accelerate

A guide for making an AI workflow faster, less expensive, or both while measuring its results before and after changes. It considers response time, cost, token use, and errors.

In plain words
What is it for?
Auditing latency and token usage, shortening prompts, using structured output, routing simpler requests to cheaper models, escalating harder requests, and caching repeated work.
Why use it?
It helps identify what is causing slow or expensive operation before applying optimisations, while checking that quality does not decline.

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.

Security

Grade A, and why

accelerate 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.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY PREPARATION

Invoke /agent-workflow — it contains workflow principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no workflow context exists yet, you MUST run /teach-maestro first. Consult the context-management reference in the agent-workflow skill for window optimization and budget strategies.


Make the workflow faster and cheaper without sacrificing quality. Measure before and after.

Performance Audit

Measure current performance:

Current metrics:
  Latency (p50): ___ms
  Latency (p95): ___ms
  Cost per request: $___
  Token usage (avg): ___ input / ___ output
  Error rate: ___%

Acceleration Strategies

Reduce Token Usage

  • Shorten system prompts (remove redundant instructions)
  • Compress few-shot examples to minimum viable length
  • Use structured output schemas instead of verbose text
  • Summarize context instead of passing raw documents
  • Reduce output length requirements

Model Cascading

  • Route simple tasks to cheaper/faster models
  • Escalate only complex tasks to capable models
  • Use classification to determine complexity

Caching

  • Cache responses for identical or near-identical inputs
  • Cache tool results with appropriate TTL
  • Cache embeddings for frequently-queried documents
  • Use semantic caching for similar (not identical) queries

Parallelization

  • Run independent tool calls in parallel
  • Run independent agent steps in parallel
  • Use streaming to start processing before full response

Context Optimization

  • Retrieve less, retrieve better (improve retrieval precision)
  • Use context compression techniques
  • Implement sliding window for long conversations

Acceleration Report

For each optimization:

  1. What changed: Specific modification
  2. Before: Latency/cost/tokens before
  3. After: Latency/cost/tokens after
  4. Quality impact: Any quality change (verify with golden tests)
  5. Trade-off: What was sacrificed for the improvement

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.

accelerate is a skill published in the GitHub repository sharpdeveye/maestro (415 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 629 once invoked, about $0.0001 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 2026-08-30.
