validate

A validation command that checks YAML syntax and manifest structure without contacting GitHub. YAML is a human-readable configuration-file format.

In plain words
What is it for?
Use it to check one manifest, a directory, or several paths, and optionally treat unknown YAML resource types as errors.
Why use it?
It catches configuration errors locally before a plan or apply operation reaches GitHub.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 331 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

validate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Check YAML syntax and schema without contacting GitHub.

gh infra validate [path...]

Path

One or more paths can be given. When multiple paths are provided, manifests from all paths are validated together.

Argument Example Behavior
(none) or . gh infra validate All *.yaml / *.yml in the current directory
File gh infra validate repos/my-cli.yaml That file only
Directory gh infra validate repos/ All *.yaml / *.yml directly under it (subdirectories are ignored)
Multiple gh infra validate repos/ files/ Manifests from all listed paths combined

Overlapping paths (e.g., . and ./repos/) are rejected to prevent duplicate processing.

YAML files that are not gh-infra manifests are silently skipped. Use --fail-on-unknown to treat them as errors.

Flags

Flag Description
--fail-on-unknown Error on YAML files with unknown Kind (default: silently skip)

Examples

# Validate all files in a directory
gh infra validate ./repos/

# Validate multiple directories at once
gh infra validate ./repos/ ./files/

# Validate a single file
gh infra validate ./repos/my-cli.yaml

Exits with code 0 if all files are valid, non-zero otherwise.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

validate is a command published in the GitHub repository babarot/gh-infra (134 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 331 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
