# Shared References This directory contains shared reference documents used by multiple skills: - `validation-contract.md` - Verification requirements for accepting spawned work - `references/backend-codex-subagents.md` - Concrete examples for Codex session agents - `references/backend-background-tasks.md` - Fallback: background shell tasks - `references/backend-inline.md` - Degraded single-agent mode (no spawn) - `references/codex-cli-verified-commands.md` - Verified Codex CLI command shapes and caveats - `references/cli-command-failures-2026-02-26.md` - Dated failure log and mitigations from live runs - [references/content-hash-cache.md](references/content-hash-cache.md) - SHA-256 content-based caching for file processing - [references/compaction-signals.md](references/compaction-signals.md) - Tool-call-based strategic compaction signals These are **not directly invocable skills**. They are loaded by other skills (council, crank, swarm, research, implement) when needed. ## CLI Availability Pattern All skills that reference external CLIs MUST degrade gracefully when those CLIs are absent. ### Check Pattern ```bash # Before using any external CLI, check availability if command -v bd &>/dev/null; then # Full behavior with bd else echo "Note: bd CLI not installed. Using plain text tracking." fi ``` ### Fallback Table | Capability | When Missing | Fallback Behavior | |------------|--------------|-------------------| | `ao` | Knowledge flywheel unavailable | Write le
