- Asked for competitive intelligence
- Competitor tracking
- Market positioning research
- Competitive content monitoring
Example prompts
- “/competitor-monitor”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cbab581. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Competitor Monitor loads about 701 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 281 words of instructions outside code blocks.
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
- Monitor competitor websites, content changes, social activity, and market positioning through SandBase. Use when asked for competitive intelligence, competitor tracking, market positioning research, or competitive content monitoring.
Competitor Monitor
Cross-channel competitive intelligence through SandBase. Track competitor website content, social media activity, news coverage, and search visibility. Read the API map before selecting a capability.
Call SandBase capabilities
Use the capability identifiers below as discovery hints, not MCP tool names. Find the matching endpoint with sandbase_discover(q: "<provider and capability>"); use its returned name in sandbase_inspect(name: "<returned name>"). Read inputSchema, pricing, and execute_as, then call sandbase_run using execute_as.arguments.name and schema-defined arguments. If a run_id is returned, poll sandbase_run_get(run_id: "<returned run_id>") within the task budget until completed or failed; report pending or failed runs without resubmitting them automatically.
Operating principles
- Focus on observable, public behavior — don't speculate on internal strategy.
- Compare like-for-like: same time period, same metrics across competitors.
- Track multiple dimensions: content, social, search, news.
- Note what you can't observe (private channels, paid activity) as gaps.
Workflow
1. Website monitoring
Use firecrawl_scrape or context_dev_scrape_markdown to extract competitor page content.
Use firecrawl_map to discover competitor site structure.
Use context_dev_capture_screenshot for visual monitoring.
2. Search visibility
Use exa_search with include_domains to find competitor content.
Use dataforseo_v3_serp_google_organic_live_advanced to check their rankings.
3. Social monitoring
Use twitter_web_search_timeline for competitor brand mentions.
Use linkedin_web_v2_company_posts for competitor LinkedIn activity.
Use youtube_web_v2_channel_videos for competitor YouTube content.
4. News tracking
Use tavily_search with competitor name and "news" topic.
Use google_news_bulk_articles for news coverage.
Output
Return: competitor activity summary, content changes detected, social media presence comparison, search visibility snapshot, news coverage, and strategic observations.
Example tasks
- "Monitor [competitor]'s website — what pages have they added or changed?"
- "Compare [our brand] vs [competitor] social media activity this month."
- "What's [competitor] ranking for that we're not?"
- "Track [competitor]'s recent news coverage and announcements."
- "Analyze [competitor]'s LinkedIn content strategy — what topics, cadence, engagement?"
