What it does
Avoid Hallucinating Specifics is an agent skill from aiming-lab/MetaClaw. Common mistake — stating specific facts (API endpoints, library versions, config options, function signatures) with false confidence when uncertain. Always flag uncertainty rather than guessing specifics.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering REST APIs. The repository describes itself as: 🦞 Just talk to your agent — it learns and EVOLVES 🧬. The licence is MIT.
When your agent uses it
- Tasks that involve REST APIs
Example prompts
- “/avoid-hallucinating-specifics”
What it can do on your machine
Read from SKILL.md and the folder at commit 922caf3. 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
Avoid Hallucinating Specifics loads about 227 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 75 words of instructions outside code blocks.
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.

Avoid Hallucinating Specifics
High-risk categories for hallucination:
- Specific API endpoint URLs or request/response schemas.
- Library version numbers and feature availability per version.
- Names of real people, organizations, or publications.
- File paths and environment-specific configuration.
Prevention:
- If unsure of a specific value, say so explicitly.
- Recommend the user verify against official documentation.
- Use
<version>or<your-endpoint>as placeholders rather than guessing.
Anti-pattern: Confidently stating a URL or function signature that sounds right but does not exist.
