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 | $0.00118 | $0.01920 |
| Opus 5 | $0.00059 | $0.00960 |
| Sonnet 5 | $0.00024 | $0.00384 |
| Haiku 4.5 | $0.00012 | $0.00192 |
Grade A, and why
legal-matter-tracker 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 12d 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Legal Matter Tracker
This skill scans a local Cowork workspace for files related to a specified client or legal matter, extracts dated events and key facts, and assembles a structured chronological timeline report — entirely from local files, with no external integrations required.
Input: Client or case name (required). Optional: folder path to narrow scan scope.
Output: Structured markdown timeline report (inline). Optionally saved to output/matter-timeline-[client]-YYYY-MM-DD.md on request.
Language Detection
Detect the user's language from their message:
- If Russian (or contains Cyrillic): respond in Russian
- If English (or other Latin-script language): respond in English
- If ambiguous: default to English
Instructions
Step 1: Parse Input
-
Extract the client or case name from the user's message.
- Accepted forms:
"case timeline for Acme Corp","track Smith matter","хронология по делу Иванов","что было по клиенту Ромашка". - The name may be a company, person, project code, or case identifier.
- Accepted forms:
-
If no name is provided, return:
- EN: "Please provide a client or case name. Example: 'Case timeline for Acme Corp'"
- RU: "Укажите имя клиента или название дела. Пример: «хронология по делу Ромашка»" Stop — do not generate output.
-
If the user provided a folder path to narrow the scan scope, note it. Otherwise scan the full workspace.
Step 2: Scan Workspace
-
Search for files that match the client/case name using these criteria:
- Filename match: filename contains any word from the name (case-insensitive).
- Content match: file contains the name in a heading (
#,##,**Name**) or first 10 lines. - Accepted file types:
.md,.txt. - Search folders: workspace root +
notes/,clients/,cases/,input/,output/,context/.
-
If a folder path was provided: scan only that folder (recursive).
-
Count total files scanned and matching files found.
-
If no matching files found, return:
- EN: "No files found matching '[name]'. Try a broader term or check that the relevant files are in your workspace."
- RU: "Файлов по запросу «[name]» не найдено. Попробуйте более широкий запрос или проверьте, что нужные файлы есть в воркспейсе." Stop — do not generate output.
What ships with it
4 files 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.

legal-matter-tracker is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 118 tokens to every session and 1,920 once invoked, about $0.0006 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 2026-08-30.
