Intake summary

既存 Ticket は、session JSONL を read-only に解析する再利用可能な session-analytics crate と薄い yoi session analyze <path> --json CLI を追加する concrete work item として十分に具体化済み。初期対象 metrics、raw content を既定で出さない privacy/secret 境界、non-goals、受け入れ条件、検証項目が明記されており、Orchestrator が実装 routing を判断できる。関連する prompt-eval-metrics は評価/改善 offer 寄りであり、本 Ticket は低レベル session/tool analytics 基盤として重複ではない。

State changed

Intake で要件が実装 routing 可能な粒度まで整理済みであることを確認したため、planning から ready にします。

State changed

Ticket を workspace-panel が queued にしました。

State changed

Accepted queued implementation after reading the Ticket body/thread and current workspace state. The Ticket has concrete library/CLI/report/privacy acceptance criteria and does not depend on the just-landed Objective work. Implementation can proceed with synthetic fixture tests and read-only analysis semantics.

Decision

Routing decision: implementation_ready

Evidence checked:

  • Ticket body and Intake summary.
  • Current workspace state after Objective records merged, closed, and cleaned up.
  • Current worktree state: no active implementation worktree remains.
  • Current queued set: this is the only queued Ticket.

Reason:

  • The Ticket is specific enough for implementation: add a reusable session-analytics crate, structured report model, and thin yoi session analyze <path> --json CLI.
  • The privacy boundary is explicit: default output must not dump raw user input, file contents, secrets, or raw session snippets.
  • The non-goals are clear: no pruning/compaction behavior changes, no TUI dashboard, no prompt/tool guidance auto-rewrite, no LLM semantic summarization.

IntentPacket:

Intent:

  • Add read-only session JSONL analytics that extracts structured tool/session metrics and suspicious-pattern diagnostics without exposing raw content by default.

Binding decisions / invariants:

  • Add a reusable library crate, e.g. crates/session-analytics, with an API such as analyze_session(path) -> SessionReport.
  • Add a thin product CLI surface, e.g. yoi session analyze <session-jsonl-or-path> --json, that calls the library and avoids duplicating analytics logic.
  • Prefer streaming/bounded parsing for large JSONL files; do not unnecessarily read huge files into memory if line-by-line parsing is practical.
  • Analysis is read-only and has no runtime side effects.
  • The analytics crate must stay independent from TUI rendering and Pod runtime side effects; runtime crates must not depend on analytics.
  • Reuse current session/log schema types only where dependency direction remains healthy.
  • Structured report should include at least:
    • tool usage counts by name/kind;
    • tool calls per turn;
    • failed tool call counts;
    • repeated Read by path and by path+offset/limit;
    • whether repeated reads had intervening write/edit observations;
    • edit/write churn by path;
    • edit/write argument byte-size estimates and large replacement diagnostics;
    • replace_all usage;
    • observable tool result sizes/large/truncated indicators where available;
    • prune/compaction events and bounded correlation with subsequent repeated reads/tool calls;
    • malformed/unknown entry diagnostics.
  • Suspicious diagnostics must be framed as observations, not automatic blame. Re-reading after mutation or validation may be correct.
  • Default CLI/report output must avoid raw user input/file contents/session snippets. It may include paths, counts, byte sizes, turn/timestamp indexes, and hashes if useful.
  • Tests should use synthetic/minimal session JSONL fixtures rather than relying on private local sessions.
  • Do not implement a full dashboard, prompt auto-fixer, semantic summarizer, or Worker pruning/compaction behavior changes.

Implementation latitude:

  • Coder may choose exact report struct field names and JSON format if machine-readable and test-covered.
  • Coder may add a small JSONL adapter tolerant of unknown/malformed records with bounded diagnostics if current session log enum parsing is too strict.
  • Coder may keep initial path input file-only; --latest, --pod, directory aggregation, and Markdown output can remain future work.
  • If current session schema is too hard to reuse without unhealthy dependencies, implement a minimal analytics event parser for the observed JSONL shape and document the limitation.

Escalate if:

  • Implementing this requires changing session writer/history schemas or Worker compaction behavior.
  • Avoiding raw-content exposure conflicts with required metrics.
  • Healthy crate dependency direction would require a larger session-schema extraction refactor.
  • Real local session data would need to be read for tests/validation; use synthetic fixtures instead unless explicitly authorized.

Validation:

  • Focused unit tests for repeated reads with/without intervening edit/write.
  • Focused tests for large edit argument sizing and replace_all observations.
  • Focused tests for tool failure counting and tool calls per turn.
  • Focused tests for large/truncated result observations if representable in fixtures.
  • Focused tests for compaction/prune event correlation as correlation only.
  • Focused tests for malformed/unknown JSONL entries producing bounded diagnostics.
  • CLI JSON output test for yoi session analyze <path> --json or equivalent.
  • cargo fmt --check.
  • git diff --check.
  • cargo run -q -p yoi -- ticket doctor.
  • cargo check --workspace.
  • nix build .#yoi.

Implementation report

Implementation routing started.

Worktree/branch:

  • Worktree: .worktree/session-analytics-tooling
  • Branch: session-analytics-tooling
  • Base/routing commit: c166140 ticket: route session analytics tooling

Spawned sibling Coder Pod:

  • coder-session-analytics-tooling
  • Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree.

