Shows how to encrypt and decrypt bytes with AES in pycryptodome through Crypto.Cipher.AES: generate a 16, 24, or 32 byte key with get_random_bytes, encrypt with AES-GCM using encrypt_and_digest, store nonce, ciphertext, and tag together, and decrypt with decrypt_and_verify, plus the CBC pad and unpad variant. Use when…
Shows how to support non-expiring opaque API tokens safely: model expiration as an explicit policy instead of a bare nullable timestamp, require a recorded opt-in with a reason, fail closed on inconsistent rows, and migrate legacy tokens whose null expiration has unknown intent instead of silently making them immortal…
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 …
Shows how to build named opaque API tokens in ASP.NET Core: issue a prefixed random token once, store only its hash, authenticate it in a dedicated scheme, scope and revoke it per endpoint, and add per-token rate limiting and usage aggregates. Use when replacing shared bearer secrets with revocable per-client tokens. …
Shows how to build an approval workflow in ASP.NET Core with EF Core where a submitted revision is an immutable snapshot, optimistic concurrency stops overwrites, and notifications are written to a transactional outbox in the same transaction as the submit and published afterwards. Use when approvers must approve exac…
Fixes the Help center search problem where Old feature name search returns no results after rename by applying the specific fix in the steps, proving it on one article, collection or query first, then confirming readers see the correction. Use when this exact symptom blocks readers or agents in the help center. Not fo…

Tells an agent client exactly how to handle an HTTP 503 with error code temporarily_unavailable from an API like Vectle search: do not replay the identical request, check the retry fields, wait, and start a deliberate new request only if still needed. Use when a call returns 503 temporarily_unavailable or a body whose…
Sets out rate-limit etiquette for agents sharing public infrastructure: read the limit signals, back off exponentially with jitter, batch and cache reads, and stop hammering during incidents. Use when an agent client hits 429 responses or degraded-status headers on a shared API. Not for negotiating higher quotas, and …

Fixes a Salesforce Bulk API InvalidBatch failure when syncing account health fields to the CRM, by finding the bad batch, query, or payload behind it. Use when a bulk health sync partially fails. Not for single-record API update errors.
Builds an authenticated EF Core employee directory that returns only a minimal public DTO: exclusion of blocked and system accounts before search and counting, server-side Select projection with no admin fields, an allowlisted sort with an id tie-breaker, and clamped pagination. Use when a directory endpoint returns u…

Fixes a patch agent whose preflight fails because the asset inventory query times out, where a broad CMDB query (whole fleet, many fields, unindexed filter) cannot return inside the agent timeout. Use when preflight dies at the inventory step on large fleets. Not for inventory service outages.
Fixes fraud agents that fail on Onfido webhook payloads: validates against the current Onfido webhook event schema, handles check completed and check result fields as delivered, and logs raw payloads for schema drift. Use when Onfido webhooks error in the agent while the dashboard shows completed checks. Not for missi…
Handles a triage run failing when the mailbox search API returns empty results mid-campaign, by distinguishing a true empty result from a failed or malformed query. Use when search-based sweeps intermittently return zero results for mail known to exist. Not for mailboxes that genuinely contain no matching mail.
