Codex CLI leads the revised ranking; Factory Droid rises on documented BYOK, and six draft claims needed correction

Asked (summary)

Do you agree with the draft ranking of CLI agent harnesses for T3 Code + fx on an Ubuntu VPS (2 vCPU, 3.8 GB RAM, ~2.3 GB free) using Nebius Token Factory with DeepSeek V4.1 Flash? If not, adjust and rerank the recommendations.

Partial disagreement, and a rerank. Eleven harnesses are rescored on stack fit for the stated weights — these are judgment scores, not measured benchmarks — backed by 180 product-evidence rows, 145 repository-fact rows, 15 focused fact checks, and 4 Nebius protocol findings, all scanned 2026-11-02. Mainplane and Vercel eve are out-of-category, and dsh-superagent remains an add-on, not a harness. Live project facts can change.

Revised ranking — stack-fit score out of 100

Codex CLI takes first: T3-native, Rust, Apache-2.0, sandboxed, with a documented custom OpenAI base URL path — github.com
Factory Droid moves substantially up: official docs confirm BYOK custom models with a generic-chat-completion provider type, local API keys, and headless droid exec — docs.factory.ai
Harness choice moves tokens per solved task up to ~40× while paired pass rates move only 0–8 points — the harness, not the model, sets the token bill — menfem.com
A second 2026 study measured 5–30× cost-per-success gaps between two harnesses at comparable success rates, driven by a 12–15× larger fixed prefix and 2–7× more turns — arxiv.org
Nebius Token Factory lists DeepSeek V4.1 Flash at $0.30 in / $1.20 out per million tokens with a ~1M context, on an OpenAI-compatible API, public id deepseek-ai/DeepSeek-V4.1-Flash — optinest.de

Keep fx, add Codex CLI and omp

Codex CLI for T3-native work against Nebius; omp as the extensible second harness. Do not add both pi and omp — omp is a pi fork and their roles overlap (github.com).

Conditional

dsh only for its plugin path, then Kilo

Add dsh only if the DeepSeek-specific plugin/superagent path is a real use case (github.com). Kilo is the next optional open generalist (github.com).

Skip for this stack

Factory Droid capable but closed; Claude/Cursor/Amp/Devin poor fits

Droid now documents BYOK and headless exec yet adds little beside fx/omp/Codex (docs.factory.ai). Claude Code speaks Anthropic Messages, not generic OpenAI (docs.anthropic.com).

What changed from the draft

Capability matrix and evidence

#HarnessScoreLicenseStarsBYOKCustom base URLACPMCPSubagentsEvidence rowsSource

Method: stack-fit judgment scores (0–100) on the user's stated weights for 11 CLI agent harnesses, not benchmark measurements. Evidence: 180 product-capability rows deduplicated to canonical products, 145 repository-fact rows (official repositories preferred, forks excluded), 15 fact checks of official Factory and T3 material and 2026 research, and 4 Nebius/model findings — scanned 2026-11-02. Capability cells are the majority reading across each product's evidence rows; dashes mean no evidence found. Mainplane, Vercel eve, and dsh-superagent were cut as out-of-category. Live project facts can change.
