What is fizzy-cli AGENTS.md?

Repository instructions for Fizzy CLI, a command-line client for the Fizzy service, with Go commands, configuration, API access, output rendering, and integration tests.

Use them when adding or debugging CLI commands, API calls, configuration, rendering, file transfers, MCP support, or end-to-end tests.

They explain which client layer each command should use and where the main parts of the codebase live.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01589	$0.01589
Opus 5.5	$0.00636	$0.00636
Sonnet 5.5	$0.00318	$0.00318
Haiku 4.5	$0.00159	$0.00159

Security

Grade A, and why

fizzy-cli AGENTS.md 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 1mo 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.

SDK Architecture

Commands use the fizzy-sdk (github.com/basecamp/fizzy-sdk/go/pkg/fizzy) for API access:

getSDK() returns *fizzy.AccountClient — account-scoped SDK client for most commands
getSDKClient() returns *fizzy.Client — root client for account-independent operations (e.g. identity)
getClient() (deprecated) returns client.API — legacy client, used only for file upload, download, multipart PATCH, and board migration

SDK service methods return typed structs (e.g. *generated.Board, []generated.Card). Helper functions convert to the any types the output layer expects:

normalizeAny(data) — JSON-round-trips any value (typed structs, json.RawMessage, maps) to map[string]any / []map[string]any
jsonAnySlice(pages) — converts []json.RawMessage from GetAll() pagination to []map[string]any
convertSDKError(err) — converts SDK errors to *output.Error
toSliceAny(v) — normalizes []map[string]any or []any to []any for iteration

Account can be a slug or numeric ID.

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.
