Session Review (#131)

Role: orchestrator. Mines ground-truth session transcripts and routes suggestions into existing machinery — it suggests, never auto-applies, and preserves every human gate.

Every metrics/*.jsonl/.json schema referenced below (including pending-review.jsonl and the boundary-level boundary-events.jsonl block/ warn/bypass/intervention causes, #859) is documented in full at ${CLAUDE_PLUGIN_ROOT}/knowledge/telemetry-schema.md — read it before reasoning about a stream's fields ad hoc.

You have been invoked with the /session-review command.

Orchestrator constraints

1. Never read raw transcripts yourself. All heavy parsing is the deterministic extractor's job; you read only its KB-sized digest. Spending model tokens to study token spend defeats the purpose. The one exception is the gated raw-log tier (Step 2b): even there you never read a raw log — you dispatch one isolated sub-agent per flagged log and keep only its metrics-only findings.
2. Suggest, never apply. Output a ranked report and hand off; do not edit agents, skills, or config. Human gates stay intact.
3. Metrics only. The digest and report contain counts/ratios/names — never prompt or code content.

Argument: $ARGUMENTS

• --cwd <path>: project whose transcripts to mine (default: current project).
• --transcript <file>: analyze a specific transcript instead of auto-resolving.
• --out <report>: report path (default: reports/session-review-<date>.md).

Steps

0. Queued Findings — surface pending-review queue before fresh analysis

Before running fresh analysis, check whether background analysis has produced findings that are waiting for review.

1. Check metrics/pending-review.jsonl for entries where reviewed_at is absent. Count them and note their queued_at timestamps.

2. If one or more unreviewed entries exist, display a Queued Findings section:

   ## Queued Findings (N unreviewed)
   
   | # | queued_at | source | findings |
   |---|-----------|--------|----------|
   | 1 | <ts>      | <src>  | <count>  |
   

   Then offer: "Run /feedback-learning to approve or reject each queued finding before proceeding with fresh analysis."

3. If metrics/pending-review.jsonl does not exist, or all entries have reviewed_at, skip this section silently and proceed.

4. If any JSONL lines are malformed, skip those lines, emit a one-line warning (WARN: skipped N malformed line(s) in pending-review.jsonl), and continue with the valid entries.

pending-review.jsonl Schema

Full field reference: ${CLAUDE_PLUGIN_ROOT}/knowledge/telemetry-schema.md (pending-review.jsonl section). Summary — each line is a JSON object:

{
  "queued_at":  "2026-06-01T12:00:00Z",
  "source":     "session-learning-trigger",
  "session_id": "abc-123",
  "findings": [
    {
      "lever":           "instruction-rule",
      "evidence":        "3 occurrences in last 5 sessions",
      "target_artifact": "agents/orchestrator.md",
      "proposed_change": "Add constraint: always load context-loading-protocol first",
      "route":           "feedback-learning"
    }
  ]
}

Optional fields added by /feedback-learning after disposition:

• reviewed_at (ISO-8601 UTC) + approved_by — written on approval
• rejected_at (ISO-8601 UTC) + rejected_by — written on rejection

1. Cross-machine Telemetry — validate config, then sync (#178)

Before analysing, check whether a telemetry repository (the cross-machine "database", Delta D) is configured, so the digest reflects every machine, not just this one:

bash ${CLAUDE_PLUGIN_ROOT}/../../scripts/telemetry-sync.sh --check

• Exit 0 → a repo is configured. Run the sync to push this machine's digest and pull the others, then continue:

  bash ${CLAUDE_PLUGIN_ROOT}/../../scripts/telemetry-sync.sh
  

• Exit 3 → no repo configured. Ask the user for the telemetry repo location (a git URL), e.g. "Where should cross-machine telemetry be stored? Paste a private git repo URL, or say 'skip' to review this machine only."

  • If they give a URL, write it to ~/.claude/.dev-team/telemetry.json as { "remote": "<url>" } (create the dir if needed), confirm, then run the sync command above. Point them at telemetry-repo-security.md for the one-time deploy-key/token setup.
  • If they say skip, proceed local-only — do not block the review.

Never invent a URL or enable anything without the user's explicit location.

2. Extract (deterministic, zero model tokens)

Run the extractor to produce the digest:

python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/session_extract.py \
  --plugin-root ${CLAUDE_PLUGIN_ROOT} -o memory/session-digest.json

(Pass --transcript <file> or --cwd <path> through from $ARGUMENTS.) If the extractor finds no transcripts, tell the user and stop — nothing to review.

