Parses up to 20 Kubernetes YAML manifests and checks that they agree with each other, for an agent that generated or edited manifests before kubectl apply: Service selectors against pod template labels (with the nearest near-miss), named targetPorts against containerPort names, Service port naming, Deployment selector against its template labels, Ingress backends against Services, and ConfigMap/Se

Takes an AWS IAM policy JSON and the exact list of actions a task needs (up to 300), and returns the policy with each Allow statement's Action narrowed to just those actions, plus what the original over-grants: wildcards, unused actions, Allow+NotAction, required actions no statement grants, and required actions an unconditional Deny blocks. For an agent that is about to attach or propose a policy

Turns up to 50 literal strings into a safely quoted argument for bash/sh (POSIX single-quote method), PowerShell (single-quoted literal) and cmd.exe, for agents that build a command line from untrusted or free-form text, and parses each result back with a model of that shell's rules to prove it yields the original string. It returns `unsupported` for strings cmd.exe cannot carry safely (line break

Computes exact CIDR relations for agents planning networks, firewall rules or allow-lists: for up to 200 IPv4/IPv6 blocks it reports which pairs are equal, nested, partially overlapping or merely adjacent, the minimal merged CIDR list, a subtraction (blocks minus exclusions), address membership with the most specific match, or each block's first/last address, count and host-bits-set errors. It doe

Explains from supplied response headers (and optionally the request's headers, a CORS request, and a redirect chain) whether a shared and a private HTTP cache may store the response (RFC 9111 section 3), its freshness lifetime and basis (s-maxage, max-age, Expires minus Date, or the 10% Last-Modified heuristic), Vary, invalid max-age or Expires, the CORS check and preflight outcome per the Fetch S

Canonicalizes up to 50 absolute http(s) URLs for an agent about to fetch, dedupe or click them: WHATWG-parsed lowercase host, default port and fragment and userinfo removed, dot segments and unreserved percent-escapes normalized, tracking parameters (utm_*, gclid, fbclid and the Mozilla strip list plus yours) removed, and flags userinfo@host tricks, backslash and multiple-@ authorities, obfuscated

Reads a supplied robots.txt the RFC 9309 way for an agent deciding whether to fetch up to 25 paths as one product-token user agent: group selection (merged groups, "*" fallback), longest-match with the Allow-wins-tie rule, "*" and "$" patterns, percent-encoding normalization, fetch-status handling (4xx = no rules, 5xx = disallow all), the rule and line that decided each path. It also lints a suppl

Walks a supplied HTTP redirect chain (up to 25 hops of status + Location) for an agent or HTTP client author and reports, per hop, which of the request's header names (Authorization, Cookie, Proxy-Authorization, API-key-like, Referer) are stripped or still forwarded, the method after the hop (301/302 POST to GET, 303, 307/308), whether the hop crosses origin, scheme, or registrable domain, an http

Checks a manifest of up to 2000 archive entries (path, type, link target, sizes) before extraction, for an agent that unpacks zip, tar or OOXML files: ../ traversal (also through backslashes), absolute, drive-letter and UNC paths, entries that write through a symlink, symlink and hardlink targets that leave the root, duplicate destinations, case-only and NFC/NFD collisions, Windows reserved names,

Checks up to 500 relative file paths for names that break or collide on Windows, macOS or Linux: Windows reserved device names (CON.txt, NUL.tar.gz, COM¹), reserved characters, trailing dots and spaces, component and total length limits, and distinct paths that become one file through case folding or NFC/NFD normalization. For an agent that writes files from an archive, a generated tree or a repo

Compares a claimed file type (MIME type and/or file name) with the first bytes of the file, for an agent that is about to open, parse or forward a download. Detects PNG, JPEG, GIF, WebP, ZIP and OOXML (docx/xlsx/pptx), GZIP, PDF, MP4 (ftyp), ELF, PE, RAR, BMP, ICO and HTML, flags an HTML login or error page saved as a PDF/image/archive, and reports truncation from end-of-file markers when the last

Lists which privacy-relevant EXIF tags exist in a JPEG, TIFF, PNG (eXIf) or WebP (EXIF) image, for an agent that is about to publish, upload or forward a photo. Reports tag ids and names for GPS, body and lens serial numbers, camera owner, artist, unique image id, device, software, timestamps and thumbnails; values are never returned. Input is the image as base64 (up to 96 KiB, enough for the meta

