Summary

  • CodeBuddy presets seeded a static manifest-derived catalog and kept liveModels: false, so a fresh install advertised models the client cannot serve and hid models it can. The account configuration is key-scoped and served fresh: a CN account lists kimi-k3-2, glm-5.3, and deepseek-v4.1-flash, while the manifests shipped with both CLI 2.126.0 and 2.155.0 still describe the kimi-k3-1 generation.
  • This PR discovers the account roster through a key-authenticated product configuration request. src/adapters/codebuddy/live-models.ts performs GET {canonicalBaseUrl}/v3/config with the configured key as X-API-Key (the same endpoint the CLI's own product configuration uses) and reads data.agents[].models — the roster the CLI exposes for --model, but answered for the KEY's own account, not the CLI login's. An absent or invalid key answers the anonymous envelope (no agents, empty models), so no roster exists to misattribute. Review follow-up (260923): this replaces the earlier --help probe, whose roster is the CLI's signed-in account regardless of the configured key — the exact flaw the 260923 bundle-round review named: the roster must be proven to belong to the key before it is cached. With the configuration request the proof is by construction: the roster only exists when the key authenticated, and the existing key-fingerprint cache scope now names the roster's actual authority.
  • Design and slicing discussion: [Feature]: CodeBuddy capture-only tool bridge and account-roster model discovery (direct merge requested) #5146. Rebased onto current dev (260925); local validation rerun on the new head: 59 focused tests pass, typecheck clean. (roster authority: key-authenticated configuration) [reattestation retry 260923] Companion PR: the capture-only tool bridge (reference branch feat/codebuddy-tool-bridge carries both).

Verification

  • bun test focused suites (64 tests across the codebuddy live-models/adapter/mcp-server suites) — pass, including the rewritten live-models suite: parser cases for the authenticated and anonymous envelopes, fetch cases pinning the per-region endpoint URL, the X-API-Key header, and the CLI-shaped User-Agent, the non-200/timeout/invalid-JSON failure modes, and the cross-key cooldown/fingerprint isolation plus the invalid-key never-caches case. bun x tsc --noEmit — clean. bun run privacy:scan — clean. bun run structure:check — clean.
  • Live (260923, CN gateway www.codebuddy.cn): fetchCodeBuddyModels with the real configured key returns the 17-id roster (hy4-preview-f ... deepseek-v4-pro), byte-identical to the CLI's --model list for a signed-in account of that key; the same call with a deliberately wrong key returns { ok: false, error: "empty", detail: "CodeBuddy answered the anonymous config: the key did not authenticate" }. Raw-gateway measurements behind the design: data.agents[0].models is the agent roster and data.models the wider account catalog; an invalid key answers the anonymous envelope with no agents; the gateway authenticates the key only behind a CLI/<v> CodeBuddy/<v> User-Agent (bare axios/fetch UAs get 400 12403 "check ua", and the version value is not validated — CLI/0.0.1 measures fine). The global endpoint (www.codebuddy.ai) shares the CLI's product-configuration code path; live verification ran on CN, global is covered by the mocked per-region fetch test.
  • Full suite (bun run test:changed on the rebased head, macOS): 24323 pass / 19 fail. The 19 failures are the known service/install/WSL/diagnostic environment families that reproduce identically on a clean dev checkout on this host (same families as every earlier run in this PR's history); none touch the codebuddy or catalog surfaces. Every codebuddy suite passes.

📝 Walkthrough

Walkthrough

CodeBuddy model discovery now reads the account-scoped CLI roster, validates model IDs, caches results by API-key fingerprint, and falls back to stale or static models when discovery fails. Global and CN providers enable the feature.

