Use when the user wants to estimate or predict the cost, token usage, or time of a task BEFORE it runs — "how much will this feature cost to build", "estimate the tokens for this spec", "what will this slice cost", "predict the agent-compute time before I commit" — produces a token + time estimate as a range with disclosed confidence, adding a dollar figure only when an observability/costs snapshot grounds it. The prospective sibling of cost-tracking, which records actual spend after the fact.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cost Estimation Estimate, *before* work runs, the token usage and time a task will consume flowing through the orchestrator pipeline — and a dollar cost **only when observed actuals exist to ground it**. This is the **prospective** counterpart to the **retrospective** `cost-tracking` skill. `cost-tracking` *records* what was spent into `observability/costs/YYYY-MM-DD-costs.md`; this skill *reads* those same snapshots as its $/token ground and *predicts* what a task will spend. The two are siblings — a reader who finds one should find the other (see [Sibling relationship](#sibling-relationship-to-cost-tracking)). The day-one deliverable is a **token + time estimate**. Both axes are fully groundable from `MODEL_ROUTING.md` today, so they are the honest first-version value of this capability. The dollar figure is an **actuals-gated enhancement** — present and grounded only when an `observability/costs/` snapshot supplies a usable $/token rate, otherwise omitted with an explicit disclosure (never a forced list-price guess). This skill is **methodology and a format contract**. It describes how an estimate is derived and what an estimate record must contain. It does not …

How to install
mdr add habitat-thinking/ai-literacy-superpowers/cost-estimation@sha256:7dbd433125e5fac7The line at the top of this page pins the label git:20260615.89f6ae8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
