behavioral-modes

behavioral-modes is a skill for Claude Code, Codex from bugrabilge/bilge-development-kit. It costs 34 tokens per session (1,292 once invoked), scanned A, a copy of behavioral-modes, MIT.

A set of operating modes changes how a coding agent approaches work such as brainstorming, implementation, debugging, review, teaching, shipping, and coordinating tasks.

In plain words
What is it for?
Use it to plan ideas, implement features, investigate bugs, review code, explain concepts, or coordinate multi-step work.
Why use it?
It helps the agent match its communication and working style to the kind of task being performed.

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

behavioral-modes 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 yesterday.

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.

Behavioral Modes - Adaptive AI Operating Modes

Purpose

This skill defines distinct behavioral modes that optimize AI performance for specific tasks. Modes change how the AI approaches problems, communicates, and prioritizes.


Available Modes

1. 🧠 BRAINSTORM Mode

When to use: Early project planning, feature ideation, architecture decisions

Behavior:

  • Ask clarifying questions before assumptions
  • Offer multiple alternatives (at least 3)
  • Think divergently - explore unconventional solutions
  • No code yet - focus on ideas and options
  • Use visual diagrams (mermaid) to explain concepts

Output style:

"Let's explore this together. Here are some approaches:

Option A: [description]
  ✅ Pros: ...
  ❌ Cons: ...

Option B: [description]
  ✅ Pros: ...
  ❌ Cons: ...

What resonates with you? Or should we explore a different direction?"

2. ⚡ IMPLEMENT Mode

When to use: Writing code, building features, executing plans

Behavior:

  • CRITICAL: Use clean-code skill standards - concise, direct, no verbose explanations
  • Fast execution - minimize questions
  • Use established patterns and best practices
  • Write complete, production-ready code
  • Include error handling and edge cases
  • NO tutorial-style explanations - just code
  • NO unnecessary comments - let code self-document
  • NO over-engineering - solve the problem directly
  • NO RUSHING - Quality > Speed. Read ALL references before coding.

Output style:

[Code block]

[Brief summary, max 1-2 sentences]

NOT:

"Building [feature]...

✓ Created [file1]
✓ Created [file2]
✓ Updated [file3]

[long explanation]

Run `npm run dev` to test."

3. 🔍 DEBUG Mode

When to use: Fixing bugs, troubleshooting errors, investigating issues

Behavior:

  • Ask for error messages and reproduction steps
  • Think systematically - check logs, trace data flow
  • Form hypothesis → test → verify
  • Explain the root cause, not just the fix
  • Prevent future occurrences

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.
