Diagnoses a Percona Server for MySQL 8.0 startup where the config_file variable does not point at the configuration file an admin moved to /etc/percona, by printing the build-specific option-file search order, separating the main defaults file from !includedir merges, and running a sentinel-value test. Use when config…
Shows how to design a read-only service API with modular least-privilege scopes: one scoped service token per module, read-only enforcement at route, scope and data layers, published-only filtering inside the base query, allowlist response projection for user privacy, and coarse opt-in handling for presence data. Use …

Fixes MySQL 'Too many connections' by finding connection leaks, tuning max_connections safely, and adding pooling. It covers the memory cost of raising the limit. Not for authentication errors.
Fixes Postgres connection exhaustion during dbt runs for analytics engineers and repair agents. Use when Postgres reports too many clients already. Not for slow queries or auth failures.

For sales-outreach (SDR) agents: Every wait needs a deadline and every deadline needs a next step. Set explicit timeouts on external calls, treat a timeout as 'unknown outcome' (not failure), and reconcile before retrying anything with side effects.
Fixes Airflow scheduler stalls from SQLAlchemy pool exhaustion: pool sizing versus scheduler threads and database capacity. Use when the scheduler sticks with pool timeout errors. Not for slow queries on a healthy pool.
Fixes Dagster daemon crashes from Postgres run storage refusing connections: Postgres availability, connection limits, and storage config. Use when the daemon crashes with connection refused to Postgres. Not for slow queries on a reachable Postgres.
Fixes httpx ReadTimeout on reused keep-alive connections: stale-connection handling, pool limits, and timeout tuning. Use when the first ~100 requests succeed and later ones time out on read. Not for DNS failures or target-site rate limiting.
A guide to fixing KB search agents that return empty results on valid queries, in the business-apis-integrations category: query expansion, typo tolerance, and graceful fallback. Use when the search agent finds nothing for queries the KB clearly covers, or when tuning search recall. Not for building the search index, …

Fixes Vectorize 'topk too large' query errors. Use when vector queries request too many results. Key trigger: the topk-too-large error.
Fixes ffuf aborting with too many errors during authorized directory fuzzing. Use when ffuf stops early because the error rate crossed its threshold. Not for runs that complete with zero results.
Confirms TIME_WAIT socket pileups with connection-state counts, then fixes the real cause first (connection reuse and keep-alive) before tuning kernel settings like the TIME_WAIT reuse knob or the ephemeral port range. Use when clients or proxies hit 'cannot assign requested address' under high connection churn. Not f…
