pm-learn

pm-learn is a command for Claude Code from VandanaAjayDubey111/great-pm. It costs 52 tokens per session (853 once invoked), scanned A, original, MIT.

A session-learning command that finds repeated patterns, decisions, and unusual costs, then records them in project notes. Patterns seen at least three times can be promoted to shared decisions.

In plain words
What is it for?
Use it to capture recurring ways of working, important decisions, and cost outliers from the current session. It writes lessons to project files and can update shared decision notes.
Why use it?
It prevents useful lessons from being lost when a coding session ends. A dry-run option lets you review the proposed notes before they are saved.

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

pm-learn 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 18d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the great-pm /pm-learn command. Capture session learnings without requiring a full /pm-save.

Parse arguments

  • --dry-run → continuous-learner produces the lessons block but does NOT write it to disk. Print preview only.
  • (no flag) → write to .great-pm/lessons.md and promote ≥3-occurrence patterns to ~/.great-pm/decisions.md.

Pre-flight

echo "cwd=$(pwd)"
mkdir -p .great-pm
ls .great-pm/lessons.md 2>/dev/null && echo "LESSONS_OK" || echo "FIRST_RUN"
ls .great-pm/.learn-pending 2>/dev/null && echo "PENDING_MARKER" || echo "NO_MARKER"

If PENDING_MARKER exists → this is the recommended path (SessionEnd hook flagged something worth capturing).

Operating procedure

  1. Step 0 — refine the user's query (transparent Mode B). Invoke query-refiner-pm with $ARGUMENTS. The refiner returns:

    You typed:  <original>
    
    Refined to: <refined brief>
    
    What changed: <one line>
    
    Proceeding with refined. Reply "use original" to override.
    

    Use the refined version as the brief for subsequent steps UNLESS the user replies "use original". Log the refinement to .great-pm/refinements/$(date +%Y-%m-%d).log. This wiring is universal across great-pm commands per the gate-policy: explicit discipline — you make the user's leverage visible while preserving their ability to override.

  2. Spawn continuous-learner as a subagent with:

    • Mode: auto-extract (no manual prompt).
    • Read the session history available to you.
    • --dry-run flag if set.
  3. The agent identifies:

    • Repeatable patterns (≥2 occurrences in this session).
    • Decisions worth promoting (architectural, governance, naming).
    • Cost outliers (long-running agent invocations, repeated tool failures).
  4. Output format (appended to .great-pm/lessons.md):

    ## <YYYY-MM-DD HH:MM> session
    - pattern: <one-line>  (count: N)
    - decision: <one-line>  (rationale: <one-line>)
    - cost outlier: <one-line>

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.

pm-learn is a command published in the GitHub repository VandanaAjayDubey111/great-pm (3 stars, last pushed 18d ago), licensed MIT. It adds 52 tokens to every session and 853 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-21.
