Composable block system for OpenClaw cron job prompts. Assembles cron prompts from reusable markdown blocks so cross-cutting changes (e.g. git identity, error handling) only need updating in one place. Use when managing multiple cron jobs, authoring a cron manifest, composing blocks into prompts, running cron-compose.py, or asking about cron prompt assembly, block composition, manifest format, or `apply`/`lint`/`diff`/`sync`/`stats` commands.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cron Composer 🧩 STARTER_CHARACTER = 🧩 Composable block system for OpenClaw cron job prompts. Define reusable blocks once; assemble prompts from them via a YAML manifest. **Why:** When you have many cron jobs sharing common behaviours (git identity, error handling, backup patterns), editing each prompt individually is error-prone. Cron Composer centralises shared logic in block files and assembles final prompts on demand. ## Quick Start ```bash # Set this to the actual installed package directory; do not assume the workspace. SKILL_DIR="/path/to/skills/cron-composer" python3 -m pip install -r "$SKILL_DIR/requirements.txt" # List all crons in manifest python3 "$SKILL_DIR/scripts/cron-compose.py" "$SKILL_DIR/example-manifest.yaml" list # Preview assembled prompt (dry-run) python3 "$SKILL_DIR/scripts/cron-compose.py" /path/to/my-manifest.yaml apply my-cron --dry-run # Apply one cron python3 "$SKILL_DIR/scripts/cron-compose.py" /path/to/my-manifest.yaml apply my-cron # Apply all crons python3 "$SKILL_DIR/scripts/cron-compose.py" /path/to/my-manifest.yaml apply --all # Validate manifest python3 "$SKILL_DIR/scripts/cron-compose.py" /path/to/my-manifest.yaml lint ``` …

How to install
mdr add suryast/free-ai-agent-skills/cron-composer@sha256:5a1522bdf73402c4The line at the top of this page pins the label git:20261010.2c2162d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
