## Intake summary
|
|
|
|
既存 Ticket は、closed 済みの `20260609-032533-001` で追加された `session-analytics` 基盤への concrete follow-up として十分に具体化済み。目的は assistant response 単位の tool batching / edit round-trip 指標を JSON report に追加することで、実装対象 metrics、断定しない diagnostics 方針、非目標、受け入れ条件、テスト観点が明記されている。未決定の product/API/authority boundary はなく、Orchestrator は implementation_ready として routing できる。Reviewer focus は、response/tool-result cycle 推定の妥当性、raw content を出さない既存 analytics privacy boundary の維持、consecutive edit-only streak の過剰断定回避、既存 CLI/JSON schema との整合性。

## Decision
|
|
|
|
Routing decision: implementation_ready_parallel
|
|
|
|
Reason:
|
|
- This Ticket extends `session-analytics`, a recently landed and currently inactive area.
|
|
- It is independent from active ToolExecutionContext, TicketList output, and Panel UX work.
|
|
- User asked to prefer parallel work when conflicts are absent or expected small.
|
|
|
|
IntentPacket:
|
|
|
|
Intent:
|
|
- Add assistant-response-level tool batching and edit round-trip metrics to `session-analytics` so tool-use speed patterns can be evaluated in structured JSON.
|
|
|
|
Binding decisions / invariants:
|
|
- Infer assistant response / tool-result cycle units from session JSONL as best-effort analytics.
|
|
- Add response-level tool call metrics: total responses, tool-call responses, total tool calls, avg/p50/p90/max, histogram, top responses by tool call count.
|
|
- Add edit batching metrics: Edit calls per response, responses containing Edit, same-file multiple Edit calls in one response, files touched per edit response, and correlation with large edit args where possible.
|
|
- Add consecutive edit-only response streak metrics by file/path and response range, distinguishing pure edit-only streaks from sequences broken/annotated by Read/Bash/test/result-dependent steps.
|
|
- Diagnostics must be observations such as possible batching opportunity, not blame or policy enforcement.
|
|
- Preserve existing privacy boundary: no raw user input, raw tool args, raw file contents, raw session snippets, or raw tool output content in default output.
|
|
- Do not change prompt/workflow behavior, implement EditBatch/ordered patch tools, or force batching policy.
|
|
|
|
Validation:
|
|
- Tests for single response with multiple tools.
|
|
- Tests for same-response same-file multiple Edit.
|
|
- Tests for consecutive edit-only responses to same file.
|
|
- Tests for interleaved Read/test step breaking or annotating streak.
|
|
- Tests for sessions with no edits.
|
|
- `cargo fmt --check`, `git diff --check`, `cargo run -q -p yoi -- ticket doctor`, `cargo check --workspace`, `nix build .#yoi`.

## Implementation report
|
|
|
|
Implementation routing started in parallel with the current active work set.
|
|
|
|
Worktree/branch:
|
|
- Worktree: `.worktree/session-analytics-response-batching`
|
|
- Branch: `session-analytics-response-batching`
|
|
- Base/routing commit: `5d9e227 ticket: route analytics batching and parallel guidance`
|
|
|
|
Spawned sibling Coder Pod:
|
|
- `coder-session-analytics-response-batching`
|
|
- Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree.
|
|
|
|
Parallel-routing rationale:
|
|
- This extends the isolated `session-analytics` crate/CLI surface and is independent from active ToolExecutionContext/TicketList/Panel work.
|
|
- Coder was instructed to use synthetic fixtures and preserve the privacy boundary.

## Implementation report
|
|
|
|
Coder implementation completed and is ready for sibling review.
|
|
|
|
Coder Pod:
|
|
- `coder-session-analytics-response-batching`
|
|
- Commit: `963db29d960d23b40e32d6b07db88f52b914a72d analytics: add response batching metrics`
|
|
- Worktree status before review: clean branch `session-analytics-response-batching`
|
|
- Stopped after collecting output to reclaim delegated worktree scope.
|
|
|
|
Response boundary design:
|
|
- Best-effort response grouping uses consecutive top-level `kind: "assistant_item"` JSONL entries as one assistant response.
|
|
- Non-assistant entries such as `tool_result`, `turn_end`, or `segment_start` close the current response group.
|
|
- Seeded `segment_start.history` is excluded from response-level metrics because exact original response boundaries are not explicit; a `response_boundary_approximation` diagnostic records this limitation.
|
|
- Metrics live under `response_batches` and remain distinct from user-turn metrics.
|
|
|
|
Implementation summary:
|
|
- Added response-level tool metrics: total responses, tool-call responses, total tool calls, avg/p50/p90/max tools per response, histogram, and top tool-call responses.
|
|
- Added Edit batching metrics: responses containing Edit, total Edit calls, calls per response, same-file multi-Edit responses, files touched per Edit response, large-argument summary fields, and `replace_all` count.
|
|
- Added consecutive edit round-trip metrics: pure same-file edit-only streaks and interrupted/annotated sequences when Read/Bash/test-like steps intervene.
|
|
- Preserved privacy boundary: no raw user input, raw tool args, raw file contents, raw session snippets, or raw tool output content in default JSON output.
|
|
|
|
Changed files:
|
|
- `crates/session-analytics/src/lib.rs`
|
|
- `crates/yoi/src/session_cli.rs`
|
|
|
|
Coder validation reported passed:
|
|
- `cargo test -p session-analytics`
|
|
- `cargo test -p yoi run_session_analyze_outputs_json`
|
|
- `cargo fmt --check`
|
|
- `git diff --check`
|
|
- `cargo run -q -p yoi -- ticket doctor`
|
|
- `cargo check --workspace`
|
|
- `nix build .#yoi`
|
|
|
|
Focused tests covered multiple tools in one response, same-response same-file edits, consecutive edit-only responses, interleaved Read/test-like Bash interruption/annotation, sessions with no edits, existing analytics behavior, and CLI JSON shape.
|
|
|
|
Residual notes:
|
|
- Response boundaries are best-effort for current JSONL shape.
|
|
- Percentile/avg output is count-based and `avg_milli` avoids floating-point JSON instability.
|
|
- Bash test detection is heuristic and only annotates interrupted edit sequences; it is not blame/policy classification.