Changes

CodeBuddy live model discovery

Layer / File(s) Summary
CLI roster adapter and validation
src/adapters/codebuddy/live-models.ts, tests/providers/codebuddy-live-models.test.ts
The adapter runs codebuddy --help, parses the roster, filters invalid, duplicate, and custom: IDs, limits output, and returns typed failures. Tests cover parsing, scoped environment variables, binary resolution, missing binaries, and account isolation.
Catalog cache integration
src/codex/catalog/provider-models.ts, src/codex/catalog/model-hints.ts
The catalog resolves CodeBuddy profiles, scopes cache entries by SHA-256 API-key fingerprint, uses fresh or retained stale results, fetches live models on cache misses, and preserves configured defaults during fallback.
Provider rollout and validation support
src/providers/registry/entries-extended.ts, src/providers/codebuddy-models.ts, docs-site/src/content/docs/guides/providers.md, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, tests/providers/codebuddy-live-models.test.ts
Global and CN CodeBuddy entries enable live discovery. Documentation describes account-scoped discovery and degraded static seeds. Test-layout mappings register the new test, which also covers cache isolation and cleanup.

리뷰 · 우선순위 61 / 80

이 PR은 CodeBuddy가 보여줄 모델 이름을, 설치 파일에 적어 둔 목록 대신 codebuddy --help의 "지금 지원하는 모델" 줄에서 읽습니다.

고정 목록은 옛 이름 kimi-k3-1을 남기고, 계정에 있는 kimi-k3-2 같은 새 이름은 빼 둡니다. 모델 목록을 묻는 HTTP 주소는 404라서, 그 도움말 한 줄이 기준이 됩니다. 읽은 결과는 키의 해시로만 구분해서 캐시에 넣습니다. 계정을 바꿔도 이전 계정의 목록을 다시 쓰지 않으려는 장치입니다. CLI가 없거나 줄을 못 읽으면, 그 키의 오래된 캐시를 쓰고, 캐시도 없으면 파일에 적어 둔 목록으로 내려갑니다. codebuddy와 codebuddy-cn은 이 길을 기본으로 켭니다. 베이스는 dev입니다. 드래프트이고 본문 체크리스트는 0/4입니다. #5148은 도구 호출을 받아 적는 PR이라 이 변경과 파일이 겹치지 않습니다.

src/adapters/codebuddy/live-models.ts:36 - 정규식이 영어 문장 전체를 요구합니다. 문장이 바뀌거나 줄 중간에서 끊기면 읽기가 실패합니다. 그러면 경고만 남기고 옛 목록으로 돌아갑니다. 이 PR이 없애려는 상태가 그대로입니다. 테스트는 끊기지 않은 한 줄만 넣습니다.

src/adapters/codebuddy/live-models.ts:94 - 자식은 사용자 홈 폴더를 그대로 받습니다. 81행 주석은 홈을 비우면 목록이 익명용으로 바뀐다고 합니다. 캐시를 구분하는 값은 src/codex/catalog/provider-models.ts:244의 API 키 해시뿐입니다. 홈에 로그인된 계정과 OpenCodex 키가 다르면, 보이는 목록과 캐시에 묶인 키가 어긋납니다. 키가 홈 로그인보다 우선하는지는 이 diff로 확인하지 못했습니다.

src/providers/registry/entries-extended.ts:1320 - 읽기가 성공하면 도움말에 없는 이름은 카탈로그에서 빠집니다. CN 기본 모델은 default입니다. 테스트에 넣은 줄에는 default가 없습니다. 글로벌 기본값 default-model은 1295행입니다. 실제 도움말에도 이 이름이 없으면, 갱신이 성공한 뒤에 기본 모델이 목록에서 사라집니다.

메인테이너의 판단이 필요한 지점
도움말 줄이 넣은 키의 목록인지, 홈에 로그인된 계정의 목록인지는 이 코드만으로 알 수 없습니다. 작성자는 실제 구독으로 카탈로그 갱신을 확인했다고 적었습니다. 끝까지 도는 수락 테스트는 #5148이 같이 들어 있는 참고 브랜치에서 돌렸습니다. 새로 나온 이름은 고정 표에 창 크기와 출력 한도가 없습니다. 이 저장소는 그 숫자를 짐작해 채우지 않습니다.

