Read and interaction tool catalogue

The built-in tools

nr-llm ships forty-six read-only tools and twenty-three writing tools. Each is a reference implementation of the security contract: model-chosen arguments are validated and scoped, volumes are capped, and secret-bearing output is either redacted or gated behind a separate _raw variant. Forty ship enabled; the three unredacted _raw variants (get_env_raw, get_php_info_raw and list_be_users_raw), ask_choice, highlight_record, fetch_external_url (see Reading external web pages) and all twenty-three writing tools (update_page_metadata, set_page_social_image, set_file_alternative_text, update_fal_asset_meta, set_file_categories, move_content_element, create_content_element_draft, create_page_draft, create_translation_draft, attach_file_to_content_element, attach_file_to_record, create_record_draft, update_content_element, publish_record, delete_record, copy_record, move_page, replace_file_reference, set_file_reference_alternative_text, create_redirect, update_redirect, disable_redirect, clear_cache) ship disabled and must be enabled deliberately. Many require admin; the read-only structure, content and file tools (get_pagetree, get_tca, get_full_tca, get_table_schema, get_flexform_schema, fluid_resolve, search_records, get_page_content, read_records, get_record_history, resolve_url, validate_tca, list_fal_storages, browse_fal_folder, search_fal_files, get_fal_references, find_missing_files) are offered to non-admin backend users — those self-enforce the acting user's TYPO3 permissions (page-show rights, tables_select) inside the tool, so a non-admin only ever sees what the backend already grants them (see ADR-042). fetch_external_url is offered to non-admins too; it reads public web pages only, which no TYPO3 permission covers, under the controls in Reading external web pages. load_skill is offered to non-admins as well; it brings in only skill text an administrator approved for the run's configuration (see below). ask_choice is offered to non-admins as well; it reads nothing. highlight_record is offered to non-admins as well; it accepts only the record the run is about and the content elements on that page.

In a run started in a draft workspace the tools that read records — get_page_content, read_records, search_records, get_pagetree, read_fal_asset_meta, search_fal_files, get_fal_references, get_record_history, highlight_record and get_tsconfig — read them as that workspace shows them: changed, new, moved, hidden or deleted there as they are there, each record under its live uid, with filters, search terms, limits and offsets applied to what the workspace shows. In live, and in a run that did not record its workspace, they read live rows. A draft of a workspace the run was not started in is never read, and a version row named by its own uid is no record (ADR-260, ADR-263).

The two tools below are the fullest illustrations of the contract:

fetch_logs: Returns the most recent sys_log entries, newest first, with an optional PSR level filter and a limit (default 20, hard-capped at 50). Personally-identifying fields — the client IP, the backend user id and the serialized payload — are redacted by omission, because the result egresses to the external provider.
read_fal_asset_meta: Returns read-only metadata (file name, MIME type, size, title, alternative text) for a single managed file (sys_file) by its uid. The uid is model-chosen and therefore injection-steerable, so the lookup is storage-scoped (default: the default storage). A uid in a non-permitted storage returns the same neutral "not found or not permitted" string as a missing uid — the model cannot enumerate arbitrary files.

The remaining tools follow the same pattern:

