# Add marketplace (one time)
/plugin marketplace add ruslands/plugins

# Install any plugin by name
/plugin install < plugin-name > @plugins

Codex installs plugins from a local marketplace rather than a direct shell install command.

1. Clone this repo locally and open it in Codex.
2. This repo already includes .agents/plugins/marketplace.json.
3. If Codex was already open when you added or changed that file, restart Codex.
4. In Codex, open /plugins.
5. Choose Plugins and install the plugins you want.

This README only covers installing this marketplace. For generic Codex marketplace examples and maintainer docs, see CLAUDE.md.

gemini extensions install --path ./plugins/<plugin-name>

cursor plugin install < plugin-name > @plugins

When Claude Code auto-summarizes a long session, the default summary routinely drops the highest-signal facts. This plugin tells the summarizer to keep them:

• File paths under investigation so the next turn doesn't re-discover where you were
• Confirmed root causes so you don't re-debug what's already solved
• Open questions, metrics, and IDs that prose summaries usually round away
• Findings from expensive subagent runs that took minutes to gather

Runs on every /compact (manual) and every auto compaction. Claude Code only; Codex, Cursor, and Gemini CLI don't yet expose a comparable summary hook.

Hooks:

• precompact_priorities.sh - Priority-preservation instructions for the compaction summarizer

Adds the two missing pieces Claude Code's telemetry needs to power a usage dashboard:

• Sticky session ID per project: resumed conversations stay one session, not dozens
• Categorized rejection reasons (profanity, wrong target, scope drift, retry, and more): chart why Claude pushes back

Per-device data is already in Claude Code's built-in OpenTelemetry stream. Pairs naturally with openobserve-skills for the dashboard side.

Hooks:

• session_start_chat_id.py - SessionStart hook that emits a sticky per-project chat_id
• user_prompt_reject_feedback.py - UserPromptSubmit hook that categorizes tool-rejection reasons
