check_patchesDoes each composer patch still apply to the release the site installed, and is its fix already in that release? - Send composer_json and composer_lock after composer update. Add patch_files for every patch, a local one read from disk and a URL one fetched by you. Every extra.pat…
describe_datasetLearn the dataset before writing SQL for query_dataset. Call it with no arguments first. Returns text. Prefer a typed tool when one answers the question. - No arguments: one line per view, the join map, the four invariants, the causes of empty results, and the recipe index. The…
get_change_recordReturn one core change record in full: title, flavour, target version, machine-checkable tracks, linked issues, linked core symbols, and contrib adoption counts. To find records, use list_change_records or the change_record_nids from what_changed. For one symbol's detail, use lo…
list_change_recordsList the core change records (the human write-ups) that target a range of core versions, tagged by flavour and ranked, with counts. For the symbol-level diff, use what_changed. For one record in full, use get_change_record. - Bounds are inclusive. Forms: 11.2, 11.2.x, 11.2.0, 11…
list_class_relationsList the contrib classes that extend, implement or use a core class, interface or trait, one row per edge with file and line, paged. Example: "who subclasses FormBase". Call-site counts: list_symbol_users. The symbol's status: lookup_core_symbol. - target: with or without the le…
list_projectsList drupal.org projects after filters, largest install base first, paged. Examples: "top modules without an 11.4 branch", "themes over 10k installs without security coverage". One project: project_profile. Its pending records: project_upgrade_report. - Filters combine: type, mi…
list_symbol_usersList every contrib project using one core symbol, or any symbol in a class of symbols, one row per project, paged, with the matched symbols. lookup_core_symbol answers one symbol with a head of 30. - Pass fqn, or filters: kind, status (deprecated, scheduled_removal, removed), su…
lookup_core_symbolAnswer "is this core symbol safe to use, and who still uses it" for one symbol. A name that resolves to nothing returns the catalog entries containing it instead. Every user in pages: list_symbol_users. Changed between versions: what_changed. Code text: search_code. - fqn forms:…
project_profileAnswer "what is this contrib project, how big is it, which core versions does it support, what moves with it" for one drupal.org project. Pending change records: project_upgrade_report. Core symbols it calls: list_symbol_users. - project: title, type, status, security, installs.…
project_upgrade_reportAnswer "is this contrib project ready for a target core version, and what work is left". For one record's detail, use get_change_record. For a symbol's users, use list_symbol_users. - A record applies when it targets the target version or earlier, and a development branch of the…
query_datasetRun read-only DuckDB SELECTs over the dataset behind the other tools, for a question none of them asks. Call describe_dataset first; it lists the 36 views, their columns, joins and recipes. Prefer a typed tool when one fits. - statements=[…]: up to 5 statements in one call, one…
reroll_patchRe-roll one composer patch that check_patches reported conflicts or fuzzy: a new diff that applies to the installed release. Call check_patches first for the whole list. Call this once per patch that came back conflicts or fuzzy. - Input: project, version, patch, title, base. pa…
scan_composerWhich of a site's drupal/* packages need a new release for a target core, and which have none? Send composer.lock and composer.json once; do not query one package at a time. The answer is the release scan for every package, plus extra.patches as check_patches items. Constraints…
search_codeSearch the source of every indexed contrib project, plus core, for a code pattern: which files, or with by_repo which projects. Who-uses-a-core-symbol counts: list_symbol_users or lookup_core_symbol. - query is a regex. Set literal for exact text with ( [ ] . $ : or a space, and…
subsystem_couplingAnswer "what else tends to fail when a merge request touches this core subsystem" from CI history over about 9,000 core merge requests. With issue_nid: "which subsystems does this issue touch, and what co-fails with them". No arguments: the list of subsystems, the same one core_…
what_changedAnswer "what changed in the core API between two core versions": symbols added, deprecated and removed, as ranked groups with counts. One symbol: lookup_core_symbol. Human write-ups: list_change_records. Every row of one bucket: flat=true with bucket, paged. Every row of the who…
wordpal_themeAnswer "does this WordPress block theme convert to Drupal with WordPal". The WordPal gallery converts every block theme on wordpress.org each night. With slug: one theme and its routes. Without slug: counts by status and the most installed themes. - version: the theme version wo…
