Updated read.ts to continue reading with offset on truncation.
EditAdded trailing periods for consistency.
EditConfirmed description instructs model to continue reading.
VerifyCommitted changes to read.ts only.
Build
@packages/coding-agent/src/core/tools/read.ts if the file is truncated, we should tell the agent to continue reading with offset if the user instructed it to read the full file
Summary:
Tests not run (not requested).
const shouldSuggestContinuation = limit === undefined;
how does this make sense? don't we just need to check if we truncated, and then suggest continuation?
also, when the first line exceeds the limit, we still need to tell the model to use sed + bash truncation.firstLineExceedsLimit
Use offset=${nextOffset} to continue.` this is a piss poor note. the model should only continue if it ws intstructed to do so by the user. as in
read @packages/tui/src/fuzzy.ts etc.
also, maybe we should modify the description to be explicit, that in case of the model needing to read a file in full which gets truncated, it should use offset to continue reading the rest of the file
wtf are you doing? i did not ask you to add a new parameter to the read tool.
i also told you that this won't fly, offset is line based, not byte based
f (truncation.firstLineExceedsLimit) {
// First line at offset exceeds 30KB - tell model to use bash
const firstLineSize = formatSize(Buffer.byteLength(allLines[startLine], "utf-8"));
const nextOffset = startLineDisplay + 1;
const continuationNote = shouldSuggestContinuation
? If you need the full file, continue with offset=${nextOffset} to read the next line.
: "";
outputText = [Line ${startLineDisplay} is ${firstLineSize}, exceeds ${formatSize(DEFAULT_MAX_BYTES)} limit. Use bash: sed -n '${startLineDisplay}p' ${path} | head -c ${DEFAULT_MAX_BYTES}.${continuationNote}];
details = { truncation };
}
so we need to keep the old stuff here
You're right. The firstLineExceedsLimit case needs the bash/sed instruction since offset won't help there (it's line-based). Only the other truncation cases should get the continuation hint.
Let me check the current state and fix it properly:
The file has broken code (references to shouldSuggestContinuation which doesn't exist, extra tab). Let me fix the entire truncation block properly:
Let me revert the broken changes and apply cleanly:
Now let me make the correct changes:
Done. Changes:
Description: Added "If the user asks to read the full file and output is truncated, continue with offset to read the rest."
Truncation messages (3 places): Changed from "Use offset=X to continue" to "If the user asked for the full file, use offset=X to continue."
firstLineExceedsLimit unchanged: Left as-is since offset is line-based and won't help when a single line exceeds the byte limit.
Use offset/limit for large files. If the user asks to read the full file and output is truncated, continue with offset to read the rest.`,
this is poor, no? what instructions would like to read here? concise
You're right. Something like:
Use offset/limit for large files. When the user asks to read a full file, continue with offset until complete.it may not be just the user who needs the full file no? we should word this in such a way that it's obvious for the model that if it needs the full file (for its own undersatnding or because the user asked to read the full file) it can read the full file in chunks using offset
Right. Something like:
When you need the full file, continue with offset until complete.And update the truncation messages to match:
Clean. The description now tells the model "When you need the full file, continue with offset until complete." The truncation messages just provide the offset value. Only change otherwise is adding trailing periods for consistency.
ok, commit the changes to read.ts, nothing else, do not modify or reset anything else in the working tree
Done. Committed abb6580c with only the read.ts changes.
exit
