refusing to stop, filing suit, or deciding not to — without attorney review is how companies end up on the wrong side of fee awards, Rule 11 sanctions, declaratory-judgment actions, and (for patents) treble damages.
Instructions
- Read
~/.claude/plugins/config/claude-for-legal/ip-legal/CLAUDE.md. If it contains[PLACEHOLDER], stop and direct to/ip-legal:cold-start-interview. - Follow the workflow below.
- Ask which right is at issue — trademark / copyright / patent / trade secret / mixed. If mixed, run each separately; do not blend.
- Run common intake (party posture — senior or accused, jurisdiction, timing, exhibits).
- Walk the mode-specific factors:
- Trademark — circuit's confusion test + dilution (if famous) + false advertising (if a comparative claim).
- Copyright — ownership + registration + access + substantial similarity + fair use + DMCA safe harbor (if applicable).
- Patent — claim-chart first pass (route to
fto-triageoutput structure); literal + DOE; indirect + divided; invalidity defenses to consider. - Trade secret — secrecy + reasonable measures + misappropriation; preemption + reverse-engineering flags.
- Produce a flag list with direction — what cuts toward the senior party, what cuts toward the accused, what's mixed. Never conclude.
- Write the triage memo to the matter folder or practice outputs folder. Apply the work-product header per role.
- End with recommended next steps, the non-lawyer gate if the role is
non-lawyer, and — if the practice posture supports assertion — an offer to
draft the C&D via
/ip-legal:cease-desistor the takedown via/ip-legal:takedown. Do not draft automatically.
This skill never concludes. If uncertain, flag — the attorney decides.
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.

infringement-triage is a skill published in the GitHub repository anthropics/claude-for-legal (9,544 stars, last pushed 4d ago), licensed Apache-2.0. It adds 79 tokens to every session and 6,883 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-23.
