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 | $0.00057 | $0.03589 |
| Opus 5.5 | $0.00023 | $0.01436 |
| Sonnet 5.5 | $0.00011 | $0.00718 |
| Haiku 4.5 | $0.00006 | $0.00359 |
Grade A, and why
encrypted-dns 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 yesterday.
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 — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Supported protocols
| Protocol | RFC/Spec | Transport | Default port | TLS required |
|---|---|---|---|---|
| DoH | RFC 8484 | HTTPS POST with application/dns-message |
443 | Yes (HTTPS) |
| DoT | RFC 7858 | TCP + TLS, length-prefixed DNS wire format | 853 | Yes |
| DNSCrypt | dnscrypt.info spec | TCP, XSalsa20Poly1305 (ChaChaBox) | 443 | No (own crypto) |
| DoQ | RFC 9250 | QUIC bidirectional streams, length-prefixed | 853 | Yes (QUIC TLS) |
| ODoH | RFC 9230 | HTTPS POST with application/oblivious-dns-message, HPKE-encrypted payload |
443 | Yes (HTTPS + HPKE) |
All protocols use standard DNS wire format (RFC 1035) for the query and response payloads. The protocol layer only differs in how the wire bytes are transported and encrypted.
DoQ does not support SOCKS5 transport because SOCKS5 is TCP-only; the
resolver returns EncryptedDnsError::Request if you try.
Architecture
The crate (native/rust/crates/ripdpi-dns-resolver) is organized by concern, one
top-level <name>.rs module file plus a <name>/ directory of submodules for
each area. List the current layout rather than trusting a snapshot:
find native/rust/crates/ripdpi-dns-resolver/src -name '*.rs' | sort
At a high level:
pool.rs+pool/{builder,exchange,fallback_order,health_updates,ranking,tests}.rs--ResolverPool/ResolverPoolBuilder, the LRU fallback cache, and health-based rotation.resolver.rs+resolver/{connection,dispatch,dnscrypt_transport,doh,doq,doq_tests,dot,state,tcp}.rs--EncryptedDnsResolver, protocol dispatch (dispatch.rs), and per-protocol exchange logic;resolver/doh/further splits the manual HTTP/1.1 DoH path into request/response/chunked-body helpers.health.rs+health/{oracle_policy,registry,score,snapshot,tests}.rs--HealthRegistry, EWMA scoring.transport.rs+transport/{client,framing,normalize,util,wire}.rs-- shared TLS config, endpoint normalization (normalize.rs), DNS wire helpers, andextract_ip_answers().dnscrypt.rs+dnscrypt/{certificate,cipher,framing,identity,padding}.rs-- DNSCrypt crypto.doh_pipeline.rs+doh_pipeline/{builder,cache,https_bindings,ip_candidates,lookup,types}.rs-- higher-level DoH batch-lookup pipeline (DohResolverPipeline) used by the diagnostics/oracle side.https_service_binding.rs+https_service_binding/{cursor,dto,ech,records}.rs-- HTTPS/SVCB record parsing (used by ODoH config discovery and ECH).odoh.rs-- ODoH client-side config resolution and HPKE query/response handling (no submodule split yet).types/--EncryptedDnsProtocol,EncryptedDnsEndpoint,EncryptedDnsError,EncryptedDnsConnectHooks,OdohEndpointConfig, and related public types, re-exported fromlib.rs.tests/{mod,pipeline,pool,https_service_binding}.rs-- integration tests (see Testing patterns below).
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.

encrypted-dns is a skill published in the GitHub repository po4yka/RIPDPI (85 stars, last pushed yesterday), licensed BSD-3-Clause. It adds 57 tokens to every session and 3,589 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 2026-11-07.
