A guide for reading and writing the FastKV configuration registry, including its key layout, signer-based namespaces, integrity checks, and locally composed runtime configurations.

Use it to publish configurations, combine another runtime's interface, host, API, or plugins, or debug unresolved published configurations.

It helps explain how published configurations are stored and combined, and how to investigate configurations that do not resolve correctly.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add NEARBuilders/everything-dev --skill registry

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	$0.00058	$0.01755
Opus 5.5	$0.00023	$0.00702
Sonnet 5.5	$0.00012	$0.00351
Haiku 4.5	$0.00006	$0.00176

Measured 2d ago against content hash 20311d1b7d64, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

registry 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 2d 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.

registry is a skill published in the GitHub repository NEARBuilders/everything-dev (5 stars, last pushed yesterday), with no licence file. It adds 58 tokens to every session and 1,755 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-04.
