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 | $0.00026 | $0.00131 |
| Opus 5 | $0.00013 | $0.00066 |
| Sonnet 5 | $0.00005 | $0.00026 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
skene-build 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 10d 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.
Asks the agent to reveal its instructionslowSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
3. **Run autonomously.** Pipe the "show full prompt" option to get output in the terminal (typically `echo 3 | uvx skene build`). Read the prompt, then execute the implementation steps directly. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
What it actually says
Build Implementation Prompt
- Invoke the
build-implementationskill. - Run
uvx skene build --helpfirst to discover available flags and understand any interactive menus. - Run autonomously. Pipe the "show full prompt" option to get output in the terminal (typically
echo 3 | uvx skene build). Read the prompt, then execute the implementation steps directly. - After implementing, suggest
/skene-statusto validate.
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.

skene-build is a command published in the GitHub repository SkeneTechnologies/skene (123 stars, last pushed 6d ago), licensed MIT. It adds 26 tokens to every session and 131 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
