Getting it into your agent
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00754 |
| Opus 5 | $0.00021 | $0.00377 |
| Sonnet 5 | $0.00008 | $0.00151 |
| Haiku 4.5 | $0.00004 | $0.00075 |
Grade A, and why
systems-thinking 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 8d 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.
This is a copy
100% identical to systems-thinking — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Systems Thinking
Help the user apply systems thinking to complex problems using frameworks and insights from 6 product leaders.
How to Help
When the user asks for help with systems thinking:
- Map the system - Help them identify all players, their incentives, and how they interact with each other
- Identify stocks and flows - Understand what accumulates (stocks) and what moves between states (flows)
- Trace second-order effects - Work through what happens after the first-order impact of any change
- Find leverage points - Identify where small interventions can create large systemic changes
Core Principles
See the system
Seth Godin: "What does it mean to be a strategic thinker? It means to see the system." Understanding the invisible rules, culture, and interoperability that govern how products and organizations succeed or fail is the foundation of strategic thinking.
Think about all players and incentives
Sriram: "Systems thinking. Think of all the players in the system, think of all of their incentives and how they interact with each other." This approach is superior to Jobs-to-be-Done for handling complex product trade-offs and multi-agent incentives.
Use stocks and flows
Will Larson: "Systems thinking is basically you try to think about stocks and flows. Stocks are things that accumulate and flows are the movement from a stock to another thing." Model business processes like hiring pipelines or user funnels using this framework.
Consider second, third, and fourth-order effects
Hari Srinivasan: "The skillsets that you think through and manage in a complicated ecosystem are quite different." Managing complex ecosystems requires understanding effects that cascade beyond the immediate impact.
Think beyond today's decisions
Nickey Skarstad: "Second order thinking is you being able to think beyond the decisions that you're making today." Consider how current decisions impact future constraints and ecosystem dynamics.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

systems-thinking is a skill published in the GitHub repository martineserios/thebrana (3 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 754 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to systems-thinking, differing in 0 lines, and is treated as a copy.
