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

fizzy 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fizzy — Project Management via Fizzy CLI

Full CLI coverage: boards, cards, columns, comments, steps, reactions, tags, users, notifications, pins, webhooks, account settings, search, and board migration.

Requires the Fizzy CLI and jq. Check with fizzy auth status before the first command.

Agent Invariants

MUST follow these rules:

  1. Cards use NUMBER, not ID — fizzy card show 42 uses the card number. Other resources use their id field.
  2. Parse JSON with jq to reduce token output — fizzy card list | jq '[.data[] | {number, title}]'
  3. Check breadcrumbs in responses for available next actions with pre-filled values
  4. Check for board context via .fizzy.yaml or --board flag before listing cards
  5. Rich text fields accept HTML — use <p> tags for paragraphs, <action-text-attachment> for inline images
  6. Card description is a string, but comment body is a nested object — .description vs .body.plain_text
  7. Ask the user before irreversible commands — delete, deactivate, and account join-code-reset cannot be undone. State what will be affected and wait for a yes. For migrate board, run with --dry-run first and show the preview before the real run.
  8. Use the default output — the piped JSON envelope. Do not add --agent, --quiet, or --markdown: they drop the {ok, data, breadcrumbs} envelope that invariants 2-3 and every jq example rely on.

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.
