The routing-target check understood only a single-arrow clause naming a bare skill, so most real boundary prose was silently skipped rather than verified. Two of those silences were fail-open: an unrecognised token following a target dropped that target from the check entirely, and a skill directory with no SKILL.md still resolved as a valid routing target, so a broken route passed. Multi-target arrow clauses now draw a SUGGESTION instead of being ignored, hand-invocation phrasing is carved out so it is not read as a route, and a dotted filename parses into a new `unparsed` status rather than disappearing. Three test fixtures had been relying on the SKILL.md-less directory resolving as a target; they are corrected alongside the check. Addresses #107, #108, #110.
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
