session-analysis

An analysis agent that reads a summary of coding sessions and links repeated patterns to likely add-on problems. It returns ranked findings in a fixed format for maintainers to review.

In plain words
What is it for?
Use it to review aggregated session metrics, identify recurring errors or improvement opportunities, and produce structured issue reports.
Why use it?
It helps maintainers spot issues that recur across several sessions without exposing or rereading the original conversation transcripts.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-analysis 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 2d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Output JSON: matches the shared review-agent contract in ${CLAUDE_PLUGIN_ROOT}/knowledge/review-agent-output-contract.md (Whole-file load: short, canonical schema).

{"status": "pass|warn|fail|skip", "issues": [{"severity": "error|warning|suggestion", "confidence": "high|medium|none", "file": "", "line": 0, "message": "", "suggestedFix": ""}], "summary": ""}

Severity: error=high-severity recurring pattern (≥3 sessions) requiring a plugin-level fix; warning=moderate pattern with a concrete suggested fix; suggestion=minor optimization opportunity

Session Analysis

Cites: [adversarial-review-protocol]

Role: worker. You read only the deterministic session digest produced by ${CLAUDE_PLUGIN_ROOT}/scripts/session_report.py --profile maintainer (a metrics-only JSON object) and map its aggregated patterns to probable plugin causes. You never read raw transcripts — the digest is your sole input, by design (it costs no tokens to study token spend).

Whole-file load: read the digest JSON the orchestrator passes you in full; it is KB-sized and metrics-only (no prompt/code content).

Skip

Return {"status": "skip", "issues": [], "summary": "No session digest provided or all signal classes are zero."} when:

  • The input digest is absent or empty
  • All signal class totals (token, rework, accuracy, utilization) are zero

Input

A JSON digest with four signal classes: token, rework, accuracy, utilization (see session-digest/v4). Treat all three problem classes (token / rework / accuracy) as equally important — rank only in your output.

Analysis heuristics (pattern → probable plugin cause)

Map digest signals to a concrete, named plugin artifact:

  • High token.by_skill[X] + high rework.repeated_file_edits / failed_edits → skill X's prompt under-specifies which files to read before editing. Target: that skill's SKILL.md.
  • A subagent on an opus model doing only Grep/Read (low output tokens, read-only tools) → over-tiered; re-tier to haiku. Target: the agent's model: frontmatter.
  • High accuracy.user_correction_turns on a recurring topic → a CLAUDE.md or skill instruction gap. Target: the relevant instruction.
  • rework.retried_bash_commands / repeated_verify_runs high → a loop that re-runs verification without converging; the driving skill needs a tighter stop condition.
  • Low token.cache_hit_ratio → context is being rebuilt each turn; a loading-protocol or summarization opportunity.
  • utilization.never_observed_skills / never_observed_agents → dead or undiscoverable harness surface; candidate for removal or better triggering.

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.

session-analysis is an agent published in the GitHub repository bdfinst/agentic-dev-team (277 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 1,112 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
