Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00075 | $0.04480 |
| Opus 5 | $0.00037 | $0.02240 |
| Sonnet 5 | $0.00015 | $0.00896 |
| Haiku 4.5 | $0.00007 | $0.00448 |
Grade B, and why
jig-doctor scanned grade B with 1 finding 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 9d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
jig Doctor
Use this repository skill to diagnose the installed jig state across every supported target and scope. This skill never modifies files or settings.
Distribution Model
Each CLI is installed on its own, but diagnosis inventories all of them before judging any one instance.
- Claude Code plugin is host-managed and may be enabled at project, local, user, or managed scope. Its skills are namespaced as
/jig:<skill>and its host version is not compared with file payload tags. - Claude Code standalone is a compatibility installation under
.claude/skillsor~/.claude/skills. A current installation has a.jig-installationledger plus per-skill.jig-provenance; a verified legacy copy may have no ledger yet. - Codex and Antigravity have no plugin system. Their project and global rules files carry independent managed blocks and version stamps; skill roots differ by target and scope.
Installation Inventory
Use this exact contract, shared with jig-update. Inventory all rows before deciding that jig is absent or healthy.
| Target | Scope | Installation evidence |
|---|---|---|
| Claude Code | project | jig@jig enabled in .claude/settings.json |
| Claude Code | local | jig@jig enabled in .claude/settings.local.json |
| Claude Code | user | jig@jig enabled in ~/.claude/settings.json |
| Claude Code | managed | jig@jig reported at managed scope by claude plugin list --json |
| Claude Code standalone | project | valid .jig-installation or verified legacy jig skill set under ./.claude/skills |
| Claude Code standalone | user | valid .jig-installation or verified legacy jig skill set under ~/.claude/skills |
| Codex | project | jig managed block in ./AGENTS.md |
| Codex | global | jig managed block in ~/.codex/AGENTS.md |
| Antigravity | project | jig managed block in ./GEMINI.md |
| Antigravity | global | jig managed block in ~/.gemini/GEMINI.md |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

jig-doctor is a skill published in the GitHub repository 0x0w1/jig (5 stars, last pushed 9d ago), licensed MIT. It adds 75 tokens to every session and 4,480 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

trace
Dispatch trace subagent to investigate unknown issues — reproduces, traces, and reports root cause for fix handoff.
codex-agent
Use when you want a second-opinion review via Codex CLI, cross-verification after another agent implements changes, debugging help, or alternative implementation proposals. Requires Codex CLI to be installed and authenticated.
