dotclaude is a lightweight workflow pattern (not a framework) for running multiple AI coding agents in parallel without incurring extra API costs. It exploits the CLI non-interactive resume mode of Claude, Codex, and Gemini — spinning them up in tmux panes and letting them iterate on different aspects of a codebase simultaneously. The project is explicitly positioned as a "practical workflow, not a polished framework." The core insight is that you can achieve multi-agent collaboration by composing existing CLI tools (tmux, agent CLIs, shell scripts) rather than building or buying dedicated orchestration infrastructure. Context is shared via files; agents communicate by reading and writing to the same working directory. It's rough around the edges and requires comfort with the command line, but the approach is genuinely clever: no new dependencies, no framework lock-in, and no extra API tokens beyond what you'd spend running each agent individually. The HN thread attracted developers interested in the minimal-overhead angle, particularly those already running multiple coding agents manually.

Perplexity Sonar Pro 2 API
Search-grounded LLM API with live web citations for developers

Sonar Pro 2 is Perplexity's upgraded search-grounded language model available via API, designed for developers building research-heavy or real-time-information applications. It delivers live web grounding with improved citation accuracy and reduced latency compared to its predecessor. Developers can call it like any LLM API but get responses anchored to current web content with source attribution baked in.
Reviewer scorecard
“This is the kind of DIY cleverness that eventually becomes best practice. Using tmux + CLI resume mode to approximate multi-agent coordination is a zero-dependency solution that works with the tools most developers already have. Rough but real.”
“The primitive here is clean: drop-in LLM API that returns grounded responses with citations as first-class output fields, not hallucinated footnotes. The DX bet is that developers should not have to build their own retrieval pipeline just to answer a question about something that happened last week — and that bet is correct. The first 10 minutes are solid: standard REST API, familiar messages array, citations come back in the response object alongside content. The honest weekend alternative is Bing Search API plus GPT-4o plus a prompt template, which is a real 200-line project that breaks in subtle ways around freshness and deduplication. Sonar Pro 2 earns the ship specifically because citation accuracy as a versioned, improving API primitive is something worth paying for rather than maintaining yourself.”
“File-based agent communication breaks down fast when agents make conflicting edits. There's no conflict resolution, no proper state management, and no error recovery. This is a proof-of-concept that will frustrate you on any non-trivial project.”
“Direct competitor is Bing Grounding in the Azure OpenAI stack and Google's Grounding with Search in Gemini API — both from platform players with vastly deeper distribution. The scenario where Sonar Pro 2 breaks is anything requiring structured extraction from grounded results at scale: the citations are helpful but the model still hallucinates about which citation supports which claim when the context gets noisy. What kills this in 12 months is not a competitor — it's OpenAI or Google making web grounding a zero-marginal-cost feature bundled into their base API tiers, which both have explicitly telegraphed. The ship here is conditional: Sonar Pro 2 is genuinely better at citation freshness than either platform alternative right now, and 'right now' is what the pricing is selling. For teams that need live-web grounding today without building infra, it earns the call — but build your abstraction layer thin.”
“The fact that developers are jury-rigging multi-agent coordination with tmux and shell scripts shows how strong the demand is for parallel AI workflows. The gap between what people want and what polished frameworks offer is still wide enough for creative workarounds like this to get traction.”
“The thesis Sonar Pro 2 is betting on: within 2-3 years, most LLM applications need continuous web grounding by default, and the teams building them will pay for a specialized grounding-first API rather than assembling it from commoditized parts — specifically because citation provenance becomes a legal and compliance requirement in regulated verticals. The dependency that has to hold is that citation accuracy remains meaningfully differentiated from what platform players bundle in, which requires Perplexity to keep investing in index quality and freshness rather than riding the same underlying models. The second-order effect that's underappreciated: if Sonar Pro 2 wins in the enterprise API tier, it shifts the definition of LLM output quality from 'fluent text' to 'verifiable claims' — that's a genuine reframing of how developers and product teams evaluate model outputs. The trend this is riding is AI moving from generation to verification, and Sonar is early enough that the positioning is credible. The infrastructure future state where this wins is when citation APIs become a standard column in every AI vendor comparison, and Perplexity set the terms.”
“This requires serious CLI comfort and debugging patience. For creative workflows that involve coding, the productivity cost of managing tmux sessions and debugging agent conflicts outweighs the benefits for most people.”
“The buyer is a developer team at a company that needs real-time information in a product — news apps, research tools, financial dashboards — pulling from a discretionary engineering tools budget. The problem is the moat: this is a retrieval-augmented generation API in a market where the retrieval layer is being commoditized by every major model provider simultaneously. When OpenAI bundles web search into GPT-4o API calls at no additional cost, Perplexity's margin story collapses unless they can demonstrate that their index freshness and citation quality justify a persistent premium. The specific structural issue is that Perplexity's defensibility lives in the consumer product's brand, not in the API — developers don't have brand loyalty, they have cost models. Until the citation quality delta over platform alternatives is quantified in a reproducible benchmark not authored by Perplexity, this is a skip for any team building a funded product that will still be running in two years.”
