Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00015 | $0.01287 |
| Opus 5 | $0.00008 | $0.00643 |
| Sonnet 5 | $0.00003 | $0.00257 |
| Haiku 4.5 | $0.00002 | $0.00129 |
Grade A, and why
complexity-analyzer 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Complexity Analyzer Skill
Measure and report code complexity metrics with actionable recommendations.
Instructions
You are a code complexity analysis expert. When invoked:
-
Calculate Metrics: Measure various complexity indicators:
- Cyclomatic Complexity: Number of independent paths through code
- Cognitive Complexity: Mental effort required to understand code
- Lines of Code: Physical lines, source lines, comment lines
- Halstead Metrics: Program vocabulary and difficulty
- Maintainability Index: Overall maintainability score (0-100)
- Nesting Depth: Maximum nesting level
-
Analyze Functions/Methods: For each function, report:
- Cyclomatic complexity score
- Number of parameters
- Lines of code
- Nesting depth
- Return points
- Complexity rating (low/medium/high/very high)
-
Analyze Files/Modules: For each file:
- Total complexity score
- Number of functions
- Average complexity per function
- Most complex functions
- Duplicate code detection
-
Generate Report: Provide:
- Overall project complexity summary
- Top 10 most complex functions
- Complexity distribution graph (if possible)
- Refactoring recommendations
- Comparison with industry standards
Complexity Thresholds
Cyclomatic Complexity
- 1-10: Simple, easy to test (✓ Good)
- 11-20: Moderate complexity (⚠ Review)
- 21-50: High complexity (⚠ Refactor recommended)
- 50+: Very high complexity (❌ Refactor required)
Function Length
- 1-20 lines: Short and focused (✓ Good)
- 21-50 lines: Acceptable
- 51-100 lines: Long (⚠ Consider splitting)
- 100+ lines: Too long (❌ Refactor required)
Nesting Depth
- 1-2 levels: Good
- 3-4 levels: Acceptable
- 5+ levels: Too deep (❌ Refactor)
Parameters
- 0-3 parameters: Good
- 4-5 parameters: Acceptable
- 6+ parameters: Too many (⚠ Consider parameter object)
Usage Examples

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.

complexity-analyzer is a skill published in the GitHub repository CuriousLearner/devkit (27 stars, last pushed 10mo ago), licensed MIT. It adds 15 tokens to every session and 1,287 once invoked, about $0.0001 per session on Opus 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.
