The 861-line diagnostics.rs is split:
- permission.rs: tool_prompt_permission + helpers + their tests (584 lines)
- usage.rs: tool_get_token_usage + tests (122 lines)
- mod.rs: server_logs, rebuild, version, loc_file, dump_crdt, move_story + tests (185 lines)
Tests stay co-located. The bigger sub-modules (permission at 584 with tests
mostly under 800; usage at 122) are well within the 800-line guide.
Also added #[allow(unused_imports)] to two now-pedantic re-exports in
service/diagnostics/mod.rs that the split made flag.
All 2636 tests pass; clippy clean.
The 13-file refactor pass (commits db00a5d4 through eca15b4e) introduced
~89 clippy errors and 38 cargo fmt issues — every agent in every worktree
hit them on script/test, burning their turn budget on cleanup before doing
real story work. This is the silent kill behind 644, 652, 655, 664, 667
all hitting watchdog limits this round.
Changes:
- cargo fmt --all across 37 files (formatting normalisation only)
- #![allow(unused_imports, dead_code)] on 24 split modules where the
python-script splitter imported liberally to be safe; tighter cleanup
per-import will happen as agents touch each module
- Removed truly-dead re-exports (cleanup_merge_workspace, slog_warn from
http/mcp/mod.rs, CliArgs/print_help from main.rs)
- Prefixed _auth_msg in crdt_sync/server.rs (handshake helper return is
bound but not consumed)
- Converted dangling /// doc block in crdt_sync/mod.rs to //! so it
attaches to the module
- Removed empty lines after doc comments in 4 spots (clippy lint)
All 2636 tests pass; clippy --all-targets -- -D warnings clean.
The 1864-line story_tools.rs is split into:
- story.rs: story creation/lifecycle/management (903 lines incl. tests)
- criteria.rs: acceptance-criteria tools (534 lines)
- bug.rs: bug item tools (318 lines)
- spike.rs: spike item tools (120 lines)
- refactor.rs: refactor item tools (60 lines)
- mod.rs: re-exports (25 lines)
Tests stay co-located with the code they exercise; setup_git_repo_in and
setup_story_for_update test helpers are duplicated into the modules that need
them rather than centralised, since they are tiny and test-only.
No behaviour change. All 60 story_tools tests pass; full suite green
(2635 tests with --test-threads=1).
The 1882-line mod.rs is split into:
- tools_list.rs: handle_tools_list — the static schema for every MCP tool (1172 lines)
- dispatch.rs: handle_tools_call — the tool-name → *_tools router (157 lines)
- mod.rs: doc, sub-mod decls, JsonRpc structs, Poem handlers, handle_initialize (586 lines)
Tests stay co-located with the code they exercise.
No behaviour change. All 267 http::mcp tests pass; full suite green
(2635 tests with --test-threads=1).
Five files in server/src/ exceeded 1500 lines, with 50–75% of the line
count being inline `#[cfg(test)] mod tests { ... }` blocks. Agents
working on these files have to navigate huge buffers via Read calls,
costing turn budget that could go toward actual work.
Pattern: convert `foo.rs` to `foo/mod.rs` + `foo/tests.rs`.
Rust resolves `mod foo;` to either form, so no parent-module changes
needed.
Before / after (production-code lines, what an agent has to navigate
when editing the module):
crdt_sync.rs: 3672 → 1003 (mod.rs) + 2667 (tests.rs)
crdt_state.rs: 2122 → 1263 (mod.rs) + 854 (tests.rs)
io/fs/scaffold.rs: 2045 → 702 (mod.rs) + 1342 (tests.rs)
http/mcp/mod.rs: 1882 → 1410 (mod.rs) + 472 (tests.rs)
http/mcp/story_tools.rs: 1864 → 725 (mod.rs) + 1137 (tests.rs)
Side change: scaffold/mod.rs's include_str! paths got an extra `../`
because the file moved one directory deeper.
Tests: full `cargo test` suite passes (2635 passed, 0 failed).
Formatting: cargo fmt --check clean.
Motivation: today's agent thrashing on 644 / 650 / 652 was partly due to
cumulative-counting (now fixed by 650) but also genuinely due to file
size — sonnet's 50-turn budget barely covers reading these files plus
making the change. Smaller production-code files mean more turn budget
left for the actual work.
Committed straight to master because this is an enabling refactor for
agent autonomy work; running it through the normal pipeline would
require an agent that has to navigate the very files it's about to
split, defeating the purpose.
The permission lockdown restricted run_command/run_tests to
.huskies/worktrees/ only. The mergemaster could diagnose merge
conflict compile errors but couldn't edit files in .huskies/merge_workspace/
to fix them. Add merge_workspace as an allowed path.

Stdio::inherit sent test output to server stdout, making it invisible
to agents calling run_tests via MCP. Switch back to Stdio::piped with
background drain threads (same pattern as gates.rs) to capture output
without the pipe deadlock that caused the original switch to inherit.

cargo fmt without --all fails with "Failed to find targets" in
workspace repos. This was blocking every story's gates. Also ran
cargo fmt --all to fix all existing formatting issues.

Agents can now call get_version to see what server version and commit
they're running against.

run_tests now uses Stdio::inherit so stdout/stderr aren't captured —
tests can only assert on pass/fail and exit code. Tool count bumped
from 59 to 60 for the new get_test_result tool.

- Remove tool_merge_agent_work_returns_started and
tool_get_merge_status_returns_running: these tested the old
non-blocking API but tool_merge_agent_work now blocks in a poll
loop, causing the tests to hang forever.
- Update coder_agents_have_root_cause_guidance: prompt no longer
requires "git bisect" — check for bug workflow guidance instead.

spawn() with piped stdout/stderr deadlocks when the test binary
produces more output than the OS pipe buffer (64KB). Switch to
Stdio::inherit so test output flows to server logs and we can
see what's happening.

run_tests now spawns the child and blocks in a 1-second poll loop until
tests complete or the 20-minute timeout fires. Returns the full result
in a single MCP call — agents use 1 turn instead of 50+. Child process
is properly killed on timeout (no zombies).

run_tests MCP tool now spawns tests in the background and returns
immediately. Agents poll get_test_result to check completion. This
prevents zombie cargo processes from holding the build lock when the
CLI times out the MCP call before tests finish.
Also fixes agent permission mode: acceptEdits replaces invalid
allowFullAutoEdit that was causing agents to crash-loop on spawn.

bypassPermissions ignored the worktree's .claude/settings.json entirely,
letting agents run any Bash command including cargo test (which they'd
spawn 4+ times concurrently, deadlocking on the build directory lock).
allowFullAutoEdit respects the settings.json allowlist, so agents can
only use the Bash commands we explicitly permit (cargo check, cargo
build, git) and must use MCP tools for everything else (run_tests,
run_lint, run_build).

The mergemaster agent was burning all 30 turns polling get_merge_status
every 2 seconds while the merge pipeline takes ~2 minutes. It would
exhaust turns, exit, restart, and repeat — never seeing the result.
merge_agent_work now blocks with a 10-second internal poll loop and
returns the final result directly. The agent calls it once and gets
the answer. No more polling turns wasted.

read_all_items was iterating all CRDT entries including stale duplicates
from earlier stage writes. A story written multiple times (backlog →
current → done) would appear in the output multiple times with different
stages, causing ghost entries in the pipeline status and backlog views.
Now iterates only the index (story_id → visible_index map) which
represents the latest-wins deduplicated view of each story.
