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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.00983 |
| Opus 5.5 | $0.00020 | $0.00393 |
| Sonnet 5.5 | $0.00010 | $0.00197 |
| Haiku 4.5 | $0.00005 | $0.00098 |
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 1mo 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
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.

uncertainty-verification is a skill published in the GitHub repository kasuken/github-copilot-superpowers (17 stars, last pushed 8mo ago), licensed MIT. It adds 50 tokens to every session and 983 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
