specrew-version

An informational skill that reports the installed Specrew version and whether its slash commands match the project’s configured baseline version.

In plain words
What is it for?
Use it when checking the Specrew installation, slash-command compatibility, or a compatibility issue before or after an update. It can target a specified project path or the current project.
Why use it?
It helps identify version mismatches before troubleshooting command compatibility. It reports version information only and does not approve any project lifecycle change.

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

specrew-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 2d 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.

specrew-version

Type: Informational Skill Schema: v1 Status: Active Namespace: /specrew Canonical command: /specrew-version

Purpose

Show the installed Specrew version and slash-command compatibility state. Reports both the installed/runtime version and the project baseline version from .specrew/config.yml.

When to Use

  • When a contributor wants to know which version of Specrew is installed.
  • When checking whether the slash-command surface is compatible with the current baseline.
  • When diagnosing compatibility issues before or after specrew update.
  • Invoke this skill when the user says: "What version of Specrew is installed?", "Show Specrew version", "Is the slash-command surface compatible?", "Check Specrew version".

Boundary Safety

This skill provides version and compatibility information only. It does not authorize or imply approval to advance any lifecycle boundary.

Invocation

/specrew-version [--project-path <path>]

Backed by: specrew version / scripts/specrew-version.ps1

Inputs

Input Type Required Description
--project-path string No Target Specrew project path (defaults to current directory)

Outputs

  • Installed Specrew version (from module or Specrew.psd1)
  • Project baseline version (from .specrew/config.yml)
  • Slash-command compatibility state:
    • compatible — the installed version can service the project baseline recorded in .specrew/config.yml
    • incompatible — the installed version is older than the project baseline; upgrade guidance is shown
    • unknown — the installed version cannot be determined
  • Remediation guidance when compatibility is not met:
    • For outdated installed version: Update-Module Specrew or equivalent
    • For a matching development tree: set SPECREW_MODULE_PATH
    • For outdated project baseline: specrew update

Argument Whitelist

Only --project-path is accepted in v1. Unknown arguments are rejected with explicit help guidance.

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.
