apify-mcp-server: Skill for Claude Code

.claude/skills/bug-triage/SKILL.md

bug-triage is a skill for Claude Code from apify/apify-mcp-server. It costs 56 tokens per session (1,685 once invoked), scanned C, original, MIT.

A helper for reviewing open bug reports on the Apify MCP server, a software project that lets AI assistants use Apify services.

In plain words
What is it for?
Use it to review selected issues, all open bug-labelled issues, or issues matching a label. It drafts developer-to-developer replies and can post, close, or edit issues only after approval.
Why use it?
It gathers bug reports, investigates likely causes, and prepares responses, reducing the manual work of sorting and answering issues.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is apify/apify-mcp-server's own configuration. It tells Claude Code how to work on apify-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything apify-mcp-server configures →

About the project

Apify MCP Server connects AI agents to Apify's collection of web scrapers, crawlers, and automation tools through the Model Context Protocol, allowing them to extract data from websites, search engines, social media, maps, and online stores. It is for users who want agents to collect web data through compatible clients such as Claude Code, Claude.ai, Cursor, or VS Code. The catalogue entries configure or extend agent use of this MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

bug-triage scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

4. **npx cache corruption**: Stale cache prevents stdio server from starting. Fix: `rm -rf ~/.npm/_npx` (macOS/Linux) or `rmdir /s /q %LOCALAPPDATA%\npm-cache\_npx` (Windows).

Bug Triage

Triage open bug issues on apify/apify-mcp-server. Analyze, draft responses, get approval, post.

Permissions

  • Read-only by default: listing issues (gh issue list), viewing details and comments (gh issue view) — do these automatically, no need to ask.
  • Write requires approval: commenting (gh issue comment), closing (gh issue close), editing (gh issue edit) — always present the draft and wait for explicit user approval before executing.

Step 0: Parse arguments

$ARGUMENTS controls scope:

Input Behavior
623 641 639 Triage specific issue numbers
--label bug Triage all open issues with label (default: bug)
--all Triage all open bug-labeled issues
(empty) Same as --all

Step 1: Fetch issues

Use the arguments parsed in Step 0 to determine what to fetch.

If specific issue numbers were provided, skip the list queries and fetch each issue directly:

gh issue view <number> --repo apify/apify-mcp-server --comments

Otherwise (label mode, --all, or empty), fetch open bug reports. Use the label from Step 0 (default: bug). Bug reports come in two forms — find both:

  1. By label: issues with the parsed label
  2. By title prefix: issues with [Bug] in the title (the bug report template adds this, but the label isn't always applied)
# By label (use the label from Step 0, default: bug)
gh issue list --repo apify/apify-mcp-server --label <label> --state open --json number,title,labels,createdAt,body --limit 30

# By title prefix (catches unlabeled bug reports)
gh issue list --repo apify/apify-mcp-server --state open --search "[Bug] in:title" --json number,title,labels,createdAt,body --limit 30

Merge both lists and deduplicate by issue number.

For each issue, fetch full details including all comments (comments often contain the real context):

gh issue view <number> --repo apify/apify-mcp-server --comments

Always read comments before drafting a response. Previous team members may have already replied, asked for details, or provided workarounds. Don't duplicate existing responses.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