list_fal_storages: The file storages this run may touch (uid, name, driver, status flags). The effective set is the configured allow-list, intersected for non-admins with their file mounts; the server-side base path is never part of the output.
browse_fal_folder: One FAL folder: subfolders (with file count), then files with size and MIME type. Storage-relative identifiers only; anything unresolvable collapses into one neutral denial. Capped at 100 entries.
search_fal_files: Substring search over file name and metadata title/alternative within the accessible storages. %/_ in the query match literally; missing files are excluded.
get_fal_references: Where a file is used: sys_file_reference rows as `table:uid (field)`, hidden references marked. Soft references (RTE links, plain URLs) are not tracked — stated in the output so "no references" is never read as "safe to delete". Non-admins only see references from tables they may read.
find_missing_files: sys_file records whose physical file is gone (missing = 1) — the "broken image" diagnosis. The total count is always reported next to the capped listing.
get_env / get_env_raw: Process environment variables. get_env redacts secret-looking values (password, token, key, secret, salt, DSN, …); get_env_raw returns them unredacted (database password, encryption key) and ships disabled.
get_php_info / get_php_info_raw: PHP runtime configuration. get_php_info is redacted; get_php_info_raw returns the full, secret-bearing phpinfo detail and ships disabled.
get_pagetree: The backend page tree (uid, title, doktype) as a depth-indented outline; deleted and hidden pages are excluded — structure only, no content.
get_tca: The TYPO3 TCA schema: with no argument it lists the configured table names; with a table argument it returns that table's field definitions.
list_be_groups: The backend user groups (uid, title).
list_be_users / list_be_users_raw: Backend users. list_be_users omits credentials (password hashes and MFA secrets are never included); list_be_users_raw returns the full non-credential profile columns and ships disabled.
search_records: Full-text search across the record fields the TYPO3 backend search covers. On TYPO3 v13 these are a table's ctrl.searchFields, or every input and text column when the table sets none; on TYPO3 v14 every column of a searchable type whose TCA does not set 'searchable' => false. Returns compact table:uid hits with a short excerpt around the match. Credential and nr-llm configuration tables are never searched; non-admins are limited to their tables_select tables and to hits on pages they may show. With include_hidden the search also returns hidden records, marked (hidden), so an agent can find a draft it created earlier; a non-admin gets them only on pages where they may edit content and with tables_modify on the table.
get_page_content: One page's header data plus its content elements in column/sorting order (uid, colPos, CType, header, a short bodytext excerpt). Non-admins need page-show permission; only admins see hidden elements (marked [hidden]).
read_records: Generic equality-filtered read of one TCA table — never raw SQL. Fields are validated against the TCA and credential-like columns are silently dropped; the same table gates as search_records apply. With include_hidden hidden records are returned too, marked (hidden), under the same edit-permission rule as search_records; deleted records are never returned.
get_record_history: One record's change history from sys_history, newest first: when, which backend user, which action, and per modification the changed fields as old → new values. Values of credential-like fields are never rendered — only the fact that they changed. Same table gates as read_records, and non-admins additionally need page-show access on the record's page.
resolve_url: Map a URL (or path) of this instance to the page that serves it: site, language, page uid/title/slug and route arguments. Routing only — no request is sent; foreign hosts cannot match by construction. Non-admins need page-show permission on the resolved page.
get_typoscript: The resolved frontend TypoScript (setup or constants) effective on a page, with a dotted path drill-down and capped output. Admin-only — constants routinely carry API keys — and credential-like values render as [redacted] on top of that.
get_tsconfig: The rootline-merged Page TSconfig effective on a page, with the same path drill-down, output cap and redaction as get_typoscript. Admin-only.
get_last_exception: The newest exception/error from the TYPO3 file logs with its parsed stack trace and the surrounding source lines of the project frames inlined. index steps back through older errors, search filters by message, class or component. Admin-only. Outside the chat, Error hints asks a model for a cause and next step.
read_source: A line-numbered range of one project source file. Paths must resolve inside the project root; dotfiles, var/* (except var/log), config/system, settings.php/additional.php, key material and credential paths are structurally unreadable. Admin-only.
search_code: Literal-substring (or opt-in regex) search across the project's source files, returning path:line hits. Vendor, var and dot directories are never searched; matched credential lines are value-redacted. Admin-only.
probe_url: One GET against a URL of this instance: status, key headers, timing and a short body excerpt — and on a 5xx the matching exception from the TYPO3 logs is appended automatically. Foreign hosts and non-http(s) schemes are denied; redirects are reported, not followed. Admin-only.