Routing context:

  • This Ticket is now the active implementation work.
  • Handoff explicitly requires synthetic/minimal session fixtures for validation and avoids reading private real local session contents.

Implementation report

Coder implementation completed and is ready for sibling review.

Coder Pod:

  • coder-session-analytics-tooling
  • Commit: c1809b37b1816a73e18c7587b9952cf4fc7b43f3 feat: add session analytics tooling
  • Worktree status before review: clean branch session-analytics-tooling
  • Stopped after collecting output to reclaim delegated worktree scope.

Selected design:

  • Added crates/session-analytics with public analyze_session(path) -> SessionReport.
  • Parser is a tolerant serde_json::Value JSONL parser using BufReader::lines() instead of tightly coupling analytics to runtime schema enums.
  • Report avoids raw user input, raw tool arguments, raw file contents, and raw tool output snippets by default; it reports paths, counts, byte/line sizes, line/turn indexes, bounded diagnostics, and observation text.
  • Added thin CLI yoi session analyze <SESSION_JSONL_PATH> --json that delegates to the library crate.

Implementation summary:

  • Tool usage summary: counts by tool name/kind, calls per turn, failed tool result count, and Bash file-inspection-like heuristic observations.
  • Repeated reads: by path and path+offset/limit, with intervening Edit/Write observation and post-context-lifecycle correlation.
  • Edit/write churn: counts by path, repeated edits, argument byte-size estimates, large replacement diagnostics, and replace_all observations.
  • Tool result size: output byte/line sizes, large result observations, and saved/truncated Bash result indicators.
  • Context lifecycle: observes segment_start.compacted_from and context/prune/compact-like extension events; correlation only, not causation.
  • Robustness: malformed/unknown JSONL entries produce bounded diagnostics; unreadable input file remains an error.

Changed files:

  • Cargo.toml
  • Cargo.lock
  • package.nix
  • crates/session-analytics/Cargo.toml
  • crates/session-analytics/src/lib.rs
  • crates/yoi/Cargo.toml
  • crates/yoi/src/main.rs
  • crates/yoi/src/session_cli.rs

Coder validation reported passed:

  • cargo test -p session-analytics
  • cargo test -p yoi session_cli
  • cargo test -p yoi parse_session_analyze_uses_session_mode
  • cargo fmt --check
  • git diff --check
  • git diff --cached --check
  • cargo run -q -p yoi -- ticket doctor -> doctor: ok
  • cargo check --workspace
  • nix build .#yoi
  • result/bin/yoi session analyze --help

Residual risks noted by coder:

  • Parser is intentionally tolerant and may emit more diagnostics if future session JSONL shapes change.
  • Context lifecycle support is based on currently observable segment_start.compacted_from and context/prune/compact-like extension events.
  • Bash file-inspection detection is a lightweight heuristic and should be treated as an observation, not automatic blame.

Review: approve

Review result: approve

Reviewed commit c1809b37b1816a73e18c7587b9952cf4fc7b43f3 on branch session-analytics-tooling in worktree .worktree/session-analytics-tooling.

Evidence

  • The implementation adds crates/session-analytics with public analyze_session(path) -> SessionReport and a tolerant JSONL parser using BufReader::lines() / per-line serde_json::Value parsing.
  • The product CLI adds a thin yoi session analyze <SESSION_JSONL_PATH> --json surface through crates/yoi/src/session_cli.rs; analytics logic remains in the library crate.
  • Changed files are limited to workspace/package metadata, the new analytics crate, and the top-level product CLI wiring. I did not find changes to Worker pruning/compaction, Pod protocol/history/session writer semantics, TUI dashboarding, prompt auto-fixing, or summarization behavior.
  • Dependency direction is healthy for this Ticket: session-analytics depends only on serde, serde_json, and thiserror plus test tempfile; cargo tree -i session-analytics --workspace shows the product yoi crate as the consumer, not runtime/TUI crates.
  • Privacy boundary checked with a synthetic fixture containing secret-like user/file/tool argument/tool output strings. JSON output did not include raw Read content, Edit old/new strings, Bash command arguments, or Bash result content; it emitted paths, counts, byte/line sizes, line/turn indexes, and bounded observations.
  • Malformed and unknown JSONL entries are counted and surfaced as bounded diagnostics instead of crashing the whole report; unreadable input remains an error.
  • Tests are synthetic/minimal fixtures in the new crate / CLI tests, not private local sessions.

Validation run

Passed:

  • cargo test -p session-analytics
  • cargo test -p yoi session_cli
  • cargo test -p yoi parse_session_analyze_uses_session_mode
  • synthetic CLI JSON privacy/metrics assertion fixture created during review
  • cargo fmt --check
  • git diff --check HEAD~1..HEAD
  • cargo check --workspace
  • nix build .#yoi
  • result/bin/yoi session analyze --help
  • git diff --exit-code / git status --short clean after review

Residual risks / notes

  • Tool result size reporting is most detailed for large-result and truncated/saved Bash observations; this meets the Ticket acceptance focus, but future aggregation could add per-tool output-size histograms if analysis needs it.
  • Repeated-read and Bash-file-inspection diagnostics are correctly framed as observations/correlations rather than automatic blame.
  • The new top-level session subcommand reserves that literal bare token; explicit --pod session remains the escape hatch for a Pod named session.
