What is develop-opensecret-sdk?

A set of instructions for developing and reviewing OpenSecret’s TypeScript/React and Rust software development kits. These SDKs let browser, React, and native applications communicate with OpenSecret services using their defined authentication, encryption, and typed interfaces.

Use it when changing or reviewing SDK APIs, authentication, attestation, encrypted transport, tests, package contents, versions, or an authorized publishing handoff.

It clarifies which responsibilities belong in the SDKs and which belong to OpenSecret or Maple. It also helps preserve the separate package boundaries and integration version used by the application.

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	$0.00074	$0.00994
Opus 5.5	$0.00030	$0.00398
Sonnet 5.5	$0.00015	$0.00199
Haiku 4.5	$0.00007	$0.00099

Security

Grade A, and why

develop-opensecret-sdk 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.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Develop the OpenSecret SDK

Work from OpenSecretCloud/Maple/sdk. Read the repository-root AGENTS.md, sdk/README.md, the affected implementation and tests, and the root .github/workflows/sdk-*.yml files relevant to the change.

The SDK source is part of the Maple repository, but its TypeScript and Rust package boundaries remain independently versioned and publishable:

src/ builds @opensecret/react for browser and React consumers.
rust/ builds the opensecret crate for native consumers.
frontend/package.json is authoritative for whether Maple's browser client consumes a published TypeScript version or the in-tree file:../sdk package.
desktop Maple and proxy/ consume the in-tree Rust crate through versioned path dependencies. iOS and Android do not compile those desktop-only consumers.

Do not commit, push, open a PR, publish, or alter Maple's application dependency wiring unless the user authorizes that action.

Keep protocol ownership clear

OpenSecret owns authentication and authorization truth, public HTTP semantics, provider policy, persistence, and usage accounting. The SDKs own client-side attestation, encrypted sessions, typed contracts, authentication state, and safe transport adaptation. Maple owns application presentation and local device behavior.

For a public contract change, inspect the exact OpenSecret backend revision and both SDK implementations when they expose the affected behavior. Preserve old-client/new-server and new-client/old-server compatibility where clients can update independently. Do not weaken HTTPS, PCR validation, attestation, key exchange, randomness, retry safety, or sanitized errors to accommodate a caller.

Develop and validate

Use the SDK's pinned Nix shell. For TypeScript/React work:

nix develop --no-update-lock-file -c bun install --frozen-lockfile --ignore-scripts
nix develop --no-update-lock-file -c bun run format:check
nix develop --no-update-lock-file -c bun run build
nix develop --no-update-lock-file -c bun test --timeout 30000

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.
