We killed RAG and sandboxes. Here's what we built instead.
Our documentation assistant had a problem. RAG pipelines only sent the model page fragments, making responses feel half-baked. The fix was obvious: give the agent full doc access. Quality jumped, but startup hit 46 seconds and costs ballooned to $70K+/year.
The insight: the agent doesn't need a real filesystem. It just needs to think it's in one.
We built ChromaFs, a virtual filesystem that translates standard UNIX commands into queries against our Chroma database. Every doc page becomes a file, every section a directory. The agent explores documentation the way a developer explores a codebase.
The results: startup dropped from 46s to ~100ms, marginal compute cost hit $0 per conversation, and output quality matched the full sandbox, with access control built in.
ChromaFs now powers 30,000+ daily conversations for hundreds of thousands of users. No containers, no cold starts, no invoice surprises.
Mintlify powers docs for 20,000+ companies, reaching 100M+ people a year. We just raised a $45M Series B led by a16z and Salesforce Ventures to keep building the knowledge layer for the agent era.
S&P 500 is continuing to push higher into the afternoon session, and the structure is becoming increasingly clear as price action moves decisively beyond the 7350 level. What was previously viewed as a potential Wave 5 completion zone has now been exceeded, shifting the focus toward higher Fibonacci extension targets and reinforcing the possibility that the market is not simply finishing a cycle—but expanding into a more powerful phase.
As of 12:12 PM PT, the S&P has already cleared the 7350 region, which was based on a standard Elliott Wave relationship where Wave 5 equals Wave 1. Typically, that level acts as a natural area for exhaustion or at least temporary consolidation. However, the fact that price has moved cleanly beyond it without hesitation suggests that momentum remains strong and that the market is not exhibiting typical late-stage behavior.
This leaves two primary targets in focus.
The first is the 7500 level, derived from the relationship where 0.618 × Wave 1 added to Wave 3 defines an extended fifth-wave projection.
0.618
This 7500 zone is now the next logical upside objective under a traditional Wave 5 framework. It represents a continuation of the current trend but still assumes that the market is operating within the final leg of a completed five-wave structure. If price begins to slow, consolidate, or show signs of divergence near this level, it would support the idea that the current move is nearing completion.
However, the more aggressive—and increasingly plausible—scenario is that the S&P is not in a Wave 5 at all, but rather in a higher-degree Wave 3 expansion.
If that interpretation is correct, then the current breakout is not the end of the move—it’s the acceleration phase.
Under this framework, the key Fibonacci projection shifts to the 1.618 extension, which targets approximately 8320.
1.618
The 8320 level represents a full-scale Wave 3 expansion, where price moves beyond standard expectations and enters a phase driven by strong institutional participation, macro tailwinds, and broad market alignment. In this type of environment, pullbacks tend to be shallow, and resistance levels are cleared with increasing ease.
What’s important here is the behavior of the market as it approaches these levels. A controlled move into 7500 followed by hesitation would suggest a Wave 5 completion scenario. But continued acceleration, strong breadth, and leadership from high-beta sectors would favor the Wave 3 interpretation and open the door to significantly higher prices.
The broader context also supports the more bullish case. With the NASDAQ already breaking out to new highs and semiconductor and AI-related names leading the charge, the market is showing characteristics more consistent with expansion than exhaustion. Leadership remains strong, and there is little evidence of the kind of divergence typically seen at major tops.
In summary, the S&P has now moved beyond its initial Wave 5 target at 7350, leaving 7500 as the next key level under a standard framework, and 8320 as the upside objective if the market is indeed entering a larger Wave 3 expansion. The coming sessions will be critical in determining which of these scenarios ultimately plays out—but for now, momentum remains firmly to the upside.
