+# Phase 46 Plan 02: Installing AgCron SKILL.md Binary-First Rewrite Summary
+
+Rewrote the `skills/agcron/installing-agcron/SKILL.md` install guide to lead with Homebrew and shell installer (pre-built binaries), demoting build-from-source to a fallback section.
+
+## What Was Done
+
+### New Section Order in SKILL.md
+
+1. Frontmatter + title + intro paragraph (rewritten)
+2. **## Quick Install** (new — Option 1: Homebrew, Option 2: shell installer)
+3. **## Configuration** (preserved verbatim, was lines 62-132)
+4. **## Verifying the Installation** (preserved verbatim, was lines 134-149)
+5. **## Running the Daemon** (preserved verbatim, was lines 151-169)
+6. **## Running Tests** (preserved verbatim, was lines 171-179)
+7. **## Troubleshooting** (preserved verbatim, was lines 181-187)
+8. **## Building from Source (Fallback)** (new fallback section at bottom)
+
+### Sections Rewritten vs Preserved
+
+| Section | Action |
+|---------|--------|
+| Frontmatter description | Rewritten — removed "from source" |
+| Intro paragraph | Rewritten — removed "from source", added binary availability note |
+| Prerequisites (Rust toolchain) | Removed entirely |
+| Building from Source (old) | Replaced by pointer-only fallback at bottom |
+| Binary Installation (old, post-build copy) | Removed entirely |
+| Quick Install (Homebrew + shell installer) | New section |
+| Configuration through Troubleshooting | Preserved verbatim |
+| Building from Source (Fallback) | New pointer-only section at bottom |
+
+### URLs and Commands Verified Correct
+
+- Installer URL: `https://github.com/SpillwaveSolutions/agent-cron/releases/latest/download/agcron-installer.sh`
+  (NOT the wrong `raw.githubusercontent.com/main/install.sh`)
+- Homebrew: `brew tap SpillwaveSolutions/agcron` + `brew install agcron`
+- PATH note: `export PATH="$HOME/.cargo/bin:$PATH"` (correct because dist-workspace.toml uses `install-path = "CARGO_HOME"`)
+- Gatekeeper note: `xattr -cr $(which agcron)`
+
+### cargo test Result
+
+All tests passed. No Rust source files were modified.
+
+```
+test result: ok. 4 passed; 0 failed; 10 ignored; 0 measured; 0 filtered out; finished in 1.26s
+```
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Commits
+
+| Task | Description | Commit |
+|------|-------------|--------|
+| 1 | Rewrite SKILL.md with binary-first structure | 840d0dc4 |
+
+## Self-Check: PASSED
+
+- [x] `skills/agcron/installing-agcron/SKILL.md` exists and contains Quick Install section
+- [x] Commit 840d0dc4 exists
+- [x] Section order: Quick Install (line 10) < Configuration (41) < Troubleshooting (161) < Building from Source Fallback (168)
+- [x] Description reads "Install, configure, and verify the agent-cron daemon." (no "from source")
+- [x] Correct installer URL present (releases/latest/download)
+- [x] cargo test passes
