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

ferrox-capture 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 4d 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

Mode routing:

  • default (no flag): Capture as a structured todo for later work → add-todo workflow
  • --note: Zero-friction idea capture (append/list/promote) → note workflow
  • --backlog: Add an idea to the backlog parking lot (999.x numbering) → add-backlog workflow
  • --seed: Capture a forward-looking idea with trigger conditions → plant-seed workflow
  • --list: List pending todos and select one to work on → check-todos workflow
  • --list-seeds: List/audit captured seeds (optional status filter) → list-seeds workflow
Flag Destination Workflow
(none) Structured todo in .planning/todos/ add-todo
--note Timestamped note file, list, or promote note
--backlog ROADMAP.md backlog section (999.x) add-backlog
--seed .planning/seeds/SEED-NNN-slug.md plant-seed
--list Interactive todo browser + action router check-todos
--list-seeds Read-only seed list/audit (optional status filter) list-seeds

Parse the first token of $ARGUMENTS:

  • If it is --note: strip the flag, pass remainder to note workflow
  • If it is --backlog: strip the flag, pass remainder to add-backlog workflow
  • If it is --seed: strip the flag, pass remainder to plant-seed workflow
  • If it is --list-seeds: strip the flag, pass remainder (optional status filter) to list-seeds workflow
  • If it is --list: pass remainder (optional area filter) to check-todos workflow
  • Otherwise: pass all of $ARGUMENTS to add-todo workflow

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.
