Cut per-request context overhead
“Artifact alone is about 11.4k tokens: in our sessions it is the largest single block of the first call's context after the system prompt.”
What gets counted gets built. Pile on.
Paste this into your agent. It files your request, with what you need it for.
I want this: rapsheet.dev/sheets/claude-code/themes/277/file Follow it to file my request. Show me the text before you send.
No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

- Subagents with minimal startup context5 people
- Chain tool steps without round trips4 people
What's included
- When a session or subagent sends requests, fixed or repeated context it does not need takes up tokens and room today, and people want each request to carry only what the work needs so they save tokens and avoid compaction.
- Subagents dispatched for small tasks start with the parent's full context, tool schemas, CLAUDE.md, sandbox rules and git status.
- Built-in tool schemas a session never calls are sent inline on every request.
- Chains of data-dependent tool steps re-read the whole context once per hop.
Not included
- Capping spend per session or task so an unattended run pauses before it overruns.
- Seeing how session cost splits across the models used.
- Reducing what a single tool result adds to context.
