Claude-skill-registry context7-cli

Use the local Context7 CLI in this repo to search libraries and fetch Context7 context for skills or documentation tasks. Trigger when you need to run `c7 search`/`c7 context`, resolve library IDs, or retrieve text/json outputs from Context7 via the CLI.

Context7 CLI

Overview

Use the local

agent-skills

CLI (subcommand

c7

) to query Context7 for library discovery and context snippets. Prefer this tool when a task needs authoritative library context and you want a deterministic CLI output that can be piped into downstream steps.

Quick Start

Ensure
```
CONTEXT7_API_KEY
```
is set or pass
```
--api-key
```
.
If
```
agent-skills
```
is already installed, use it directly:

command -v agent-skills
agent-skills c7 search --library-name react --query "useEffect cleanup"

Otherwise, run the CLI from the repo:

go run ./cmd/agent-skills c7 search --library-name react --query "useEffect cleanup"

For repeated calls, build once:

go build -o bin/agent-skills ./cmd/agent-skills
./bin/agent-skills c7 context --library-id /facebook/react --query "useEffect cleanup"

Or install remotely (requires Go) only if the binary is missing:

if ! command -v agent-skills >/dev/null 2>&1; then
  go install github.com/strantalis/agent-skills/cmd/agent-skills@latest
fi
agent-skills c7 search --library-name react --query "useEffect cleanup"

Tasks

Search for libraries

Use this to discover candidate library IDs.

go run ./cmd/agent-skills c7 search --library-name react --query "useEffect cleanup"

Default output is JSON. Use
```
--format jsonl
```
for JSON lines or
```
--format text
```
for tab-separated lines.
Use
```
--limit
```
to reduce results when you only need the top few.

Fetch context

Prefer explicit

--library-id

for determinism.

go run ./cmd/agent-skills c7 context --library-id /facebook/react --query "useEffect cleanup"

If you only have a name, you may use

--library-name

. If multiple libraries match, use

--select=interactive

--select=first

, or provide

--library-id

for determinism.

go run ./cmd/agent-skills c7 context --library-name react --query "useEffect cleanup"

Output formats

Use
```
--format json
```
when another tool or step needs structured output.
Use
```
--format jsonl
```
for streaming or piping one JSON object per line.
Use
```
--format text
```
for direct reading or quick copy/paste.

Flags (global to

c7

)

```
--api-key
```
(or
```
CONTEXT7_API_KEY
```
): Context7 API key.
```
--base-url
```
: Override the Context7 base URL.
```
--timeout
```
: HTTP timeout (default 30s).
```
--retries
```
: Retry count for 202/429/5xx responses.
```
--cache-dir
```
: Enable disk cache when set.
```
--cache-ttl
```
: Cache TTL (default 24h, only used when cache-dir is set).

Troubleshooting

401/403: Missing or invalid API key. Set
```
CONTEXT7_API_KEY
```
or pass
```
--api-key
```
.
429: Rate limited. The client retries automatically; reduce request rate if persistent.
202: Context is still processing; retries will handle this automatically.
