bump-skill-version

bump-skill-version is a skill for Claude Code from blockscout/agent-skills. It costs 79 tokens per session (1,184 once invoked), scanned A, original, MIT.

A maintenance guide for changing a coding skill's version number everywhere it is recorded in a repository.

In plain words
What is it for?
Use it after updating a skill, providing its name and the new version so the related version entries can be updated.
Why use it?
It prevents the skill's version from becoming inconsistent between its own files, the marketplace listing, and any skill-specific references.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bump-skill-version scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bump Skill Version

Update a skill's version string in every file that references it. This skill works for any skill in the repo: it first applies a shared bump procedure (frontmatter version + marketplace plugin entry), then consults a per-skill reference file for any extra locations specific to that skill.

Usage

Pass <skill-name> <new-version> as $ARGUMENTS (e.g., blockscout-analysis 0.5.0). If either is missing, ask the user before proceeding.

<skill-name> must match a top-level skill directory in the repo root (e.g., blockscout-analysis/, web3-dev/). Verify the directory and its SKILL.md exist before making any edit.

Shared procedure (applies to every skill)

These three edits are required for every skill bump.

1. <skill-name>/SKILL.md — frontmatter metadata

The YAML frontmatter contains a single-line JSON metadata field with a "version" key:

metadata: {"author":"blockscout.com","version":"<OLD>","github":...}

Replace "version":"<OLD>" with "version":"<NEW>". Use exact strings — do not use regex replacements.

2. .claude-plugin/marketplace.json — plugin entry version

The marketplace manifest has a plugins array; each entry has its own "name" and "version" fields. The bare string "version": "<OLD>" may appear in more than one plugin entry when versions happen to coincide, so the old_string passed to Edit must include the "name" line of the target plugin to disambiguate. Match a block like this:

"name": "<skill-name>",
      "description": "...",
      "source": "./<skill-name>/",
      "strict": false,
      "version": "<OLD>",

Replace only the "version": "<OLD>" line within that block with "version": "<NEW>". Leave the top-level marketplace metadata.version untouched — it tracks the marketplace as a whole, not the individual skill.

3. .agents/plugins/<skill-name>/.codex-plugin/plugin.json — codex plugin descriptor

Each skill that ships as a Codex plugin has its own descriptor at .agents/plugins/<skill-name>/.codex-plugin/plugin.json. The descriptor is dedicated to one skill, so the version field is unambiguous — but include the "name" line in the old_string anyway as a sanity check that the right file is being edited:

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
