codeeraser

A project-level code-duplicate guard and cleanup tool. It detects repeated code when files are changed, records findings, and guides safe deletion of duplicates.

In plain words
What is it for?
Use it to monitor duplicate writes, inspect duplicate-code findings, measure changed lines, and safely delete approved duplicates.
Why use it?
It helps prevent new duplicate code and makes existing repetition easier to review before removing it.

Grade A, and why

codeeraser 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.

What it actually says

{
  "name": "codeeraser",
  "description": "CodeEraser passive guard + erase skill: a winnowing clone index behind a per-project daemon intercepts T1/T2 duplicate writes at PreToolUse, audits net LOC + touched duplicates at Stop, and reports health at SessionStart; the erase skill walks findings to safe, re-gated deletions. Gradual modes observe/warn/ask/deny via ce.toml [guard]; every event feeds .ce/observe.ndjson. The starter resolves both binaries (ce + the ce-core judgment core) by pin (ADR-007): a copy in the plugin data dir or on PATH whose SHA256 matches plugin/bin/manifest.env answers first — the installer leaves one there — then a pinned download from GitHub Releases, then an unverified PATH binary that says so.",

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.
