ultra-jira-mcp: Skill for Claude Code

.claude/skills/jira-mcp-dev/SKILL.md

ultra-jira-mcp-dev is a skill for Claude Code from criblio/ultra-jira-mcp. It costs 76 tokens per session (1,432 once invoked), scanned A, original, MIT.

Contributor instructions for changing ultra-jira-mcp, a tool that connects coding agents to Jira, a project-management system for issues and tasks. It explains where to add Jira operations, how the code is organized, and how to test changes.

In plain words
What is it for?
Adding Jira REST or Agile operations, changing the server or command-line interface, understanding the dispatcher and response handling, and running tests or benchmarks.
Why use it?
It removes the need to rediscover which files and code layers handle a Jira request. It also gives repo contributors guidance for tests and benchmarks.

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

ultra-jira-mcp-dev 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ultra-jira-mcp contributor skill

You are working inside the ultra-jira-mcp repo (npm package name; the binaries it ships are still jira-mcp and jira-cli). This skill teaches the architecture and the toolkit boundary so you don't have to re-derive them on every task.

For a longer prose version, see CLAUDE.md.

The three layers

Every Jira call flows through the same three layers — internalize this before touching anything in src/:

  1. Manifest — src/core/operations.ts declares the endpoint (path, HTTP verb, param roles, optional trim key, optional isAgile: true).
  2. Dispatcher — src/core/manifest.ts (invokeOperation) reads the manifest entry, builds the HTTP call via JiraClient, sandboxes the full response, and applies the trim.
  3. Surface — either a consolidated classic tool (src/tools/v2/<category>.ts — one per category, each a oneOf dispatcher) or the single code-api tool (src/codeapi/tool.ts), which hands the agent a path to jira-cli and a unix socket.

The CLI (src/cli/index.ts) is a fourth surface that reads the same manifest — same dispatcher, same trims, no MCP server required.

Adding a new Jira operation

The common case. Steps, in order:

  1. Add a manifest entry in src/core/operations.ts. Keep entries grouped by category section comment. Naming is category.verb where verb is logical, not HTTP (so issue.transition, not issue.post).
  2. Add a trim if the response is bulky. Trims live in src/core/trim.ts; register the key in trim-registry.ts. The trim's job is to produce the small object the agent sees on stdout — everything else gets written to disk and referenced via ref: /path.
  3. Route the action from the relevant src/tools/v2/<category>.ts dispatcher so classic-mode users get it. Code-api mode picks it up automatically from the manifest.
  4. Tests: add a fixture-based test under tests/core/ for the trim and a smoke test under tests/tools/ for the dispatcher path. Live Jira calls are not allowed in unit tests.
  5. If the operation changes the tool-list size meaningfully (new category, large new schema), run npm run benchmark and note the new numbers in docs/BENCHMARK.md.

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.
