## 作成 LocalTicketBackend によって作成されました。 --- ## Intake summary 既存 Ticket は、closed 済みの `00001KTN6KYY8` 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。 --- ## State changed Intake で既存 Ticket の本文・thread・artifacts と関連する closed Ticket `00001KTN6KYY8` を確認した。要件は実装・レビュー・検証できる粒度まで整理済みであり、planning から ready にする。 --- ## State changed Ticket を `workspace-panel` が queued にしました。 --- ## State changed Accepted queued implementation under the updated parallel-capacity policy. This Ticket extends the already-landed session analytics crate and is independent from the active ToolExecutionContext, TicketList, and Panel worktrees. --- ## 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. --- ## Review: approve ## Review result: approve Reviewed commit `963db29d960d23b40e32d6b07db88f52b914a72d` against Ticket `00001KTNS9B50`. 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. --- ## State changed Ticket を closed にしました。 --- ## 完了 Implemented, reviewed, merged, and validated.
