Description
Query the COCA (Corpus of Contemporary American English) linguistics API for word frequency, collocations, concordances, and historical usage trends. Use for...
README (SKILL.md)
Dreamer Corpus
Access the COCA corpus API at https://api.dr.eamer.dev.
COCA contains 1+ billion words of contemporary American English from spoken, fiction, magazine, newspaper, and academic sources.
Authentication
export DREAMER_API_KEY=your_key_here
Endpoints
Word Search / Concordance
GET https://api.dr.eamer.dev/v1/corpus/search?word=serendipity&limit=20
Returns KWIC (keyword-in-context) examples showing the word in actual usage.
Collocations
GET https://api.dr.eamer.dev/v1/corpus/collocations?word=run&pos=verb&limit=20
Returns words that statistically co-occur with the target word (MI score, frequency).
Frequency
GET https://api.dr.eamer.dev/v1/corpus/frequency?word=algorithm&genre=academic
Returns frequency per million words, with optional genre filter: spoken, fiction, magazine, newspaper, academic.
When to Use
- Checking how formal or common a word is in real American English
- Finding natural collocations for writing assistance
- Linguistic research on word usage patterns
- Historical frequency trends across decades
Don't Use When
- You need non-English corpora
- You need corpora other than contemporary American English (COCA is 1990-present)
Usage Guidance
Do not install or use this skill until the developer clears up the inconsistencies. Ask for: (1) the canonical API provider and official docs proving access to COCA (an authoritative domain or project page), (2) why the registry lists no required env vars while SKILL.md requires DREAMER_API_KEY, and (3) a source/homepage or repo so you can inspect who runs api.dr.eamer.dev. Treat any queries you send to the service as potentially logged by an unknown third party; avoid sending sensitive text. If you cannot verify the API's legitimacy, prefer a skill backed by a known provider or one that documents its data provenance and credentials in the manifest.
Capability Analysis
Type: OpenClaw Skill
Name: geepers-corpus
Version: 1.0.0
The skill bundle defines an API interaction with 'api.dr.eamer.dev' for linguistic data, requiring an API key via an environment variable. All instructions in SKILL.md are descriptive of the API's usage and endpoints, without any evidence of prompt injection attempts, malicious command execution, data exfiltration, or other harmful behaviors. The external API calls are the core stated purpose of the skill.
Capability Assessment
Purpose & Capability
The skill description says it queries COCA, but the runtime instructions name the service 'Dreamer Corpus' and point to https://api.dr.eamer.dev (not an official COCA/english‑corpora host). The package metadata (name 'Geepers Corpus') doesn't match the SKILL.md branding. The lack of source/homepage makes it impossible to verify that this endpoint legitimately provides COCA data.
Instruction Scope
SKILL.md instructs the agent to call external endpoints and to set DREAMER_API_KEY. It does not request local file access, which is appropriate, but the instructions direct all queries to an unverified external host and ask the agent to use an API key (not declared in registry). There is nothing in the document indicating why a third‑party host is necessary or whether user queries or results are logged/shared beyond the API.
Install Mechanism
Instruction‑only skill with no install spec and no code files — nothing will be written to disk by an installer. This is a low install risk.
Credentials
The registry metadata lists no required environment variables, but SKILL.md instructs users to export DREAMER_API_KEY for authentication. That mismatch is a red flag: the skill will expect a secret not declared in its manifest, and the origin/scope of that credential is unclear.
Persistence & Privilege
always is false and there are no indications the skill requests persistent system privileges or modifies other skills/config. Autonomous invocation is allowed by platform default; that combined with the other concerns increases risk but is not by itself unusual.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install geepers-corpus - After installation, invoke the skill by name or use
/geepers-corpus - Provide required inputs per the skill's parameter spec and get structured output
