open-supply-hub: Skill for Claude Code

.agent/skills/plan-ticket/SKILL.md

plan-ticket is a skill for Claude Code, Codex from opensupplyhub/open-supply-hub. It costs 52 tokens per session (1,078 once invoked), scanned A, original, MIT.

A skill for reading a Jira ticket and writing an implementation plan to a Markdown file. Markdown is a plain-text format commonly used for documentation.

In plain words
What is it for?
Use it to plan an OS Hub Jira ticket by reviewing its details, inspecting related code, researching available documentation, and recording the proposed work. It does not write code, create branches, or commit changes.
Why use it?
It gives the team a researched scope and approach before coding begins, while keeping the work limited to planning.

This is opensupplyhub/open-supply-hub's own configuration. It tells Claude Code and Codex how to work on open-supply-hub itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-supply-hub configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

plan-ticket 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 10d 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.

Planning an OS Hub Ticket

The job: read the ticket, do real research, write a quality plan to a markdown file. No code. No branches. No commits. Just the plan.

Step 1 — Confirm the ticket

If the user did not name a ticket, ask:

Which ticket should I plan? Reply with the OSDEV key (e.g., OSDEV-2316).

Step 2 — Read the ticket

Fetch from Jira via the Atlassian MCP. The OS Hub Atlassian site is opensupplyhub.atlassian.net — use this to identify the workspace when calling the MCP.

Extract: summary, description, acceptance criteria, labels.

Step 3 — Name the complexity

State the complexity level and the reason in one sentence. The user decides what to do with that information.

  • RED — touches dedupe pipeline, ECS/Terraform, or core DB schema
  • YELLOW — new Django model, full-stack change, or touches search
  • GREEN — text changes, new field in an existing API, or new UI component

Step 4 — Research

Pull from every source available. The goal is a quality plan, not just any plan.

  • The codebase — find similar features, read them as templates. If the OS Hub Codebase Expert sub-agent is available, delegate this; otherwise read directly.
  • Confluence — search the OS Hub Development Home space for the feature, related specs, or prior decisions.
  • GitHubgit log --oneline -20 and gh pr list --state merged --limit 15 --json title,number,files for recent similar PRs.
  • AGENTS.md and the .agent/skills/ resources — apply existing conventions, patterns, known gotchas.
  • Session context and memory — anything shared earlier or auto-loaded.
  • External connectors (optional) — ask once: "Do you have Granola, Google Drive, Monday, HubSpot, or other MCP connectors with context that might help on this ticket?" If yes, pull from them. If no or unsure, skip and continue.

If you can't find something, say so. Don't guess.

Step 5 — Write the plan to a markdown file

Save to ~/.claude/plans/OSDEV-####.md (create the directory if needed).

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.
