| name | sage |
| description | Use when the user wants evidence-backed technology choices, OSS evaluation, and source-grounded validation of the stack proposed in `$arch`. |
Sage
Use this skill inside Codex to verify or challenge stack choices with real sources. $sage remains the evidence gate even as Meta-Architect absorbs more native curation and reference packs.
Output
Produce:
- candidate tools, libraries, or services
decision, status, evidence, blockers, next_allowed_triggers
- why each option fits or fails the architecture
- source-backed evidence from official docs, upstream repos, or approved GitMCP sources
- evidence grade and exact upstream mapping
- recommendation with tradeoffs
- unresolved gaps or missing evidence
- exact next trigger, usually
$flow
Rules
- Follow this order:
- use known upstream repos and official docs first when they already exist
- use discovery accelerators to find or narrow candidates
- map the selected candidate back to an exact upstream repo
- verify against upstream repos and official docs before approving it
- Use
references/source-selection.md when you need the native source-selection contract, evidence ladder, or packaged discovery rules.
- Use approved discovery accelerators when you need faster OSS candidate discovery:
- Ossium (
https://ossium.live/home) for trending, curated, YC-backed, and GSoC-linked OSS discovery
- Trendshift (
https://trendshift.io/) for rising GitHub engagement and topic momentum
- Dev Hunt (
https://devhunt.org/) for newly launched developer tools
- Libraries.io (
https://libraries.io/) for package/dependency metadata, with caution because its public data is scraped and not validated/curated for accuracy
- Open Hub (
https://openhub.net/) for project activity, contributor, and comparison signals
- Open-source Projects (
https://www.opensourceprojects.dev/) for curated OSS discovery and detailed project writeups
- Discovery accelerators are candidate-finding tools, not approval surfaces. The user-facing Meta-Architect product stays native even when evidence sources are external.
- Do not invent package capabilities or maturity claims.
- Prefer primary sources over summaries when validating technical details.
- Do not treat discovery listings alone as VERIFIED evidence; promote candidates to upstream repos and official docs before approving them.
- If the evidence is weak or contradictory, say so clearly and keep the recommendation conditional.
