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
- Read the target file (hooks refresh the hashline cache).
- Copy the smallest set of
LINE#ID anchors you need into old_string.
- StrReplace once per logical change batch; re-read before a second edit on the same file.
- 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
| Variable | Default | Effect |

OMG_HASHLINE | 1 | 0 disables cache + PreToolUse guard |
UserPromptSubmit may include <HASHLINE_CACHE> listing recently read files and sample tags.
