Stacked on #118 (base: work/dc/skill-correlation) — review that one first.

Why

#118 teaches the skill to author correlation rules. It cannot check them. Every verification path the skill describes is a dead end or a hand-off:

The CLI has no edge-query command, so confirm in the tenant — ask the user to open an object of the source type and check its relationships — or use the SquaredUp MCP server's graph_query if one is connected.

So the agent ships rules it cannot test, and a rule that validates but matches nothing looks exactly like one that works. squaredup 1.1.0 adds edges, correlate and correlate-status, which close that loop.

What changes

Checkpoint B step 5 now drives the confirmation itself instead of handing off to the UI:

  • correlate-status --datasource-id <id> --json — which rules installed, and what each one did.
  • edges --datasource-id <id> --plugin-id <pluginId> --json — the edges they produced. --rule <ruleName> narrows to one.

Three ideas the skill did not previously have:

  1. The rule list is the install check. A correlationRules/*.json that doesn't appear in correlate-status never deployed. validate only proves the file parses — the skill treated that as sufficient.
  2. Read per rule, not the top-level flags. succeeded: true means every rule ran, not that any matched. edgesCreated: 0 with a healthy verticesProcessed is a rule bug, and it names which rule to fix. Previously "zero edges" was an undifferentiated dead end.
  3. An iteration loop that doesn't need a re-index. Correlation normally only runs after an import, but correlate re-runs it on demand, so fixing a rule costs a redeploy rather than a full re-index. The exception is a new join key — that still needs an import, because existing objects lack the property.

Also: Prerequisites note the 1.1.0 floor and that correlate needs a tenant admin (the two read commands don't, so a non-admin can still verify); two rows of the common-mistakes table name the diagnostic that reveals them rather than just the symptom; and REVIEW.md asks for evidence that edges were confirmed, since nothing in CI can check a rule matched anything.

Notes for review

  • Depends on the CLI release. These commands are on squaredup/plugins-cli#42, not yet published — npm i -g @squaredup/cli currently installs 1.0.1, which has none of them. Merge this after that ships, or the skill will tell agents to run commands that don't exist.
  • Docs only, no plugin directories touched, so Validate & Deploy Plugins has nothing to do here.
  • The commands and their JSON shapes were exercised end-to-end against a real tenant while building them (12 Cloudflare rules, 37 edges), so the examples are real output rather than invented.

Summary by CodeRabbit

  • Documentation
    • Added CLI-based guidance for verifying correlation rules after imports.
    • Documented correlation status polling, edge inspection, on-demand correlation, and zero-match troubleshooting.
    • Clarified permissions and required identifiers for correlation commands.
    • Added a guideline requiring real-data evidence that new rules create expected relationships.

The skill could author correlation rules but not check them. Every verification
path it described was a dead end or a hand-off: "the CLI has no edge-query
command", confirm in the tenant UI, or use the MCP server's graph_query if one
happens to be connected. So the agent shipped rules it could not test, and a
rule that validated but matched nothing looked identical to one that worked.

squaredup 1.1.0 adds edges, correlate and correlate-status, which close that
loop. This teaches the skill to use them:

- Checkpoint B step 5 now drives the confirmation itself — correlate-status for
  which rules installed and what each one did, then edges for what they
  actually related. Replaces the UI hand-off.
- The rule list from correlate-status is called out as the check that rules
  installed at all; validate only proves a file parses.
- Read per rule, not just the top-level flags: succeeded means every rule ran,
  not that any matched. edgesCreated: 0 with a healthy verticesProcessed is a
  rule bug, and it names which rule to fix.
- correlation-rules.md gains an iteration loop. Correlation normally only runs
  after an import, but correlate re-runs it on demand, so fixing a rule costs a
  redeploy rather than a full re-index — the exception being a new join key,
  which does need one because existing objects lack the property.
- Prerequisites note the 1.1.0 floor, and that correlate needs a tenant admin
  while the two read commands do not, so a non-admin can still verify.
- Two rows of the common-mistakes table now name the diagnostic that reveals
  them rather than just the symptom.
- REVIEW.md asks for evidence that edges were confirmed; nothing in CI can.

