fix: widen MOIM allowlist to apply fix_conversation repairs for orphaned tool blocks by wpfleger96 · Pull Request #7684 · aaif-goose/goose

wpfleger96 · 2026-03-06T00:13:23Z

Widen MOIM allowlist so fix_conversation repairs for orphaned tool blocks are applied instead of discarded.

When a session contains orphaned tool_use/tool_result blocks (e.g., from cancellation during tool collection or interrupted streaming), inject_moim calls fix_conversation which correctly detects and removes the orphans — but then checks the resulting issues against an allowlist before deciding whether to use the fixed conversation. "Removed orphaned tool response" and "Removed orphaned tool request" were not in the allowlist, so has_unexpected_issues was true and MOIM discarded the fix, returning the original broken conversation to the provider. This caused persistent Anthropic API 400 errors (tool_use ids were found without tool_result blocks) on every subsequent request in an affected session — a death loop.

MOIM operates on a clone of the conversation each iteration, so it effectively becomes a per-turn safety net: even if the underlying conversation variable retains the orphan, the fixed copy is what reaches the provider.

Widens the has_unexpected_issues allowlist in inject_moim to include all fix_conversation repair types: orphan removal, empty message cleanup, leading/trailing assistant removal, and text content merging
Adds tracing::info! when MOIM applies conversation fixes (previously, successful fixes were silent — only rejected fixes logged a warning)
Adds 2 tests in moim.rs: test_moim_fixes_orphaned_tool_request (core allowlist fix), test_moim_fixes_cancellation_orphan (production scenario with empty pre-allocated user message)
Adds 1 test in context_mgmt/mod.rs: test_compaction_output_with_new_tool_pair_is_valid (regression guard proving compaction output is structurally clean)

…ned tool blocks Production death loop: after tool-heavy responses, orphaned tool_use/tool_result blocks cause persistent Anthropic API 400 errors. fix_conversation correctly detects and repairs these orphans, but MOIM's allowlist only permitted merge operations. Any other fix — including orphan removal — caused MOIM to discard the repair and return the original broken conversation to the provider. Widens the allowlist to also accept orphan removal, empty message cleanup, leading/trailing assistant removal, and text content merging. These are all legitimate repairs that fix_conversation should be allowed to apply regardless of whether MOIM insertion triggered the detection.

CI fails with E0639 because CallToolRequestParams and CallToolResult are #[non_exhaustive] — struct literals are forbidden from outside the crate. Replace with CallToolRequestParams::new() and CallToolResult::success().

Keep assistant-removal issues out of MOIM allowlist

Allowlisting "Removed leading assistant message" and "Removed trailing assistant message" here makes inject_moim accept fix_conversation outputs that delete assistant turns instead of falling back to the original conversation. In compacted sessions, the compaction summary/continuation is stored in assistant message(s) (compact_messages builds and merges them in context_mgmt/mod.rs), so once MOIM is inserted and fix_conversation trims a leading/trailing assistant, this path now returns a context with that compaction payload removed, which can drop critical summary/tool-loop guidance for the next provider call.

Useful? React with 👍 / 👎.

Remove assistant-trim issues from MOIM allowlist

Allowlisting "Removed leading assistant message"/"Removed trailing assistant message" here lets inject_moim accept fix_conversation outputs that delete assistant turns instead of falling back to the original conversation. In recovery compaction when no trailing text-only user message is preserved, compact_messages builds the compacted context as assistant summary + assistant continuation (crates/goose/src/context_mgmt/mod.rs:151-167), so accepting a trailing-assistant removal drops the only compacted payload before the next provider call. Fresh evidence: those two compaction assistant messages are merged into one assistant turn there, so removing that turn deletes both the summary and tool-loop continuation guidance.

PR #7684 Review: fix: widen MOIM allowlist to apply fix_conversation repairs

Summary: This PR fixes a real bug where orphaned tool blocks caused a "death loop" of API 400 errors. The core fix (widening the allowlist) is correct, but the PR description claims to include tests that are not present in the diff.

🔴 Blocking Issues

Missing tests mentioned in PR description [moim.rs]

The PR description states:

"Adds 2 tests in moim.rs: test_moim_fixes_orphaned_tool_request (core allowlist fix), test_moim_fixes_cancellation_orphan (production scenario with empty pre-allocated user message)"

These tests are not in the diff and not in the codebase:
```
$ rg "test_moim_fixes_orphaned_tool_request|test_moim_fixes_cancellation_orphan" --type rust
# (no output)
```
The only test added is test_compaction_output_with_new_tool_pair_is_valid in context_mgmt/mod.rs. The core fix (orphan handling in MOIM) lacks direct test coverage.

Action required: Either add the missing tests or update the PR description. Tests for the actual bug being fixed (orphaned tool blocks causing MOIM rejection) are important for preventing regression.

🟡 Warnings

PR description claims "all fix_conversation repair types" but adds a subset [moim.rs:35-43]

The PR adds 6 specific issue patterns to the allowlist, but fix_conversation can emit ~14 different issue types. The excluded ones include:
- "Trimmed trailing whitespace from assistant message"
- "Removed tool request '{}' from user message"
- "Removed thinking content from user message"
- "Added placeholder user message to empty conversation"
This is likely intentional (these indicate structural corruption unlikely from MOIM injection), but the PR description should say "relevant repair types" rather than "all" for accuracy.

✅ Highlights

Good logging addition: The tracing::info! when fixes are applied (line 51-53) will help debugging without cluttering logs on success.
Correct allowlist logic: Using .contains() properly matches the parameterized issue strings (e.g., "Removed orphaned tool response 'id'" matches "Removed orphaned tool response").
Well-structured regression test: test_compaction_output_with_new_tool_pair_is_valid clearly documents its purpose and validates compaction output integrity.

Remove assistant-trim issues from MOIM allowlist

Allowing "Removed leading assistant message" and "Removed trailing assistant message" here makes inject_moim accept fix_conversation results that delete assistant turns instead of falling back to the original conversation. Fresh evidence: compact_messages constructs the compacted payload as assistant summary + assistant continuation (crates/goose/src/context_mgmt/mod.rs around lines 151-167), and in the no-preserved-user path fix_lead_trail removes both assistant endpoints after MOIM inserts a user message between them, so the next provider call can lose the entire compacted summary/tool-loop guidance.
