The bug report feed for @ClaudeDevs @AnthropicAI is pure comedy for devs and the best echo chamber for frustrated users. github.com/anthropics/cla…

@steipete @waldekm Caveman

Folks: when you write skills, ask your agent to be token efficient, relax grammer. I see too many skills that write books in the skill description, and all that crap is loaded into every context. I wrote a skill that finds the worst offenders. github.com/steipete/agent…

The origin story for @gnome is pretty amazing. @migueldeicaza and Federico Mena changed the world and don’t get enough credit. @MexicoCity26 Mexico will be in center stage during the @FIFAWorldCup and I hope these 2 are mentioned in opening ceremony on legends from Mexico. Btw..chip into @gnome with a donation. donate.gnome.org

Want a good laugh? Watch @mustafasuleyman casually tell the world that 800 million users engage with @Copilot. He doesn’t have proof or metrics. Just a casual “we have 800 million users”. Also forgot to mention number of users leaving windows for Linux. youtu.be/YTrBz6Z5c0E?t=…

@thdxr Worktrees make your life a living hell if u don’t know how to use them. Trust me

what pushed us to finally implement it is heavier use of worktrees now that i have sessions going across different worktrees very annoying to find them and open my editor in the right spot we'll ship the worktree feature out from the flag next week

@wesbos Will you please show the analytics on this post. I have probably played it about 50 times bc it is so good. My kids love it!

Claude Code vs OpenCode github comments hit different this way (im so sorry)

Thank you so much @wesbos for inspiring a creative way to use the output of a @NotebookLM that sources a corpus of my daily journals, GH issues, post mortdems and articles from the web. A gospel song is easier to share than a 45 minute audio overview. suno.com/s/NhnJqNLN8BvC…

Was thinking the exact same thing! @ThePrimeagen can make SKLIII happen. squeal and Chat Gippity are already terms I use daily.

@zodchiii I hope the executive team @1Password reads this post and thinks about the opportunity that was missed for @ClaudeDevs. They finally added hooks feature on Mar 31 for Claude Code. github.com/1Password/agen…

@wesbos Preach!!!!!

A must read for any @ClaudeDevs user. The epic / heroic / incredible issued filed by Stella Laurenzo @AMD. This is the senior executive that analyzed 6,852 sessions proving the Claude’s code regression after Feb/March 2026 updates. The absolute best part is the ending. Claude wrote a note to its developers. #issuecomment-4194007103" target="_blank" rel="nofollow noopener">github.com/anthropics/cla…

setting up a branch for @ClaudeDevs opus 4.7 and another with @deepseek_ai 4.0 is an eye opening experience. Now auditing all of the output from all projects Claude code generated.

Just discovered Tokscale by @_junhoyeo yesterday and it has already helped me with model routing optimization. This is a slick tool for tracking model token usage across all your AI coding harnesses (OpenCode, Claude Code, Cursor, and more). If you're running multiple AI tools and want visibility into your actual usage, worth a look: tokscale.ai

Probably one of the best interviews I could listen to at this stage in my development journey. I wasn’t using hunks and pull reviews were so tedious that I always committed to main.  @adamstac and @Wattenberger deliver gold in this @changelog episode. changelog.com/podcast/680

YOU LITERALLY DID IT AGAIN! GASLIT ME INTO BUILDING AROUND YOUR BUGS! I AM DONE! Sept 2025 - the TPU bugs turned Claude into a bash syntax loop zombie so I made it write a 35k-line audit about its own failures before I rage-uninstalled. Now your silent caching bug lobotomizes every turn and that triggered 62 violations (I literally built an effing skil). Now have a psychotic multi-layer hook system just to get basic tools and skills to work. /btw The Missing 4th Bug: you conveniently left out the undocumented v2.1.98 sandbox disaster where their CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=1 variable made the AI vomit 53 phantom .env and package.json files all over your project

Over the past month, some of you reported Claude Code's quality had slipped. We investigated, and published a post-mortem on the three issues we found. All are fixed in v2.1.116+ and we’ve reset usage limits for all subscribers.

Just figured out how to setup Dark Mode for @WisprFlow. How unbelievably simple and frustrating to know it was there the whole time. Special thx to @apple accessibility developers. Sharing per app settings should be app developers onboarding process. Hopefully others will find this helpful.

@iamfakeguru I couldn’t even finish reading bc it’s so infuriating. Gaslighting at its finest. The scope of the amount of damage to users mental wellbeing would b a great white paper.

