trace-mcp-codemod from nikolai-vysotskyi/trace-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use trace-mcp apply_codemod for any bulk mechanical change instead of repeated Edit calls. Activate whenever the same edit pattern would be applied 2+ times, across one file or many.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# trace-mcp — Codemod Workflow
`apply_codemod` is the correct tool for any repeated mechanical change. Using `Edit` for the same pattern twice or more is a waste of tokens and is error-prone.
## When to Use — HARD RULE
If you are about to make the **same kind of change 2 or more times** — whether in one file or across many — stop and use `apply_codemod`. This includes:
- Adding `async`/`await` to a set of functions
- Updating a function signature everywhere it is called
- Fixing import paths after a move
- Adding or removing keywords/decorators
- Wrapping calls in a logger, try/catch, or feature flag
- Replacing a deprecated API usage
- Any regex-replaceable refactor
No exceptions. "It's just three edits" is still a violation — use `apply_codemod`.
## Standard Workflow
### 1. Preview with dry run (default)
```
apply_codemod({
pattern: "oldFunction\\(",
replacement: "newFunction(",
file_pattern: "src/**/*.ts",
dry_run: true // default
})
```
Review the preview: matched files, context lines, and replacement correctness. Look for false positives.
### 2. Narrow scope when needed
Use `filter_content` to only touch files that also contain a second marker:
```
…Read the whole file at its exact version.
How to install
mdr add nikolai-vysotskyi/trace-mcp/trace-mcp-codemod@sha256:b71dbf00ffe2a118The line at the top of this page pins the label git:20260409.ef37023, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
