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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00293 |
| Opus 5 | $0.00011 | $0.00147 |
| Sonnet 5 | $0.00004 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
review-duplicates 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 11d 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
When subagents are enabled in Codex, prefer delegating this workflow to the code-refactor-agent custom agent.
Detect duplicate code in the ccswarm codebase using similarity-rs.
similarity-rs crates/ --threshold 0.80
For Rust code, also consult cargo coupling so duplicate cleanup is prioritized
by architectural impact, not only by textual similarity.
cargo coupling . --summary --exclude-tests
cargo coupling . --hotspots=12 --exclude-tests
If a duplicate cluster is located in a coupling hotspot, high-risk boundary, or cycle-related module, raise its refactoring priority accordingly.
Classify results by priority:
| Priority | Condition | Action |
|---|---|---|
| High | 95%+ similarity, 10+ lines | Extract to common function |
| Medium | 90-95% similarity, 5+ lines | Consider trait or macro |
| Low | 85-90% similarity | Evaluate structural similarity |
| Skip | Test code, config structs | Allow intentional duplication |
Output a JSON report with high_priority, medium_priority, low_priority, and ignored sections.
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.

review-duplicates is a skill published in the GitHub repository nwiizo/ccswarm (151 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 293 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.
