From c6d4c8e09eff794ef3862a6c9b406dca5174dc51 Mon Sep 17 00:00:00 2001 From: couragehong Date: Tue, 14 Jul 2026 16:12:59 +0900 Subject: [PATCH 1/4] feat(claude): inject capture/recall behavior via SessionStart hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The plugin's automatic capture/recall depended on the user copying Rune's guidance into their own CLAUDE.md (or invoking slash commands explicitly) — sessions without that guidance never captured or recalled anything. Ship a SessionStart hook (startup|resume|compact) that injects the automatic-behavior contract into the session context whenever Rune is active: - hooks/session-start.sh gates on ~/.rune/config.json state (RUNE_HOME honored): not "active" -> exit 0 with no output, no network, no token spend, mirroring the dormant fail-safe. - When active, it emits the recall-before-answering and capture-as-decisions-crystallize contract to stdout, which Claude Code injects like CLAUDE.md content — every session, including post-compaction resumes. - jq is used when available with a grep/sed fallback, so the hook works on machines without jq. Claude Code only: hooks are a plugin-level mechanism. Codex/Gemini coverage will come separately via MCP initialize instructions in rune-mcp.

Adds the teammate-benefit test, the extracted JSON field spec with status_hint (accepted vs proposed feeds the rerank status multiplier), and a correction-record protocol for when recall surfaces an outdated record. - Drop capture self-censoring: near-duplicates are the server-side novelty filter's job, not the capture gate's.
