upd-project-description

upd-project-description is a command for coding agents from sgaunet/claude-plugins. It costs 22 tokens per session (1,170 once invoked), scanned B, original, MIT.

A command that reads a project’s README—a document describing the repository—and updates its online description and topic tags on GitHub, GitLab, or Forgejo.

In plain words
What is it for?
It is for extracting a short project description and relevant topics, then applying them to the hosted repository.
Why use it?
It saves the manual work of summarising a repository and editing its project metadata in the correct hosting service.

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 B, and why

upd-project-description scanned grade B with 2 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 4d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

`curl -X PATCH -H "Authorization: token <TOKEN>" -H "Content-Type: application/json" -d '{"description":"<description>"}' <api_base>/repos/<owner>/<repo>`

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Update Project Description Command

Update the description and topics of the current project. This command automatically detects whether the repository is hosted on GitHub, GitLab, or Forgejo and uses the appropriate CLI (or REST API for Forgejo) to update the project metadata (description and topics/tags).

Process

  1. Detect Repository Host: Use the detect-repo-host skill to identify the hosting service (GitHub, GitLab, or Forgejo) and extract owner/repo details.

  2. Analyze README: Use a Haiku agent to analyze the README.md file:

    • Extract concise project description (first 1-2 paragraphs, max 200 chars)
    • Identify relevant topics/tags from content (technologies, frameworks, keywords)
    • Return: {description: "...", topics: ["topic1", "topic2", ...]}
  3. Launch 2 parallel Haiku agents to update project metadata concurrently:

    Agent #1: Update Project Description

    • GitHub: gh repo edit --description "<description>"

    • GitLab: glab repo edit --description "<description>"

    • Forgejo: fgj has no repo edit subcommand — call the Forgejo REST API with curl, using the token from fgj auth token: curl -X PATCH -H "Authorization: token <TOKEN>" -H "Content-Type: application/json" -d '{"description":"<description>"}' <api_base>/repos/<owner>/<repo>

      <api_base> is the field returned by the detect-repo-host skill (e.g. https://git.sylvlab.fr/api/v1). Never hardcode a host.

    • Return: success/failure status

    Agent #2: Update Project Topics/Tags

    • GitHub: gh repo edit --add-topic "<topic>" (one per topic)
    • GitLab: glab repo edit --tag "<topic>" (one per topic)
    • Forgejo: fgj has no repo edit subcommand — call the Forgejo REST API with curl, using the token from fgj auth token (sets the full topic list in one call): curl -X PUT -H "Authorization: token <TOKEN>" -H "Content-Type: application/json" -d '{"topics":["<topic1>","<topic2>"]}' <api_base>/repos/<owner>/<repo>/topics
    • Return: success/failure status

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.
