What is performance-bottlenecks?

A performance-analysis feature that looks for delays and inefficient patterns in development tasks handled by agents. It examines execution time, agent use, resources, and operations.

Use it to inspect completed task results, identify time, coordination, or resource bottlenecks, and review suggested improvements such as parallel execution or additional specialized agents.

It highlights problems such as work being done sequentially when it could run in parallel, unbalanced agent workloads, excessive operations, or limited memory and input/output capacity.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00310
Opus 5.5	$0.00000	$0.00124
Sonnet 5.5	$0.00000	$0.00062

Security

Grade A, and why

performance-bottlenecks 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 1mo 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.

Origin

This is a copy

100% identical to performance-bottlenecks — 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.

What it actually says

Performance Bottleneck Analysis

Purpose

Identify and resolve performance bottlenecks in your development workflow.

Automated Analysis

1. Real-time Detection

The post-task hook automatically analyzes:

Execution time vs. complexity
Agent utilization rates
Resource constraints
Operation patterns

2. Common Bottlenecks

Time Bottlenecks:

Tasks taking > 5 minutes
Sequential operations that could parallelize
Redundant file operations

Coordination Bottlenecks:

Single agent for complex tasks
Unbalanced agent workloads
Poor topology selection

Resource Bottlenecks:

High operation count (> 100)
Memory constraints
I/O limitations

3. Improvement Suggestions

Tool: mcp__claude-flow__task_results
Parameters: {"taskId": "task-123", "format": "detailed"}

Result includes:
{
  "bottlenecks": [
    {
      "type": "coordination",
      "severity": "high",
      "description": "Single agent used for complex task",
      "recommendation": "Spawn specialized agents for parallel work"
    }
  ],
  "improvements": [
    {
      "area": "execution_time",
      "suggestion": "Use parallel task execution",
      "expectedImprovement": "30-50% time reduction"
    }
  ]
}

Continuous Optimization

The system learns from each task to prevent future bottlenecks!

Changes

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.

performance-bottlenecks is a command published in the GitHub repository f-amine/vibe-stack (21 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 310 tokens. A static security scan graded it A with 0 findings. It is 100% identical to performance-bottlenecks, differing in 0 lines, and is treated as a copy.
