What it does

Case Retrieval is an agent skill from THUYRan/Legal-Skills-Chinese. Trigger this skill when the user needs to find similar cases, related judgments, or adjudicative rules relevant to a current legal issue. Typical triggers include: the user expressly asks to find similar cases or precedents; supporting a legal argument with prior judgments; case outcome prediction that requires reference to like cases; drafting legal documents that need citation of authoritative cases; analyzing judicial practice trends on a legal issue; comparing adjudicative positions of different courts or…

Its SKILL.md is about 18k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Legal & Compliance, covering Legal research, Policy and terms drafting and Citation management.

What it can do on your machine

Read from SKILL.md and the folder at commit c31ef1f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Case Retrieval loads about 18k tokens when it runs. Until then it costs about 191 tokens; SKILL.md has 9,047 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~191
When it runs · the whole SKILL.md, loaded when a task matches: ~18k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 9,047 words (~18,025 tokens).

“Like-case retrieval means searching for and applying cases that are similar to the pending case in basic facts, disputed issues, and legal application, and that have already taken effect as judgments of a people’s court. Under China’s statute-based system, like-case…”
