When get_session_errors is called with the supported limit: 100 and the failures contain long operations or errors, the rendered digest can exceed 40,000 characters. This cap then cuts the JSON partway through the failure array, but JudgeErrorDigest.Render has already emitted next_offset = offset + page.Count, so following that offset skips every row removed by the character cap. Limit the page to rows that actually fit, or calculate next_offset from the last delivered row.

Fixed in 2576c57. The digest is assembled from pre-serialized fragments against the cap, so a page is always one complete document and next_offset follows the last row it holds.

When /errors entries omit tool_input, as the existing ErrorEntry contract and server-backed fixture currently do, Operation returns an empty string. Consequently, any two failures from the same tool are reported as one repeated operation with operation: "", even if they came from unrelated commands; the tool description then presents this as direct evidence of repeated failed attempts. Unknown operations should not be grouped together.
Useful? React with 👍 / 👎.

Fixed in 2576c57. A failure whose input names nothing it acted on has no grouping key and never joins a repeated_operations group.

For commands or paths longer than 200 characters, two distinct operations with the same prefix are reduced to the same string here and subsequently grouped as repeated attempts. This can happen with long test or build commands whose distinguishing filter or target is near the end, producing false evidence for the judge. Preserve the normalized full value as the grouping key and clip only the displayed operation field.
Useful? React with 👍 / 👎.

Fixed in 2576c57. Groups key on the full normalized operation; only the displayed operation is clipped.

Review comments at @src/Capacitor.Cli/Commands/JudgeErrorDigest.cs:
- Line 102: Update the operation normalization used for grouping so it retains
the full result of Collapse(s) as the grouping key; apply Clip with
OperationChars only when producing the displayed operation value. Ensure
commands that differ after the clipping limit remain separate groups.
Review comments at @src/Capacitor.Cli/Commands/JudgeSearchExcerpts.cs:
- Around line 40-41: Update the term normalization in `JudgeSearchExcerpts` to
remove a trailing FTS5 prefix operator before locating matches, so a query such
as `needle*` matches `needle` in the snippet. Add a test covering a prefix-query
hit and verifying the excerpt includes the match.
Review comments at @src/Capacitor.Cli/Commands/McpJudgeServer.cs:
- Line 243: Update the `get_session_errors` and `search_session` response
construction before `JudgeResultCap.Cap` so the character budget is applied to
structured rows before serialization, keeping the result valid JSON. Set
`next_offset` from the rows actually returned, and avoid truncating the
serialized response.

What & why
On a long session the legacy-route judge answered
insufficient_evidencebecauseget_session_errorsandsearch_sessionreturned more than Claude Code shows inline. Claude Code saved the results to files, and the judge has no tool that reads files. Everykcap mcp judgeresult is now capped below that limit, with a note on how to narrow the call.get_session_errorsreturns a paged summary that groups failures by repeated operation,search_sessioncuts long snippets to a window around the query term, andget_tool_resultpages a long body byoffset.Where to look
JudgeErrorDigest: the grouping key (tool plus the command, path or pattern acted on) is what the repeated-failures question reads. The tools prompt is unchanged because it is byte-pinned, so the new arguments are described only in the tool schemas. A row'scall_idappears once the server sends it (kurrent-io/kcap-server companion PR).Verification
Unit tests cover grouping, paging, head-and-tail error excerpts, refs across a chain, the cap and the search window. Reverting the grouping threshold or the snippet windowing makes its test fail. A Release AOT publish reports no IL warnings.
