Graphenium vs Skills

Graphenium 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.

Graphenium

Graphenium indexes a repository into a persistent, queryable knowledge graph and exposes it over MCP, so assistants like Claude or Cursor can answer dependency and call-chain questions in roughly 20 ms without reading source files at each turn. The graph survives across sessions, which means structural knowledge does not have to be rebuilt every time you open a new conversation. The gain is sharpest on large or multi-module repos where grep-and-trace navigation collapses under its own weight. The constraint is real: this is a static graph service, not an agent — it answers questions but does not plan or act, so any reasoning on top of the data remains the assistant's job.

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.

Pros	Persistent graph survives session boundaries, so an assistant navigating a large repo does not waste token budget re-establishing structural context at the start of every conversation. MCP-native interface means Claude, Cursor, and other compatible assistants query the graph without a custom integration layer — which avoids the glue-code maintenance burden that plagues one-off tool wrappers. Approximately 20 ms query latency (per project documentation) on call-chain and dependency lookups, so structural questions do not introduce noticeable lag into assistant response cycles. MIT-licensed and self-hosted, so the repository's source code never leaves your infrastructure — critical for teams whose codebases cannot touch external APIs under their security policy. .grapheniumignore support lets teams exclude generated or vendored directories, keeping the graph lean and preventing noise from third-party code polluting dependency queries.	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	Re-indexing is a manual step: the graph does not update automatically when files change, so after a significant refactor or merge, dependency answers will be stale until someone runs the indexer again — teams doing rapid iteration find themselves managing index freshness as a separate chore. The project shows 1 commit and 8 stars at the time of scraping, which means community-validated workarounds, issue resolutions, and third-party integrations are sparse; teams hitting an edge case will be debugging against thin documentation and a small issue backlog rather than a searchable community history. There is no hosted or managed option — setup, updates, and uptime are entirely the team's responsibility; teams without the infrastructure bandwidth to run a self-hosted Rust service will switch to a managed code-intelligence alternative rather than absorb the operational overhead.	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.

Bottom line

Only Graphenium exposes a public API. Choose based on which difference matters most for your workflow.
