intent-based-dedup

intent-based-dedup is a skill for Claude Code, Codex from amadeus-dlc/amadeus. It costs 67 tokens per session (303 once invoked), scanned A, original, Apache-2.0.

A code-review guide for deciding when similar code should be combined based on its purpose and likely future changes, not just matching text.

In plain words
What is it for?
Use it when reviewing duplicate code, making DRY decisions, merging functions, or choosing names and risks for a shared helper.
Why use it?
It helps avoid abstractions that make unrelated code change together, while still identifying genuinely shared behavior.

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

intent-based-dedup 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 6d 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

Intent-Based Deduplication

Deduplicate by intent, not by appearance. Similar text with different reasons to change should stay separate.

Workflow

  1. Identify the duplicated code and every caller.

  2. Name the business or technical intent of each copy.

  3. Compare future change reasons, owners, invariants, and release cadence.

  4. Deduplicate only when the shared abstraction can be named honestly and will change for one reason.

  5. If intent differs, keep duplication or extract smaller mechanical helpers that do not pretend to be domain concepts.

Decision Matrix

  • Same text, same intent: merge.

  • Same text, different intent: keep separate.

  • Different text, same intent: consider unifying.

  • Different text, different intent: do not merge.

Detailed Reference

For non-trivial implementation, review, or refactoring work, read references/details.md before giving final guidance. It contains the detailed rules, examples, smells, and migration notes that do not belong in the short invocation body.

Output

Return the intent comparison, decision, proposed abstraction name if any, and risks of coupling.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
