super-spec AGENTS.md

Repository instructions for SuperSpec, a collection of portable instructions for AI coding agents that run across several agent tools.

In plain words
What is it for?
Use it to understand the project, validate its instruction files and manifests, check references after renames, and inspect how skills are organized.
Why use it?
It gives contributors one documented source for the repository's layout, checks, naming, and supported runtimes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

super-spec AGENTS.md 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 yesterday.

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.

SuperSpec — Repository Guide

SuperSpec is a spec-driven development toolkit for AI coding agents, shipped as portable Agent Skills (SKILL.md) that work across Claude Code, OpenAI Codex, Pi, and OpenCode from a single source — no per-platform builds.

This is a prompt/documentation repository: there is no application code, build step, or test suite. "Correctness" here means valid manifests, resolvable cross-references, and skills whose instructions match the documented design.

Verification commands

./scripts/validate.sh                      # the full check suite — run before pushing (CI runs it too)
claude plugin validate .                   # Claude Code plugin + marketplace manifests
ls skills | grep -c '^ss-'                 # skill count — INSTALL.md asserts this number
grep -rn 'ss-<old-name>' skills docs *.md  # after any rename/delete: zero dangling refs

End-to-end discovery checks (optional, used before releases):

claude plugin marketplace add ./ && claude plugin install super-spec@super-spec
cp -R skills /tmp/x/.agents/skills && cd /tmp/x && opencode debug skill   # lists ss-*

Architecture

One source, four runtimes

skills/ss-<name>/SKILL.md is the single source of truth. Each platform consumes it through its own manifest, all committed at the repo root:

  • Claude Code.claude-plugin/plugin.json + marketplace.json; the repo root is the plugin, skills auto-discovered.
  • Codex.codex-plugin/plugin.json + .agents/plugins/marketplace.json; the repo doubles as a Codex plugin marketplace.
  • Pipackage.json (keywords: ["pi-package"], "pi": {"skills": ["./skills"]}).
  • OpenCode — no package manager; users install via npx skills or copy into a discovery path.

Keep version in sync across all three plugin manifests when releasing — releases are automated with release-please; see RELEASING.md. INSTALL.md is the agent-executable install/upgrade/uninstall walkthrough.

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.
