rudder-performance-architecture-maintainer

rudder-performance-architecture-maintainer is a skill for Claude Code, Codex from Undertone0809/rudder. It costs 60 tokens per session (3,052 once invoked), scanned A, original, Apache-2.0.

A guide for improving Rudder’s speed and software structure. Rudder is evaluated through issues such as slow pages, repeated data loading, large responses, and costly database or API work.

In plain words
What is it for?
Use it to investigate slow pages, cache misses, repeated requests, large-organization data loading, expensive API or database paths, and unclear code boundaries.
Why use it?
It directs the agent to measure problems and preserve existing product behavior instead of making untested performance changes.

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

rudder-performance-architecture-maintainer 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 12d 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.

Rudder Performance Architecture Maintainer

Use this skill when the user wants Rudder to become faster, more stable, or cleaner at the architecture boundary. The default result should be evidence-led optimization that preserves product contracts, not speculative tuning.

This skill covers two related classes of work:

  • performance fixes: cache behavior, network waterfalls, repeated skeletons, slow queries, refetch loops, expensive renders, build/test slowness
  • architecture fixes: unstable boundaries, oversized modules, duplicated data paths, unclear ownership, abstractions that make performance hard to reason about

Read references/optimization-checklist.md before doing non-trivial work with this skill. When the user asks for broad optimization or know-how capture, also read references/recent-thread-signals.md.

Use When

Use this skill for requests like:

  • "为什么 dashboard 每次都骨架屏"
  • "全局看看哪里可以做缓存加速"
  • "这个页面/API 太慢,找一下瓶颈"
  • "做一版系统性能优化"
  • "数据量一大之后网页卡,给我优化前后的具体数值"
  • "用 ZStudio 同等规模的数据在 DEV 里测一下"
  • "这里是不是 query key / staleTime / invalidation 写错了"
  • "架构上有什么热点文件或边界可以优化"
  • "把这次性能优化 know how 沉淀成 skill"
  • "分析一下最近的 thread 里有没有类似性能/架构任务"

Do Not Use When

Do not use this skill when the primary task is:

  • data exists but a page shows missing, stale, sparse, or wrong data; use rudder-data-path-diagnostician-maintainer
  • a large refactor where the user explicitly wants plan plus execution as the main deliverable; use architecture-refactor-driver-maintainer
  • pure UI polish, spacing, copy, or visual QA
  • release, package, installer, or Desktop startup recovery
  • a single agent transcript or runtime failure investigation

If the task overlaps, choose the skill that matches the user's visible pain. For example, repeated skeleton loading after navigation belongs here; empty dashboard data belongs to data-path diagnosis.

Inputs

Capture or infer:

  • affected surface, route, API, service, or subsystem
  • user-visible symptom and expected improvement
  • runtime and organization when live data is involved
  • current cache, invalidation, polling, and freshness expectations
  • constraints that must remain stable: API shape, schema, org scoping, runtime contracts, UI behavior
  • acceptable validation depth for the blast radius

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.
