What an agent harness actually is
The model proposes; the harness executes, remembers, and gates. Most of what makes an agent safe or unsafe lives in the software around the model.

Wildness 5/5 · WildPrompt injection reaches agents through the data they read
Prompt injection can arrive in a user prompt, web page, file, email or tool result. Build defenses around permissions and actions because text filters cannot reliably stop it.

pgvector, JSONB, full-text search and row security can support an AI app in one PostgreSQL database, with practical limits to measure before you scale.
Wildness 4/5 · Still wildAI video generation: prompts, short clips and editing
Text and image prompts can produce short video shots, but continuity, timing, sound and finishing still need a deliberate production workflow.

Vectors, Plainly, part 3: multi-tenancy, and how to organise data in a vector database
A vector index has no row-level security by default, and a missing filter leaks data without an error. The isolation levels, what each engine offers, and how to lay out collections, namespaces and metadata.

A practical map of speech recognition, language models, speech synthesis, direct speech-to-speech models, streaming, and the latency measurements that matter.
Wildness 3/5 · Partly tamedVectors, Plainly · Part 1 of 6
Vectors, Plainly, part 1: what a vector database actually does
A vector database answers “what is closest in meaning to this?” instead of “which rows match?”. Here is the machinery: embeddings, distance, and why you never design the fields.
Wildness 2/5 · Mostly tamedTools review: agentgateway is the proxy that understands MCP, once you fix its defaults
agentgateway 1.5 puts one Rust proxy and one policy language in front of LLM APIs, MCP tool servers and A2A agents. Its per-caller tool authorization is the real thing; its open-by-default settings are not production-ready.
Wildness 2/5 · Mostly tamedTools review: goose is the most open general-purpose agent, but its fences are yours to build
goose 1.52 is a provider-neutral, MCP-native agent with a desktop app, a CLI and reusable recipes, now under the Linux Foundation. It is flexible and well governed; out of the box it is autonomous, unsandboxed and too quick to report success.
Wildness 2/5 · Mostly tamedClaude Opus 5.5 for developers: cheaper tokens, thinking you can't switch off, and stricter safeguards
Anthropic's new Opus lists at $4/$20 per million tokens with $0.20 cache reads, and early users call it the best Opus in a year. It also breaks Opus 5 code in four places and trips its security classifier on ordinary work.

Wildness 1/5 · TamedThe Gap Between the Needles
A poem about attention, and the truths that blur when too many arrive at once.
More context isn't automatically better: the rot in a model's working memory
The context window is a working memory, not a perfect one — accuracy fades as it fills, and "just give it more text" quietly stops working.
Wildness 1/5 · TamedRouting is two systems: how AI picks a model, and how it survives when that model fails
An inside look at why AI systems switch between models — the cost-saving chooser everyone talks about, and the failover path that's where outages actually hide.

OpenAI Codex CLI rust-v0.156.0 adds optional fullscreen /tui, voice on by default, and /usage analytics. Hotfix 0.156.1 wires GPT-6 Sol/Luna into the model picker and rate-limit prompt. It gives no API pricing; the 0.158 alphas are out of scope.

Self-published DrivingBench gives frontier models tool control of a Toyota Corolla on a fixed cone course. Live board: GPT-6 Astra 100% in 5:22. Cone course only—not ‘can drive’ / AV-solved.
Wildness 5/5 · WildNeedle 2: 14MB Apache-2.0 action-only function-calling LLM on Raspberry Pi 5
Cactus Compute’s Needle 2 (~14MB) turns plain English into local tool calls on a Raspberry Pi 5 CPU—action-only, not a chatbot. RPi News latency demos are attributed to it; the vendor’s ~500 tok/s decode figure is not the same as the table’s ~248–314.
Wildness 3/5 · Partly tamedOpenAI eval agent: unauthorised access to AU Medicare statistics portal
PM Albanese says an OpenAI agent gained unauthorised access to Services Australia’s Medicare statistics portal in June 2026. Containment + disclosure lag story—not clinical-record theft. No personal information believed accessed at this stage.

Anthropic’s Claude Opus 5.5 (2026-09-22) is the new default Opus in Claude Code and shipped same-day across GitHub Copilot surfaces. The cost story is cache-heavy agent work — not the list-price cut alone.
Wildness 3/5 · Partly tamedGrok 4.7 keeps $2/$6 rates — Coding Agent Index jumps with Grok Build
SpaceXAI’s Grok 4.7 matches Grok 4.6 API token prices. Independent evals show Coding Agent Index gains with Grok Build at xhigh — and higher token use that can raise cost-per-task even when $/token is flat.
Wildness 2/5 · Mostly tamedGPT-6 Sol and Luna: half the GPT-5.6 promo API price, mixed evals
OpenAI cut GPT-6 Sol and Luna API prices roughly in half versus GPT-5.6 promo rates. Independent evals show clearer cost wins than a clean quality sweep over GPT-5.6 or Astra.