Reviewed commit `963db29d960d23b40e32d6b07db88f52b914a72d` against Ticket `20260609-085148-001`.
|
|
|
|
Evidence:
|
|
- Diff scope is limited to `crates/session-analytics/src/lib.rs` and `crates/yoi/src/session_cli.rs`; no prompt, workflow, tool behavior, or batching-policy/enforcement changes were introduced.
|
|
- `SessionReport` exposes `response_batches` in JSON with response-level tool metrics, histogram/top responses, nested Edit batching metrics, and edit round-trip/annotated-sequence metrics.
|
|
- Response grouping is best-effort over contiguous top-level `assistant_item` entries; non-assistant entries close the response. Seeded `segment_start.history` tool calls are excluded from response metrics and add a `response_boundary_approximation` diagnostic.
|
|
- New observations use bounded diagnostic language such as “possible batching opportunity” / “not automatic blame”; no policy enforcement or judgment of small edits is present.
|
|
- Privacy boundary was checked with a synthetic JSONL fixture containing sentinel raw `old_string`, `new_string`, and tool output content. The JSON report preserved paths/counts/sizes/indexes and did not include the raw sentinel values.
|
|
- Tests added synthetic fixtures for response-level tool grouping, same-file multi-Edit response metrics, pure consecutive edit-only streaks, Read/Bash/test-like interrupted sequences, no-edit sessions, and CLI JSON field exposure.
|
|
|
|
Validation run from the worktree:
|
|
- `cargo test -p session-analytics`
|
|
- `cargo test -p yoi run_session_analyze_outputs_json`
|
|
- `cargo fmt --check`
|
|
- `git diff --check`
|
|
- `cargo check --workspace`
|
|
- custom synthetic JSON/privacy assertion using `target/debug/yoi session analyze --json`
|
|
- `cargo run -q -p yoi -- ticket doctor`
|
|
- `nix build .#yoi`
|
|
|
|
Residual risk:
|
|
- Assistant response boundaries remain inherently approximate because session JSONL does not carry an explicit response id; the implementation reports this for seeded history and otherwise keeps the metrics best-effort rather than authoritative.
|
|
|
|
No blocking issues found.

## Review: approve
|
|
|
|
Review result: approve
|
|
|
|
Evidence:
|
|
- Change scope is limited to `crates/session-analytics/src/lib.rs` and `crates/yoi/src/session_cli.rs`; no prompt/workflow behavior, tool behavior, or batching policy enforcement was added.
|
|
- JSON report adds machine-readable `response_batches` fields covering response-level metrics, Edit batching metrics, and edit round-trip metrics.
|
|
- Assistant response boundary is clearly best-effort: consecutive top-level `assistant_item` entries are grouped, non-assistant entries close a response, and seeded `segment_start.history` tool calls are excluded from response-level metrics with a `response_boundary_approximation` diagnostic.
|
|
- Diagnostics are observational (`possible batching opportunity` / not automatic blame), not policy enforcement or blame for small edits.
|
|
- Synthetic privacy fixture with raw `old_string`, `new_string`, and tool output sentinel was analyzed via `yoi session analyze --json`; raw sentinel content did not appear in output. Output stays at paths/counts/sizes/indexes/line ranges.
|
|
- Tests are synthetic/minimal fixtures, not private local sessions. They cover response grouping, same-file multi-Edit, pure consecutive edit-only streaks, Read/Bash/test-like interruption, no-edit case, and CLI JSON exposure.
|
|
|
|
Reviewer validation:
|
|
- `cargo test -p session-analytics`
|
|
- `cargo test -p yoi run_session_analyze_outputs_json`
|
|
- `cargo fmt --check`
|
|
- `git diff --check`
|
|
- `cargo check --workspace`
|
|
- custom synthetic JSON/privacy assertion using `target/debug/yoi session analyze --json`
|
|
- `cargo run -q -p yoi -- ticket doctor`
|
|
- `nix build .#yoi`
|
|
|
|
Residual risk:
|
|
- Session JSONL lacks explicit response ids, so response boundaries are inherently approximate. The implementation reports this boundedly and treats the feature as best-effort analytics, which is acceptable for this Ticket.
