ELI5

When the jobs and assets API tells you you're sending requests too fast, the SDK already raised the right "rate limited" error, but only by luck: it fell through one lookup into a second one. This change writes that link down on purpose, next to the three other errors that work the same way, and fixes the docs that still said there were three. Nothing about which error you get changes.

What changed

• src/comfy_sdk/exceptions.py: "rate_limited": RateLimited added to _BY_CODE (next to insufficient_credits), RateLimited imported from .router_exceptions and added to __all__ (sorted) as the other shared classes are. The _BY_CODE comment, _class_for step 1, the to_sdk_error comment and the __all__ comment now say four, and the _BY_CODE comment says why: the v2 contract's account rate limit (components/responses/RateLimited) and Router's rate_limited bucket are the same windowed allowance spelled the same way, so one class serves both and .error_type == "rate_limited" is set from either surface.
• src/comfy_sdk/router_exceptions.py: module docstring names four shared buckets including rate_limited; RateLimited's docstring keeps the Router meaning and the ConcurrencyLimitExceeded contrast, adds the v2 jobs/assets use, and narrows "detail names the window" to the Router surface. _spec_meaning_digest untouched (it hashes the Router spec's meaning, not this docstring; test_router_spec_contract.py and check_drift.py both pass).
• README.md: the shared-names paragraph lists four and says a jobs/assets call throttled with 429 rate_limited raises RateLimited; the "never reached Router → plain ComfyError" sentence gets a clause for responses that land on one of the four shared codes — a v2 envelope naming one, or a bare 401/402/403 the status table maps to one — so except RouterError firing is not by itself proof Router answered.
• tests/test_error_mapping.py: rate_limited added to test_a_bucket_both_surfaces_spell_keeps_its_v2_class; new test_a_v2_envelope_rate_limited_is_the_shared_router_class (no error_type, asserts exact type, RouterError ancestry, code, error_type, retry_after), with a comment marking the sharing as deliberate.
• CHANGELOG.md: one bullet in Unreleased's existing ### Changed section.

Judgment calls

• Package root left alone. comfy_sdk re-exports Unauthorized/Forbidden/InsufficientCredits at the root, but its own comment says per-bucket Router classes stay in comfy_sdk.router_exceptions; adding comfy_sdk.RateLimited would be new public surface, which is out of scope. The README says so explicitly ("and the first three by comfy_sdk too").
• rate_limited removed from test_a_router_only_bucket_raises_its_typed_class. It's no longer a Router-only bucket, so leaving it there would make that test's name wrong. Its assertions (exact type, code, http_status, retry_after == 7 at 429) are all covered again by the new test, so no coverage is lost.
• CHANGELOG placement: the entry sits in Unreleased's existing ### Changed section rather than a second heading. It also mentions the new comfy_sdk.exceptions.RateLimited re-export.

Residual

• tests/test_head_refusal.py and the HEAD /assets/by-hash 429 synthesis belong to open PR fix(assets): read a bodiless HEAD 429 on the by-hash probe as rate_limited, not queue_full #208 and weren't touched or run here (that file doesn't exist on main). When fix(assets): read a bodiless HEAD 429 on the by-hash probe as rate_limited, not queue_full #208 lands, its type(exc) is RateLimited assertion now resolves through _BY_CODE instead of the fall-through. Same class, so no change is expected.
• Open PRs feat(errors): map sso_required to Forbidden and carry organization_id #205 and feat(errors): add a typed AssetInUse so a delete conflict is catchable #151 also add _BY_CODE lines. Expect a trivial merge conflict on adjacent dict lines, nothing semantic.
• No behavior change, so no mutation test can tell this PR apart from main: removing the new _BY_CODE entry still passes because the fall-through gives the same class. The proof that behavior didn't change is that tests/test_job_metadata.py (which already pins v2 rate_limited → RateLimited) passes unmodified.
• tests/integration/test_gateway_e2e.py skips without live credentials, so it wasn't exercised.

Provenance

• Authored by: agent-work loop
• Verified:
  • Tests: full suite green locally on the current head (e6220d5): 1276 passed, 9 skipped (the skips include the credential-gated gateway e2e)
  • Lint/format/types: ruff check, ruff format --check, mypy src all clean on the current head
  • Public-repo hygiene script: clean
  • CI on the current head: Test matrix (3.10–3.13), build-check, codegen drift and public-repo-hygiene all pass
  • README carve-out checked against comfy_low.errors._CODE_BY_STATUS (401/402/403 map to the shared codes; 429 maps to queue_full, not rate_limited)
• Deviations: none from acceptance. The root-export and test-reshuffle choices are listed under Judgment calls.

Summary by CodeRabbit

• New Features
  • Added a shared RateLimited exception for rate-limit errors across account, workflow, jobs, and assets calls. These errors can include retry timing information.
  • Documented when authentication, credit, and rate-limit errors are reported through the Router error hierarchy.

Walkthrough

The v2 error-code mapping now resolves rate_limited to the shared Router RateLimited class. The class is exported from comfy_sdk.exceptions. Tests and documentation cover the mapping and shared behavior.

Changes: Shared Rate-Limit Exception Mapping

Layer / File(s)	Summary
Map and export the shared rate-limit exception src/comfy_sdk/exceptions.py, src/comfy_sdk/router_exceptions.py, tests/test_error_mapping.py, README.md, CHANGELOG.md	The rate_limited code maps to the shared RateLimited class, which is exported from comfy_sdk.exceptions. Tests verify mapping by code and preservation of retry_after. Documentation describes the shared exception behavior.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 3 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
