Append Raw Source Rows

openl_append_table

Add raw source rows to an existing table to expand its data. Each row must cover every column, using null for blank cells; rows with the wrong width are rejected before any write occurs.

Instructions

Append RawSource rows to an existing table. Typed append DTOs are intentionally unsupported. Every row must cover ALL columns of the table; wrong-width rows are rejected before anything is written. Use { value: null } for a blank cell and preserve covered placeholders for merged regions. For modifying or reordering use a narrow raw action tool or update_table; remove rows/columns only with the corresponding delete action. The response returns the CURRENT tableId after relocation, and the read-back triggers recompilation.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
tableIdYesTable identifier - unique ID assigned by OpenL Studio (e.g., 'calculatePremium_1234'). VOLATILE: derived from the table's location, so it changes when an edit relocates the table (it had no room to grow in place) — use the 'tableId' returned by the latest openl_update_table/openl_append_table response, or refresh via openl_list_tables().
projectIdYesProject ID returned by backend. Use the exact 'projectId' value from openl_list_projects() response without modification or reformatting.
appendDataYesRawSource append payload. Typed table append DTOs are intentionally unsupported because they are lossy and incomplete.
response_formatNoResponse format: 'json' for structured, round-trippable data (default), 'markdown' for human-readable output, 'markdown_concise' for a brief summary (1-2 paragraphs), or 'markdown_detailed' for full details with contextjson

    • addedInput schema / properties / appendData / additionalProperties
      Added value: +false
    • changedInput schema / properties / appendData / description
      Previous value: -"Data structure to append to the table. Structure depends on tableType: Datatype uses 'fields'; SimpleRules/SmartRules use 'rules'; SimpleLookup/SmartLookup use 'rows' (array of maps); Data/Test use 'rows' (array of { values }); SimpleSpreadsheet uses 'steps'; Spreadsheet uses 'rows' (row headers) + 'cells' (2D cell array); Vocabulary uses 'values'; RawSource uses 'rows' (array of cell-arrays)."New value: +"RawSource append payload.

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only carry openWorldHint, so the description carries the burden of behavioral disclosure. It discloses that wrong-width rows are rejected before anything is written, that the response returns the CURRENT tableId after relocation, and that read-back triggers recompilation. It does not mention permission requirements or error behavior, but the provided side-effect details are valuable and non-obvious.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is four sentences and every sentence carries distinct information: scope, unsupported DTOs, width constraint, blank-cell encoding, alternative routing, and response side effects. It is dense but not bloated, and the core purpose is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a nested-payload tool with no output schema, the description covers the critical behavioral contract: rejection atomicity, merged-region handling, tableId volatility, and recompilation. Combined with the fully described input schema, it gives an agent enough to invoke the tool correctly, though the exact full response shape is not specified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds meaningful semantic guidance beyond the schema: the all-columns width requirement, the '{ value: null }' blank-cell encoding, and the instruction to preserve covered placeholders for merged regions. These details help the agent construct correct appendData payloads.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with 'Append RawSource rows to an existing table', a specific verb plus resource, and immediately distinguishes itself from typed append DTOs and sibling actions like update_table and delete actions. The scope is precise and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly states when to use this tool (appending raw rows) and when not to: 'For modifying or reordering use a narrow raw action tool or update_table; remove rows/columns only with the corresponding delete action.' This directly routes the agent away from inappropriate sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
