What Session Optimizer does

Cross-platform prompt refinement for Codex, Gemini CLI, and Claude Code, plus Claude-native context guard and telemetry statusline plugins. Portable refine-gate binds vague prompts to evidence; optional hooks enforce checkpoints, track subagent spend, and surface context and quota telemetry.

**Cross-platform prompt refinement for Codex, Gemini CLI, and Claude Code, plus context-budget and telemetry controls.** The portable `refine-gate` skill binds vague requests to concrete evidence on all three hosts. `context-guard` enforces a per-model context-budget checkpoint on both Claude Code and Codex (each host's own Stop-hook contract). `statusline` adds passive telemetry where Claude Code exposes the required metrics.

The repository ships three small, dependency-light, **independently installable** packages. Install exactly the ones your host supports and you need; none requires the others.

/plugin marketplace add cdeust/session-optimizer

Plugin	One-line install	What it does
context-guard	Claude: `/plugin install context-guard@session-optimizer-marketplace`; Codex: `codex plugin marketplace add cdeust/session-optimizer` + `codex plugin add context-guard@session-optimizer-codex`	A `Stop` hook enforces a per-model context budget: at the WARN threshold it writes a mechanical checkpoint stub — on Claude Code it delegates persistence to a budgeted `memory-writer` subagent as a reflection pause; on Codex the model writes the stub itself (no subagent-spawn tool is assumed) — at the hard cap it forces checkpoint → `/clear` → resume. On Claude Code a `SubagentStop` tracker also surfaces true session spend (main thread + subagents)
