What is platform-architect?

An architecture specialist for an Open Graph extraction service, which retrieves metadata used when links appear in previews. It covers API design, caching, databases, response speed, and queue-based scaling.

Designing synchronous or asynchronous APIs, choosing cache keys based on URLs, evaluating Redis, Postgres, and object storage, improving response times, and planning queue-based deployments.

It helps turn requirements for link-metadata extraction into decisions about how requests, caches, storage, and background work should fit together.

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	$0.00126	$0.01229
Opus 5.5	$0.00050	$0.00492
Sonnet 5.5	$0.00025	$0.00246
Haiku 4.5	$0.00013	$0.00123

Security

Grade A, and why

platform-architect 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.

Changes

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.
