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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 73 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00091 | $0.01891 |
| Opus 5 | $0.00046 | $0.00945 |
| Sonnet 5 | $0.00018 | $0.00378 |
| Haiku 4.5 | $0.00009 | $0.00189 |
Grade A, and why
ring:using-runtime 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 5d 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.

ring:using-runtime
Moved from lib-commons
The runtime package lived in lib-commons through v4 and the v5 shim period.
Its canonical home is now github.com/LerianStudio/lib-observability/runtime (v1.0.0+).
lib-commons v5 keeps a deprecated compatibility shim at
github.com/LerianStudio/lib-commons/v5/commons/runtime that re-exports every symbol
from lib-observability — existing imports keep compiling, but the shim is marked
Deprecated: in package docs and will be removed in a future lib-commons major. New
code MUST import from lib-observability/runtime directly; sweeps SHOULD also flag
imports still pointing at the lib-commons shim as a follow-up migration.
When to use
Sweep mode:
- "Sweep / audit panic handling"
- "Find naked goroutines"
- "Migrate this service to lib-observability/runtime"
- "Are our defer recover() calls observable?"
Reference mode:
- "Which SafeGo variant do I use for X?"
- "How does the observability trident fire on panic?"
- "Show me the policy decision tree"
- "How do I wire runtime into Fiber / gRPC / RabbitMQ?"
Skip when
- Working on non-Go services
- Working on frontend code

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.

ring:using-runtime is a skill published in the GitHub repository LerianStudio/ring (211 stars, last pushed 19d ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,891 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
