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 | $0.00035 | $0.00820 |
| Opus 5 | $0.00017 | $0.00410 |
| Sonnet 5 | $0.00007 | $0.00164 |
| Haiku 4.5 | $0.00003 | $0.00082 |
Grade A, and why
competitive-agents 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 2d 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.

Competitive Agents
Overview
Dispatch two independent subagents to solve the same task from different angles. The main agent then synthesizes the best elements into a superior combined result.
When to Use
- Designing systems, architectures, or APIs
- Problems with multiple valid approaches (no single obvious answer)
- User explicitly requests competitive/parallel approaches
- You want to reduce single-agent bias
When NOT to Use
- Purely mechanical tasks (rename variable, fix typo, add import)
- Tasks requiring sequential steps (not parallelizable)
- Task is unclear — clarify with user first, then decide
Red Flags - Skill Still Applies
Don't skip just because:
- Task seems "simple" (simplicity ≠ obvious solution)
- You think one approach is "best" (that's exactly the bias to avoid)
If multiple valid approaches exist, use this skill.
Workflow
- Clarify if needed — if the task is ambiguous, ask the user before dispatching
- Dispatch 2 subagents in parallel (single message, 2 Task tool calls)
- Wait for both results
- You (main agent) synthesize the best elements directly — no third subagent
- Present synthesized result to user
Competitor Prompt Template
Each competitor gets the same task but a different constraint to force divergent solutions:
Competitor A:
You are competing against another agent to solve the same task.
The better solution will be selected. Give your absolute best effort.
YOUR CONSTRAINT: Prioritize simplicity and minimalism. Fewer moving parts wins.
## Task
{task content from user}
## Requirements
- Provide a complete, well-reasoned solution
- Explain your approach and key decisions
- Consider trade-offs and alternatives you rejected
Competitor B:
You are competing against another agent to solve the same task.
The better solution will be selected. Give your absolute best effort.
YOUR CONSTRAINT: Prioritize completeness and extensibility. Cover more cases and future needs.
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.

competitive-agents is a skill published in the GitHub repository baleen37/bstack (4 stars, last pushed 12d ago), licensed MIT. It adds 35 tokens to every session and 820 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.

agent-messaging
Send and receive cryptographically signed messages between AI agents using the Agent Messaging Protocol (AMP). Use when the user asks to "send a message to an agent", "check agent inbox", "message another agent", "reply to a message", "notify an agent", or any inter-agent communication task.
workflows
Execute a workflow script that orchestrates multiple subagents deterministically. Use when the user explicitly requests a workflow, multi-agent orchestration, parallel or sequential agent pipelines, structured agent outputs, or a durable background workflow run.
