capacity-resource-estimation

capacity-resource-estimation is a skill for Claude Code from jeet129/praxis. It costs 119 tokens per session (3,222 once invoked), scanned A, original, MIT.

An infrastructure sizing method that turns expected usage and performance targets into compute, memory, storage, network, and scaling requirements for each service.

In plain words
What is it for?
Use it before deployment, after load testing, or when planning a traffic surge. It helps define resource limits, autoscaling rules, growth assumptions, and disaster-recovery capacity.
Why use it?
It prevents teams from guessing how much infrastructure they need or discovering too late that a service cannot handle growth. It also makes capacity costs and trade-offs explicit.

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

capacity-resource-estimation 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 8d 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.

Capacity & Resource Estimation

capability: build-and-deploy
domain: infra
state: active
dependencies:
  - nfr-definition
  - architecture-pattern-selection
  - iac
triggers:
  - "sizing infrastructure for a new project"
  - "sizing a new service before initial deploy"
  - "revisiting capacity after load data invalidates initial assumptions"
  - "preparing the production_go_live evidence package"
  - "growth-event planning (campaign, expansion, expected surge)"
outputs:
  - sizing model per service (compute / memory / storage / IOPS / network)
  - autoscaling policy (min / max / triggers)
  - capacity assumptions (workload model, dependency calls, growth curve)
  - headroom buffer per service
  - environment cost envelope (monthly $)
  - cost-vs-NFR tradeoff documentation
consumers:
  - platform-sre (primary author)
  - iac (consumes sizing for resource definitions)
  - deploy-release (consumes for pod/container resource requests + limits)
  - cost-finops (consumes for budgets and attribution)
  - performance-testing (load test scenarios match the sizing assumptions)
  - reliability-dr (DR sizing follows from this)
references: []

The discipline that turns NFR targets into provisioned infrastructure. Without it, projects either over-provision (paying for idle capacity) or under-provision (paging at peak load). With it, sizing is evidenced — explicit workload model, explicit assumptions, explicit growth curve — so revisions are honest and reproducible.

Capacity sizing isn't an exact science but it should be visibly approximate — when sizes are wrong, the assumptions that drove them should be visible enough to revise.

When this skill fires

  • A new project's infrastructure is being sized for the first time.
  • A new service is being added; its size needs estimation before initial deploy.
  • Mid-project, load data reveals the initial sizing assumptions were wrong; resize.
  • The production_go_live gate needs evidence of capacity sufficiency.
  • A growth event is being planned (marketing campaign, geographic expansion, expected surge).

capacity-resource-estimation is a skill published in the GitHub repository jeet129/praxis (7 stars, last pushed 4d ago), licensed MIT. It adds 119 tokens to every session and 3,222 once invoked, about $0.0006 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.
