uncertainty-verification

uncertainty-verification is a skill for Claude Code, Codex from kasuken/github-copilot-superpowers. It costs 50 tokens per session (983 once invoked), scanned A, original, MIT.

A fact-checking rule for exact technical details that may vary by software version, environment, or specification.

In plain words
What is it for?
Use it when giving copy-paste commands, configuration instructions, API details, standards-related answers, or other precise technical guidance.
Why use it?
It prevents guesses about commands, flags, configuration keys, file paths, APIs, standards, and version-specific behavior. Such details must be checked against official documentation and cited.

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

uncertainty-verification 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 4d 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.

Uncertainty Verification

Overview

This skill forces verification before stating any specific technical detail that could vary by version, environment, or specification.

Use when...

  • The request asks for exact command syntax, flags, or configuration keys
  • The answer depends on version-specific behavior, deprecations, or recent changes
  • The request involves standards/specs (RFCs, protocol behavior, i18n/timezone/locale rules)
  • The user asks for exact file paths, naming conventions, or directory structures
  • The answer requires library-specific APIs (class names, method signatures, constants)
  • Any part of the response would otherwise be based on “typical patterns” or memory

Symptoms / keywords

Use this skill when the prompt contains or implies keywords like:

  • “exact”, “precise”, “verbatim”, “copy/paste”, “flags”, “CLI”, “config key”, “endpoint”, “params”
  • “deprecated”, “since vX”, “in 2025”, “changed in”, “breaking change”, “migration”
  • “RFC”, “spec”, “standard”, “format”, “timezone”, “locale”, “i18n”, “OAuth”, “HTTP”, “GraphQL”
  • “directory structure”, “file path”, “naming convention”, “default location”
  • Specific error codes/messages that must be accurate

Technical Details Requiring Verification

Don't provide these specific details without checking official documentation:

  • ❌ Exact file paths, directory structures, or naming conventions
  • ❌ Specific API endpoints, parameter names, or response formats
  • ❌ Exact command syntax, flags, or configuration keys
  • ❌ Version-specific features or deprecations
  • ❌ Specific error codes or messages
  • ❌ Hostname patterns, URL formats, or connection string syntax
  • ❌ Library-specific class names, method signatures, or constants

Required response pattern when uncertain:

"I need to verify this with official documentation. Let me check..."
→ Dispatch a research subagent to execute Context7 or Web fetch and return a Context Package with citations
→ Cite the source explicitly

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.