너의 추천
매칭을 Currently supported: (...)처럼 짧은 표식으로 줄이고, 중간에 줄바꿈이 있는 예문을 테스트에 넣으세요. 프로브 홈을 임시 폴더로 격리하거나, 같은 바이너리에서 키가 로그인보다 우선함을 한 번 보여 주세요. default와 default-model이 도움말 밖에서도 받는 이름이면 유지 목록에 남기세요. 키 두 개의 캐시가 안 섞이는 테스트는 provider-models 쪽에 없습니다. 그것만 추가하면 됩니다. 닫을 중복 PR은 없습니다. 체크리스트는 그 다음에 채우면 됩니다.

추가 리뷰 · 우선순위 34 / 80

지난 리뷰 뒤에 커밋 c0394fd가 들어왔습니다. 그때 적었던 세 가지를 고칩니다.

도움말 정규식은 영어 문장 전체가 아니라 Currently supported: (...)만 봅니다. 앞 문장이 바뀌거나 줄 중간에서 끊겨도 목록을 읽습니다. 테스트에 줄바꿈 예문과, 앞 문장이 바뀐 예문이 있습니다.

기본 모델 이름은 도움말에 없어도 카탈로그에 남습니다. CN은 default, 글로벌은 default-model입니다. 둘 다 호출할 수 있는 이름인데, 도움말 줄에는 빠져 있었습니다.

키 두 개가 캐시를 섞지 않는 테스트도 추가됐습니다. 키 A가 목록을 저장한 뒤 키 B의 읽기가 실패하면, B는 A의 새 목록도 오래된 목록도 받지 않습니다. B는 파일에 적어 둔 default만 받습니다.

홈 폴더는 그대로 둡니다. 작성자가 실제 CLI로 확인했습니다. 틀린 키를 넣어도 이 컴퓨터에 로그인된 계정의 목록이 나옵니다. 홈을 비우면 로그인 없는 목록만 나옵니다. 임시 폴더로 가두면, 이 PR이 없애려는 옛 목록으로 돌아갑니다. 캐시를 나누는 값은 여전히 키의 해시입니다. 그 해시는 다른 키의 저장분을 다시 쓰지 않게 하는 장치입니다. 도움말 줄이 그 키의 목록이라는 뜻은 아닙니다.

PR은 드래프트가 아닙니다. 본문 체크리스트도 채워져 있습니다. 베이스는 dev입니다.

docs-site/src/content/docs/guides/providers.md:811 - 안내 문장은 아직 "지역의 키로 목록을 읽고, 계정을 바꾸면 이전 계정의 목록을 쓰지 않는다"고 합니다. 이번 커밋의 코드 주석은 다릅니다. 키를 틀리게 넣어도 홈에 로그인된 계정의 목록이 나옵니다. 안내와 코드가 다른 말을 합니다.

메인테이너의 판단이 필요한 지점
지난 리뷰의 홈과 키 질문은 작성자의 확인으로 닫혔습니다. 홈을 비우는 쪽은 쓰지 않는 편이 맞습니다. 새로 고를 결정은 없습니다. 안내 문장만 그 확인과 맞으면 됩니다.

너의 추천
811행을 고치세요. 목록은 이 컴퓨터에 로그인된 CodeBuddy 계정의 것입니다. OpenCodex에 넣은 키와 다를 수 있습니다. 캐시만 키의 해시로 나눕니다. 정규식, 기본 모델 유지, 키 두 개 캐시 테스트는 이번 커밋에서 끝냈습니다. 닫을 중복 PR은 없습니다.

추가 리뷰 · 우선순위 16 / 80

지난 리뷰 뒤에 커밋 77dbeeb가 들어왔습니다. 바꾼 곳은 안내 문서 한 줄입니다.

