What you end up with
You see what a finished task costs before you try to cut anything.
What you get
- The formula
- The usage sheet
- Three rules
- A check prompt
Who it is for
Anyone who wants to know what their coding agent really costs per job.
Works with
Solid chips: the agent is named in this listing's own tools list. Dashed chip: Plain Markdown, so it also pastes into other agents such as Grok Bot, Hermes, OpenClaw or Muse. We list those as compatible by format only, not as tested.
Tools needed
Cost to run: Free.
Time to result: Fifteen minutes
Sample prompts, free to use
Here are the baseline and the new run for the same ten tasks [paste both]. Compute cost per solved task and the pass count for each, and the change. If the pass count dropped, say so first. Do not call anything a saving if quality fell.
Run it after every lever you try.

# Cost per solved task: the one-sheet agent cost check (free sample) A free sample from Agent Cost Levers by PaperChaseWebb. Works with Claude Code, Codex, Cursor or any agent tool that reports usage. Most agent cost advice starts with the model price. Start with what you control: how many tasks actually get done for the money. ## The number **cost per solved task = total spend on a batch / tasks that passed a check you wrote before the run** - A task is solved only when a check says so: a test, a script, a lint pass, a two-minute reviewer checklist. - Failed and abandoned runs stay in the total.
Worth knowing
- Measure on real tasks. Toy prompts give misleading numbers.

Agent Cost Levers: cut cost per solved task without cutting quality
A Markdown pack that measures what your coding agent spends per finished task, then works five levers one at a time: thinking depth, context curation, direct tool routing, cache and reuse, and a verified stop. Includes a baseline sheet, a rules block and 10 prompts.
Token saver: keep long command output out of your coding agent's context
Two shell scripts and one rule line that make Claude Code, Codex, Cursor and other agents read a one-page summary of builds, tests and searches instead of thousands of lines.
Spec-First Build Docs: PRD, design system, architecture note, agents guide and readiness check
A Markdown pack of the four documents to write before an agent builds anything, sized to the stakes: a PRD an agent can build from without inventing scope, the smallest design system that holds, a one-page architecture note with reversal costs, an agents guide with a project tree for Claude Code, Codex and Cursor, a weekly staleness pass and a nine-area readiness check.
