Bump all manifests to 6.1.0 and add RELEASE-NOTES for v6.1.0:
- Compress the using-superpowers bootstrap and prune per-harness
tool-mapping references (lower per-session token cost).
- Add a Codex marketplace manifest so the plugin installs from Codex;
drop the Codex SessionStart hook.
- Remove Gemini CLI support (Google EOLed the Gemini CLI 2026-06-18).
Commit 1f0c76e removed the Codex SessionStart hook — dropping the hooks
field from .codex-plugin/plugin.json and deleting hooks-codex.json — but
left test-marketplace-manifest.sh asserting the old hooks pointer, so the
test has failed on dev since. Assert the field is absent instead, locking
in the no-Codex-hooks decision.
The bootstrap is injected into every session, so its token cost is paid
constantly. Condense it without dropping behavior-shaping content:
- Replace the graphviz skill-flow diagram with the prose it encoded (the
1% rule, the plan-mode to brainstorm gate, announce + checklist to todos).
- Fold the standalone Instruction-Priority section into User Instructions.
- Drop the per-platform 'How to Access Skills' walkthrough.
- Trim the Platform Adaptation pointer to the harnesses that still have a
reference file (Codex, Pi, Antigravity).
Keeps the full Red Flags rationalization table, skill priority framed as
process-before-implementation, and user-instruction precedence.
The verbose action-to-tool tables and skill-loading explainers in the
per-harness reference files restated guidance modern agents already
follow. Trim each file to the harness-specific notes that still carry
weight (subagent dispatch, task tracking, instructions-file paths), and
delete claude-code-tools.md and copilot-tools.md, which had nothing left
that wasn't generic.
Google EOLed the Gemini CLI on 2026-06-18; the extension can no longer
be installed or updated. Remove Gemini from the install docs, the
subagent-capable platform lists, and the eval-harness description, and
delete its tool-mapping reference.
Codex reliably triggers skills on its own, and the SessionStart hook
made the UX worse rather than better. Drop the Codex hook config and
its registration in the plugin manifest.
Bug: the SessionStart hook matcher in hooks-codex.json included "resume",
causing the superpowers bootstrap to re-fire on every Codex session resume.
Fix: align with Claude's hooks/hooks.json matcher "startup|clear|compact":
- drop "resume" (the bug: resume should not trigger re-bootstrap)
- add "compact" (so bootstrap re-injects after context compaction, like Claude)
Before: "matcher": "startup|resume|clear"
After: "matcher": "startup|clear|compact"
Prompt: Jesse questioned whether the PR should remove the hooks config from the Codex plugin manifest.
Runtime investigation showed Codex accepts a committed plugin manifest with hooks and installs the plugin successfully. Removing the field changes behavior: Codex falls back to the default hooks/hooks.json, which uses the non-Codex session-start hook and CLAUDE_PLUGIN_ROOT path, instead of hooks/hooks-codex.json and the session-start-codex script.
Changes: restore .codex-plugin/plugin.json hooks to ./hooks/hooks-codex.json and update the Codex marketplace manifest test to require that Codex-specific hook pointer instead of rejecting hooks.
Validation: bash tests/codex/test-marketplace-manifest.sh; scripts/lint-shell.sh tests/codex/test-marketplace-manifest.sh; bash tests/codex-plugin-sync/test-sync-to-codex-plugin.sh; bash tests/kimi/test-plugin-manifest.sh; bash tests/shell-lint/test-lint-shell.sh.
Prompt: Jesse asked for a new worktree off the local superpowers dev branch to add the Codex manifest after diagnosing why github.com/obra/superpowers did not show installable Codex plugins.
Root cause: Codex marketplace sources expect a .agents/plugins/marketplace.json at the marketplace root. The superpowers repo only had the Claude marketplace file and the Codex plugin manifest, so Codex could configure the marketplace name but found no installable plugin entries.
Changes: add a repo-local Codex marketplace manifest for superpowers-dev that points at this same repository root via the same-root source pattern Codex already accepts; add a focused marketplace manifest test; remove the unsupported hooks field from .codex-plugin/plugin.json so the plugin validator accepts the manifest.
Validation: bash tests/codex/test-marketplace-manifest.sh; uv run --with PyYAML python /Users/jesse/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py /Users/jesse/git/superpowers/superpowers/.worktrees/codex-marketplace-manifest; throwaway HOME codex plugin marketplace add/list/add; bash tests/codex-plugin-sync/test-sync-to-codex-plugin.sh; bash tests/kimi/test-plugin-manifest.sh; bash tests/shell-lint/test-lint-shell.sh; scripts/lint-shell.sh tests/codex/test-marketplace-manifest.sh.
# Codex auto-discovers a plugin's hooks/hooks.json whenever the Codex manifest
# has no `hooks` field: load_plugin_hooks falls back to a hardcoded
# DEFAULT_HOOKS_CONFIG_FILE = "hooks/hooks.json" and registers it. That file is
# the Claude Code SessionStart hook, it is tracked in this repo, and this
# marketplace installs the whole repo root (source url "./"), so on Codex the
# fallback re-registers the SessionStart hook and its install-time trust prompt.
# Declaring an empty inline hooks object ({}) parses as an empty inline hook set
# and suppresses the auto-discovery. An absent field, an empty array ([]), and
# an empty inline list all collapse back to the fallback, so the value must be
# exactly an empty object.
