060-evolve

A learning-management skill for extracting reusable patterns from past sessions and storing or reviewing them when persistence is enabled.

In plain words
What is it for?
Use it to analyze session history, review saved learnings, or choose which new patterns should be stored.
Why use it?
It helps preserve useful lessons between sessions instead of leaving them only in temporary conversation history.

Made for: Cursor.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,944 The whole file, excluding the scripts and references it only reads on demand.

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

060-evolve 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.

Evolve — Session Learning Extraction

Extract patterns from session history into reusable learnings. Three modes of operation.

Prerequisites

  • Persistence gate: persistence: true must be set in Session Config. If not, abort: "Learnings require persistence to be enabled in Session Config."
  • Session history must exist at .orchestrator/metrics/sessions.jsonl
  • Learnings are stored at .orchestrator/metrics/learnings.jsonl
  • Config field: learning-expiry-days (default: 30) — controls expires_at for new and updated learnings

Cursor Adaptation

No AskUserQuestion tool on Cursor. Present all choices as numbered Markdown lists:

Which learnings should be saved?

1. [fragile-file] src/lib/auth.ts — Changed in 4 of last 5 sessions (confidence: 0.5 new)
2. [scope-guidance] optimal-scope-per-session-type — 3 issues/session works well (+0.15 update)
3. Skip all — do not save any learnings

Reply with the number(s) of your choice.

Mode Selection

Determine mode from user input (default: analyze):

Mode Purpose
analyze Extract new learnings from session history
review Edit/manage existing learnings interactively
list Display active learnings (read-only)

Mode 1: Analyze

Extract learnings from .orchestrator/metrics/sessions.jsonl.

Step 1: Load Session Data

  1. Read all entries from sessions.jsonl, parse each line as JSON
  2. Sort by completed_at descending (most recent first)
  3. If no sessions found, abort: "No session data available."

Step 2: Pattern Extraction

Apply these heuristics for each learning type:

fragile-file
  • Same file appears in 3+ waves' files_changed within a session, or in 3+ different sessions
  • Subject = relative file path
effective-sizing
  • Compare total_agents and total_waves across session types
  • Calculate average agents per wave per session type
  • Subject = e.g. deep-session-sizing or feature-session-sizing
recurring-issue
  • agent_summary shows failed or partial > 0 across multiple sessions
  • Repeated failures in wave quality fields
  • Subject = issue pattern identifier (e.g. test-failures-in-wave-execution)

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.

060-evolve is a cursor rule published in the GitHub repository Kanevry/session-orchestrator (49 stars, last pushed 4d ago), licensed MIT. It adds 20 tokens to every session and 1,944 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.
