v0.2.1

A small patch release.

Fixed

• prescale mcp without the optional extra printed the wrong install command (pip install 'prescale' instead of 'prescale[mcp]') — rich was interpreting [mcp] as console markup. It now prints the correct command, with a regression test.

Docs

• Rewrote the README and refreshed the PyPI description for the full 0.2.x toolkit: load test → confidence band → investigate → MCP server → regression/CI → launch profiles.

Install: pip install prescale (add [mcp] for the agent server).

Full Changelog: v0.2.0...v0.2.1

v0.2.0

PreScale grew from a single load-test command into a full toolkit.

Added

• Saved runs & a versioned result contract — every run is stored under .prescale/runs/; prescale history / show re-open them, prescale schema documents the format. run --json and the saved file share one shape.
• A trustworthy verdict — a deterministic confidence band ("survives ~90 (80–110)") with a stable/uncertain flag, at no extra cost. Warmup runs by default (--no-warmup), plus --repeat N and --think-time S.
• prescale investigate — finds the route that breaks first, then probes it to diagnose why (a bottleneck class with confidence + evidence) and prescribe a fix. Fully local, no LLM.
• MCP server (prescale mcp) — load-test from a coding agent (Claude Code, Cursor). pip install 'prescale[mcp]'. Safe by default — local hosts only unless allowlisted.
• Regression + CI — --fail-under N, prescale compare (capacity diff of two runs), and --fail-on-regression (band-aware), plus a copy-paste GitHub Actions workflow.
• Launch profiles — prescale run --profile product-hunt frames the verdict as "would survive a Product Hunt #1 launch".

Changed

• --json now emits the full versioned Result and is robust to long lines.

Install: pip install prescale (add [mcp] for the agent server).