811행은 이제 코드와 같은 말을 합니다. 목록은 이 컴퓨터에 로그인된 CodeBuddy 계정의 것입니다. OpenCodex에 넣은 키와 다를 수 있습니다. 키를 틀리게 넣어도 로그인된 계정의 목록이 나옵니다. 저장은 그 키의 해시로만 묶습니다. 키를 바꾸면 이전 키의 저장분을 다시 쓰지 않습니다. 코드는 이번 커밋에서 안 바뀌었습니다.

docs-site/src/content/docs/guides/providers.md:811 - 같은 문장 끝이 아직 "계정의 오래된 캐시"라고 합니다. 바로 앞은 캐시를 키의 해시로 나눈다고 했습니다. 오래된 캐시도 계정이 아니라 키의 해시입니다. src/codex/catalog/provider-models.ts:244가 그 해시로 읽고 씁니다.

docs-site/src/content/docs/guides/providers.md:811 - 도움말 줄을 기준 목록이라고 합니다. 읽기가 성공해도 default와 default-model은 줄에 없어도 남습니다. 안내는 그 예외를 빼 둡니다.

메인테이너의 판단이 필요한 지점
새로 고를 결정은 없습니다. 동작은 지난 커밋에서 끝났습니다. 같은 줄의 두 곳만 안내가 코드와 아직 다릅니다.

너의 추천
811행 끝의 account-scoped cache를 키 해시 캐시로 고치세요. 도움말 줄이 기준이되, default와 default-model은 줄에 없어도 남는다고 한 줄을 붙이세요. 그 외는 닫아도 됩니다. 닫을 중복 PR은 없습니다.

Review follow-up (260923): the 260923 bundle-round finding — "codebuddy --help returns the roster of whichever account is logged in on the machine… The roster needs to be proven to belong to the key before it is cached" — is addressed at the head (b9bde262d).

Discovery no longer reads --help. It performs GET {canonicalBaseUrl}/v3/config with the configured key as X-API-Key — the same product-configuration endpoint the CLI itself uses — and reads data.agents[].models. The roster is the KEY's own account answer, so the binding the review asked to prove holds by construction: a valid key answers the agent roster (measured live: byte-identical to the CLI's --model list for a signed-in account of that key), while an absent or invalid key answers the anonymous envelope with no agents and no models — there is no roster to misattribute. The CLI binary, its login state, and the caller's home are all irrelevant to the answer now, and the existing key-fingerprint cache scope names the roster's actual authority.

One gateway quirk found while measuring (recorded in the code): the endpoint authenticates the key only behind a CLI/<v> CodeBuddy/<v>-shaped User-Agent (bare axios/fetch UAs get 400 12403 "check ua"); the version value is not validated, so the fixed shape is stable until the vendor tightens it — and a rejection then degrades through the same failure path as any other discovery failure. The branch is rebased onto current dev; the rewritten test suite pins the per-region endpoint, the header set, the anonymous-envelope failure mode, and the cross-key cache isolation.

Maintainer triage: priority: P3 — CodeBuddy roster discovery (#5146).

Criteria (P3): Low: new provider/client integration, large or experimental feature (>2000 LOC or >50 files), RFC/roadmap, or long-stale branch.

Rebased onto current dev: branch rebase/pr-5147 @ 4985a1fa7 (compare). Your fork branch could not be updated directly; you can adopt it with git fetch https://github.com/lidge-jun/opencodex.git rebase/pr-5147 && git reset --hard FETCH_HEAD && git push --force-with-lease. CI was intentionally not run.

The review on lidge-jun#5147 asked for exactly this: the roster cached under the
key's fingerprint must be proven to belong to that key, and a --help
probe can never prove it — the roster it prints is the CLI's signed-in
account, whatever key is configured.

Replace the CLI probe with the product configuration endpoint the CLI
itself uses: GET {canonicalBaseUrl}/v3/config with the configured key
as X-API-Key. The answer IS the key's own account configuration, so the
binding holds by construction.