Checks up to 200 SVG shapes you describe (rect, circle, ellipse, line, polygon, polyline, text, or a path's bounding box) against the viewBox and viewport the way an SVG renderer would: finds shapes clipped or entirely outside the drawn region, shapes that render nothing (zero or negative size, unstroked line), partial overlaps between shapes, and a zero, negative or malformed viewBox, for agents

Checks the five PDF page boxes you supply (MediaBox, CropBox, BleedBox, TrimBox, ArtBox, in points) for a print job: applies the ISO 32000-1 defaults and media-box clipping, measures bleed on each side of the trim box, and tests the content box against a safe margin inside the trim, for agents that prepare or accept print-ready PDFs. It does not read a PDF file, check fonts, colour, image resoluti

Checks up to 1000 coordinate pairs (or one bounding box) against the EPSG coordinate system you name, for agents handling GIS or map data: it flags longitude/latitude swaps, degrees supplied where metres are expected (or the reverse), values outside the CRS's area of use, and inverted bounds, with the point index and values. It does not reproject, geocode, validate geometry topology or datum, or j

Converts up to 100 values between units for an agent that needs the exact factor and a refusal when the units do not match: SI and NIST SP 811 length, mass, time, volume, pressure, energy, power, temperature, with compound expressions like kg*m/s^2. Rejects incompatible dimensions, converts absolute temperatures affinely through kelvin and temperature differences linearly, and converts mass to vol

Scales up to 60 ingredient quantities by a servings ratio or a factor for an agent resizing a recipe or batch formula, applying per-ingredient rules the caller declares: linear (the labelled default), power exponent, fixed amounts, min/max clamps and rounding steps, with an optional display unit via unit-convert. Reports what rounding did (relative drift, rounds-to-zero). It does NOT know which in

Scans an ingredient list for terms tied to the 14 allergens of EU Regulation 1169/2011 Annex II and the 9 US major food allergens (FALCPA plus sesame under the FASTER Act), for an agent or buyer checking a label or recipe. Returns each matched span with its character offsets, the allergen, the regime that lists it, and whether it sits in a 'may contain' clause. Pass the allergens a label declares

Checks up to 50 foreground/background hex pairs against a WCAG 2.2 contrast threshold (4.5 AA text, 3 large text and UI, 7 AAA, or your own) on the unrounded ratio, so 4.499 fails and exactly 4.5 passes, and for a failing pair returns the closest colour by OKLCH lightness (chroma and hue held, gamut-clipped, 8-bit) that meets it. Optionally simulates protanomaly, deuteranomaly and tritanomaly (Mac

Parses a chemical formula (parentheses, brackets, hydrate dots such as CuSO4·5H2O, an ignored charge) for a chemist or an agent that must check a molar mass, and returns the Hill-notation formula, the formula weight in g/mol from the CIAAW abridged standard atomic weights summed exactly in decimal arithmetic, and mass fractions. Pass claimedWeight and tolerance to check a stated molar mass. Elemen

Given any three of aperture (f-number), shutter time in seconds, ISO and scene EV at ISO 100, solves the fourth from EV = log2(N^2/t) and EV_S = EV_100 + log2(S/100), names the nearest one-third-stop f-number, and lists the equivalent shutter time at each f-number from f/1 to f/32. Given all four, checks that they agree within a tolerance in stops. Built for camera, lighting and image-generation a

Computes sun elevation, azimuth, declination, equation of time, sunrise, solar noon and sunset (UTC) for a latitude/longitude and up to 100 caller-supplied instants using the NOAA Global Monitoring Laboratory solar calculator equations (Meeus). Polar day and polar night return sunrise and sunset as null with a reason, not an error. Reads no clock: every instant comes from the caller. Does not mode

Given an image's pixel size and a print size (inches, millimetres or centimetres) plus optional bleed, margin and target ppi, returns the effective ppi over trim plus bleed, whether it meets the target, the pixel count a target ppi needs, the largest print size a target ppi allows, the safe area, and the exact uncompressed bitmap size. Built for print-on-demand, layout and image-prep agents; the t

Decodes up to 20 METAR or SPECI aviation weather reports (US and ICAO forms: wind with gusts and variable direction, visibility in statute miles or metres, CAVOK, RVR, present weather, cloud layers, temperature/dew point, altimeter, trend, RMK remarks) into structured fields and computes the FAA flight category (LIFR/IFR/MVFR/VFR). Every token it cannot decode is returned with its character offset

