capacity-planner is a skill for Codex from bestagentkits/agency-skills. It costs 166 tokens per session (3,140 once invoked), scanned A, a copy of capacity-planner, MIT.

A staffing and workload planning tool for teams that handle queued work, such as support, customer success, IT operations, or finance operations. It uses demand, utilization, service-level risk, hiring, and attrition inputs.

In plain words
What is it for?
Use it for annual capacity plans, utilization checks, quarterly hiring plans, and staffing coverage decisions.
Why use it?
It helps estimate how many people are needed at normal and peak demand, and shows when high workload could cause delays or overload.

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-planner 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/capacity_modeler.py, scripts/hiring_sequencer.py, scripts/utilization_analyzer.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.

capacity-planner

Sizing tool for ops teams that handle queued work — Support, CX, Customer Success, BizOps, IT ops, Finance ops. Built on Erlang-C queueing theory, Little's Law, and the operational-leadership canon (Fournier, Larson, Cleveland, Reinertsen). Deterministic, stdlib-only, no LLM calls.

Purpose

You are an ops leader sized 15 → 35 with no idea how the 35-person org will actually behave at peak load. Or you are at 88% utilization and SLA is starting to slip. Or you have a hiring budget approved and need to sequence it across four quarters without burning out the existing team. This skill answers those questions with arithmetic, not vibes.

It produces three artifacts:

  1. Capacity sizing at 70/80/90% utilization against P50/P90/P99 demand, with P(SLA breach) at each point and a SAFE/WATCH/AT_RISK/CRITICAL risk band.
  2. Utilization health at the per-member traffic-light level plus a team verdict (HEALTHY/SQUEEZED/OVERLOADED/UNBALANCED).
  3. 12-month quarterly hiring plan accounting for ramp curves, attrition, QoQ demand growth, and span-of-control manager triggers.

When to use

  • Annual ops capacity planning (October-November for the following fiscal year).
  • Quarterly re-sizing if demand changed >15% or attrition spiked.
  • Pre-budget defense — the math that justifies the headcount ask to your CFO.
  • Diagnostic when an ops team is missing SLA and you need to know whether it's a sizing problem, a process problem, or a bottleneck problem.
  • M&A / new-segment launch modeling — sizing a new team or combined org.

Workflow

  1. Intake demand. Pull P50/P90/P99 daily ticket/case volume from your work system (Zendesk, Intercom, JSM, ServiceNow, Salesforce). If you only have averages, stop and pull the distribution. Single- point demand estimates are the most expensive anti-pattern in ops.
  2. Model throughput. Run capacity_modeler.py with your demand, AHT, SLA target, current FTE, and shrinkage. Use --profile for your function (support / cx / bizops / finance-ops / it-ops). Read the 80%-utilization row — that's your sizing point.
  3. Flag utilization risk. Run utilization_analyzer.py against your current team's actual utilization data. Anyone >85% sustained is a throughput-collapse risk per Reinertsen. Spread >30 percentage points across team means UNBALANCED — fix that before hiring.
  4. Sequence hiring. Run hiring_sequencer.py with current FTE, target EOY, ramp time, attrition, and growth. It will front-load hires (Q1 35%, Q4 15%), apply ramp curves, and trigger a manager hire when span of control crosses 7 ICs/manager.
  5. Walk the Forcing-question library (see below). One question at a time. Do not skip ahead. Answers must be written down before you commit the plan.

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.