If a telemetry repo synced in Step 0, also build the cross-machine rollup (the union of every host's digest, #178) and prefer it for analysis — it sees all machines and projects, not just this one:

CLONE="${DEV_TEAM_TELEMETRY_CLONE:-$HOME/.claude/.dev-team/agent-telemetry}"
python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/session_extract.py \
  --plugin-root ${CLAUDE_PLUGIN_ROOT} --rollup "$CLONE/digests" \
  -o memory/telemetry-rollup.json

The rollup is metrics-only (telemetry-rollup/v1): per-host and per-project token/cost, summed rework/accuracy, and skills/agents never invoked on any machine. Hand the analysis agent the rollup when present, the local digest otherwise.

Then compute the frequency → lever escalation (Delta C, #179) — recurrence decides how strong a response each friction earns:

python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/session_extract.py \
  --plugin-root ${CLAUDE_PLUGIN_ROOT} --escalate "$CLONE/digests" \
  -o memory/telemetry-escalation.json

Each recommendation carries a lever: hint (rare — surface only), instruction-rule (recurring; hand to /feedback-learning), or hook (frequent and deterministically matchable; validate via /agent-eval before shipping). "Matchable" is the deterministic side of the rules-vs-prompts ≤10% FP policy. Use the escalation lever to set the hand-off in Step 3.

Optionally compute the gate correlation (process eval, #111) — does bypassing the pre-commit review gate correlate with more rework across sessions?

python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/session_extract.py \
  --plugin-root ${CLAUDE_PLUGIN_ROOT} --correlate "$CLONE/digests" \
  -o memory/gate-correlation.json

This compares mean rework between bypass and non-bypass committing sessions. It is correlational, not causal — surface it as evidence for whether the review gate earns its place (feeds the ADR-0006 decision, #112), never as proof.

3. Analyze (digest-only)

Dispatch the session-analysis agent with the digest path as its sole input. The agent maps aggregated patterns to probable plugin causes and returns ranked suggestions, each tagged {token | rework | accuracy} with a named target artifact and a hand-off destination. The agent reads only the digest.

3b. Raw-log semantic tier — only the worst sessions (#214, Delta A/B)

The digest is quantitative, so it is blind to frictions with no count-signature — a hallucinated citation (the AI cited a skill/source that does not exist), or an operator habit (deferring decisions with no owner). Surface those with a bounded second tier: the deterministic digest decides where it is worth spending tokens, then you read only those few raw logs. This tier needs the cross-machine digests (the $CLONE/digests from Step 0); if no telemetry repo synced, skip it.

1. Flag the worst sessions (deterministic, zero model tokens):

   python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/eval_rawlog.py \
     --flag "$CLONE/digests" --top 5 -o memory/worst-sessions.json
   

   If it flags nothing, skip this tier — there is nothing expensive to read.

2. For each flagged session_id only, locate its raw transcript (~/.claude/projects/**/<session_id>.jsonl) and dispatch one sub-agent per transcript (one ~1MB log = one agent = one context boundary; fan out in parallel). Each sub-agent reads its single raw log and returns semantic frictions the digest cannot see. You never read the raw log yourself (constraint 1); the raw log never leaves the machine. Require each finding in the metrics-only shape the validator enforces — only these keys: {lens, friction_type, target_artifact, confidence, count} (plus optional session_id/project/host), with lens ∈ {methodology, harness, devex, accuracy}. A finding may say that a friction occurred and which artifact to fix, never a prompt, code, path, or quote.

3. Mechanically verify the privacy boundary before keeping anything — drop (do not report) any finding with violations:

   python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/eval_rawlog.py \
     --validate memory/tier2-findings.json
   

4. Suggest (write the report)

Write reports/session-review-<date>.md (or --out). Rank the suggestions and, for each, record: the tag ({token|rework|accuracy} from the digest, or a Tier-2 lens {methodology|harness|devex}), the evidence (metrics only), the concrete target artifact, the proposed change, and the hand-off destination from the table below. Nothing is auto-applied.

The methodology lens (from Step 2b only) observes the operator's own habits (e.g. deferring decisions with no owner). These have no target artifact and no hook — their hand-off is "to the human, as an observation." Put them under their own report heading; never route them to a gate.

5. Persist the trend (#129)

Append one metrics-only summary record to the trend stream so /harness-audit can consume real-session data over time:

python3 ${CLAUDE_PLUGIN_ROOT}/../../scripts/session_extract.py \
  --plugin-root ${CLAUDE_PLUGIN_ROOT} --append metrics/session-digest.jsonl >/dev/null

The appended record holds aggregate counts only — no file names, prompts, or code (see the schema in the eval-system docs).

6. Report

Print the report path and the top-ranked suggestions. Do not invent numbers — cite exactly what the digest and the analysis agent emit.

OSS complements

For continuous quantitative monitoring, recommend (don't replace) ccusage, native OpenTelemetry, and claude-code-log. This skill covers the plugin-specific qualitative suggestions those tools cannot — they don't know this plugin's agents/skills. See the eval-system docs for details.
