What it does

Source Locked Verification is an agent skill from lawve-ai/awesome-legal-skills. No Inference / Source-Locked Verification. Forces Claude to answer ONLY from user-provided materials and/or online sources actually accessed — no inference, no assumptions, no gap-filling. Every factual, legal, numerical, or procedural claim must be anchored to a cited source. Use whenever Claude reviews documents, summarises evidence, checks accuracy, drafts submissions, creates timelines, extracts facts, checks citations, analyses rules, prepares legal arguments, compares documents, verifies claims, produces…

Its SKILL.md is about 5.8k 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 and Citation management. The repository describes itself as: A curated list of awesome Agent Skills for automating legal work.

When your agent uses it

  • Claude reviews documents
  • Summarises evidence
  • Checks accuracy
  • Drafts submissions

Example prompts

  • “source-locked”
  • “no inference”
  • “only from the materials”
  • “/source-locked-verification”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Answer
  2. Source Basis
  3. Sources Checked
  4. Points Not Found
  5. Any Limited Inferences (only if requested)

What it can do on your machine

Read from SKILL.md and the folder at commit 045f738. 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.

    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

Source Locked Verification loads about 5.8k tokens when it runs. Until then it costs about 241 tokens; SKILL.md has 3,243 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~241
When it runs · the whole SKILL.md, loaded when a task matches
~5.8k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,243 words (~5,841 tokens).

“This skill exists because Claude's default behaviour is to be helpful — and being helpful often means filling gaps, making reasonable inferences, and providing complete-sounding answers. That default is dangerous when the user needs evidential fidelity. A plausible-sounding date that…”
