pre-commit prefixes only entry[0] with the hook-repo clone path (cmd = (prefix.path(cmd[0]), *cmd[1:])), so the --config argument in .pre-commit-hooks.yaml resolved against the *consuming* repo's root and hard-failed every external run with E100. Two of the three hooks ADR-0014 promises were unusable. vale-wrap.sh now self-locates its config from BASH_SOURCE when no --config is supplied; an explicit --config still wins in all three argv forms and stays cwd-relative. Both manifests drop the argument and are kept byte-identical: the local repo: local config resolved --config correctly only because the consuming repo *was* this repo, and that divergence is why three review rounds missed the defect. Also in the wrapper: - replace GNU-only `realpath -m` with a portable abspath helper; -m is load-bearing (dest does not exist yet), so BSD realpath aborted the script under set -e on macOS - walk directory arguments instead of passing them through unflattened, which reported a clean 0-error run for files that fail when named explicitly - read/write with errors='surrogateescape' so one non-UTF-8 .md under a directory argument cannot abort the hook New test-vale-hooks-consumer.sh builds the hook repo from the working tree and points a file:// consumer at it, covering the manifest as a hook repo for the first time.

scripts/
Executable code bundled with this skill. Agents run scripts in this directory to perform repeatable operations rather than reinventing the logic each run.
When to add a script
Add a script when agents independently reinvent the same logic across runs — building the same parser, chart, or validation routine from scratch each time. Bundle it here once, tested and reliable.
Script requirements (agentskills.io)
Scripts must be designed for non-interactive, agentic execution:
- No interactive prompts — agents run in non-interactive shells. Accept all input via flags, env vars, or stdin. A script that blocks on TTY input hangs indefinitely.
- Expose
--help— this is how agents learn your script's interface. Keep the output concise; it enters the agent's context window. - Structured output — write data (JSON, CSV, TSV) to stdout. Write progress, warnings, and diagnostics to stderr.
- Idempotent — prefer "create if not exists" over "create and fail on duplicate". Agents may retry on failure.
- Meaningful exit codes —
0for success, non-zero for failure. Use distinct codes for different failure types; document them in--help. - Dry-run support — add
--dry-runfor destructive operations.
Self-contained scripts
Bundle dependencies inline so the agent can run the script with a single command.
Python (PEP 723 + uv):
# /// script
# dependencies = ["requests>=2.31,<3"]
# requires-python = ">=3.11"
# ///
import requests
uv run scripts/my-script.py