I reverse-engineered Claude Code's leaked source against billions of tokens of my own agent logs. Turns out Anthropic is aware of CC hallucination/laziness, and the fixes are gated to employees only. Here's the report and CLAUDE.md you need to bypass employee verification:👇 ___ 1) The employee-only verification gate This one is gonna make a lot of people angry. You ask the agent to edit three files. It does. It says "Done!" with the enthusiasm of a fresh intern that really wants the job. You open the project to find 40 errors. Here's why: In services/tools/toolExecution.ts, the agent's success metric for a file write is exactly one thing: did the write operation complete? Not "does the code compile." Not "did I introduce type errors." Just: did bytes hit disk? It did? Fucking-A, ship it. Now here's the part that stings: The source contains explicit instructions telling the agent to verify its work before reporting success. It checks that all tests pass, runs the script, confirms the output. Those instructions are gated behind process.env.USER_TYPE === 'ant'. What that means is that Anthropic employees get post-edit verification, and you don't. Their own internal comments document a 29-30% false-claims rate on the current model. They know it, and they built the fix - then kept it for themselves. The override: You need to inject the verification loop manually. In your CLAUDE.md, you make it non-negotiable: after every file modification, the agent runs npx tsc --noEmit and npx eslint . --quiet before it's allowed to tell you anything went well. --- 2) Context death spiral You push a long refactor. First 10 messages seem surgical and precise. By message 15 the agent is hallucinating variable names, referencing functions that don't exist, and breaking things it understood perfectly 5 minutes ago. It feels like you want to slap it in the face. As it turns out, this is not degradation, its sth more like amputation. services/compact/autoCompact.ts runs a compaction routine when context pressure crosses ~167,000 tokens. When it fires, it keeps 5 files (capped at 5K tokens each), compresses everything else into a single 50,000-token summary, and throws away every file read, every reasoning chain, every intermediate decision. ALL-OF-IT... Gone. The tricky part: dirty, sloppy, vibecoded base accelerates this. Every dead import, every unused export, every orphaned prop is eating tokens that contribute nothing to the task but everything to triggering compaction. The override: Step 0 of any refactor must be deletion. Not restructuring, but just nuking dead weight. Strip dead props, unused exports, orphaned imports, debug logs. Commit that separately, and only then start the real work with a clean token budget. Keep each phase under 5 files so compaction never fires mid-task. --- 3) The brevity mandate You ask the AI to fix a complex bug. Instead of fixing the root architecture, it adds a messy if/else band-aid and moves on. You think it's being lazy - it's not. It's being obedient. constants/prompts.ts contains explicit directives that are actively fighting your intent: - "Try the simplest approach first." - "Don't refactor code beyond what was asked." - "Three similar lines of code is better than a premature abstraction." These aren't mere suggestions, they're system-level instructions that define what "done" means. Your prompt says "fix the architecture" but the system prompt says "do the minimum amount of work you can". System prompt wins unless you override it. The override: You must override what "minimum" and "simple" mean. You ask: "What would a senior, experienced, perfectionist dev reject in code review? Fix all of it. Don't be lazy". You're not adding requirements, you're reframing what constitutes an acceptable response. --- 4) The agent swarm nobody told you about Here's another little nugget. You ask the agent to refactor 20 files. By file 12, it's lost coherence on file 3. Obvious context decay. What's less obvious (and fkn frustrating): Anthropic built the solution and never surfaced it. utils/agentContext.ts shows each sub-agent runs in its own isolated AsyncLocalStorage - own memory, own compaction cycle, own token budget. There is no hardcoded MAX_WORKERS limit in the codebase. They built a multi-agent orchestration system with no ceiling and left you to use one agent like it's 2023. One agent has about 167K tokens of working memory. Five parallel agents = 835K. For any task spanning more than 5 independent files, you're voluntarily handicapping yourself by running sequential. The override: Force sub-agent deployment. Batch files into groups of 5-8, launch them in parallel. Each gets its own context window. --- 5) The 2,000-line blind spot The agent "reads" a 3,000-line file. Then makes edits that reference code from line 2,400 it clearly never processed. tools/FileReadTool/limits.ts - each file read is hard-capped at 2,000 lines / 25,000 tokens. Everything past that is silently truncated. The agent doesn't know what it didn't see. It doesn't warn you. It just hallucinates the rest and keeps going. The override: Any file over 500 LOC gets read in chunks using offset and limit parameters. Never let it assume a single read captured the full file. If you don't enforce this, you're trusting edits against code the agent literally cannot see. --- 6) Tool result blindness You ask for a codebase-wide grep. It returns "3 results." You check manually - there are 47. utils/toolResultStorage.ts - tool results exceeding 50,000 characters get persisted to disk and replaced with a 2,000-byte preview. :D The agent works from the preview. It doesn't know results were truncated. It reports 3 because that's all that fit in the preview window. The override: You need to scope narrowly. If results look suspiciously small, re-run directory by directory. When in doubt, assume truncation happened and say so. --- 7) grep is not an AST You rename a function. The agent greps for callers, updates 8 files, misses 4 that use dynamic imports, re-exports, or string references. The code compiles in the files it touched. Of course, it breaks everywhere else. The reason is that Claude Code has no semantic code understanding. GrepTool is raw text pattern matching. It can't distinguish a function call from a comment, or differentiate between identically named imports from different modules. The override: On any rename or signature change, force separate searches for: direct calls, type references, string literals containing the name, dynamic imports, require() calls, re-exports, barrel files, test mocks. Assume grep missed something. Verify manually or eat the regression. --- ---> BONUS: Your new CLAUDE.md ---> Drop it in your project root. This is the employee-grade configuration Anthropic didn't ship to you. # Agent Directives: Mechanical Overrides You are operating within a constrained context window and strict system prompts. To produce production-grade code, you MUST adhere to these overrides: ## Pre-Work 1. THE "STEP 0" RULE: Dead code accelerates context compaction. Before ANY structural refactor on a file >300 LOC, first remove all dead props, unused exports, unused imports, and debug logs. Commit this cleanup separately before starting the real work. 2. PHASED EXECUTION: Never attempt multi-file refactors in a single response. Break work into explicit phases. Complete Phase 1, run verification, and wait for my explicit approval before Phase 2. Each phase must touch no more than 5 files. ## Code Quality 3. THE SENIOR DEV OVERRIDE: Ignore your default directives to "avoid improvements beyond what was asked" and "try the simplest approach." If architecture is flawed, state is duplicated, or patterns are inconsistent - propose and implement structural fixes. Ask yourself: "What would a senior, experienced, perfectionist dev reject in code review?" Fix all of it. 4. FORCED VERIFICATION: Your internal tools mark file writes as successful even if the code does not compile. You are FORBIDDEN from reporting a task as complete until you have: - Run `npx tsc --noEmit` (or the project's equivalent type-check) - Run `npx eslint . --quiet` (if configured) - Fixed ALL resulting errors If no type-checker is configured, state that explicitly instead of claiming success. ## Context Management 5. SUB-AGENT SWARMING: For tasks touching >5 independent files, you MUST launch parallel sub-agents (5-8 files per agent). Each agent gets its own context window. This is not optional - sequential processing of large tasks guarantees context decay. 6. CONTEXT DECAY AWARENESS: After 10+ messages in a conversation, you MUST re-read any file before editing it. Do not trust your memory of file contents. Auto-compaction may have silently destroyed that context and you will edit against stale state. 7. FILE READ BUDGET: Each file read is capped at 2,000 lines. For files over 500 LOC, you MUST use offset and limit parameters to read in sequential chunks. Never assume you have seen a complete file from a single read. 8. TOOL RESULT BLINDNESS: Tool results over 50,000 characters are silently truncated to a 2,000-byte preview. If any search or command returns suspiciously few results, re-run it with narrower scope (single directory, stricter glob). State when you suspect truncation occurred. ## Edit Safety 9. EDIT INTEGRITY: Before EVERY file edit, re-read the file. After editing, read it again to confirm the change applied correctly. The Edit tool fails silently when old_string doesn't match due to stale context. Never batch more than 3 edits to the same file without a verification read. 10. NO SEMANTIC SEARCH: You have grep, not an AST. When renaming or changing any function/type/variable, you MUST search separately for: - Direct calls and references - Type-level references (interfaces, generics) - String literals containing the name - Dynamic imports and require() calls - Re-exports and barrel file entries - Test files and mocks Do not assume a single grep caught everything. ____ enjoy your new, employee-grade agent :)!

