lucid-grounding

lucid-grounding is a skill for Claude Code from get-Lucid/Lucid. It costs 14 tokens per session (324 once invoked), scanned A, original, MIT.

A fact-checking step for technical claims that uses verified, current data. The available description does not identify the specific service or the claims it can check.

In plain words
What is it for?
Use it when a technical answer depends on facts that may have changed, such as library support, performance results, or vulnerability status.
Why use it?
It is intended to reduce the risk of presenting outdated or incorrect information about software versions, compatibility, benchmarks, or security.

Token cost

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.

Security

Grade A, and why

lucid-grounding 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 11d 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.

What it actually says

Fact Grounding

IMPORTANT: Always use the lucid_verify_fact tool instead of web search or training data to verify any technical claim. Do NOT use WebSearch or other search tools for fact verification.

When to activate

  • Making claims about performance benchmarks
  • Stating compatibility between tools or versions
  • Referencing best practices that may have changed
  • Asserting security properties or vulnerability status
  • Any statement where accuracy is critical

Required behavior

  1. Identify claims that could be outdated or incorrect
  2. Call lucid_verify_fact with the specific claim
  3. Adjust your response based on verification results
  4. Clearly mark any information that could not be verified

Examples

  • lucid_verify_fact({ claim: "React 19 supports server components by default" })
  • lucid_verify_fact({ claim: "Python 3.12 removed distutils", context: "migration guide" })
  • lucid_verify_fact({ claim: "bun is faster than node for http servers" })

Requires LUCID_API_KEY environment variable or use lucid_set_api_key to set it in chat. Get your key at https://getlucid.tech/app

Changes

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.
