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 | $0.00093 | $0.09279 |
| Opus 5 | $0.00046 | $0.04640 |
| Sonnet 5 | $0.00019 | $0.01856 |
| Haiku 4.5 | $0.00009 | $0.00928 |
Grade A, and why
claim-chart 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 7d 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 — 477 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/claim-chart
- Load
~/.claude/plugins/config/uk-legal-plugins/litigation-legal-uk/CLAUDE.md→ role, work-product header, decision posture, document storage. - If matter workspaces enabled, confirm or select the active matter; load
matter.md(side, jurisdiction, phase, theory, pleadings). - Follow the workflow and reference below.
- Mode selection:
--patent→ patent claim chart. Require patent number and at least one asserted claim. Sub-modes:--infringement,--invalidity,--review.--civil→ civil element chart. Require the cause of action (or defence) and the side.- No flag → ask the user which.
- For civil mode: consult
references/element-templates.mdin the skill directory for the baseline element list. Confirm the controlling pattern instruction or statute with the user before mapping. - For patent mode: parse asserted claims into elements, flag disputed terms for construction, apply any claim construction ruling.
- Map elements against the target (accused product / prior art / evidence corpus / chart under review). Every cell pin-cited. Apply the apostrophe-prefix neutralisation before writing any cell value starting with
=,+,-,@, tab, or CR. - Produce the gap list (civil) or needs-evidence list (patent) — the priority output.
- Write markdown, CSV (values +
_sourcescompanion), and Excel or Sheets per user preference. Work-product header on every output. - Write to the matter's
claim-charts/folder if a matter is active; otherwise the practice-levelclaim-charts/folder. Append a one-line entry tohistory.mdif a matter is active. - Return a summary readout: claim(s), target(s), jurisdiction, phase, element counts by state, the gap list, file paths, and the reminder that every cell is a lead.
Claim Chart
Disclosed-document use restrictions
Before working with a set of litigation documents, ask: "Were any of these documents obtained through disclosure in legal proceedings?" If yes:
- England & Wales (CPR 31.22): Documents obtained through disclosure are subject to the implied undertaking — you may only use them for the purpose of the proceedings in which they were disclosed, unless the court grants permission, the disclosing party consents, or the document has been read in open court. Using them for a different matter, a different claim, or a commercial purpose without permission is a contempt.
- Scotland: Equivalent undertaking principles apply under the Rules of the Court of Session and the Sheriff Court Rules. Confirm with Scottish solicitors.
- Other jurisdictions: Similar restrictions commonly apply. Check the local rule.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claim-chart is a skill published in the GitHub repository uk-agents/uk-legal-plugins (9 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 93 tokens to every session and 9,279 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
