Publish the libcrafter crafter crate to crates.io only after the local release gate, cargo publish dry-run, package summary, ask-tool confirmation, and crates.io/docs.rs verification.

What it does

Agent Cargo Publish is an agent skill from pellegre/libcrafter. Publish the libcrafter crafter crate to crates.io only after the local release gate, cargo publish dry-run, package summary, ask-tool confirmation, and crates.io/docs.rs verification.

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with Git. The repository describes itself as: A Rust library for constructing, sending, capturing, and decoding network packets. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/agent-cargo-publish”

Requirements

  • A credential in CARGO_REGISTRY_TOKEN

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Verify the release context
  2. Run the local release gate
  3. Run the publish dry run
  4. Check whether the exact version already exists on crates.io. Prefer
  5. Summarize what will change before asking
  6. Ask for approval with an ask-capable tool immediately before publishing. Use
  7. Publish
  8. Verify and report

What it can do on your machine

Read from SKILL.md and the folder at commit f9ef000. 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

    Shell commands in SKILL.md call:

    • cargo
    • git
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • crates.io
    • docs.rs

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • CARGO_REGISTRY_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent Cargo Publish loads about 651 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~651

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.

Agent Cargo Publish

Use this skill when asked to publish the crafter crate from this repository to crates.io.

Publishing is irreversible. Do not run the real cargo publish command unless all gates pass and the user explicitly approves through an ask-capable tool. Plain-text confirmation is not enough.

Required Order

  1. Verify the release context:
    • git status --short must be empty.
    • Record git rev-parse --abbrev-ref HEAD and git rev-parse HEAD.
    • Read the crate name and version from Cargo metadata and require crafter as the package.
    • Target crates.io only.
  2. Run the local release gate:
sh
.agents/scripts/check-crafter-release --static
  1. Run the publish dry run:
sh
cargo publish -p crafter --dry-run --locked
  1. Check whether the exact version already exists on crates.io. Prefer:
sh
curl -fsSL "https://crates.io/api/v1/crates/crafter/<version>"

Stop if the query succeeds. 5. Summarize what will change before asking:

  • crate and version
  • registry
  • git branch and commit
  • package contents summary from the release gate or cargo package --list
  • crates.io metadata/readme update from the packaged Cargo metadata
  • docs.rs build expected from the published package
  1. Ask for approval with an ask-capable tool immediately before publishing. Use request_user_input when that tool is available. The question must name the exact crate, version, registry, and commit. Provide a non-publish option and a publish-now option. Proceed only if the user chooses the publish-now option.
  2. Publish:
sh
cargo publish -p crafter --locked
  1. Verify and report:
    • crates.io package page: https://crates.io/crates/crafter/<version>
    • docs.rs page: https://docs.rs/crafter/<version>/crafter/

If docs.rs is still building, report it as pending with the expected URL. Do not try to force docs.rs.

Hard Stops

Stop before real publishing if:

  • the working tree is dirty
  • the release gate or dry run fails
  • the crate version is already published
  • the ask-capable tool is unavailable
  • the user does not explicitly choose the publish-now option
  • credentials are missing or cargo reports authentication failure

Never use --allow-dirty or --no-verify for the real publish. Never print CARGO_REGISTRY_TOKEN or any credential value.
