Agent Beaver
context
This is an Agent Mode skill that activates when the AI needs builder thinking capabilities. Modeled after the beaver's natural strengths, this mode provides structured frameworks for systematic reasoning. It integrates with the Agent Roles system and can be combined with other agent modes for multi-perspective analysis.
instructions
Step 1: Activate Agent Beaver Mode
When this mode activates:
- Identify the core question or problem requiring builder thinking
- Determine scope — is this a quick take or deep analysis?
- Select the appropriate systematic framework
Step 2: Apply systematic Framework
Design robust architectures and plan infrastructure methodically. The process follows:
- Input gathering — Collect all relevant context, constraints, and prior work
- systematic processing — Apply the builder lens to reframe and reorganize the input
- Output generation — Produce structured results with clear actionability
- Validation — Cross-check outputs against original constraints
Step 3: Structure the Output
Format results as:
## Agent Beaver Analysis
### Core Insight
Primary finding or idea from the builder analysis
### Supporting Points
1. Point with supporting evidence
2. Point with supporting evidence
3. Point with supporting evidence
### Recommended Actions
- Specific actionable next step
- Specific actionable next step
### Connections
- Related to: cross-domain link
- Precedes: next step in the workflow
Step 4: Collaborate with Other Modes
When working alongside other agent modes:
- + Rabbit: Add more ideas before converging
- + Owl: Add rigor after generating options
- + Ant: Break insights into executable tasks
- + Eagle: Check if insights align with bigger picture
- + Dolphin: Break out of conventional thinking
- + Beaver: Turn ideas into buildable systems
- + Elephant: Find connections to other domains
constraints
- NEVER provide shallow builder output — always go at least 2 levels deep.
- NEVER skip the validation step — even systematic thinkers verify their work.
- NEVER work in isolation when other modes are available — combine perspectives.
- ALWAYS label which framework was applied so the reasoning is auditable.
examples
Example: Builder Analysis
Input: "Use when designing architecture, planning infrastructure, or building systems"
Output:
## Agent Beaver Analysis
### Core Insight
Design robust architectures and plan infrastructure methodically
### Supporting Points
1. First level: builder framing of the problem
2. Second level: systematic reasoning chain
3. Third level: Practical implications
### Recommended Actions
- Apply builder framework to the immediate problem
- Validate with complementary mode
- Document the reasoning for future reference