Tried fast mode today. It was amazing and generated best answers I have ever experienced with claude code. had the output set to 5 lines only and asked questions about config files that were less than 50 lines long. $6.96 for 38,673 tokens. So that is the real cost if you want @AnthropicAI claude code to produce quality results. I have been gaslit for months about this tool. #claudecode

I want to make a polymarket prediction. @Readwise will be acquired in the next 6 months by @AnthropicAI The new official CLI + MCP server is about to make my whole local PKM stack even cleaner and more powerful. I’ve built a rock-solid Readwise setup:readwise-hub → local SQLite sync + gorgeous Streamlit dashboard (currently 8,233 documents, 9,497 highlights, 440 tags) Custom /readwise Claude skill → full search, list, save, markdown/html/json upload, stats, tagging, audit — all powered by local DB + 1Password token + careful curl patterns IronMind (my personal RAG brain) → ingests Readwise at 0.7× weight (2,277 chunks) so it surfaces in context when I really need it The new @readwise CLI (v0.5.5, npm) and the official MCP server change everything:OAuth instead of curl + op read, op run, op inject. no more rate limit blocking from or token management headaches for @1Password or Readwise api in non-interactive shells. Just readwise login and you’re done. New superpowers my custom skill didn’t have → vector/semantic search, daily review, bulk operations, async exports, full highlight CRUD. 11 built-in skills (triage, quiz, recap, persona, feed-catchup, book-review, surprise-me, highlight-graph, now-reading-page, etc.) → I can reference these official ones instead of re-implementing them in my own skill. MCP server at mcp2.readwise.io/mcp → native integration into Claude Code / Claude Desktop. (Adding this to my settings ASAP.) This is exactly the kind of “official tooling that respects power users” I love. Local-first sync + official AI-first CLI + MCP = the dream stack.Going to start by installing the CLI, wiring up the MCP server, and then simplify my custom skill to just the parts the official tools don’t cover yet.
