synthesize-learnings

synthesize-learnings is a skill for Claude Code from richfrem/agent-plugins-skills. It costs 66 tokens per session (1,604 once invoked), scanned A, original, MIT.

A workflow that turns plugin analysis results into practical improvement recommendations. It maps findings to changes in scaffolding tools, standards, and related documentation.

In plain words
What is it for?
Use it after analyzing plugins to propose updates to agent-building tools, templates, acceptance criteria, and ecosystem guidance.
Why use it?
It closes the gap between discovering patterns or problems and deciding what to improve next.

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

synthesize-learnings 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 6d 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.

Synthesize Learnings

Take raw analysis output from analyze-plugin and transform it into concrete, actionable improvements for our meta-skills ecosystem. This is the "close the loop" skill that turns observations into evolution.

Improvement Targets

Learnings are mapped to three improvement targets:

Target 1: agent-scaffolders

Improvements to the plugin/skill/hook/sub-agent scaffolding tools.

What to look for:

  • New component types or patterns that scaffold.py should support
  • Better default templates based on exemplary plugins
  • New scaffolder skills needed (e.g., creating connectors, reference files)
  • Improved acceptance criteria templates based on real-world examples

Target 2: agent-scaffolders

Improvements to ecosystem standards and authoritative source documentation.

What to look for:

  • New best practices discovered from high-quality plugins
  • Anti-patterns that should be documented as warnings
  • Spec gaps where plugins do things the standards don't address
  • New pattern categories to add to ecosystem knowledge

Target 3: agent-scaffolders (Self-Improvement)

Improvements to this analyzer plugin itself.

What to look for:

  • New patterns discovered that should be added to pattern-catalog.md
  • Analysis blind spots — things that should have been caught
  • Framework gaps — phases that need refinement
  • New anti-patterns to add to the detection checklist

Target 4: Domain Plugins (e.g., oracle-legacy-system-analysis)

Improvements to the primary domain plugins in this repository — especially the legacy Oracle Forms/DB analysis plugins.

What to look for:

  • Severity/classification frameworks that could improve how legacy code issues are categorized (e.g., GREEN/YELLOW/RED deviation severity from legal contract-review)
  • Playbook-based review methodology adaptable to legacy code review playbooks (standard migration positions, acceptable risk levels)
  • Confidence scoring applicable to legacy code analysis certainty levels
  • Connector abstractions (~~category patterns) for tool-agnostic Oracle analysis workflows
  • Progressive disclosure structures for organizing deep Oracle Forms/DB reference knowledge
  • Decision tables for legacy migration pathways (like chart selection guides but for migration strategies)
  • Checklist patterns for legacy system audit completeness
  • Tiered execution strategies for handling different legacy code complexity levels
  • Bootstrap/iteration modes for incremental legacy system analysis
  • Output templates (HTML artifacts, structured reports) for presenting legacy analysis results

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.
