Reset is a free, open-source Mac menu bar app that shows where you stand on your Claude Code usage window and turns red when you are about to run out, so you stop waking up to a half-gone window.
A user paired Grok Bot with OpenCode running the free Big Pickle model, so Grok Bot hands longer coding jobs to OpenCode and spends fewer credits.
DHI Orbit is one local board for Claude Code, Codex, Cursor, Gemini CLI and Antigravity that shows what needs you, what is working, your usage limits and a reply box.
MuscleMemory remembers how a task was done only when tests passed, and trusts it after two more passing sessions. Claude Code reusing skills Codex learned used 43.5% fewer input tokens.
The author wrote a Codex skill that swaps models by effort to save usage, then found Codex running a subagent on a local Qwen model through Ollama.
Built Agent Orchestra so a main model plans and checks while cheaper models do read and search work.
Built Lookout, a local-first macOS notch app that shows which coding agent needs you, token spend, plan limits and live dev servers for Claude Code, Codex and Cursor.
Built an open-source model router that ensembles coding agents to reach Astra-level performance cheaper than one frontier model.
Paste a token address and a council of agents led by Grok inspects it in real time before he buys.
Frugal Tokens reads your coding agent sessions and shows overall usage, estimated working time, overlapping sessions and where spend comes from across models and cache misses.
Built Frugon, a local MIT tool that finds which LLM calls a cheaper model could have handled.
Built Lowfat, a pluggable CLI filter the author says saved 91.8% of their LLM tokens.
After checking 73 compactions and finding 26 summaries that dropped a server, deployment or port the agent was using, a developer built compact-receipts to log what each compaction dropped.
The author set a Grok Bot to check a specific account's posts every 15 minutes for usage-limit reset announcements so they can use remaining quota first.
In one hour with Codex the author built a desktop app that projects your music, your Claude Code activity or your token bills as 3D particles.
Answer me with HTML is an agent skill: ask a hard question and get one readable offline HTML page with diagrams instead of terminal text. The author says the model writes about 1/8 of the tokens it would need to hand-write the HTML.
Janas streams mixture-of-experts weights from SSD so a 48 GB Qwen3-Next-80B model runs on a 32 GB laptop. The author measured 24-37 tokens per second writing versus 2.8 for llama.cpp on the same machine.
Built smart-compactor so Claude Code compacts context when a task is done instead of when the window is full.
Two BI veterans built Graphene so a coding agent can do analyst work: a token-efficient semantic layer with SQL queries, plus Markdown dashboards it can publish, connected to warehouses or local DuckDB.
Reported that Spotify’s Portal cut Claude Code token usage by about 90% in their workflow.
Built Graft, Claude Code hooks that cut grep tokens by about 42%.
Llmspeed simulates tokens per second and time to first token for models like Qwen, Gemma and GPT-OSS on GPUs and Macs, based on verified benchmarks, so you can feel the speed before you buy.
Pi subagents Lite gives the Pi.dev coding harness subagents with minimal token overhead and detailed control over what enters the agent's system prompt.
Sygal converts PDF, Word, Excel, images, web pages and even YouTube links into clean Markdown and JSON locally, so documents drop into a prompt or knowledge base with far fewer tokens.
