# Sigil Launch Set

`sigil/launch-set` · Collection · v1.0.0

The first seven Sigil skills, each with its own proof suite, for the APIs and safety rules coding agents most often get wrong in late 2026.

Seven skills that carry current, precise knowledge a coding agent otherwise gets wrong: GitHub Actions hardening, zero-downtime PostgreSQL migrations, MCP servers on the v2 TypeScript SDK, Vercel AI SDK 7 tools and structured output, Express 5, Zod 4 and accessible React widgets. Every member ships with a three-task suite whose hidden verifier fails on the starting repo and passes on the reference solution, so its effect can be measured rather than assumed. Installing the bundle installs each member in its own native format; each member keeps its own digest and evidence.

## Verdict

- level: **submitted** — In the catalog, not yet checked for this digest.
- uplift: **untested** — No runs exist for this digest.
- digest: `sha256:c9adede55aaa0112a123cfe9dd3232e904557564ebdb6426574f9622f1ac5898`

## Uplift runs

None for this digest. Untested is not the same as useless: nobody has measured it yet.

## Security

No checks recorded for this digest.

## Limitations

- Results for the bundle measure all seven skills installed together. A member can help on its own suite and still be diluted or crowded out when every skill is loaded; read each member's own result too.
- Every member is pinned to the versions it was checked against (November 2026). Projects on older majors (AI SDK 5-6, MCP SDK v1, Express 4, Zod 3, PostgreSQL before 12) get migration notes, not full coverage.
- The suites are small (three tasks each), so early results are likely to be inconclusive until more runs and tasks exist.
