add-harness From the maker
Agenta-AI/agentaSkill
Playbook for adding a new coding-agent harness to Agenta (Codex, Hermes, Gemini, OpenCode, ...). Use when starting, planning, or reviewing a new-harness project. Covers the readiness audit of prior art, the spike-first milestone plan, the full integration-surface checklist, the per-harness variance axes to probe, and the process/communication contract with Mahmoud. Living document: every harness project appends its lessons to resources/LESSONS.md.
Why this score
This repo hosts 10 skills, so its 4,845 stars are split between them (about 485 each) for scoring.
Popularity score: 67/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Oct 21, 2026 at commit 7d337aec1ac3, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
