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.

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 | $0.00028 | $0.00371 |
| Opus 5 | $0.00014 | $0.00186 |
| Sonnet 5 | $0.00006 | $0.00074 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
ast-introspection 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.
What it actually says
AST Introspection
When to Use
- Need a structure-aware view (functions, methods, types, receivers) or a safe, mechanical refactor proposal that relies on code shape rather than string matches.
What This Skill Does
- Enumerates package-level declarations (funcs, methods, types, const/var) with
path:linecitations. - Extracts function/method signatures, receivers, and doc comments.
- Lists imports and flags suspicious patterns (duplicates, likely unused groups).
- Proposes minimal, mechanically-safe refactors (rename, extract, signature change) with verification steps.
Rules
- Prefer read-only inspection (glob, grep, targeted read) before any edit.
- Always include
path:linecitations for code claims. - Never perform large automated rewrites without an explicit preview, tests, and verification commands.
Commands
- Enumerate packages:
go list ./... - Quick exported view:
go doc <pkg>
Output
- Inventory: compact list of declarations with
path:line. - Findings: 2-8 concise bullets (impact + confidence).
- Proposal: minimal patch plan (files/hunks) + exact verification commands.
Examples
- "List all exported methods on type
Authwith file locations." - "Propose a safe rename for method X and verify callers."

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.

ast-introspection is a skill published in the GitHub repository pilinux/gorest (504 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 371 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
