What it does

Dictionary Lookup is an agent skill from mohitagw15856/pm-claude-skills. Look up word definitions, pronunciation, etymology and synonyms with zero API keys — the Free Dictionary API via curl, with honest handling of words it doesn't know. Use when asked define a word, how do you pronounce this, what's the origin of a word, or synonyms for something. Produces the definition set organized by part of speech, IPA pronunciation with audio link, and the rerunnable command — with the model's own knowledge clearly separated from the fetched source.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Education, covering Language learning. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked define a word
  • How do you pronounce this
  • Whats the origin of a word
  • Synonyms for something

Example prompts

  • “t know. Use when asked define a word, how do you pronounce this, what”
  • “/dictionary-lookup”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. The call: curl -s "https://api.dictionaryapi.dev/api/v2/entries/en/serendipity" → JSON array: phonetic/phonetics[] (IPA + .audio mp3…
  2. Lead with the asked-for thing: a pronunciation question gets IPA in line one, not after four noun senses; an is-it-a-word check gets…
  3. The miss is information: a 404 means this API lacks the word — common for new coinages, technical jargon, and inflected forms. Report…
  4. Sense selection over sense-dumping: when context implies a sense, lead with it and compress the others to one line each; "mean" has a…
  5. Supplement with labels: the API's synonym lists are often thin — model-added synonyms go under "additional (model-suggested)," keeping the…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.dictionaryapi.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Dictionary Lookup loads about 1.1k tokens when it runs. Until then it costs about 123 tokens; SKILL.md has 576 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~123
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Look up word definitions, pronunciation, etymology and synonyms with zero API keys — the Free Dictionary API via curl, with honest handling of words it doesn't know. Use when asked define a word, how do you pronounce this, what's the origin of a word, or synonyms for something. Produces the definition set organized by part of speech, IPA pronunciation with audio link, and the rerunnable command — with the model's own knowledge clearly separated from the fetched source.

Dictionary Lookup Skill

A dictionary lookup sounds like something a language model shouldn't need — until the question is "is this actually a word," "what's the IPA," or "give me a citable source," where fetched beats recalled. The Free Dictionary API answers over keyless HTTPS with definitions, phonetics, audio, and origins. This skill fetches, formats by part of speech, and keeps a clean line between what the source says and what the model adds — because a dictionary answer's whole value is knowing which is which.

What This Skill Produces

  • The entry — definitions grouped by part of speech, with example sentences where the source has them
  • Pronunciation — IPA text and the audio-file link when available
  • Synonyms/antonyms — from the source, supplemented (and labeled) by the model when thin
  • The command — exact curl, rerunnable; and an honest miss-report when the API lacks the word

Required Inputs

Ask for these if not provided:

  • The word — and the sense if context suggests one ("mean" the verb, the adjective, or the statistic?)
  • What they actually need — a quick meaning, pronunciation, etymology, or a citable check that a word exists — the output leads with it
  • Language note — this API is English-only; other languages get an honest redirect (Wiktionary manually) rather than a fake answer

Framework: Fetch, Format, and the Honesty Line

  1. The call: curl -s "https://api.dictionaryapi.dev/api/v2/entries/en/serendipity" → JSON array: phonetic/phonetics[] (IPA + .audio mp3 links), meanings[] grouped by partOfSpeech, each with definitions[] (with example sometimes), synonyms, antonyms, plus origin on some entries.
  2. Lead with the asked-for thing: a pronunciation question gets IPA in line one, not after four noun senses; an is-it-a-word check gets yes/no plus the entry as proof.
  3. The miss is information: a 404 means this API lacks the word — common for new coinages, technical jargon, and inflected forms. Report exactly that, try the lemma (running → run), and if the model still knows the word, define it clearly labeled as model knowledge, not the fetched source. Never dress recall as a citation.
  4. Sense selection over sense-dumping: when context implies a sense, lead with it and compress the others to one line each; "mean" has a dozen senses and the user wanted one.
  5. Supplement with labels: the API's synonym lists are often thin — model-added synonyms go under "additional (model-suggested)," keeping the source's authority intact for the part that claims it.

Output Format

[part of speech] — [the leading sense, with example] [Other senses, compressed · other parts of speech]

Origin: [when present in source or asked — labeled if model-supplied] Synonyms: [source list] [· additional (model-suggested): …]

Source: Free Dictionary API · rerun: [exact curl] [On a 404: "not in this dictionary — tried '[lemma]'; the definition below is model knowledge, not a fetched source"]

Quality Checks

  • The asked-for element (meaning/IPA/origin/existence) leads the answer
  • Definitions are grouped by part of speech, contextual sense first
  • Source content and model additions are visibly separated
  • 404s report the miss and try the lemma before falling back
  • The rerunnable curl appears

Anti-Patterns

  • Do not present model recall as the fetched entry — the label line is the skill's integrity
  • Do not dump every sense undifferentiated when context picked one
  • Do not fake non-English lookups on an English-only API — redirect honestly
  • Do not treat a 404 as "not a word" — it's "not in this dictionary," a much smaller claim
  • Do not skip pronunciation when the question was spoken-word-shaped (names, presentations, ESL contexts)

Example Trigger Phrases

  • "Define a word."
  • "How do you pronounce this?"
  • "What's the origin of a word?"
