Verdict: APPROVED

Re-review of board item #1914 after refinement. Prior review review-1914-2026-07-25 returned NEEDS_REFINEMENT with two findings. Both addressed.

Refinement Resolution

  • [LABEL] arch:api to arch:domain-postmark -- FIXED. Board item #1914 now carries arch:domain-postmark. Verified via fresh board pull.
  • [DECOMPOSE] Decomposition waived -- ACCEPTED. This is intentionally an 8-point ticket for agent-driven implementation where a dev agent implements the full SDK in one pass. The repo's docs/acceptance-criteria.md provides a detailed endpoint-to-test mapping (43 endpoints across 7 groups) that serves as the agent's implementation guide. Decomposition would add overhead without benefit for single-agent execution.

Template Completeness

  • [x] Type -- Feature
  • [x] Lineage -- Blocked by #1 (docs PR), Sprint 2
  • [x] Repo -- ldraney/postmark-server-sdk
  • [x] User Story -- well-formed (developer wants pytest coverage of every endpoint)
  • [x] Context -- references swagger spec, forgejo-sdk pattern, token source
  • [x] File Targets -- 10 files/directories listed
  • [x] Feature Flag -- none (appropriate for SDK infrastructure)
  • [x] Acceptance Criteria -- 5 criteria, supplemented by docs/acceptance-criteria.md
  • [x] Test Expectations -- pytest command specified, real API (no mocks)
  • [x] Constraints -- forgejo-sdk patterns, uv/pyproject.toml
  • [x] Checklist -- present
  • [x] Related -- present

Traceability

  • [x] story:sdk label -- Postmark SDK Foundation
  • [x] story note verified -- story-postmark-sdk exists in postmark-project-page user-stories section (key: sdk, metric: 100% endpoint coverage in pytest)
  • [x] arch:domain-postmark label -- corrected from prior review
  • [x] arch note verified -- arch-domain-postmark note exists in pal-e-docs (architecture type, active tag, ER diagram covering PostmarkServerSDK entities)
  • [x] Forgejo issue -- ldraney/postmark-server-sdk#2, state: open

File Targets

  • [x] pyproject.toml -- to create. No conflict with existing repo contents (CLAUDE.md, README.md, docs/, swagger spec).
  • [x] src/postmark_server_sdk/ -- to create. Note: issue body uses postmark_server_sdk but docs/acceptance-criteria.md uses postmark_sdk. See recommendation.
  • [x] tests/conftest.py -- to create. Token loading from POSTMARK_SERVER_TOKEN env var.
  • [x] tests/test_sending.py -- to create. 4 endpoints (send, batch, template, batch-template).
  • [x] tests/test_bounces.py -- to create. 5 endpoints.
  • [x] tests/test_messages.py -- to create. 11 endpoints (7 outbound + 4 inbound).
  • [x] tests/test_templates.py -- to create. 6 endpoints (CRUD + validate).
  • [x] tests/test_stats.py -- to create. 12 endpoints across outbound stats.
  • [x] tests/test_server.py -- to create. 2 endpoints (get/edit config).
  • [x] tests/test_inbound.py -- to create. Note: issue says test_inbound.py but acceptance-criteria.md says test_inbound_rules.py. See recommendation.
All targets are new files -- Sprint 1 (docs PR, #1910) is in done. No existing files to verify against.

Repo Placement

OK. Issue filed on ldraney/postmark-server-sdk, all work targets the same repo. No cross-repo concerns.

Dependencies

  • Blocked by: ldraney/postmark-server-sdk#1 (docs PR) -- RESOLVED. Board item #1910 is in done column.
  • Sibling: Board item #1915 "Sprint 2: SDK implementation -- postmark-account-sdk" is in backlog with same labels. Independent -- can run in parallel.
  • Downstream: Sprint 3 MCP items (#1918 postmark-server-mcp, #1919 postmark-account-mcp) depend on SDK packages being installable. No blocking concern for this sprint.

Acceptance Criteria

5 criteria in the issue body, all agent-verifiable:
  • "Every endpoint in postmark-server-api.yaml has at least one test" -- verifiable by counting endpoints (43 per acceptance-criteria.md, 41 operationIds in swagger -- close enough, likely minor counting difference)
  • "All tests pass against the real Postmark API" -- verifiable via pytest tests/ -v
  • "SDK client handles auth via POSTMARK_SERVER_TOKEN env var" -- verifiable by code inspection
  • "Error responses are handled gracefully" -- verifiable but slightly vague (minor concern, carried from prior review)
  • "Tests are organized by API group matching the swagger spec sections" -- verifiable by file structure
The docs/acceptance-criteria.md provides a detailed 7-section completion checklist plus per-endpoint test expectations for each group. This compensates for the issue body's higher-level AC.

Blast Radius

Sibling repo postmark-account-sdk (#1915) follows the identical pattern. Both SDKs will be pip-installed by MCP repos in Sprint 3. No downstream consumers exist yet. The arch:domain-postmark label fix applied to #1914 was also applied to #1915.

Decomposition Assessment

  • File targets: 10+ files in 1 repo (single-repo, no multi-repo trigger)
  • Acceptance criteria: 5 in issue body (under threshold)
  • Estimated agent work: 43 endpoints, ~45 minutes. Exceeds 5-minute rule.
  • Waived. Caller explicitly states this is intentionally a large ticket (8 points) designed for agent-driven implementation in one pass. The docs/acceptance-criteria.md in the repo provides the detailed endpoint-to-test mapping that guides the dev agent. Decomposition would fragment the work without benefit.

Recommendation

Minor [BODY] items -- non-blocking, can be fixed during implementation or before:
  • [BODY] Align package directory name: issue body says src/postmark_server_sdk/, docs/acceptance-criteria.md says src/postmark_sdk/. Pick one and update the other. Recommend postmark_server_sdk to match repo name and distinguish from account SDK.
  • [BODY] Align test file name: issue body says tests/test_inbound.py, acceptance-criteria.md says tests/test_inbound_rules.py. Recommend test_inbound_rules.py to match the source module name inbound_rules.py.
  • [BODY] Acceptance-criteria.md completion checklist item 7 references Woodpecker CI (issue #3), which is Sprint 3 scope. Consider removing or marking as out-of-scope for this ticket.
None of these block implementation. The dev agent should follow docs/acceptance-criteria.md as the authoritative source for file names and endpoint mappings.
