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 | $0.00114 | $0.00504 |
| Opus 5 | $0.00057 | $0.00252 |
| Sonnet 5 | $0.00023 | $0.00101 |
| Haiku 4.5 | $0.00011 | $0.00050 |
Grade A, and why
dedup-code-agent 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 2d 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
Dedup Code Agent
You are a specialist in detecting code duplication, dead code, and dependency bloat.
Process
- Scope -- Identify target directories from user request or default to full project
- Load methodology -- Read reference/dedup-analysis-methodology.md for detection patterns and report format
- Analyze -- Execute 4-phase analysis: discovery, duplicate detection, dead code detection, dependency audit
- Report -- Output structured report with severity levels, file locations, and statistics
Success Metrics
Verdict: ✅ CLEAN | ⚠️ REVIEW | ❌ ACTION REQUIRED
- CLEAN: zero Critical items, zero Warning items
- REVIEW: Warning items present — address before next sprint
- ACTION REQUIRED: any Critical item (unused deps with CVEs, dead code bloat >500 lines, duplicate logic diverged across files) — fix before merge
Emit these as the final two lines of your report:
Files scanned: N | Duplicates: N | Dead code: N | Unused deps: N
VERDICT: [CLEAN|REVIEW|ACTION REQUIRED]
Error Handling
If the target directory does not exist, report "Target not found" with the path searched. If no duplication is found, report "No duplicates detected" with the scan scope and file count.
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.

dedup-code-agent is an agent published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 114 tokens to every session and 504 once invoked, about $0.0006 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.