get_full_tca: The TCA index: the names and titles of all accessible tables, each with a pointer to get_table_schema. A navigation aid so the model can traverse the schema without the whole (multi-megabyte) TCA being sent at once. The same table gates as get_table_schema apply. Optional filter and extension narrow the list.
get_table_schema: One table's schema in a readable form: control settings plus, per field, its type and — for relational fields — the foreign table and relation kind (the value over get_tca). Sensitive tables are denied for every user; credential-like columns show name and type only.
get_flexform_schema: The data structure of a TCA FlexForm field, rendered as sheets and fields. When the field selects one of several structures by a pointer, the available keys are listed so a follow-up call can pass ds_pointer. Same table gates as get_table_schema.
fluid_resolve: Which physical Fluid file backs a template, partial or layout name in an extension: the candidate paths in override order with an exists flag and the winning path — to debug a wrong or missing template. Paths only. (Resolves an extension's own Resources/Private paths; TypoScript override root paths need a live rendering context and are not reflected.)
validate_tca: Structural TCA checks: ctrl.label/ctrl.type naming undefined columns, foreign_table references to unknown tables, showitem entries referencing undefined columns or palettes. One table or all accessible tables; findings name schema keys, never record data.
check_typoscript: Scans the TypoScript effective on a page (constants and setup) for syntax errors — invalid lines, unbalanced braces, @import matching no file — using the same core scanner as the backend's TypoScript module. Reports source and line number only, never the offending line's content (a constants line may carry an API key). Admin-only.
list_extensions: The installed (active) extensions: key, version, composer name and title — no package paths. Admin-only.
get_site_config: Without arguments the configured sites (identifier, base, root page); with identifier that site's configuration flattened to dotted key: value lines. Credential-like keys (camelCase included, e.g. apiKey) render as [redacted]. Admin-only.
list_redirects: The redirects of EXT:redirects: uid, source host and path, target, status code and a disabled marker, newest first, at most 100 per call; filters by host or by text in the path or target. QR codes and short URLs of TYPO3 14 are left out. Says so when EXT:redirects is not installed. Admin-only (ADR-257).
list_scheduler_tasks: The scheduler tasks with next execution, disabled flag and a last-run-failed marker. The serialized task object is never unserialized; degrades gracefully when EXT:scheduler is absent. Admin-only.
get_system_status: One compact block: TYPO3/PHP/database versions, application context, composer mode, OS family, timezone — no paths, no hostnames. Admin-only.
list_deprecations: The newest distinct messages from the deprecation log, deduplicated with a ×count suffix and project paths relativized — the upgrade work list. Admin-only.
list_middlewares: A PSR-15 middleware stack (frontend or backend) in execution order with identifiers and classes. Admin-only.
site_rag_query: Curated evidence about the website's own public content for a question: source id, title, URL and match excerpt per source, retrieved from the best available search index — EXT:solr, ke_search, indexed_search or a database fallback — and labelled with the answering backend (ADR-049). Index-level filtering is always public-only (what the anonymous visitor could read).
site_fetch_source: The full indexed text behind a site_rag_query source id, capped at 8000 characters — for reading a promising source beyond its excerpt.
fetch_external_url: One public web page from the internet as readable text: title, headings, main text and links, wrapped as untrusted third-party content. Ships disabled; see Reading external web pages.
ask_choice: Asks the person one question with 2 to 10 short answers given in the call, and suspends the run until one is picked (waiting_for_input, ADR-105). For the choices of a guided process that write nothing — which page, which finding first, whether to continue (ADR-214). The answers form the enum of the input form, shown as a select, and a submission that is not one of them is refused. Typographic spaces in the question and the answers become plain spaces and soft hyphens are dropped; any other invisible character is refused by name. Reads and writes nothing; it never stands in for the approval of a write. Not admin-only. Ships disabled: enable it only where the client handles a run that waits for input — a chat that cannot answer such a pause ends the conversation's run as failed.
highlight_record: Names the record the current point of a guided process is about, so the chat can show the editor where it is (ADR-228). It accepts only the run's subject record — which the runtime checked the acting user may read before the run started — and, when that record is a page, a non-deleted tt_content element on it in the subject's language or in all languages, if the acting user may read tt_content. The run records it as a highlight step holding the table and uid. Writes nothing. Not admin-only. Ships disabled: only a client that renders a highlight can use it.
