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 | $0.00072 | $0.00284 |
| Opus 5.5 | $0.00029 | $0.00114 |
| Sonnet 5.5 | $0.00014 | $0.00057 |
| Haiku 4.5 | $0.00007 | $0.00028 |
Grade A, and why
solidity-audit 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 2mo 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.
What it actually says
Solidity audit
Kit-owned. Edit in the harness-kit repo, not in the consumer repo.
Security review of contracts. Produces findings; fixes are separate solidity-build contracts.
When to use
Auditing smart contracts for security, before a deployment or an external review.
When not to use
Implementing or fixing contracts → a solidity-build sprint contract.
General code quality → code-audit.
Rules that matter
- PoC first. High and Critical findings need a reproducible verify command. An unreproducible Critical claim is unverified, not a finding.
- Record the exact commit or tag audited, and what is explicitly out of scope.
- Run the Solidity section of
security-checklistagainst the target. - Assign finding IDs; keep severity honest against the declared rubric.

What ships with it
2 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.

solidity-audit is a skill published in the GitHub repository David405/harness-kit (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 72 tokens to every session and 284 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