Measured 260923 against www.codebuddy.cn (CN):
- a valid key answers data.agents[0].models with the same 17 ids the CLI
  prints for --model on a signed-in account of that key (byte-identical),
  plus per-model metadata for the wider account catalog;
- an absent or invalid key answers the anonymous envelope — no agents
  array, empty models — so no roster exists to misattribute;
- the gateway authenticates the key only behind a CLI-shaped User-Agent
  (CLI/<v> CodeBuddy/<v>; bare axios/fetch UAs get 400 12403 "check ua");
  the version value is not validated (CLI/0.0.1 measures fine).

Discovery no longer spawns the CLI, reads the caller's home, or depends
on its login state, so the key-fingerprint cache scope now names the
roster's actual authority. The vendor default selectors and every
degradation path are unchanged; "empty" is now also the wrong-key
signal (the anonymous envelope), which the tests pin.

Reviewed exact head 352461b69b1e3794d6c826130977b54a76f3430a. Moving roster authority from the machine's CLI login to the key-authenticated product configuration endpoint resolves the prior cross-account attribution blocker, and the cache/cooldown fingerprinting is correctly scoped per key. Two current-head blockers remain:

  1. src/adapters/codebuddy/live-models.ts:129-130 calls response.text() before enforcing MAX_CONFIG_BYTES. A malformed or compromised upstream can therefore make discovery retain an arbitrarily large body even though the code advertises a 512 KiB bound. Check Content-Length when present and consume the stream with the repository's bounded-body helper, aborting/cancelling as soon as the limit is crossed. Add a chunked oversized-body regression.
  2. The providers guide was structurally damaged during the rebase: the CodeBuddy Tool Bridge paragraph ends with ordinary answer text.- **Entitlements... on the same line, and the ### Official Qoder CLI (Global & CN) heading was removed, leaving the Qoder section attached to CodeBuddy. Restore the paragraph break, one CodeBuddy Entitlements bullet, and the Qoder heading.

The live roster parser, default-selector retention, per-key fresh/stale cache isolation, and scoped cooldown otherwise match the intended authority boundary.

…face

The provider's static config list drifts from what the CodeBuddy client
actually exposes (stale ids no longer in the roster, new ids missing), and
the HTTP model-discovery URL 404s, so discovery degraded to the stale
configured list. The CLI --model help line prints the current subscription
roster per signed-in account, so fetchCodeBuddyModels spawns the CLI with
the provider key and region env and parses that roster (custom:* selectors
filtered), mirroring the qoder live-models branch: account-scoped cache
identity from the key fingerprint, fresh/stale cache with cooldown, and
fail-closed degradation to the configured list.
The codebuddy and codebuddy-cn registry entries kept liveModels: false, so the CLI --help roster discovery added for these adapters never ran on a fresh install unless the operator flipped the flag by hand. Default both presets to live discovery, document the CLI-roster path in the static-catalog header, and keep the manifest-derived static lists as the degraded seed for installs without a working CLI.
State the discovery authority and failure ladder in the provider guide: the --help roster is account-scoped and server-side (it can differ from the bundled manifest), the cache is bound to an irreversible key fingerprint, and discovery degrades to the account-scoped stale cache and then the static seed.
Review follow-ups on the account-roster discovery PR:

- The roster regex anchored on the full English sentence, so the vendor's
  terminal-width reflow or any wording change silently degraded discovery
  back to the stale list it exists to replace. Anchor on the stable
  "Currently supported: (...)" tail instead and cover wrapped/renamed
  variants in tests.
- The CLI's --help roster is driven by the signed-in home state, not by the
  probe env key (verified live: a deliberately wrong key still prints the
  home account's roster, while an isolated home prints only the anonymous
  floor). Isolation is therefore the wrong fix; document the actual
  authority and keep the key fingerprint as the cache identity, which the
  new catalog-level test pins: key B never observes key A's fresh or stale
  roster.
- A successful live roster omits the vendor default ("default" for CN,
  "default-model" for Global) even though both remain callable selectors, so
  the configured-default retention path now preserves them.
…havior

