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.

What it costs to keep this loaded
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 | $0.00044 | $0.00348 |
| Opus 5.5 | $0.00018 | $0.00139 |
| Sonnet 5.5 | $0.00009 | $0.00070 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
openskills-runtime-debug 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 1mo 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
OpenSkills Runtime Debug
Use this skill when debugging runtime failures in runtime/ and execution paths used by run_skill_target, native scripts, or sandbox enforcement.
Primary Targets
runtime/src/executor.rsruntime/src/native_runner.rsruntime/src/wasm_runner.rsruntime/src/permissions.rsruntime/tests/*sandbox*runtime/tests/seatbelt_tests.rs
Workflow
- Reproduce with the smallest command that fails.
- Classify failure bucket:
- sandbox policy issue
- feature/config mismatch
- script/tool resolution issue
- wasm runtime issue
- Confirm behavior against tests and existing fallback logic.
- Propose the smallest safe fix that preserves security boundaries.
- Re-run focused tests, then broader runtime tests.
Recommended Commands
cargo check -p openskills-runtime
cargo test -p openskills-runtime
cargo test -p openskills-runtime seatbelt_tests -- --nocapture
Debug Heuristics
- Treat silent degradation in sandbox setup as high risk.
- Prefer explicit error propagation over ignored
Result. - If fallback behavior is intentional, confirm it is visible in logs and tests.
- Keep macOS and Linux behavior differences explicit in findings.
Output Format
Return:
- Root cause
- Impact surface
- Fix proposal
- Verification evidence
- Residual risks
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.

openskills-runtime-debug is a skill published in the GitHub repository Geeksfino/openskills (71 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 348 once invoked, about $0.0002 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 2026-08-30.
