AI HarnessManaging Prompt Templates Across a Harness CodebaseFour divergent copies of one prompt caused a two-day bug. Harness prompt templates management makes prompts versioned, tested, single-source artifacts instead of scattered strings.September 10, 2026·8 min read
AI HarnessHow to Open-Source Your Agent HarnessAn agent harness isn't an ordinary library — it's security-sensitive infra tangled with your secrets. Release an open source agent harness without leaking a key or shipping unusable code.September 10, 2026·8 min read
AI HarnessError Taxonomy: Classifying Harness FailuresWhen every failure looks the same, you can't retry, route, or alert correctly. Agent harness error classification gives failures types that drive real behavior.September 10, 2026·8 min read
AI HarnessBuilding a CLI Around Your Agent HarnessA useful agent nobody could run became one everyone uses — the fix was a real agent harness cli with stdin, clean stdout, and meaningful exit codes.September 10, 2026·8 min read
AI HarnessHandling Streaming Tool Calls in the HarnessModel tool calls arrive as partial fragments, not complete blocks. Harness streaming tool calls is the art of buffering, assembling, and validating them before you execute.September 10, 2026·8 min read
AI HarnessDeterministic Replay for Harness DebuggingAn agent bug you can't reproduce is a bug you can't fix. Harness deterministic replay records every non-deterministic result and replays a run byte-for-byte on demand.September 9, 2026·9 min read
AI HarnessHow to Benchmark Two Harnesses Head-to-HeadSuccess rate alone hides cost and picks wrong. A proper agent harness benchmark runs many trials, measures cost per success, and isolates the harness from the model.September 9, 2026·8 min read
AI HarnessInstrumenting a Harness With OpenTelemetryAn agent run is already shaped like a trace. Agent harness opentelemetry turns an undebuggable multi-service run into a span-by-span tree you can inspect in minutes.September 9, 2026·8 min read
AI HarnessBuilding a Dry-Run Mode for Your HarnessSee exactly what an agent would do before it touches production. An agent harness dry run runs the full loop, simulates mutating tools, and hands you the plan to review.September 9, 2026·8 min read
AI HarnessTesting Your Harness Against Prompt InjectionInjection resistance is something you measure, not assert. Harness prompt injection testing attacks your own agent with a corpus of payloads in CI before someone else does.September 9, 2026·8 min read
AI HarnessMulti-Tenant Agent Harness DesignOne tenant's batch job starved everyone; a keying bug leaked another's data. A multi tenant agent harness makes isolation structural: namespaced state, scoped creds, fair scheduling.September 9, 2026·8 min read
AI HarnessResuming an Interrupted Agent RunRetrying a failed run repeats every side effect it already committed. A resume agent run harness continues from the last step instead — with journaling and idempotency keys.September 9, 2026·8 min read
