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 | $0.00031 | $0.00256 |
| Opus 5 | $0.00015 | $0.00128 |
| Sonnet 5 | $0.00006 | $0.00051 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
attack-tree-construction 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 9d 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.
This is a copy
97% identical to attack-tree-construction — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Attack Tree Construction
Systematic attack path visualization and analysis.
Use this skill when
- Visualizing complex attack scenarios
- Identifying defense gaps and priorities
- Communicating risks to stakeholders
- Planning defensive investments or test scopes
Do not use this skill when
- You lack authorization or a defined scope to model the system
- The task is a general risk review without attack-path modeling
- The request is unrelated to security assessment or design
Instructions
- Confirm scope, assets, and the attacker goal for the root node.
- Decompose into sub-goals with AND/OR structure.
- Annotate leaves with cost, skill, time, and detectability.
- Map mitigations per branch and prioritize high-impact paths.
- If detailed templates are required, open
resources/implementation-playbook.md.
Safety
- Share attack trees only with authorized stakeholders.
- Avoid including sensitive exploit details unless required.
Resources
resources/implementation-playbook.mdfor detailed patterns, templates, and examples.
What ships with it
1 file 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.

attack-tree-construction is a skill published in the GitHub repository benjaminasterA/antigravity-awesome-skills (256 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 256 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to attack-tree-construction, differing in 4 lines, and is treated as a copy.
