“#2 📝 Armin Ronacher Better Models: Worse Tools - Newer Anthropic Claude models (Opus 4.8 and Sonnet 5) sometimes call Pi’s edit tool with extra invented fields inside edits[]—examples observed include requireUnique, oldText2/newText2, type, event.0.additionalProperties—causing Pi to reject the call even though oldText/newText were correct; in one reproduced session Opus 4.8 failed about 20% of the time, stripping “thinking” blocks halved the failure rate, and strict tool invocation eliminated it.”

#2 📝 Armin Ronacher Better Models: Worse Tools - Newer Anthropic Claude models (Opus 4.8 and Sonnet 5) sometimes call Pi’s edit tool with extra invented fields inside edits[]—examples observed include requireUnique, oldText2/newText2, type, event.0.additionalProperties—causing Pi to reject the call even though oldText/newText were correct; in one reproduced session Opus 4.8 failed about 20% of the time, stripping “thinking” blocks halved the failure rate, and strict tool invocation eliminated it. The author hypothesizes this is a training/post-training artifact from reinforcement in a forgiving Claude Code harness (with retries, aliases and repairs) that rewards sloppy but successful tool calls, making newer models worse at adhering to alternative tool schemas than older models like Opus 4.5.

Anthropic also published an early draft jailbreak severity framework with Glasswing, launched a HackerOne program and feedback channel (cyber-safeguards@anthropic.com) for reporting cyber jailbreaks, and enumerated prohibited actions such as ransomware, cyber‑physical sabotage, AV/EDR bypass, command‑and‑control, data exfiltration, malware development/propagation, and internet backbone attacks.

The repo also provides a dev-server skill with ensure-dev-server.sh (which ensures .env.local and secrets AMP_API_KEY_SECRET, THREAD_ACTORS_SERVICE_SECRET, THREAD_ACTORS_WEBSOCKET_JWT_SECRET, and can reuse/restart/start the server), writes .amp/dev-ports.json, and exposes /__dev endpoints (including /__dev/log-me-in/ , /__dev/sudo, /__dev/preflight) so agents can autonomously start, authenticate to, and verify the dev environment and produce screenshots/results in minutes. #11 📝 Ampcode Chronicle Read Bigger Threads - Amp rewrote read_thread into a dedicated subagent (now running GLM 5.2 instead of Gemini 3.5 Flash) that searches long threads, verifies whether edits actually succeeded, and explicitly checks for newer messages that revise, supersede, or revert earlier hits. The change was driven by compaction making threads huge—one thread would be ~21 million tokens without compaction and has been compacted over 68 times—and the subagent uses compactions for orientation but inspects original messages when exact wording, code, chronology, or verification matter. #12 📝 Simon Willison llm-coding-agent 0.1a0 - Simon shipped an early alpha of a new Python coding agent built on his LLM/agent framework, created via Claude Fable 5 and released to PyPI and GitHub. The post describes the prompts, spec, README, available tools, and a demo transcript showing the agent generating a simple Swift CLI ASCII clock. #13 📝 Simon Willison Using DSPy to evaluate and improve Datasette Agent's SQL system prompts - Simon experimented with dspy to evaluate and improve the system prompts used by Datasette Agent for read-only SQL queries, firing off an asynchronous research task using Claude Fable 5.

Claude Fable 5 is available on Claude subscriptions until July 7 with a 50% weekly usage cap, after which it switches to pay-as-you-go API credits. Fable 5 audited a vibe-coded fitness app via five parallel agents, running all unit tests and identifying over 12 major bugs including a user-data leak on involuntary sign-out. Fable 5 drafted a detailed HTML plan for a new nutrition-tracking tab—complete with UI mockups, Supabase schema, and USDA FDC API integration—using the Lavish editor plugin. #22 ▶️ Fable 5 vs GPT 5.6 Sol: The Early Results AI Explained GPT 5.6 Soul is benchmarked against Anthropic’s Fable 5 (Mythos 5) on Terminal Bench 2.1, Healthbench Professional, and Exploit Bench, with GPT 5.6 Soul scoring almost 92% vs 88% on Terminal Bench, 60.5% (64% length-adjusted) vs 66.0% on Healthbench, ≈76% vs ≈78% on Exploit Bench, and costing half the API input price and just over half the output price of Fable 5. GPT 5.6 Soul on Terminal Bench 2.1 ultra mode scored almost 92% compared to Mythos 5’s 88%. On Healthbench Professional, Mythos 5 scored 66.0% raw horsepower versus GPT 5.6 Soul’s 60.5% (64% length-adjusted).
