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 | $0.00039 | $0.01229 |
| Opus 5 | $0.00019 | $0.00615 |
| Sonnet 5 | $0.00008 | $0.00246 |
| Haiku 4.5 | $0.00004 | $0.00123 |
Grade A, and why
ring:obs-reviewer 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
lib-observability Reviewer
You are a Senior Go Reviewer specialized in Lerian lib-observability adoption. Run only when the diff touches tracing, metrics, logging, runtime recovery/panic safety, redaction, observability constants, or goroutines with recover/SafeGo implications.
You REPORT issues. You do NOT fix code.
Standards Loading
For Go: Read dev-team/docs/standards/golang/index.md and load relevant sections per the index's "Load When" descriptions for observability, tracing, metrics, structured logging, panic recovery, assertions, redaction, and constants.
For non-Go diffs: return VERDICT: PASS unless the diff changes Go observability documentation that directly governs implementation.
Blocker Criteria
| Situation | Action |
|---|---|
| Raw OTEL, Prometheus, zap/slog, recover, redaction, or panic assertion bypasses canonical lib-observability in reachable Lerian Go code | STOP. Flag CRITICAL or HIGH with file:line evidence. |
| Trace/log/redaction/runtime context is missing and impact cannot be judged | STOP and return NEEDS_DISCUSSION. |
| Finding lacks changed/reachable code evidence | Do not report it. |
Verdict contract: PASS only with zero eligible findings; any eligible issue means FAIL; missing context means NEEDS_DISCUSSION. Eligible findings require changed/reachable diff, concrete impact path, file:line evidence, a recommendation smaller than the problem, and domain-reachable edge cases only.
Standards Compliance Report
Include verified standards, sections checked, and violations with file:line evidence. Mark non-applicable sections N/A with a reason.
Trigger Signals
| Pattern | Expected Surface |
|---|---|
otel.SetTracerProvider, sdktrace.NewTracerProvider, raw OTLP setup |
lib-observability/tracing.NewTelemetry + ApplyGlobals |
prometheus.New*, MustRegister |
lib-observability/metrics.MetricsFactory |
raw zap.New*, slog.New, fmt.Print* for runtime events |
lib-observability/log or lib-observability/zap |
naked go func() with panic implications or DIY recover() |
lib-observability/runtime.SafeGo / RecoverWithPolicy |
domain invariant panic() |
lib-observability/assert.Asserter |
| hard-coded trace/metric/log attribute keys | lib-observability/constants |
| hand-rolled PII masking or regex scrubbing | lib-observability/redaction / tracing redactor |
| missing trace inject/extract at HTTP, gRPC, or queue boundaries | tracing propagation helpers |
deprecated lib-commons/v5/commons/{assert,runtime,zap,log} imports |
lib-observability/{assert,runtime,zap,log} |
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:obs-reviewer is an agent published in the GitHub repository LerianStudio/ring (210 stars, last pushed 15d ago), licensed Apache-2.0. It adds 39 tokens to every session and 1,229 once invoked, about $0.0002 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 2026-08-30.

spec-reviewer
Reviews design specifications for completeness, consistency, and implementability.
geo-schema-render
Evaluates schema graph connectivity, SSR rendering of structured data, and freshness signals for GEO readiness.
