How does this batch differ from the science/chemistry batch?

That guide covered ideal gas, pH, and SHAKE hashes. This set focuses on descriptive statistics, text frequency tables, Fletcher/CRC checksums, HTTP cookie parsing, and book or banking identifier format checks.

Are all 100 pages linked here?

No—each section points to representative tools. Browse Math, Writing, Security, Encoding, Protocol, Schedule, and Identity tabs for the full list.

Can agents prefill these tools?

Single text fields often accept q or qb. Multi-field date, number, and key+message tools open without URL prefill.

Statistics, text analysis, and header tools — what to open when

Another hundred tools landed across seven themes—descriptive statistics and geometry-lite, text frequency and line cleanup, extended digests, Base62 and z-base-32 encoding, HTTP header parsers, calendar quarters, and publishing or supply-chain identifier checks. Start here when you know the job, not the route name.

The latest Toolcore batch adds another hundred browser-local pages in statistics and geometry-lite math, text frequency and line analysis, extended digests and checksums, Base62 and z-base-32 encoding, HTTP header parsers, calendar quarter math, and book or banking identifier checks. Use this map when you know the job—not when you want to scroll the full catalog.

Statistics, combinatorics, and geometry-lite

Sample mean, median, and sample standard deviation — descriptive stats from comma-separated lists.
Z-score, normal CDF, and margin of error — standardize values and survey proportion MOE.
Binomial probability, permutations nPr, and combinations nCr — discrete probability and counting homework.
Heron triangle area, chord length, and circle segment area — geometry-lite when you know side lengths or radius and angle.

Text frequency, lines, and cleanup

Analyze pasted prose or logs locally—counts, duplicates, and lightweight transforms without uploading files.

Character frequency table and word frequency rank — see which symbols and words repeat.
Bigram and trigram frequency — phrase-pair counts for stylometry drills.
CRLF vs LF counts, trailing-space lines, and trim each line — line-ending and whitespace audits before commit.
Bracket balance, sort words, and join words with commas — quick structural checks and list formatting.

Hashes, HMAC, and checksums

SHA3-224 and SHA3-384 — SHA-3 family digests for integrity tags.
HMAC-SHA256 and HMAC-SHA512 — webhook-style message authentication codes.
Fletcher-32, CRC-64 ECMA-182, and Jenkins one-at-a-time — non-crypto fingerprints and packet checksums.

Base62, Base91, and hex variants

Base62 encode / decode — alphanumeric without padding.
z-base-32 and uppercase hex — human-friendly token encodings.
Punycode domain encode / decode — ACE label hints for international domains.

HTTP request and response headers

Paste header text you already captured—these tools split tokens locally; they do not fetch URLs.

Accept, Accept-Encoding, and Authorization — content negotiation and auth scheme breakdown.
Cookie and Set-Cookie — session attribute lists from curl -v traces.
Retry-After, rate-limit headers, and CSP-Report-Only — throttling and dry-run policy directives.

Calendar math and identifier format checks

Calendar quarter, fiscal year quarter, and weeks between dates — planning spans without a spreadsheet.
ISBN-10 validator, ISBN-13 check digit, and ISSN check digit — publishing metadata checksums.
SWIFT/BIC format and CAGE code validator — structure checks only, no live directory lookup.
