AI-factory vs Skills

AI-factory and Skills are both cli coding agents tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

AI-factory

The repo structures the AI coding workflow around specs, roles, skills, agents, and hooks — all defined in config, not scattered across prompt files. An adversarial review bench pits agents against each other before code reaches a human, and deterministic gates block merges when quality checks fail. This fits teams already running Claude Code or similar agents who want repeatable process rather than one-off prompt magic. The toolkit is early-stage — five commits, zero open issues — which means the primitives are present but the community-tested edge cases are not. Teams pushing beyond the documented patterns write their own skills and roles, which is supported by the model but undocumented territory.

Skills

Orbit is a CLI harness that wraps any JSON-speaking coding agent — Claude, Codex, Cursor, or your own — in a bounded loop: one task selected from a dependency-ordered backlog, executed by the agent, then checked against tests, lint, and type validation before the orbit closes. If the agent cannot prove the work, the run does not advance. Every orbit writes structured JSON artifacts and a human-readable progress log, so you are reviewing evidence rather than re-reading diffs and guessing. The harness runs entirely locally, requires no API key for the replay demo, and is MIT licensed. Where it breaks: teams whose validation needs go beyond tests and lint — custom scoring rubrics, multi-step human approval workflows, or large parallel backlogs — will find the intentionally small surface area a ceiling rather than a feature.

Platforms	Claude Code, codeoid	Cross-platform (Python 3.6+)
Pros	Config-driven role and skill model, so the agent's capabilities and constraints are version-controlled alongside the codebase rather than living in someone's prompt history that disappears when they leave. Adversarial review bench routes AI-generated code through challenging agents before it reaches a human reviewer, so you catch architectural violations and regressions before they land in the PR queue. Deterministic quality gates enforced at merge time, so AI-generated code that passes vibe checks but fails structural constraints gets blocked at the pipeline rather than discovered in production. Fully open-source and self-hosted with no paid tier, so there is no usage ceiling or vendor dependency to negotiate around when you scale the number of agents or projects running through the pipeline. Spec-driven pipeline from issue to PR, so the agent operates against an explicit contract rather than inferring intent from a ticket — which reduces the class of hallucinated features that looked reasonable to the model but weren't in scope.	Validation gates block an orbit from closing unless tests, lint, and type checks pass, so you stop merging agent output that ran without error but failed to do what the task required. Four structured artifacts per run — result, evaluation, review recommendation, and a progress log — give you an auditable evidence trail, so post-mortem debugging is reading JSON rather than reconstructing what the agent did from git history. Agent-neutral CLI contract means you can run Claude and Codex against the same task and backlog, comparing scored artifacts directly instead of running separate experiments with incomparable outputs. Dependency-ordered backlog selection keeps each orbit focused on one task at a time, so the agent cannot silently absorb scope from adjacent work and produce diffs that are hard to attribute. MIT licensed with a no-API-key replay demo, so you can evaluate the full validation loop against a real artifact chain without committing credentials or incurring cost.
Cons	The repository has five commits and an empty issue tracker at the time of curation. There is no community corpus of solved problems to draw from, which means the first team to hit a non-obvious failure in their pipeline is also the team writing the fix — with no prior art to reference. The toolkit is explicitly coupled to Claude Code in its documentation. Teams running a different coding agent adapt the AGENTS.md and workspace config themselves; the effort is unbounded until they have tested every skill and hook their pipeline touches. Complex SDLC branching — multiple parallel feature tracks, conditional merge strategies, cross-repo orchestration — is not covered in the documented patterns. Teams that need this add a custom skill layer, at which point they are maintaining the toolkit and an extension system simultaneously. This is the condition under which teams building non-trivial multi-repo pipelines move to a more established CI/CD orchestration layer and treat ai-factory's gate model as an idea to port rather than a system to adopt.	Validation is limited to tests, lint, and type checks as described on the vendor page — teams whose definition of 'done' includes semantic correctness, security scanning, or domain-specific rules have to build that checking outside the harness and wire it in manually, adding a second system to maintain. The harness executes one orbit at a time; teams running large backlogs where tasks are independent and could parallelize will hit a throughput ceiling and move to a more capable orchestration layer or build parallelism themselves. There is no built-in multi-step human approval workflow beyond the accept/iterate/stop recommendation in `review.json` — teams that need a formal sign-off gate before code advances to staging will need to script that around the harness or switch to a tool that treats human review as a first-class execution step.
