Implements developing-today/code#6125: all quota info from one source — the opencode quota subcommand. Quota is a provider function implemented in the provider (@opencode/ai/quota), porting the OpenChamber quota module's wire behavior without redesigning endpoints.

What

• packages/ai/src/quota/ — per-provider quota functions returning the module result shape, one result per credential instance: antigravity, claude, cline-pass, codex (with instance folding), command-code (plan read only), deepseek, groq, meta (portal read + key-endpoint cross-check), mistral (including the admin console budget read: API $15/mo + Vibe $150/mo dollar windows via CDP in-page fetch or stored console cookie), opencode-go (API key + Console OAuth), opendesign (reads OpenChamber's managed credential store read-only — the AMR key is refused by the billing API), openrouter, plus a built-in turso fetcher (org usage API, token resolved from BWS by name).
• opencode quota [--json] [PROVIDER...] [--all] in packages/cli — no args = every configured provider (disabled_providers skipped unless --all or explicitly named; turso always included, error entry if its token cannot resolve), JSON array one result per credential instance, exit non-zero iff a requested provider produced no successful result.
• Claude results carry credentialExpiresAt + credentialSource on success and error results alike.
• Groq has no first-party quota surface (evidence comment on code#6125): the provider probes response rate-limit headers and otherwise returns failureClass: no-quota-surface — never fabricated numbers.

Tests

• packages/ai/test/quota.test.ts — mistral budget fixture mapping ($ windows from usage_percentage), meta portal mapping, turso mapping, groq reset parsing: 7/7.
• packages/cli/test/quota.test.ts — exit-code grouping + human rendering: 4/4.
• tsgo clean in packages/ai and packages/cli.
• Note: packages/cli test/auth.test.ts has pre-existing load-sensitive 5s-timeout failures on this machine, present with and without this change (verified via stash).

Live proof (built binary, real credentials)

Built dist/cli-linux-x64/bin/opencode (v2.0.30+quota, channel prod) from this branch and ran it against the laptop's real credential store: default run emits 14 rows — every pool ok except claude (Anthropic 429 rate limit on the usage endpoint, reported honestly). Mistral shows API $0.84/$15 (5.61%) and Vibe $0.06/$150 (0.043%), reset 2026-12-01, matching console truth. Named quota meta command-code groq bypasses the disabled filter; meta reports via the key endpoint (portal session expired), groq reports no-quota-surface.
