Toolcore added nine pages aimed at the stuff developers paste every day: identifiers, config snippets, shell commands, markup, and small calculations. None of them replace your editor—they save a context switch when you only need one clear answer.
Validate before you import
Bad fixtures waste a CI run. When someone drops a list of IDs or a config blob in chat, open a validator first:
- UUID validator — one UUID per line; checks hyphen shape, version nibble, and RFC variant.
- XML validator — well-formedness and parse errors with a readable message (not a full schema engine).
Pair the UUID page with the existing UUID generator when you need fresh fixtures after validation passes.
Config files and shell one-liners
YAML from Kubernetes or Helm often arrives minified. A curl example from docs rarely includes only the URL you care about.
- YAML formatter — indent and line-break messy YAML before review. For JSON pivots, the JSON ↔ YAML hub route still exists.
- cURL parser — paste a full
curl …line; read method, URL, headers, and body without executing the request. Follow with HTTP fetch only when you intentionally want a live response.
Crypto, preview, and synthetic rows
- PBKDF2 derive — password, salt, iterations, and hash algorithm to hex/base64 test vectors. Use synthetic passwords on shared screens.
- HTML preview — render pasted markup in a sandboxed iframe before it hits an email template or CMS field.
- Test data generator — quick rows of names, emails, or numbers when you need filler for a spreadsheet or API mock—not production PII.
GPA and focus (non-code, still useful)
Two pages sit outside strict dev work but show up in the same “I need a number now” moment:
- GPA calculator — weighted grades with credit hours; handy for students and bootcamp cohorts sharing progress.
- Pomodoro timer — 25/5-style focus blocks in the same tab as your other tools; no account required.
A sensible try order
Search the navbar for the noun in your paste (uuid, yaml, curl). Each page ships with a loadable example— click it once to see output shape, then replace with your paste. For automation, the same routes appear in agent manifests with prefill notes where URL parameters are safe.
