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

ss-show-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 6d 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

Show OpenSpec Capability

Discover and display the authoritative spec for a capability. This is the entry point for "see what exists, then read it" — don't list or grep openspec/ blindly before calling this skill.

Inputs

Optional: a capability name (matching a directory under openspec/specs/) or a keyword to search for. Omit both to get an index of all capabilities.

Process

  1. No input given — enumerate every directory under openspec/specs/. For each, read the ## Purpose section (or the first descriptive line) of its spec.md and print a one-line index entry: capability-name — <purpose>. If openspec/specs/ is empty or missing, report that this repository has no OpenSpec baseline yet — suggest running the ss-write-spec or ss-reverse-spec skill. Stop here.
  2. Input matches a capability directory exactly (openspec/specs/<capability>/) — read and display that spec.md in full.
  3. Input is a keyword — search every openspec/specs/*/spec.md (and, where useful, active openspec/changes/*/specs/*/spec.md, excluding archive/) for the text. Show each match with its capability name and the matching line or excerpt. If more than one capability matches, list them and ask the user which one to display in full.
  4. After displaying a capability, list the 5 most recent archive entries that touched it — e.g., by finding files matching openspec/changes/archive/*/specs/<capability>/spec.md and taking the last 5 in sorted order. For each, show the archive directory name, the first proposal heading if available, and a count of delta sections (ADDED / MODIFIED / REMOVED / RENAMED).

Output

Keep the surrounding commentary concise, but always include the full current spec text. Do not edit any files.

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.
