At a glance

Draft a new Claude Code or Codex skill at .claude/skills/<name/SKILL.md (or .agents/skills/<name/SKILL.md for Codex), using the Anthropic Skills format.

  • The user wants to create
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Scaffold a custom skill for an agentic coding tool

What it does

Ad Skill is an agent skill from alexandremendoncaalvaro/CorridorKey-Runtime. Draft a new Claude Code or Codex skill at .claude/skills/<name/SKILL.md (or .agents/skills/<name/SKILL.md for Codex), using the Anthropic Skills format. Use when the user wants to create, write, draft, or scaffold a custom skill for an agentic coding tool. Asks one question per missing field; never invents skill names or triggers.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It works with OpenAI. The repository describes itself as: Native AI keying runtime and OFX plugin for DaVinci Resolve, built in collaboration with Corridor Digital.

When your agent uses it

  • The user wants to create
  • Scaffold a custom skill for an agentic coding tool

Example prompts

  • “/ad-skill”

What it can do on your machine

Read from SKILL.md and the folder at commit e632fa5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ad Skill loads about 871 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 378 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~871

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 378 words (~871 tokens).

“Drafts .claude/skills//SKILL.md (Claude Code) or .agents/skills//SKILL.md plus agents/openai.yaml (Codex). Spec: code.claude.com/docs/en/skills. Open standard: agentskills.io. Examples: github.com/anthropics/skills.”