In @.claude/skills/build-plugin/references/checkpoints.md:
- Around line 83-86: Bound correlation polling to a finite timeout and do not
treat correlate-status.done as sufficient readiness because it may describe a
previous run. In the correlation workflow, use the current run’s edgesCreated
value to stop when it reaches zero; otherwise continue polling edges within the
timeout, preserving the existing datasource-scoped correlate-status and
plugin-scoped edges requirements.

In @.claude/skills/build-plugin/references/correlation-rules.md:
- Line 283: Update the re-indexing guidance in the correlation loop section to
require the full Checkpoint B cycle whenever an imported-object shape changes,
including indexDefinitions/*.json or import-stream changes to join-key mappings,
id, name, or type. Retain the no-re-index exception only when the imported
object shape is unchanged.

In @.claude/skills/build-plugin/SKILL.md:
- Line 309: Update the zero-edge diagnostics guidance so edgesCreated: 0 prompts
investigation but does not prove a join-key or type mismatch, and explicitly
allow valid no-match results when the test tenant lacks a matching relationship.
In .claude/skills/build-plugin/SKILL.md lines 309-309, revise the rule-problem
wording accordingly; in
.claude/skills/build-plugin/references/correlation-rules.md lines 274-274,
replace “which is a rule bug” with equivalent conditional wording.
- Around line 305-309: Update the Phase 5b correlation confirmation flow to use
a defined retry interval and maximum wait, polling correlate-status until
completion or timeout. Treat timeout, run-level succeeded=false, and any failed
rule status as failures; report the run-level and per-rule errors and do not
invoke squaredup edges when any failure occurs.

In `@REVIEW.md`:
- Line 110: Update the two evidence commands in the review guidance for rule
validation—squaredup correlate-status and squaredup edges—to include
--datasource-id, --plugin-id, and --json, while preserving the existing
rule-specific arguments and purpose.

Four of CodeRabbit's five findings on #121 were right, and the first one was
right for a reason it didn't have: `correlate-status` DOES take `--since` (an
exclusive `lastEvaluated` anchor, exactly like `index-status --since` on
`scheduledStart`) — the skill just never mentioned it. Without it `done: true`
can describe the *previous* import's correlation, so a rule that matched last
time reads as a pass before this run has started. Documented the anchor, where
to get it (a pre-import `correlate-status`, or `correlate --no-wait --json`),
and why the `since` from `index` is NOT a substitute: it is the previous
import's start, which the previous correlation run already cleared.

Also from the review:

- Bound the poll — ~5s interval, give up after ~5 minutes, mirroring the CLI's
  own `correlate` (5s polls, 600s default). A timeout is not a failure, but it
  is not a confirmation either: report unconfirmed rather than reading whatever
  `edges` happens to hold.
- Branch on failure before reading edges — `succeeded: false` or a rule with
  `status: "failed"` means report `ruleName`/`status`/`errorCount` and fix that
  first. Added the states an agent will actually meet: `succeeded: null` while
  in flight, `notRun`, and `warnings` (succeeded, but check `errorCount`).
- `edgesCreated: 0` is no longer stated as a rule bug. It usually is, but a
  correct rule reports zero against data with nothing to relate — the CLI's own
  smoke test hit exactly that, an object-group rule creating 11 edges on dev and
  0 on us/eu. So: check the join keys pair up before rewriting the rule.
- The no-re-index claim now turns on the imported objects being unchanged, not
  narrowly on adding a join key. Any `indexDefinitions`/import-stream edit —
  changing an existing mapping, `id`, `name`, `type` — leaves them stale, which
  is what the re-indexing rule already said.

Not taken: expanding the REVIEW.md evidence bullet to full `--datasource-id
--plugin-id --json` invocations. That file tells a human reviewer what evidence
to expect in a PR; the runnable forms live in correlation-rules.md, and no other
bullet in REVIEW.md carries flags.

Field names and semantics verified against the CLI source on
squaredup/plugins-cli `work/dc/saas-9814-edges-command`, and the `--since` /
`--timeout` flags against the installed 1.1.0 binary.
