Lint and error codes

Lint checks your script before you snapshot or accept an agent edit — undeclared outputs, missing emit labels, bad timeframes, and similar mistakes.

Use this as a lookup when the Code tab or an agent tool reports a rule id or error. Fix the listed issue, re-lint, then save or propose again.

Cross-tier

Symptom / code	Tier	Fix
Undeclared output / result id	All	Declare before emit/publish
Module-level bar state	Indicator / definition	Use `ctx.accum`
Bad timeframe argument	Indicator / definition	Literal or `input.timeframe` → `ctx.params`
Dependency empty / unavailable	All	Guard or fix declare
Budget / timeout	All	Trim work — Budgets

Rule / symptom	Severity	Fix
`events/emit-missing-label`	warn (+ runtime drop)	Pass non-empty `opts.label` on `ctx.emit`
Unknown event id	error / drop	`events.declare` the id
Reserved `_displayLabel` in payload schema	error	Remove — set via emit label
Hand-rolled emit dedupe	smell	Use `oncePer`

API	When	Fix
`ctx.mark`	`labelMode` always/onHover without `text`	Pass `text`
`ctx.range`	`labelMode === "always"` without `label`	Pass `label`
`ctx.note`	missing `price`	Pass `price`

Symptom	Fix
Publish undeclared result	`results.declare`
`pin_cell` wrong kind	`kind: "popover_layout"`
`missing_accepted_mockup`	Accept mockup before rewrite
Dim mismatch on cells	Align `dims` with `indexedBy`
