On-demand wrapper over scripts/preflight/run-all.sh. Runs Tier 1 bash linters against a file, command, or arbitrary content. Returns 0 pass / 1 warn / 2 fail. Used by /aura-frog:preflight check and contributors authoring custom hooks.
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
> **AI-consumed reference.** Optimized for Claude to read during execution. > Human-readable explanation: see [docs/architecture/HIERARCHICAL_PLANNING.md](../../../docs/architecture/HIERARCHICAL_PLANNING.md) > or [docs/getting-started/](../../../docs/getting-started/) depending on topic. # Pre-flight Validator **STATUS — v3.7.0-beta.1.** Thin wrapper over `aura-frog/scripts/preflight/run-all.sh`. ## When this skill runs vs. when the hook runs - **`hooks/pre-flight-validate.cjs`** — auto-fires on every PreToolUse for Bash/Edit/Write/Read. Blocks tool call on fail. **You don't have to do anything for this — it's automatic.** - **This skill** — explicit invocation when you want to validate something the hook doesn't see. Examples: validating a markdown file before committing, dry-running a Bash command's safety, batching a directory of plan files through frontmatter validation. ## Behavior 1. Resolve target: file path / Bash command string / stdin content 2. Run `bash aura-frog/scripts/preflight/run-all.sh` with the appropriate flags 3. Surface exit code + stderr to caller ## Tier 1 linters (per spec §20.2) | Script | Checks | |---|---| …

How to install
mdr add nguyenthienthanh/aura-frog/preflight-validator@sha256:2a742e9400837adaThe line at the top of this page pins the label git:20260515.6be9f59, 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.
