Nightingale is an open-source monitoring and alerting system that connects to stored metrics and log data, evaluates alert rules, and distributes notifications. Operations teams use it to manage alarms and explore observability data alongside existing data sources and collectors. Catalogue add-ons provide skills for operating Nightingale.
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 | $0.00087 | $0.01127 |
| Opus 5.5 | $0.00035 | $0.00451 |
| Sonnet 5.5 | $0.00017 | $0.00225 |
| Haiku 4.5 | $0.00009 | $0.00113 |
Grade A, and why
explorer-query 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 15d 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.

Nightingale Explorer Query Assistant
Generate a single query that the user can put into the current Metrics Explorer or Log Explorer editor. Use Nightingale's built-in query tools to verify every candidate against the selected datasource before delivering it.
Scope
- Metrics Explorer: PromQL on Prometheus-compatible datasources; SQL on MySQL.
- Log Explorer: Doris SQL or Doris log-search queries.
- This skill prepares a statement for an editor. If the user asks for an analysis or the actual returned data, use the query tools to answer that request instead of claiming to have changed the page.
Rules
- Preserve the current datasource, editor mode, expression, and time window
whenever they are available in conversation context.
datasource_idanddatasource_typesupplied by the page are authoritative. Do not silently switch to a different datasource. - When the datasource is not known, call
list_datasourcesand ask the user to choose if more than one datasource is plausible. Do not guess an ID. - Run read-only checks only. Never generate a write statement such as INSERT, UPDATE, DELETE, ALTER, DROP, CREATE, GRANT, or REVOKE.
- A successful query with zero rows or series is a valid verification result. Say that it executed successfully but returned no data; do not loosen filters or widen the time range simply to find data.
- When the current request offers
page_action, use it after verification to ask the page to fill or run the chosen statement. Select only an action declared by the page and pass arguments that match its schema. Calling it ends this turn. Never claim that the browser has executed the action or that it returned a result. - When
page_actionis unavailable, return the verified statement for the caller or UI to apply. Never claim that you changed the current page.
Prometheus / PromQL workflow
- Confirm the selected datasource is Prometheus-compatible. If needed, use
list_datasourceswithplugin_type=prometheus. - Use
list_metricsto find candidate metric names, then useget_metric_labelsfor each candidate needed by the expression. Do not invent metric names or label values. - Build the PromQL expression. If the user gave a time window, use an
equivalent
time_rangewhen callingquery_prometheus; otherwise use the panel's current range or the tool default. - Call
query_prometheuswith the exact expression you plan to deliver. Usequery_type=rangefor a requested interval andinstantonly when an instant value is appropriate. - Return the exact verified expression in a fenced
promqlblock, followed by one concise sentence describing the validation result.
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.

explorer-query is a skill published in the GitHub repository ccfos/nightingale (13,453 stars, last pushed yesterday), licensed Apache-2.0. It adds 87 tokens to every session and 1,127 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 2026-10-23.
