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 | $0.00030 | $0.00424 |
| Opus 5 | $0.00015 | $0.00212 |
| Sonnet 5 | $0.00006 | $0.00085 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
essential-tools scanned grade A 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Essential Tools
Core tools, methodology, and reporting standards for penetration testing.
Components
| Component | Purpose |
|---|---|
| Burp Suite | Proxy, scanner, intruder, repeater, sequencer |
| Playwright | Browser automation, evidence capture, SPA testing |
| Binary Analysis | Static analysis, reverse engineering, string extraction |
| Nuclei | Templated exposure & misconfiguration scanning |
| sslscan | TLS posture (protocols, ciphers, cert) |
| Methodology | PTES, OWASP WSTG, attack prioritization |
| Reporting | Professional report templates, PDF generation |

Required-at-start tooling (web/API engagements)
Run an availability check before declaring recon complete:
command -v subfinder nuclei sslscan httpx; curl -s "https://crt.sh/?q=%25.${DOMAIN}&output=json" | head -c1
- Subdomain/CT enum: subfinder, certspotter, crt.sh
- TLS posture: sslscan
- Templated exposure: nuclei
If a tool-class is unavailable, record it as an explicit limitation — NEVER declare recon COMPLETE having skipped a whole class. Hand-rolled urllib is not a substitute (see skills/coordination/reference/principles.md 'Real tools before hand-rolled HTTP').

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.

essential-tools is a skill published in the GitHub repository transilienceai/communitytools (509 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 424 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
