Gemini CLI has been EOLed by Google as of 6/18/26

Condense the injected bootstrap without dropping behavior-shaping content:
replace the graphviz flowchart with prose (1% rule, plan-mode->brainstorm gate,
announce + checklist->todos), fold Instruction-Priority into User Instructions,
and drop the per-platform skill-loading section. Keep the full Red Flags
rationalization table (all 12), the platform tool-mapping pointer (now a
skill-relative path list), skill priority framed as a category (process before
implementation, not just the two named skills), and user-instruction precedence
plus the WHAT/HOW guard.

Snapshot on a local branch for review — NOT final, NOT for dev. Open items:
the dropped "Skill Types" (rigid/flexible) section, and evals for user
preferences overriding skills. Clean Docker evals show the more-aggressive
g-minimal preserves load-bearing triggering across opus/sonnet/haiku/codex/
gemini/kimi; this variant keeps more content.

 # Superpowers Release Notes
 
-## v6.1.0 (2026-06-30)
-
-### Lower Per-Session Token Cost
-
-The `using-superpowers` bootstrap is injected into every session, so its size is paid for constantly. This release trims it and the per-harness references it points to, without dropping behavior-shaping content.
-
-- **Compressed the `using-superpowers` bootstrap.** Replaced the graphviz skill-flow diagram with the prose it encoded, folded the standalone Instruction-Priority section into User Instructions, dropped the per-platform "How to Access Skills" walkthrough, and trimmed the Platform Adaptation pointer to the harnesses that still ship a reference file. The full Red Flags rationalization table and the user-instruction precedence rules are unchanged.
-- **Pruned the per-harness tool-mapping references.** The verbose action-to-tool tables restated guidance modern agents already follow. Each reference file is trimmed to the harness-specific notes that still carry weight — subagent dispatch, task tracking, instructions-file paths — and `claude-code-tools.md` and `copilot-tools.md`, which had nothing harness-specific left, are deleted.
-
-### Codex
-
-- **Codex can install from the marketplace.** Codex marketplace sources expect a `.agents/plugins/marketplace.json` at the marketplace root; the repo only shipped the Claude marketplace file, so Codex could name the marketplace but found no installable plugin entries. A repo-local Codex marketplace manifest now points at the same repository root, so the plugin is installable from Codex.
-- **Codex no longer ships a SessionStart hook.** Codex reliably triggers skills on its own, and the bootstrap hook made the UX worse rather than better. The Codex hook config (`hooks-codex.json`) and its manifest registration are removed.
-
-### Harness Support
-
-- **Gemini CLI support removed.** Google EOLed the Gemini CLI on 2026-06-18; the extension can no longer be installed or updated. Gemini is gone from the install docs, the subagent-capable platform lists, and the eval-harness description, and its tool-mapping reference is deleted.
