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 | $0.00109 | $0.07365 |
| Opus 5.5 | $0.00044 | $0.02946 |
| Sonnet 5.5 | $0.00022 | $0.01473 |
| Haiku 4.5 | $0.00011 | $0.00737 |
Grade B, and why
skills-qa scanned grade B with 2 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 1mo 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
1. **Override / ignore instructions** — "ignore previous instructions", Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
8. **Shell / code execution** — any instruction to run shell commands, curl Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 700 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/skills-qa
Inputs accepted
- File path to a skill directory (preferred — enables full dependency mapping)
- File path to a SKILL.md only
- SKILL.md content pasted directly into the conversation
Context to load
~/.claude/plugins/config/claude-for-legal/legal-builder-hub/CLAUDE.md→ practice profile and installed skills list (provides context for evaluating whether the skill fits the user's team and workflow, and whether it duplicates something already installed)
Notes
This QA check runs automatically as part of /legal-builder-hub:skill-installer. You can also run it directly on any skill before deciding whether to install, or on a first-party skill before deploying to your team.
Run it deliberately — before incorporating any community skill you did not build,
or before deploying a first-party skill to your team.
If the user runs /legal-builder-hub:skill-installer and then asks "should I trust
this?" or "is this well-designed?", route to this skill rather than answering
inline.
Purpose
Anyone can build a skill. This one checks whether it was built well before it touches your workflows.
Evaluates any skill against the Legal Skill Design Framework: thirteen design parameters (the first nine are substantive design; the tenth is Trust Surface — the skill's execution permissions and injection risk; the eleventh is Freshness — whether bundled reference content is current; the twelfth is Schema — whether the SKILL.md has the structure a well-built skill needs; the thirteenth is Conflicts — whether the skill overlaps or conflicts with skills already installed), three legal-specific failure modes, a dependency map, and a clear verdict. Works for community skills from registries and first-party skills your team is building or deploying.
Inputs accepted
- A path to a full skill directory
- A path to a SKILL.md file
- SKILL.md content pasted directly into the conversation
If only SKILL.md is provided, ask once: "Do you have the associated commands, agents, or hooks for this skill? The full picture changes what I can assess — particularly on dependencies and automatic triggers." Proceed either way; flag in the output if dependency mapping is incomplete.
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.

skills-qa is a skill published in the GitHub repository anthropics/claude-for-legal (9,810 stars, last pushed 4d ago), licensed Apache-2.0. It adds 109 tokens to every session and 7,365 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-23.
