autospec: Skill for OpenCode

.opencode/skills/create-spec/SKILL.md

create-spec is a skill for OpenCode from Hundia/autospec. It costs 17 tokens per session (123 once invoked), scanned A, original, MIT.

A workflow for writing a new feature specification in the AutoSpec format and turning it into possible follow-up work.

In plain words
What is it for?
Use it to document a feature, follow the project's existing specification naming and numbering, and suggest sprint tickets for implementation.
Why use it?
It helps turn a vague feature idea into a clear, project-specific plan that can be added to a task backlog.

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

create-spec 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 2mo 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

Use this skill when the user wants a new feature spec written in AutoSpec format.

  • Read skills/claude/create-spec.md and use it as the detailed workflow.
  • Ask clarifying questions only when required by the workflow.
  • Follow existing spec numbering and naming conventions.
  • Keep the output concrete, project-specific, and ready to convert into backlog work.

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.
