Standardized cost-estimation framework for great-pm initiatives. Forces explicit LLM cost (across great-pm pipelines), human-equivalent comparison, infra delta, and time-to-ship. Output is parsable by /pm-burn and /pm-cost. great-pm version covers PM-side cost.
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 model — make great-pm cost claims defensible great-pm reports cost numbers on the board (via /pm-cost, /pm-burn, /pm-digest). Those numbers MUST be auditable. The classic mistake: a shiny "1000× human equivalent" claim that doesn't survive scrutiny. This skill defines the format and the discipline. ## The 4-line cost section Every great-pm initiative's cost section follows this exact template: ```markdown ## Cost estimate **LLM**: $<low>–<high> (<N> agent invocations × $<per-call avg>) **Human equiv**: $<low>–<high> (<hours> × $<rate>/h) **Infra delta**: $<low>–<high>/month **Time to ship**: <hours> agent-time, <hours/days> wall-clock > Methodology: <one-sentence rationale for each range> ``` ### Why this exact format? Board parsers anchor on **line-start** "LLM" and "Human" labels. Mid-line references are ignored. Stick to the template — drift breaks the board. ## How to estimate each line ### LLM cost For each great-pm agent that runs in the initiative, estimate: - **Prompt tokens** = system prompt + injected context (PROJECT.md + brain.md tail + HANDOFF.md, per SubagentStart hook) + agent-specific input …

How to install
mdr add vandanaajaydubey111/great-pm/cost-model@sha256:754df6362c246a91The line at the top of this page pins the label git:20260721.86de099, 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.
