A command for checking recent software problems across error monitoring, support requests, and app-store reviews.

Use it for an on-demand bug check for contracts in their four-week monitoring period, including creating new JIRA tickets when connected tools support it.

It groups related reports and checks whether they already have tracking tickets, reducing duplicate investigation and ticket creation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.00525
Opus 5	$0.00009	$0.00262
Sonnet 5	$0.00004	$0.00105
Haiku 4.5	$0.00002	$0.00052

Measured 5d ago against content hash 1965ad5f01c3, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-05, from the pricing page.

Security

Grade A, and why

epub2skill 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.

What it actually says

Agent CLI Usage

Use this skill to run epub2skill correctly and consistently.

Goal

Convert one or more EPUB files into an agent-usable skill directory with SKILL.md, bookindex.md, and resources/.

Command Template

epub2skill "<epub-or-glob>" \
  --skill <skill-name> \
  --targets <target-list> \
  --description "<skill-description>"

Required Rules

Always set --skill using kebab-case.
Always verify input path or glob matches .epub files.
Prefer --targets opencode-project unless user asks otherwise.
Add --force only when user explicitly wants overwrite behavior.

Target Reference

claude-project: <project>/.claude/skills/<skill-name>
claude-global: ~/.claude/skills/<skill-name>
opencode-project: <project>/.opencode/skills/<skill-name>
opencode-global: ~/.config/opencode/skills/<skill-name>
qwen-project: <project>/.qwen/skills/<skill-name>
qwen-global: ~/.qwen/skills/<skill-name>

Recommended Workflow

Confirm EPUB source path or glob.
Choose a clear --skill name.
Choose target(s) based on user scope (project vs global).
Run conversion command.
Verify generated files:
- SKILL.md
- bookindex.md
- resources/**/*.md

Example Commands

epub2skill "./books/meditations.epub" \
  --skill stoicism-guide \
  --targets opencode-project \
  --description "Answer based on Meditations by Marcus Aurelius"

epub2skill "./books/*.epub" \
  --skill philosophy-library \
  --targets opencode-project,claude-project \
  --merge \
  --description "Ground responses in converted philosophy books"

Output Validation

If no EPUB matches, stop and report the unmatched path/glob.
If target already exists and --force is not set, stop and report conflict.
After success, report:
- number of EPUB files converted
- target directories written
- whether merge mode was used

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.