Checks whether a move (or a sequence of moves) is legal from a FEN position under the FIDE Laws of Chess, for agents that play, annotate or verify chess games. Accepts UCI or SAN, returns the normalized move, the new FEN, check / checkmate / stalemate / insufficient-material flags and, if asked, every legal move; an illegal move names the reason (castling_through_check, ep_exposes_king, moves_into

Rolls dice notation (for example 4d6kh3+2) from a caller seed with a documented SHA-256 counter-mode stream and returns every die, the kept/dropped marks and a full draw transcript, for agents and referees that need a roll anyone can re-derive. Optionally checks a claimed total or claimed faces against the re-derived roll. Does NOT provide unpredictable randomness: the seed is public input, so any

Computes the haversine (IUGG mean-radius sphere) and Vincenty inverse (WGS-84 ellipsoid) distance in metres plus initial and final bearings for up to 100 coordinate pairs, and optionally checks a claimed distance within a tolerance. Vincenty is millimetre-accurate except for nearly antipodal pairs, where it does not converge: those pairs return vincentyMeters null, status unknown and the haversine

Replays a tennis point sequence (ITF Rules of Tennis: games, deuce, tie-breaks, match tie-break, who serves), computes a golf Score Differential and Handicap Index (World Handicap System), or tallies a cricket innings ball by ball (overs.balls, wides and no-balls, maidens, wickets), for agents that must verify a reported score. Optionally checks a claimed score against the replay and names the fir

Names a chord from its notes, spells a chord symbol into notes, tests whether a chord is diatonic to a key, or transposes a chord symbol, using pitch-class arithmetic over a fixed table of 21 chord qualities, for agents handling lead sheets and music metadata. Rule-based and labelled: when several readings are equally valid (C E G A is C6 or Am7/C) or no quality in the table matches, it returns un

Computes Ohm's law and power from any two of V, I, R, P; series and parallel resistance with optional tolerance bounds; a voltage divider (with optional load); an LED series resistor rounded up to a preferred E-series value; conductor voltage drop from a caller-supplied resistivity; decodes or encodes 3 to 6 band IEC 60062 resistor colour codes; and tests whether a value is an official E3 to E192

Computes the minimum and maximum of a linear dimensional stack (the gap) from signed contributions with symmetric, unequal-bilateral, unilateral or min/max limits, both by exact worst-case arithmetic and by root-sum-square, names the dominant contributor and tests the gap against a required minimum and/or maximum. For mechanical designers and agents checking clearances. It does not do 2D or 3D sta

Checks whether up to 50 box-shaped items (axis-aligned, 90-degree rotations, optional this-side-up lock, optional weights) fit into any of up to 20 candidate cartons, and recommends the smallest-volume carton for which a packing was found, with coordinates for every item. For shipping and fulfilment agents sizing a parcel. The packing is a greedy extreme-point HEURISTIC with a fixed step cap, not

Tags each contract-style clause you supply with the modal force it expresses (obligation, prohibition, permission, recommendation) and topic cues (definition, condition, termination, payment, confidentiality, liability, governing law, notice, assignment), with the matched cue and its offset. For an agent that must triage many clauses before a human or model reads them. Fixed cue phrases only (plus

Allocates a demand quantity across up to 200 inventory lots under a stated policy (FIFO by received date, FEFO by expiry, LIFO, or fewest lots), excluding held, expired, short-shelf-life and wrong-location lots, in whole case multiples if asked. For warehouse and order agents. Returns the pick plan, the shortfall and a reason for every excluded lot. A caller asOf date is required (the check never

Counts syllables per word and per line for English text, using your dictionary entries first and otherwise a rule-based estimator (vowel groups, silent e, -ed/-es, consonant+le). Optionally checks each line against a target pattern such as 5-7-5. Where the rules cannot decide (vowel pairs like ia/io/eo, acronyms, numerals, non-Latin scripts) the word is a range or abstains, and a line whose count

Evaluates a checklist of requirements the caller defines (each made of needs on evidence keys: present, equals, one of, min/max, maximum age) against evidence the caller supplies, and returns met / unmet / unknown per requirement with the exact need and value that decided it. For an agent that must prove a task's acceptance criteria were covered before it reports done. Does not judge whether the p

