Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.02320 |
| Opus 5.5 | $0.00018 | $0.00928 |
| Sonnet 5.5 | $0.00009 | $0.00464 |
| Haiku 4.5 | $0.00004 | $0.00232 |
Grade A, and why
firecrawl-deep-research scanned grade A with 0 findings 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 today.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Firecrawl Deep Research
Adapt the investigation to the question and the evidence available. This plugin uses Firecrawl's search MCP connection, not the full suite. Resolve deferred tools through the host's tool discovery when needed and follow the live schemas; use only operations exposed by this connection. Never invent tools or translate CLI flags into tool arguments.
Frame the investigation
Prefer a focused workflow when it can complete the request, such as enrich-lead for supplied people or lead CSVs, find-leads for new prospects, business-contact-research for published organizational contacts, or read-docs for official documentation. Use deep research for broader cross-source synthesis; multiple records or tool calls alone do not require it. Keep reusable evidence when switching workflows.
Invocation does not require an exhaustive investigation. Start with the smallest useful retrieval and expand only for gaps that could change the answer. Do not start paid enrichment merely because this skill is active. Use it when the requested scope and missing evidence justify it; keep simple answers simple.
Infer scope, dates, geography, audience and output; ask only for decisions that materially change the investigation. Convert relative dates to explicit bounds. For substantial investigations, briefly state the main questions, evidence routes, then begin. Revise the questions as findings reveal consequential gaps or competing explanations.
Use firecrawl_search with the actual question and its constraints to find sources, or the dedicated method below when the evidence calls for it, such as papers, code or US law. Read supplied URLs with firecrawl_scrape. Inspect relevant page results and matching capability suggestions returned by search.
When firecrawl_search exposes objective, set it to [deep-research] followed by the broader research goal, keeping that goal consistent across related searches. Keep query focused on the specific evidence needed, without the marker. Omit objective if the live schema does not support it, and avoid sensitive information in the goal.
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.

firecrawl-deep-research is a skill published in the GitHub repository firecrawl/firecrawl-claude-plugin (247 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 2,320 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-26.
Other skills, from other repositories
firecrawl-search
Find web sources with query-relevant page excerpts and optional full-page content, and discover workflows, data APIs, and indexes. Use for web research or finding structured records, listings, transcripts, and datasets. Supports semantic tool discovery, domain matching, and progressive catalogue browsing.
firecrawl
Any live-web task via the Firecrawl CLI — including ordinary web research: searching the web, reading or extracting pages, gathering sources, discovering site URLs, bulk extraction, downloading a site, change alerts, or pages needing clicks/login — web only; local files route to firecrawl-parse. For US legal or…
firecrawl-scrape
Read a known webpage or execute a discovered workflow or data-provider capability. Use for page content or structured results once the URL or tool is selected.
firecrawl-alexandria
Find a direct path to structured data through ready-made workflows, data APIs, and indexes. Follow the search skill to discover and inspect tools, then the scrape skill to execute them.
firecrawl-agent
Autonomously navigate websites and extract structured data across pages. Use when the task requires navigation or no suitable ready-made workflow or data provider covers it.
firecrawl-monitor
Alert by webhook/email on web changes — use for "monitor/watch/track/alert me when": recurring checks on known URLs (prefer over repeated one-off scrapes) or web-wide watches for new results (queries + goal).
