echobot-skill-authoring

echobot-skill-authoring is a skill for Claude Code, Codex from KdaiP/EchoBot. It costs 97 tokens per session (907 once invoked), scanned A, original, MIT.

A guide for creating and maintaining skills for the EchoBot repository. It defines how skill files, instructions, supporting resources, and activation rules should be organized.

In plain words
What is it for?
It helps create, revise, and validate skill folders, front matter, trigger descriptions, references, scripts, assets, and EchoBot's skill-loading behavior.
Why use it?
It helps keep skills discoverable and consistent, while reducing unnecessary instructions and preventing essential text from being hidden in unsupported files.

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

echobot-skill-authoring 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 7d 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.

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EchoBot Skill Authoring

Create or revise repository-local skills that EchoBot can discover and activate.

Authoring goals

  • Put project-specific skills under skills/<skill-name>/.
  • Use lowercase kebab-case for the folder name and the name frontmatter field.
  • Keep frontmatter minimal. EchoBot routing reads name and description from SKILL.md.
  • Keep name as a single-line value. description may be a single line or a YAML block scalar with > or |.
  • Write description as the trigger surface: what the skill does, when to use it, and what kinds of user requests or contexts should activate it. Include likely request phrasing when that improves triggering.
  • Keep the main body procedural and concise. Move deeper material into small files under references/ or scripts/.
  • Design for lazy loading. After activation, EchoBot exposes the body plus a resource summary. It does not auto-load bundled files.
  • Only put text resources that an agent may need to read into references/, scripts/, or agents/. read_skill_resource only reads UTF-8 text files.
  • Use assets/ for templates or binary output artifacts, not for essential instructions.
  • Do not treat agents/openai.yaml as required. Current EchoBot discovery ignores it.
  • Avoid extra docs like README.md or changelog files inside a skill unless the runtime truly needs them.

Frontmatter checklist

  • Keep name stable and specific. Renaming a skill changes explicit /skill-name and $skill-name activation.
  • Make description concrete. Good descriptions say both the task and the trigger context.
  • Do not put "when to use" guidance only in the body. The body is loaded after activation.
  • EchoBot currently ignores extra frontmatter keys. The validator is more permissive for compatibility, but project-local skills should usually keep only name and description.

Resource layout

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
