session-review

session-review is a skill for Claude Code from bdfinst/agentic-dev-team. It costs 59 tokens per session (3,699 once invoked), scanned A, original, MIT.

A tool that reads Claude Code session records and produces suggestions for improving an agent setup. It uses measured session data rather than asking the agent to inspect raw transcripts directly.

In plain words
What is it for?
Use it to review past Claude Code sessions, rank workflow problems, and decide which plugin, skill, or configuration changes may help.
Why use it?
It helps identify wasted tokens, repeated work, and accuracy problems while keeping changes under human control. The tool suggests improvements but does not apply them.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions subagents; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

session-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 .claude/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 3b — the raw-log semantic tier): 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: .dev-team-reports/session-review-<date>.md).
  • --cross-machine: opt into cross-machine telemetry sync + rollup (#1480). Absent by default — a plain /session-review analyzes only this machine's local digest. See Step 1.

Steps

Pre-flight — session_report.py ships; only cross-machine mode does not (#1779, closed by #2046/#2047)

Core extraction (Steps 0, 2, 3, 4, 5, 6 below) runs entirely from ${CLAUDE_PLUGIN_ROOT}/scripts/session_report.py --profile maintainer — a shipped script, present on every install, not only this monorepo's own dev checkout (until #2046/#2047, this ran the old repo-root extractor [ADR 0036 supersedes], deliberately monorepo-only tooling never shipped inside the plugin — see ADR 0032's Category 2 — which is why this section used to guard the whole skill on a dev-checkout check).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
