What it does
Release is an agent skill from fl-sean03/OpenSDL. Build and validate OpenSDL release candidates by synchronizing versions and producing every workspace distribution locally. Use when cutting or rehearsing a coordinated project release. It does not publish, sign, or tag.
Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `run.sh`).
It sits in Agent Workflows. The repository describes itself as: A modular Python foundation for reproducible computational and autonomous laboratories. Alpha; the reference profile is simulator-only. The licence is Apache-2.0.
When your agent uses it
- Rehearsing a coordinated project release
Example prompts
- “/release”
Requirements
- A Bash shell
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Start from a clean worktree and an absent or empty dist/. Review changes since the previous
- Run .agents/skills/release/run.sh VERSION.
- Review synchronized workspace versions, installed CLI and API version reporting, citation
- Do not recreate the import-evidence files at the repository root. They describe the imported
- Inspect every wheel and source archive under dist/.
- Record the exact validation evidence and unresolved release work.
What it can do on your machine
Read from SKILL.md and the folder at commit 43f4988. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Release loads about 580 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 300 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- release
- description
- Build and validate OpenSDL release candidates by synchronizing versions and producing every workspace distribution locally. Use when cutting or rehearsing a coordinated project release. It does not publish, sign, or tag.
Build a release candidate
This procedure ends at built artifacts in dist/. It does not upload to a package index, sign an
artifact, generate an SBOM, create a Git tag, or create a GitHub Release, and neither does
.github/workflows/release.yml, which runs the same gate on a clean runner and uploads the
distributions as an expiring Actions artifact. Nothing has ever been published or tagged. What
publishing would additionally require, and what it costs irreversibly, is written down in
releasing and publishing; do not improvise it here.
Inputs
- target version
- reviewed release scope and notes
Procedure
- Start from a clean worktree and an absent or empty
dist/. Review changes since the previous release — there is not yet a first one, so the scope is the whole history until there is. - Run
.agents/skills/release/run.sh VERSION. - Review synchronized workspace versions, installed CLI and API version reporting, citation metadata, generated dependency floors, public API changes, schemas, and migration guidance.
- Do not recreate the import-evidence files at the repository root. They describe the imported
snapshot and live at the import commit;
docs/development/import-provenance.mdrecords where and why. - Inspect every wheel and source archive under
dist/. - Record the exact validation evidence and unresolved release work.
Completion
All workspace distributions build from the reviewed revision, and the test, lint, type, schema, boundary, example, and conformance checks pass. The artifacts are local and unpublished.
Stop conditions
Stop on a dirty worktree, a nonempty dist/, a failing check, an unexpected public API change, or
an unexpected artifact.
Stop and hand back to the repository owner before any step that leaves the machine: registering a project name, configuring a trusted publisher, uploading a distribution, or pushing a tag. Claiming a name on a package index cannot be undone, and an uploaded version can never be re-uploaded.

When should I use Release?
Release fits situations like: rehearsing a coordinated project release.
How do I install Release in Claude Code?
Run `npx skills add fl-sean03/OpenSDL --skill release -a claude-code`. Or copy the skill folder (.agents/skills/release in fl-sean03/OpenSDL) into .claude/skills/release in your project. Claude Code loads it when a task matches its description.
How do I install Release in Codex?
Run `npx skills add fl-sean03/OpenSDL --skill release -a codex`. Or copy the skill folder (.agents/skills/release in fl-sean03/OpenSDL) into .agents/skills/release in your project. Codex loads it when a task matches its description.
Can I use Release in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add fl-sean03/OpenSDL --skill release -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/release, .gemini/skills/release, .github/skills/release and .opencode/skills/release in your project.
What does Release need to run?
Going by SKILL.md and its folder, Release needs a shell for the scripts in its folder. Our summary lists: A Bash shell.
Does Release access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Release safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Release use?
Release is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Release use?
About 580 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Release?
