Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Gossamer LLM Reference

Generated from `SKILL.md` and `docs_src/api/stdlib.json`. This is deliberately scoped: only catalog entries with a standalone executable example and explicit verified status may appear as API recommendations.

## Language primer

# Gossamer - Skill Card

Drop this file into a model's context to teach it idiomatic Gossamer. For
anything not covered here, ask the toolchain (section 2) instead of guessing.

## 1. What Gossamer is

A fast-compiling language with deterministic memory management (reference
counting, cycle collection, `arena { }` regions - no borrow checker, no
lifetimes, no GC pauses). Syntax is Rust-flavoured; the runtime is Go-shaped
(goroutines, channels). Files end in `.gos`, the toolchain is `gos`, and a
project carries a `project.toml`. Programs run on the bytecode VM and JIT
(`gos run`) and as native binaries (`gos build`), with the same output on
every tier; `gos feature-status` says which surface is settled.

## 2. Lean on the toolchain

- `gos mcp` (e.g. `claude mcp add gossamer -- gos mcp`) exposes `check`,
  `execute`, `build`, `test`, `fmt`, `doc`, `explain`, `lint`,
…

How to install

The exact contents, by fingerprint
mdr add gossamer-lang/gossamer/llms-full.txt@sha256:84b078c97fe3f640

The line at the top of this page pins the label git:20261016.0fb4f89, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
