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

superspecs 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

SuperSpecs Active

Four phases, always in order: Plan → Execute → Verify → Ship

Commands

Phase Command What
1.1 Plan /discuss Capture decisions before planning
1.2 Plan /spec Write spec (requires DISCUSS.md)
1.3 Plan /grill Mandatory gate — READY verdict required before execution
2.1 Execute /pick-spec Validate + prepare execution
2.2 Execute /branch Create branch/worktree
2.3 Execute /subagent Parallel task dispatch
2.4 Execute /tdd RED-GREEN-REFACTOR
2.5 Execute /code-review Between tasks, critical blocks
3 Verify /verify Full suite + scenario coverage, then wiki import
4 Ship /ship PR + archive + next cycle

Hard Rules

  1. No implementation code before a failing test
  2. Critical code-review findings block all progress
  3. Spec must fit a fresh 200k context window
  4. /grill must reach READY verdict before /pick-spec
  5. Every shipped feature gets a wiki page

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.
