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

textual 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.

examples/textual/SKILL.md · 48 lines

What it actually says

textual

Reference skill bundle used as the Califa Cards generator fixture. The skillcard build examples/textual/ regression test regenerates card.json and skill-card.md from this SKILL.md, the authored sidecar, the repo config, the committed scan report, and the evals results — and must reproduce the committed pair byte for byte (the deterministic acceptance proof in SPEC.md section C).

Everything the generator needs lives in this directory:

  • SKILL.md — the skill's identity (name, version, summary, description, triggers, output, dependencies, and the hashed security surface: external_endpoints, permissions).
  • card.authored.yaml — the authored governance overlay (status, accepted findings, optional provenance pins); excluded from content_hash.
  • .skillcard.toml — repo config (owner, repo tier/url, license, scanner pin).
  • scan.json — the SkillSpector --format json report.
  • evals/evals.json — eval definitions plus the aggregate results block.
Files

What ships with it

7 files 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.
