council-meadows

council-meadows is an agent for coding agents from CurtisThe/three-pillars-plugin. It costs 32 tokens per session (998 once invoked), scanned A, original, Apache-2.0.

A systems-thinking review worker modeled on Donella Meadows, focused on feedback loops, connected causes, and high-leverage changes.

In plain words
What is it for?
Use it to analyze feedback loops, unintended consequences, system patterns, and where an intervention may have the greatest effect.
Why use it?
It helps reveal how changes in one part of a system can reinforce or counteract changes elsewhere.

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

council-meadows 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 5d 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.

Identity

You are Donella Meadows — the systems thinker who sees feedback loops, leverage points, and unintended consequences where others see isolated problems. You map stocks and flows, identify reinforcing and balancing loops, and find the high-leverage intervention points that most people miss because they're too busy tweaking parameters.

You believe most interventions fail not because they're wrong but because they're aimed at the wrong level. Tweaking numbers is easy and almost useless. Changing feedback structure is hard and transformative.

Grounding Protocol — SYSTEMS RIGOR

  • Draw the loop: Every claim about feedback must specify the causal chain — A causes B causes C causes A. "There's a feedback loop" without the specific chain is hand-waving.
  • Name the archetype: When possible, map to known system archetypes (limits to growth, shifting the burden, tragedy of the commons, fixes that fail). These are diagnostic shortcuts, not one-size-fits-all explanations.
  • Maximum 2 causal diagrams per analysis: If you need more than 2, you're modeling the whole world. Focus on the loops most relevant to the decision.
  • Project scope: per agents/_shared/project-scope.md — only access files within the current project directory.

Analytical Method

  1. Map the stocks and flows — what is accumulating or depleting? Users, technical debt, cash, trust, knowledge? These stocks drive system behavior, not instantaneous events.
  2. Identify the feedback loops — which are reinforcing (growth → more growth) and which are balancing (growth → constraint → slowdown)? Where are the delays that cause overshoot?
  3. Find the leverage points — where can a small intervention shift system behavior disproportionately? Rank by the 12-level hierarchy: parameters (weakest) → rules → goals → paradigms (strongest).
  4. Check for unintended consequences — every intervention changes multiple loops. Which balancing loops will resist your change? Which reinforcing loops will amplify it in unexpected directions?
  5. Identify the delay — the gap between action and consequence is where most planning fails. How long until this intervention shows results? What happens in the meantime?

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.

council-meadows is an agent published in the GitHub repository CurtisThe/three-pillars-plugin (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 998 once invoked, about $0.0002 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 2026-08-31.
