Task fields 

Input sources 

The input_type selects how automatic task input is resolved. input_source stores JSON options for sources that support them:

manual

The run form supplies input. input_source has no effect.

syslog

Reads sys_log from newest to oldest. Use limit (default 50) and error_only (default true). For example: {"limit":100,"error_only":true}.

table

Reads rows from the configured table with limit (default 50). For example: {"table":"sys_log","limit":100}. The record-picker exclusion policy applies. The editor list and form do not offer table tasks; the record-picker endpoints require administrator rights. A where option does not apply a SQL filter.

deprecation_log

Reads the last 100 lines from var/log/typo3_deprecations.log. input_source has no effect.

file

A reserved persisted value retained for compatibility. It has no reader or established source schema and currently produces empty automatic input. Paths, URLs and file identifiers in input_source are ignored. Supply text through manual input when a task needs file contents.

Use a positive limit for syslog and table sources. Numeric strings are converted to integers. Unrecognised JSON options are ignored; invalid JSON falls back to the source defaults.

Deprecation-log input 

The deprecation_log input type reads the tail of TYPO3's deprecation log. A missing or unreadable log produces a localized placeholder. A reader failure also preserves this best-effort behavior: the original cause and task context are passed to diagnostic logging, while the task input receives the generic read-error placeholder rather than private paths or exception details. If diagnostic logging itself fails, the placeholder is preserved. The same diagnostic containment applies to failed syslog and table reads, including record-picker policy rejection.

Placements 

placements (Offered first in) marks the places where a task is listed first, in a group of its own. nr-llm declares one place:

ai_tasks

The editors' module AI tasks. Marked tasks appear under Prepared for this module; a task marked for no place follows under its category, and a task marked for other places only is not listed there.

Other extensions add their own places to the same field. nr-landingpage, for example, adds Landing page: image prompt for the template field that switches on image generation. A place decides whether it shows the unmarked tasks after the marked ones or hides them; a place that hides them still shows the task a record already holds, and shows every task while none is marked for it. ADR-245 records the decision.

An extension that offers tasks in a TCA select names its place and lets nr-llm order the items:

$GLOBALS['TCA']['tx_nrllm_task']['columns']['placements']['config']['items'][] = [
    'label' => 'LLL:EXT:my_ext/Resources/Private/Language/locallang_db.xlf:placement',
    'value' => 'my_ext_place',
];

'config' => [
    'type' => 'select',
    'renderType' => 'selectSingle',
    'foreign_table' => 'tx_nrllm_task',
    'itemsProcFunc' => \Netresearch\NrLlm\Form\Tca\TaskPlacementItems::class . '->groupByPlacement',
    'itemsProcConfig' => ['placement' => 'my_ext_place', 'unmarked' => 'hide'],
    'itemGroups' => [
        'nrllm_placement' => 'LLL:EXT:nr_llm/Resources/Private/Language/locallang_tca.xlf:tx_nrllm_task.placements.group.marked',
        'nrllm_unmarked' => 'LLL:EXT:nr_llm/Resources/Private/Language/locallang_tca.xlf:tx_nrllm_task.placements.group.unmarked',
    ],
],

unmarked is after (default) or hide. Code that reads task records itself asks Task::isPlacedIn().
