ashlr__edit

Diff-format edit. Sends only old_string + new_string, never the full file contents.

Server: ashlr-efficiency — servers/efficiency-server.ts

Replaces Claude Code's built-in Edit tool. The key difference: only the search string and replacement string are transmitted — the server reads the file locally, applies the edit, and confirms. This avoids sending the full file body back and forth.

Input schema

Field	Type	Required	Description
`path`	`string`	yes	Absolute or repo-relative file path
`search`	`string`	yes	Exact string to find (must be unique in the file)
`replace`	`string`	yes	Replacement string
`strict`	`boolean`	no	Fail if `search` matches more than once (default: true)

Output format

Returns a compact diff summary:

[ashlr__edit] servers/efficiency-server.ts  ·  1 of 1 hunks applied
  - removed (42 tok):  const PRICING = { ... }
  + added   (38 tok):  const PRICING = { ... }

Example

Use ashlr__edit to change the SNIP_THRESHOLD from 2048 to 4096 in servers/efficiency-server.ts

Savings baseline

Typical savings: −60 to −90 % vs a Read + full-file Write round-trip. Savings scale with file size — a 10 KB file with a 20-character change sends ~40 characters instead of 10,000.

Strict mode

By default, strict: true — if search matches more than once, the edit is rejected and an error is returned. Set strict: false to apply the replacement to all occurrences (equivalent to replace_all).

ashlr__multi_edit — batch edits across multiple files atomically
ashlr__read — read first to find the exact string to search for
