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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00207 |
| Opus 5 | $0.00000 | $0.00103 |
| Sonnet 5 | $0.00000 | $0.00041 |
| Haiku 4.5 | $0.00000 | $0.00021 |
Grade B, and why
digest scanned grade B 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Markdown file at the chosen path (chmod 600). What it actually says
core/digest
Generate a compact markdown digest of the local Arena Agent state — suitable for pasting into a brand-new Arena.ai chat to bootstrap context fast.
Inputs
- argv[1] (optional): output file path. Default:
~/arena-bridge/reports/digest-<UTC>.md.
Outputs
- Markdown file at the chosen path (chmod 600).
- The absolute path is printed to stdout.
- Sections included:
- generated timestamp + hostname
- bridge health + service state (short)
- current project (if any)
- last 8 memory facts
- last task summary
- last 5 reports (file names only)
- last 10 chat sessions (file names only)
- top-level command groups (chat / project / task / browser / recon / memory / skill)
Notes
- Read-only. Safe to run any time.
- Designed to fit comfortably in a single Arena message (target < 6 KB).
What ships with it
3 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.

digest is a skill published in the GitHub repository IvanSkainet/arena-agent (6 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 207 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
