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

generate-feature-doc 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 5d 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.

Origin

This is a copy

92% identical to generate-feature-doc — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Name

jira:generate-feature-doc

Synopsis

/jira:generate-feature-doc <feature-key>

Description

The jira:generate-feature-doc command generates comprehensive feature documentation by recursively analyzing a Jira feature ticket and all its related issues, sub-tasks, and linked GitHub pull requests.

This command is particularly useful for:

  • Creating complete feature documentation after implementation
  • Understanding the full scope and implementation details of a feature
  • Generating onboarding materials for new team members
  • Creating technical design documents from actual implementation
  • Documenting complex features with multiple related issues and PRs

The command performs deep analysis of:

  • The main feature issue and all related Jira tickets (recursively)
  • All linked GitHub PRs, commits, and code changes
  • Design decisions captured in PR discussions and code reviews
  • Implementation details from actual code changes

Implementation

This command orchestrates two skills in sequence to generate comprehensive feature documentation:

  1. Extract GitHub PRs (via jira:extract-prs skill)

    • Discovers all descendant issues recursively using childIssuesOf() JQL
    • Extracts PR URLs from Jira Remote Links (primary) and text content (backup)
    • Fetches PR metadata from GitHub (state, title)
    • Returns structured JSON with deduplicated PRs
  2. Generate Documentation (via jira-doc-generator skill)

    • Receives PR data from step 1
    • Analyzes MERGED PRs only (fetches metadata, diff, comments)
    • Synthesizes feature documentation with the following sections:
      • Overview
      • Background and Goals
      • Architecture and Design
      • Usage Guide
      • Related Resources (External Links only)
    • Skip sections: Implementation Details, Testing
    • Outputs to .work/jira/feature-doc/<feature-key>/feature-doc.md

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.
