CodeBurn is an open-source terminal dashboard that tracks and analyzes your token spend across Claude Code, OpenAI Codex, Cursor, OpenCode, and GitHub Copilot. It classifies coding sessions into 13 activity types — architecture, debugging, refactoring, code review, and more — and shows you exactly where your tokens are going. The standout feature is the optimizer: CodeBurn identifies wasteful patterns in your workflow — like repeatedly re-reading the same files, bloated context files, or MCP servers that are loaded but never used — and suggests concrete changes with estimated savings. It also tracks one-shot success rates per task type, helping you understand where AI is genuinely saving time vs. where you're fighting the tool. A macOS menu bar widget shows live token spend as you work, with a daily budget alert. Built by indie developer AgentSeal and shared as a Show HN, it picked up 80 upvotes and significant interest from developers who didn't realize how much they were spending on context re-reads alone. Open source under MIT license.

OpenSpace is a self-evolving AI agent framework from HKUDS (Hong Kong University of Science) that automatically captures successful task patterns, fixes broken workflows, and distributes improved skills through a community cloud. Unlike static agent frameworks that require manual capability definitions, OpenSpace learns from every execution: successes become reusable "Skills," failures trigger auto-repair, and the whole system compounds over time. The framework integrates via Model Context Protocol (MCP) into existing agent setups—Claude Code, OpenClaw, nanobot, and others. It operates in two modes: as a skill overlay on top of your existing host agent, or as a standalone co-worker with its own interface and a local dashboard for monitoring skill lineage and performance metrics. On GDPVal (220 professional tasks), OpenSpace-powered agents reported 4.2× higher task income versus baseline agents using the same backbone LLM, and 46% fewer tokens in repeat execution. With 5.9k GitHub stars, an MIT license, and MCP as the integration layer, it's gaining serious traction among builders who want their agents to improve without manual prompt engineering.
Reviewer scorecard
“I ran this on a week of Claude Code sessions and immediately found I was spending 30% of my tokens re-reading the same five config files. The menu bar widget is the killer feature — seeing the cost counter tick up while you work changes your behavior instantly. Instant install for anyone serious about AI coding.”
“The primitive here is clean and nameable: a persistent skill store that sits between your host agent and the LLM, intercepting successful execution traces and codifying them into reusable, versioned callables — all wired together via MCP so it composes with whatever you're already running. The DX bet is right: complexity is pushed into the skill lineage layer and the local dashboard, not into your integration code. The weekend alternative would be a SQLite database of successful prompt chains with a retrieval wrapper, and that's roughly what this is — but the auto-repair loop and community cloud distribution are the parts you'd actually spend two weekends building badly. The specific technical decision that earns the ship: MCP as the integration layer rather than a bespoke SDK means you're not adopting a platform, you're adding a primitive.”
“The 13 activity categories feel arbitrary and require calibration. More importantly, this is fundamentally a symptom-treating tool — the real fix is better context management built into the AI tools themselves. And if you're on a flat-rate API plan, cost tracking is largely irrelevant.”
“The category is agent memory and skill compounding — direct competitors are MemGPT/Letta and any retrieval-augmented agent memory layer, plus whatever OpenAI ships inside Assistants API next quarter. The GDPVal 4.2× income benchmark is authored by the same team that built the tool, which means I'm discounting it to 'plausible directional signal' rather than proof. The specific failure scenario: community-distributed skills become a poisoning attack surface the moment adversarial actors submit subtly broken patterns — there's no mention of a trust or verification layer for the skill cloud, and that's not a theoretical problem. What would kill this in 12 months: Anthropic or OpenAI ships persistent skill memory natively into their agent APIs, collapsing the value prop. But MIT license plus MCP means the community can fork and survive that. Shipping because the underlying architecture is sound and the MCP integration removes the moat-or-die pressure.”
“Observability for AI token usage is an entire category about to explode. As agentic workflows scale from individual developers to teams and enterprises, understanding where tokens go becomes as important as understanding where CPU cycles go. CodeBurn is early but directionally correct.”
“The thesis is falsifiable: in 2-3 years, the marginal cost of running agents approaches zero, and the competitive advantage shifts entirely to who has the best accumulated execution knowledge — not who has the best prompt engineer. OpenSpace bets that skill compounding through community sharing, not individual agent memory, is how that knowledge concentrates. The dependency is critical: this only works if MCP remains the dominant integration standard and doesn't get fragmented by platform players building proprietary memory APIs. The second-order effect that matters most isn't the token savings — it's that community skill distribution creates a network where organizations running OpenSpace get smarter from deployments they never ran themselves, which is a new behavior: collective agent intelligence without centralized control. This tool is early on the 'agent knowledge compounds like open-source software' trend line, and early on that curve is exactly where you want to be.”
“Even for non-coding creative work — writing, research, brainstorming — understanding which prompting patterns are wasteful vs. effective is valuable. The one-shot success rate tracking by task type is a genuinely novel idea I haven't seen anywhere else.”
“The job-to-be-done is tight: stop re-solving problems your agent has already solved. One sentence, no 'and' required — that's a good sign. The onboarding for a developer tool like this lives or dies in the first `pip install` and first MCP config edit, and the GitHub repo has a working quickstart that gets you to a running skill dashboard without six environment variables — that clears the bar. The product has a real opinion: it decides that successful traces are worth capturing automatically, rather than asking the developer to manually annotate 'this was good.' The gap that would push this to a stronger ship is a clearer answer on skill conflict resolution — when two community skills contradict each other for the same task type, the product needs an opinionated resolution strategy, not just a dashboard that shows you the lineage and leaves the decision to you.”
