Hashline edits (LINE#ID)

oh-my-grok caches per-line hashes after each workspace Read. Use those tags in StrReplace old_string when you need precise, conflict-safe edits.

Format

Each line from Read is tagged as:

{line}#{hash}|{content}

• line: 1-based line number
• hash: two letters from ZPMQVRWSNKTXJBYH (content fingerprint)
• Copy tags exactly — never guess hashes

Example: 11#XJ| console.log("hi"); → anchor 11#XJ (omit |content in old_string unless you intentionally include it; the hook strips |… when matching).

Workflow

1. Read the target file (hooks refresh the hashline cache).
2. Copy the smallest set of LINE#ID anchors you need into old_string.
3. StrReplace once per logical change batch; re-read before a second edit on the same file.
4. If PreToolUse denies with “stale LINE#ID”, Read again and use the updated tags from the error or fresh read.

Rules

• Anchors in old_string must match the last Read cache for that path.
• Whitespace in old_string must still match file content; hashes only guard line identity.
• SKILL.md reads are not cached — use normal edits for skills.
• Disable validation: OMG_HASHLINE=0.

Configuration
