I am using DeepSeek extensively to develop apps, three in the last month, with my own CLI coding agent [1] developed by DeepSeek itself line by line. I haven't spent $1 yet in well over 10 million tokens.

If I considered myself a 10X programmer, now I am 100X. Love DeepSeek.

Have you compared it against other coding agents? What is your general workflow with DeepSeek; do you write a spec and then have it implement and test? Very interesting to hear. Becuase your harness is adapted to DeepSeek, you probably prompt and it very differently; since its adapted to the model this may explain why it works well for you. Wiring up an existing harness that is not tested on DeepSeek may not yield optimal results.
