c7
Fetches up-to-date library documentation from Context7 and saves to /tmp/context7/. Use when needing current API docs, code examples, library references, SDK documentation, or checking latest library versions. Triggers: context7, c7, library docs, fetch docs, current documentation, api reference.
Best use case
c7 is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Fetches up-to-date library documentation from Context7 and saves to /tmp/context7/. Use when needing current API docs, code examples, library references, SDK documentation, or checking latest library versions. Triggers: context7, c7, library docs, fetch docs, current documentation, api reference.
Teams using c7 should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# c7 - Context7 Documentation Fetcher
Fetch-only skill. Does NOT read docs into context.
## Usage
### Fetch documentation
```bash
scripts/c7.sh <library-name> "<query>"
```
Example:
```bash
scripts/c7.sh nextjs "app router middleware"
```
### List cached docs
```bash
scripts/c7.sh --list
```
### Force re-fetch (bypass cache)
```bash
scripts/c7.sh --force <library-name> "<query>"
```
## Workflow
1. Run `scripts/c7.sh <library> "<query>"`
2. Handle output:
- `CACHED: <path> (Xh old)` → Use AskUserQuestion: "Documentation for X is already cached (Y hours old). Use cached version or fetch fresh?"
- If re-fetch → run with `--force`
- If use cached → inform user of location, done
- Success (path printed) → inform user: "Documentation saved to <path>"
- `NOT_FOUND:` → Use AskUserQuestion: "Library not found in Context7. How should I proceed?" with options like retry with different name, skip, etc.
- `RATE_LIMITED:` → inform user rate limit hit, stop
- `API_ERROR:` → inform user of error, stop
3. Done. Do NOT read the file into context.
## Exit Codes
| Code | Output | Action |
|------|--------|--------|
| 0 | filepath | Success - report location |
| 0 | CACHED: path | Ask user: use cache or re-fetch? |
| 1 | NOT_FOUND: | Ask user for alternatives |
| 2 | RATE_LIMITED: | Inform user, stop |
| 3 | API_ERROR: | Inform user, stop |
| 4 | FUZZY_MATCH: | Ask user: "Context7 matched X instead of Y. Use this or try different name?" |Related Skills
