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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00013 | $0.00290 |
| Opus 5.5 | $0.00005 | $0.00116 |
| Sonnet 5.5 | $0.00003 | $0.00058 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade A, and why
complexity-report 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.
What it actually says
Complexity Report
Directory: $1 (or src/ if not specified)
- Find complex functions manually (no external tool needed):
# Functions longer than 50 lines
grep -n "^function \|^ [a-z].*(.*) {" ${1:-src}/**/*.ts 2>/dev/null | head -30
Read the top 10 largest files and functions.
-
For each file over 300 lines or function over 40 lines:
- Count the number of if/else/switch/for/while/try blocks (= cyclomatic complexity)
- Note the nesting depth
- Identify the "complexity source"
-
Rank by complexity and report:
Top 5 Complexity Hotspots:
src/auth/middleware.ts:handleRequest() CC: 18 Lines: 87
src/api/router.ts:routeRequest() CC: 14 Lines: 120
...
Refactoring recommendations:
1. handleRequest() - extract 3 auth validation blocks into separate functions
2. ...
- Offer to refactor the top offender.
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-report is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (11 stars, last pushed 6mo ago), licensed MIT. It adds 13 tokens to every session and 290 once invoked, about $0.0001 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 2026-08-31.
