Document reserved import property names and large-import page sizing

[clarkd]

📋 Summary

This PR adds two pieces of build-plugin guidance that customers have recently had to learn the hard way.

Reserved property names. A plugin that maps id, state or an internal __ name in objectMapping.properties deploys cleanly, then every import fails with a raw graph error ("boolean schema is false" at /vertices/0/id) that never mentions the mapping. Credit Acceptance hit this building an Entra ID plugin (Zendesk 32676). index-defs.md now lists the names that fail, the ones the platform silently overwrites, and the errors each produces, with renames to use instead. REVIEW.md gets the matching rule.

Large imports. CoPA's CrowdStrike import (~92,700 hosts) overflowed the ~6MB per-page limit at 1,000 hosts per page, and smaller pages would have hit the ~220 call cap per import run. The skill also said SquaredUp "supports as many paged requests as needed", which isn't true. There's a new section in index-defs.md on sizing pageSize against both limits, keeping import rows lean, and importing less when nothing fits. Phase 1 now asks for an object-count estimate, and checkpoints.md decodes the raw errors these limits produce.

The docs say squaredup validate rejects reserved names. That's only true once squaredup/saas#10107 (SAAS-10256) ships, so this should merge after it.

Summary by CodeRabbit

• Documentation
  • Clarified approximate import limits of 220 pages per run and 6 MB per page, plus per-page timeouts and guidance for choosing page sizes in larger environments.
  • Added troubleshooting guidance for import errors caused by oversized pages, too many pages, and reserved property names.
  • Documented which property names may fail validation or be overwritten, and how to keep imports within response-size and call-chain limits.

📝 Walkthrough

Plugin documentation now describes reserved objectMapping.properties names, their validation or overwrite behavior, and import page-size limits. Troubleshooting guidance links schema errors and import size or call-chain errors to these constraints.

Changes: Plugin import guidance

Layer / File(s)	Summary
Import page-size limits .claude/skills/build-plugin/SKILL.md, .claude/skills/build-plugin/references/checkpoints.md, .claude/skills/build-plugin/references/index-defs.md	The guidance describes approximate per-page response, per-page timeout, and per-import call-chain limits. It recommends sizing pages for the largest environment and links the corresponding troubleshooting errors to the page-size guidance.
Reserved mapping properties .claude/skills/build-plugin/references/index-defs.md, REVIEW.md	The guidance identifies property names that are rejected, fail schema validation, or are overwritten. It notes which names remain usable as source columns and which squaredup validate catches.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 581f5

The review rule may prompt unnecessary changes to valid platform-state mappings. Qualify the restriction by value; otherwise, the documentation change presents low merge risk.

Before / after behavior

• observed — Modified behavior in REVIEW.md: Added source-type guidance: do not use id, state, or __-prefixed property names; rawId, sourceId, sourceType, name, and label are overwritten. For large-tenant APIs, check pageSize against the ~6 MB per-page and ~220-page-per-run import limits.
• observed — Modified behavior in .claude/skills/build-plugin/references/checkpoints.md: The existing guidance to inspect JSON import status and per-step details now adds three error-to-cause mappings: schema validation errors at /vertices/N/<prop> indicate reserved mapped property names; Function.ResponseSizeTooLarge indicates a page over approximately 6 MB; and the call-chain threshold of 220 indicates too many pages. The last two cases link to the page-size guidance.
• observed — Modified behavior in .claude/skills/build-plugin/references/index-defs.md: Added reserved property-name guidance: id and __-prefixed names are rejected, state values fail schema validation, and rawId, sourceId, sourceType, name, and label are silently overwritten. Reserved names remain usable as source columns; validation rejects only id, state, and __ names.
• observed — Modified behavior in .claude/skills/build-plugin/references/index-defs.md: Added import pageSize guidance covering the approximate 6 MB per-page response limit, 220-call import-chain limit, and 28-second per-page timeout. It describes sizing pages for the largest environment, targeting fewer than roughly 200 calls and under 2 MB of raw response, keeping import rows lean, and filtering or importing a subset if no page size fits both constraints.

Qualify the state restriction by value.

index-defs.md states that state fails only when its value is outside the platform's allowed values. This rule says every state target fails, which can cause valid platform-state mappings to be rejected or renamed unnecessarily.

Suggested fix

-objectMapping.properties - Never use `id`, `state`, or a `__`-prefixed name as a property name; they fail the import at graph write. Rename instead, e.g. `{ "status": "state" }`. `rawId`, `sourceId`, `sourceType`, `name` and `label` are silently overwritten, so mapping them does nothing.
+objectMapping.properties - Never use `id` or a `__`-prefixed name as a property name; they fail the import at graph write. `state` fails only when its value is outside the platform's allowed values. Use a different target for API status or postal-state data, e.g. `{ "status": "state" }`. `rawId`, `sourceId`, `sourceType`, `name` and `label` are silently overwritten, so mapping them does nothing.

@coderabbitai Re the outside-diff comment on REVIEW.md:107 (qualify the state restriction by value): skipping this one as intentional. squaredup validate rejects state as a property name whatever its value (see index-defs.md: "squaredup validate rejects id, state and __ names"), so a plugin mapping state fails CI before it ever reaches graph write. The "allowed values" error is just what you see if a mapping gets past validation, so "never use state" is the right rule for reviewers.

@clarkd Thanks for clarifying. index-defs.md confirms that squaredup validate rejects state as a property name regardless of its value. The reviewer rule should remain unconditional. I withdraw the suggestion to qualify it by value.

Timestamp: 2026-10-14T19:20:05.065Z
Learning: In squaredup/plugins, REVIEW.md and .claude/skills/build-plugin/references/index-defs.md intentionally prohibit state as a target property name in objectMapping.properties, regardless of its value. As clarified by the author, squaredup validate rejects that name before graph write once the validator change ships. Graph-write allowed-values errors do not justify weakening the reviewer rule. A source column named state is valid when mapped to a different target property, such as { "status": "state" }.
