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

gsd-add-phase 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 27d 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

Routes to the add-phase workflow which handles:

  • Phase number calculation (next sequential integer)
  • Directory creation with slug generation
  • Roadmap structure updates
  • STATE.md roadmap evolution tracking

<execution_context> @/Users/richardhightower/clients/spillwave/src/agent-brain/.opencode/get-shit-done/workflows/add-phase.md </execution_context>

Roadmap and state are resolved in-workflow via init phase-op and targeted tool calls.

The workflow handles all logic including:

  1. Argument parsing and validation
  2. Roadmap existence checking
  3. Current milestone identification
  4. Next phase number calculation (ignoring decimals)
  5. Slug generation from description
  6. Phase directory creation
  7. Roadmap entry insertion
  8. STATE.md updates

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.
