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.

Fable 5.1 $0.00030 $0.00670
Opus 5.5 $0.00012 $0.00268

Security

Grade A, and why

code-review 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 2mo 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.

Agent Integration

This Skill calls the code-analyzer Agent for in-depth code analysis.

Agent Role
code-analyzer Code quality, security, performance analysis

Usage Examples

# Review specific file
/code-review src/lib/auth.ts

# Review entire directory
/code-review src/features/user/

# PR review
/code-review pr 42

# Review current changes
/code-review staged

Confidence-Based Filtering

code-analyzer Agent uses confidence-based filtering:

Confidence Display Description
High (90%+) Always shown Definite issues
Medium (70-89%) Selectively shown Possible issues
Low (<70%) Hidden Uncertain suggestions

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.