The guide claimed the roster is read with the region key and framed the fingerprint as account-scoped isolation. The verified behavior (live-models.ts, probed 2026-09-19) is the opposite split: the roster reflects the CodeBuddy account signed in under the caller home and can differ from the configured key — a deliberately wrong key still prints the signed-in account roster — while the cache is what the key fingerprint isolates, so a key switch never observes a roster cached for the previous key. State both halves precisely.
The provider guide called the --help roster "the authoritative model list"
without qualification and did not mention the vendor default selectors.
State that the roster is authoritative for discovered models, that the
default ("default" for CN, "default-model" for Global) selectors never
appear in the roster line but remain callable, and that the catalog retains
them during live discovery and on every fallback path. Rebases onto current
dev.
The CodeBuddy branch called isModelsFetchCoolingDown and
markModelsFetchFailure without the authority identity, so a discovery
failure for one configured key created a provider-wide cooldown: while
another key had its own stale roster, that key's discovery was suppressed
and the stale roster returned without an attempt. Pass the key
fingerprint at both call sites, matching the qoder branch pattern.

Also correct the scope wording: the cache and cooldown are
provider/key-fingerprint-scoped, not account-scoped. The --help roster
reflects the CLI's signed-in account, which the key fingerprint cannot
observe, so the comment and the provider guide now describe the actual
boundary. Regression coverage seeds a stale roster for key B, fails key
A, and proves key B's discovery still runs.
The review on lidge-jun#5147 asked for exactly this: the roster cached under the
key's fingerprint must be proven to belong to that key, and a --help
probe can never prove it — the roster it prints is the CLI's signed-in
account, whatever key is configured.

Replace the CLI probe with the product configuration endpoint the CLI
itself uses: GET {canonicalBaseUrl}/v3/config with the configured key
as X-API-Key. The answer IS the key's own account configuration, so the
binding holds by construction.

…ged guide

Review follow-up (260925, Ingwannu):

1. readBoundedBodyText replaces response.text() in the discovery path: a
   declared Content-Length above the 512 KiB cap is refused before a single
   byte is read, and the stream itself is consumed chunk-wise with the
   repository's bounded-body contract — the reader is cancelled the moment a
   chunk would cross the cap, so a malformed or compromised upstream cannot
   keep discovery reading (or buffering) past the advertised bound. The
   non-200 error-envelope path reads bounded too (4 KiB cap) instead of
   response.json(). Two regressions pin it: a chunked stream that crosses the
   cap mid-read fails as too_large AND cancels the source, and an oversized
   declared Content-Length is refused without reading stream-sized data.

2. The providers guide was structurally damaged during the rebase: the Tool
   Bridge paragraph and the Entitlements bullet had merged onto one line, and
   the Official Qoder CLI (Global & CN) heading had been lost, leaving the
   Qoder section attached to CodeBuddy. Restore the paragraph break, the one
   CodeBuddy Entitlements bullet, and the heading.

Both blockers are addressed at the new head (621dccb64):

  1. Bounded body read. response.text() is gone from both the success and the error path. A declared Content-Length above the 512 KiB cap is refused before a single byte is read (the body is cancelled best-effort), and the stream itself is consumed chunk-wise through a bounded reader that cancels the source the moment a chunk would cross the cap — the same contract as the vision sidecar's bounded error-body read. The non-200 path now reads its error envelope through the same helper with a 4 KiB cap instead of response.json(). Two regressions pin it: a chunked stream crossing the cap mid-read fails as too_large AND cancels the source (the pull count stays chunk-sized, never stream-sized), and an oversized declared Content-Length is refused without stream-sized reads.

  2. Guide structure restored. The Tool Bridge paragraph and the Entitlements bullet are separate lines again, exactly one CodeBuddy Entitlements bullet remains, and the ### Official Qoder CLI (Global & CN) heading is back ahead of the Qoder intro.

Local verification on the head: 16 focused tests pass (the two new regressions included), tsc --noEmit clean, privacy:scan clean, and the live CN gateway still answers the 17-model roster through the bounded reader. The head is rebased onto current dev (zero conflicts) and the readiness checklist is re-completed.
