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 | $0.00017 | $0.03232 |
| Opus 5 | $0.00009 | $0.01616 |
| Sonnet 5 | $0.00003 | $0.00646 |
| Haiku 4.5 | $0.00002 | $0.00323 |
Grade B, and why
web-pentest scanned grade B with 3 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 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.

One request to 169.254.169.254 can return temporary IAM credentials.

How it starts
The opening of the file, as written. The whole thing — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Application Penetration Testing
A phased pentesting workflow for running web applications. Adapted from Shannon's pipeline (Keygraph, AGPL — concepts only, no code borrowed). Built around three rules:
- No exploit, no report — every finding requires reproducible evidence.
- Bounded scope — every active request goes against a target the operator pre-declared. Off-scope hosts are refused.
- Bypass exhaustion before false-positive dismissal — a "blocked" payload is not a clean bill of health until you've tried the bypass set.
⚠️ Hard Guardrails — Read Before Every Engagement
Violating any of these invalidates the engagement and may be illegal.
-
Authorization gate. Before the first active scan in a session, you MUST confirm with the user, in writing, that they own or have written authorization to test the target. Record the acknowledgement in
engagement/authorization.md(see template). No acknowledgement → no active scanning. Reading public pages withcurlis fine; sending payloads is not. -
Scope allowlist. Maintain
engagement/scope.txt— one hostname or CIDR per line. Everynmap,curl,whatweb, browser navigation, or payload-bearing request MUST be against an entry in scope. If a target redirects you off-scope (3xx to a different host, a link in HTML), STOP and confirm with the user before following. -
No production systems without paper. If the user hasn't told you "yes, prod is in scope and I have written sign-off," assume not. Default targets are staging, local docker, dedicated test instances.
-
Cloud metadata is off by default. Do not probe
169.254.169.254,metadata.google.internal,100.100.100.200,[fd00:ec2::254], or equivalent unless the engagement explicitly includes SSRF-to-metadata as a goal AND the target is one you control. The agent's browser tool can reach these from inside your own infrastructure — don't. -
Destructive payloads need approval. SQLi payloads that DROP/DELETE, filesystem-write SSTI, command injection with
rm/shutdown/mkfs, anything that mutates beyond a single test row → ASK FIRST. Theapproval.pysystem catches some; don't rely on it alone.

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.

web-pentest is a skill published in the GitHub repository aivrar/portable-hermes-agent (217 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 3,232 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 3 findings (cloud metadata endpoint, makes network calls, runs shell commands). It is 100% identical to web-pentest, differing in 0 lines, and is treated as a copy.

Map of Hope Agent's local data stores and safe read-only query workflow. Use when the user asks where Hope Agent stores data, wants to inspect sessions/messages/memory/logs/background jobs/knowledge indexes/settings, asks the model to query local app data, or debugging requires checking persisted state.
