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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.00581 |
| Opus 5 | $0.00034 | $0.00291 |
| Sonnet 5 | $0.00014 | $0.00116 |
| Haiku 4.5 | $0.00007 | $0.00058 |
Grade A, and why
opencrow-web-toolbox 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 8d 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.
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 — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenCROW Web Toolbox
Runtime preflight
Probe required commands with command -v and Python modules with importlib.util.find_spec before use. Prefer a PATH-resolved OpenCROW MCP helper or the ctf/sage environment when available, then the managed helper or system Python. If a capability is missing, stop that path safely and report the exact missing command or module.
Use this skill for web CTF work that starts from discovery and fuzzing rather than browser automation: sqlmap, gobuster, ffuf, dirb, and wfuzz. The full installer profile also tracks manual acquisition steps for Burp Suite Community and OWASP ZAP.
Quick Start
Start the MCP server from the installed CLI:
opencrow-web-mcp
Verify the mapped stack:
python3 scripts/verify_toolkit.py
Workflow
- Start with endpoint and content discovery using
ffuf,gobuster, ordirb. - Use
wfuzzwhen the problem is parameter fuzzing or more custom request mutation. - Use
sqlmapwhen the challenge is plausibly SQLi-driven and the target is stable enough for automation. - Use
playwrightseparately when the task needs a real browser or a JS-heavy flow. - If a full profile was installed, use the manual Burp/ZAP links from the installer summary for GUI-heavy workflows.
- Prefer the MCP server operations first:
toolbox_info,toolbox_verify,toolbox_capabilities,web_discover,web_fuzz, andweb_sqlmap_scan.
Tool Selection
- Use
ffuffor fast fuzzing against paths, parameters, or virtual hosts. - Use
gobusterfor straightforward wordlist-driven discovery. - Use
dirbwhen a challenge guide or prior workflow already assumes DIRB-style usage. - Use
wfuzzwhen request templating matters more than raw speed. - Use
sqlmapwhen the target and request shape are stable enough to automate.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

opencrow-web-toolbox is a skill published in the GitHub repository 02loveslollipop/OpenCROW (8 stars, last pushed yesterday), licensed Apache-2.0. It adds 69 tokens to every session and 581 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
