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

ghi-list 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 12d 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.

GHI List - Formatted GitHub Issues Table

Display GitHub issues in a clean ASCII box-drawing table format.

Usage

/ghi-list [options]

Options (passed to gh issue list)

  • --state open|closed|all - Filter by state (default: open)
  • --assignee <user> - Filter by assignee
  • --label <label> - Filter by label (can repeat)
  • --limit <n> - Max items to fetch (default: 30)
  • --author <user> - Filter by author
  • --milestone <name> - Filter by milestone

Execution Steps

  1. Run gh issue list with any provided options plus --json number,assignees,labels,title,state
  2. Format output as an ASCII table using box-drawing characters
  3. Truncate titles to fit reasonable terminal width (~45 chars)
  4. Show first assignee only, or "-" if none
  5. Show first 2-3 labels abbreviated, or "-" if none

Output Format

Use this exact table style with box-drawing characters:

┌───────┬────────────┬─────────────────┬───────────────────────────────────────────────┬────────┐
│ Issue │ Assignee   │ Labels          │ Title                                         │ State  │
├───────┼────────────┼─────────────────┼───────────────────────────────────────────────┼────────┤
│   372 │ max        │ enhancement     │ Create /pr-list and /ghi-list skills          │ OPEN   │
│   371 │ -          │ bug, priority   │ Fix null pointer in auth module               │ OPEN   │
│   370 │ joe        │ -               │ Update documentation for new API              │ CLOSED │
└───────┴────────────┴─────────────────┴───────────────────────────────────────────────┴────────┘

Table Requirements

  • Use Unicode box-drawing: ┌ ┐ └ ┘ ├ ┤ ┬ ┴ ┼ │ ─
  • Right-align issue numbers
  • Left-align text columns
  • Pad columns consistently
  • For assignees: show login of first assignee, "-" if none
  • For labels: show comma-separated names (truncate if >17 chars)
  • Show count summary below table: "N issues (M open, K closed)"

Example Commands

# Default - open issues
gh issue list --json number,assignees,labels,title,state

# With filters
gh issue list --state all --label bug --json number,assignees,labels,title,state

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.
