What is open-bsp-api CLAUDE.md?

Project instructions for an Open BSP API, a multi-tenant WhatsApp Business Platform service built with Deno, PostgreSQL, and Supabase Edge Functions. They describe the project and the checks that should match continuous integration.

Use them when formatting, linting, type-checking, or debugging the API, its Supabase functions, or its plugin with Deno.

They prevent misleading validation results caused by running Deno checks from the wrong directory. They also explain how to verify edge functions and other packages correctly.

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	$0.01620	$0.01620
Opus 5.5	$0.00648	$0.00648

Security

Grade A, and why

open-bsp-api CLAUDE.md scanned grade A with 1 finding 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 3d 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.

Project overview

Open BSP API — a multi-tenant WhatsApp Business Platform integration built with Deno, Postgres, and Supabase Edge Functions. See README.md for full details.

Local checks must match CI (deno)

CI (.github/workflows/check.yml) runs:

deno fmt --check
cd supabase/functions && deno lint && deno check .
cd plugin && deno lint && deno check .

deno check only works from inside the package dir. Run cd supabase/functions && deno check . — NOT deno check <file> from the repo root. The import map lives in supabase/functions/deno.json (there is no root deno.json), so checking a file from the root resolves no bare specifiers and prints false Import "@supabase/supabase-js" not a dependency / "ky"/"zod"/"postgres" errors. These are an artifact of the wrong CWD, not real errors — don't treat them as a pre-existing baseline.

The .claude/settings.json PostToolUse hook runs deno check <file> without cd and swallows output with || true, so it always "passes" for functions files and verifies nothing there. Run the CI command yourself to actually verify.

deno fmt output is deno-version-dependent. The repo pins fmt config (lineWidth 80, semicolons, double quotes) but not the deno binary (CI uses v2.x). A different local deno can report spurious diffs on generated files (e.g. _shared/db_types.ts). Only format files you actually changed; never reformat the whole tree to chase a version-difference diff.

Debugging production edge functions

Timestamps

The current date/time is NOT reliably in the conversation context. When querying logs with time ranges (e.g., "last 12 hours"), always run date -u first to get the actual current UTC time. Do not guess or hardcode timestamps.

Querying edge function logs

Use the Supabase Management API logs endpoint (or the Supabase MCP query_logs tool, which runs the same queries). Every source is one logs table, picked with source; nested fields are log_attributes['<key>']:

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.
