Check a citation against the registry of record instead of recalling it. Use this to verify that a DOI or a reference actually exists, to get the real title, authors, journal, year, licence, funders and citation counts behind a DOI, to find the DOI for a half-remembered paper title, to audit a bibliography or reference list before it ships, to resolve an ORCID iD to a researcher's employments, educations and recent publications, and to tell two same-named authors apart. Reach for it whenever an invented citation is the way the task fails — a fabricated reference reads exactly like a real one, with a plausible journal, plausible authors and a DOI of the right shape, and only the registry separates them. Crossref holds what publishers deposited and ORCID holds what researchers claim; neither is recallable from training data. Browsing, searching and dry runs cost nothing and need no wallet; a real call costs $0.003 to $0.004 in USDC on Base, with no signup, no API key and no gas.
Manage Symfony configuration with .env files, parameters, secrets vault, and environment-specific settings
The UTC offset, abbreviation and DST state a zone was on at any moment from 1970, with the surrounding transitions, and resolution of ambiguous or nonexistent local times. Called as GET /v1/tz/offset-at, it takes timezone, instant, localTime and returns timezone, utcOffset, isDst, resolution. An agent scheduling or reconciling timestamps must know that 01:30 on a fall-back night happens twice and 02:30 on a spring-forward night never happens at all; fixed offset arithmetic silently books the wrong hour. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.004, paid in USDC on Base over x402.
Execute an implementation plan through to a verified, committed code change. Use after `plan-implementation` produces the ordered `Stages` plan.
This skill should be used when the user asks to implement Phaser 4 game code, create or edit scenes, add players, enemies, scoring, collectibles, movement, shooting, animations, input, physics behavior, game objects, or complete gameplay features in TypeScript.
Scandit Barcode Capture (`BarcodeCapture`) in native iOS (Swift) projects — the low-level, full-control single-barcode scanning mode (BarcodeCapture + DataCaptureView + overlay), without the pre-built SparkScan UI. Use for integration, scan settings, result handling, overlay customization, SDK version migration (v6→v7→v8), replacing a third-party barcode scanner, or troubleshooting.
UTC sunrise, sunset, solar noon and day length for a date and coordinate, including polar day/night. Called as GET /v1/time/sunrise-sunset, it takes date, lat, lon and returns sunrise, sunset, dayLengthSeconds. An energy, imaging or scheduling agent needs daylight bounds at a location before it can plan solar yield, a shoot, or a delivery window. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
Validate an ISO 17442 Legal Entity Identifier checksum and extract its issuing LOU prefix. Called as GET /v1/valid/lei, it takes lei and returns valid, lou. Observed on-chain demand: a compliance agent resolving a counterparty needs to know an LEI is well-formed before spending a lookup against a registry. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
Recent drug enforcement actions and recalls for a product or firm, with classification and reason. Called as GET /v1/fda/drug-recall, it takes query, limit and returns count, recalls. Distinct from the neighbouring services in this domain by: drug, recent, actions, recalls, classification. A supply-chain or pharmacy agent must check whether a lot has been recalled before acting on it, and recalls are recent events no model has seen. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.004, paid in USDC on Base over x402.
Generate CSPRNG bytes from the Web Crypto API, returned as hex, base64 or a UUID. Never Math.random. Called as GET /v1/crypto/random-bytes, it takes bytes, encoding and returns value, encoding. Observed on-chain demand: agents need unguessable nonces, tokens and idempotency keys, and a language runtime without a CSPRNG or a model asked to "pick a random number" both produce predictable output. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
This skill should be used when the user asks to "write a game design document", "create a GDD", "design my game", "document game mechanics", "plan game progression", "define core loop", "art direction", "audio design plan", "monetization strategy", "game concept document", "plan my game before coding", or wants to produce a structured design document for a Phaser 4 game before writing any code.
Write functional tests for Symfony controllers and HTTP endpoints using WebTestCase, getContainer, loginUser, and DAMA rollback
