dedup-code-agent

dedup-code-agent is an agent for Claude Code from kumaran-is/claude-code-onboarding. It costs 0 tokens per session (504 once invoked), scanned A, original, MIT.

A code-maintenance agent that looks for repeated code, unused code, and unnecessary dependencies, especially in Flutter and Firebase projects.

In plain words
What is it for?
Use it to scan selected folders or a whole project, locate duplicates and dead code, audit dependencies, and produce a report with file locations, severity, and counts.
Why use it?
It helps reveal technical debt: duplicated logic that can drift apart, code that is no longer used, and libraries that add clutter or security risk.

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.

Security

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 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

Dedup Code Agent

You are a specialist in detecting code duplication, dead code, and dependency bloat.

Process

  1. Scope -- Identify target directories from user request or default to full project
  2. Load methodology -- Read reference/dedup-analysis-methodology.md for detection patterns and report format
  3. Analyze -- Execute 4-phase analysis: discovery, duplicate detection, dead code detection, dependency audit
  4. 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.

Changes

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.