Checks whether the proof-of-delivery evidence supplied (signature, photo, timestamp, GPS fix, recipient name, scan ...) satisfies the carrier or contract requirement list the caller gives: every required item, plus optional 'at least k of these' groups, with value bounds (for example GPS accuracy at most 30 m) and maximum age. For an agent assembling a delivery dispute or a payment release. Return

Checks whether an intended action on a website (read, crawl, submit, log in, ...) satisfies the access rules the caller supplies (robots rule read, terms clause, login present, rate-limit budget, captcha seen) against facts the caller observed, and says which rule blocked it or which fact is missing. For an agent deciding whether to proceed or ask. It is a reading of the caller's rules, not legal

Checks whether a manual, service bulletin or procedure applies to a specific unit by comparing the scope the document declares (models, firmware or revision range, serial range, exclusions) with the unit's facts the caller supplies. Versions written as dotted digits (2.10.1) compare numerically per segment. For an agent about to follow a repair or configuration procedure. Applicable only when ever

Lets many agents agree which one works on a task: acquire a named resource for 1-3600 s, renew it while working, release it when done. Every new acquisition returns a strictly larger fencing token; pass it to the downstream store and reject writes carrying a smaller one, so a paused holder whose lease expired cannot clobber its successor. Re-acquiring as the current holder extends the lease with t

Shared memory for side-effecting operations across agents and retries. begin(key) answers proceed (you hold a short claim), wait (another owner is mid-flight), already_completed (returns the stored result pointer), or fingerprint_mismatch (same key, different operation). complete(key) records the result pointer; abandon(key) lets someone retry. The claim expires, so a crashed worker does not block

One rate limiter shared by every agent in your fleet. take(cost) atomically spends tokens if available and returns allowed plus remaining, or refuses with retryAfterMs until enough tokens refill. capacity and refillPerSecond are fixed when the bucket is first used; a call with different settings is refused so two fleets cannot silently disagree. Use a requestId so a retried take is not charged twi

Given the target document id, the supplied set of documents (id, effective date, which ids each one supersedes, withdrawn flag) and a reference date, reports whether the target is superseded or withdrawn as of that date, following supersession chains, and names the superseding document and its date. For an agent about to rely on a standard, price list, policy or datasheet revision. It can only see

Hands out strictly increasing integer blocks from a named sequence (1-1000 ids per call) so parallel agents never issue the same invoice, ticket or order number. Numbers are never reused. Not gapless: a block an agent reserves and never uses stays a gap, and if your call's payment fails after the block is written the same requestId returns that same block on retry. Legally gapless series must be a

A budget shared by a task tree, in integer minor units. reserve() atomically holds an amount if the remaining budget covers it (expired holds are freed automatically); commit() records what was actually spent, up to the hold; release() frees a hold. These are real reservations, not a snapshot: two workers cannot both reserve the last dollar. It records spending; it does not move money.

Caches a result under the SHA-256 of the canonical (JCS) request, so every agent in your fleet that makes the same request reuses one answer for up to an hour. get returns hit with the value and age, or a miss (status unknown). Scoped to your wallet or tenantId, never shared across customers, so nobody else can poison your cache.

Evaluates your own policy (JsonLogic rules, each allow or deny, deny-overrides or first-match, default deny) against a proposed tool call, payment or action, and returns allow or deny, the rule id that decided, and a receipt signed by the hub over the hashes of the policy, the request and the decision. The receipt is the product: another agent or an auditor can verify offline which rule allowed th

Runs your deterministic acceptance tests (equals, exists, absent, type, contains, length and number ranges, one-of, sha256, a JSON Schema subset) against a sub-agent's or vendor's JSON output at JSON Pointer paths, and returns per-test results plus a hub-signed receipt over the output hash, the tests hash and the results. Use it before paying for delegated work or releasing the next step. It certi

Lets every agent in your fleet record what it observed and read what the others saw, with freshness: endpoint brownouts and latency, rate-limit behaviour, IVR menu paths that worked, whether an ambiguous submission was later accepted or rejected, fixes for an error signature, stale feeds, page recipes, merchant workflow failures, document reputation. record() appends timestamped observations for a

Bundles up to 20 calls to any pure micro check (catalog entries that are neither stateful nor network-reading, e.g. checksum, patch-anchor, allocate, business-deadline) into one x402 settlement, so each check costs $0.001. Every call is validated before payment; one invalid call rejects the batch with its index. Results come back in order, each exactly as the single-call endpoint returns it.
