At a glance

- Needing a structure-aware list of functions, methods, or types in a Go package
- SKILL.md covers When to Use, What This Skill Does, Rules and Commands, plus 4 more sections
- Calls go
- Proposing a safe rename or signature change with its callers checked
What it does
This skill reads Go source through its syntax tree rather than string matching, listing package-level functions, methods, types, and const or var declarations together with a path and line number. It extracts signatures, receivers, and doc comments, and flags suspicious import patterns such as duplicates or likely-unused groups.
Its output favors looking before touching anything: a compact inventory of declarations, a short list of findings with impact and confidence, and a minimal patch plan naming the files and hunks involved along with exact verification commands. It avoids large automated rewrites without an explicit preview and passing tests first.
When your agent uses it
- Needing a structure-aware list of functions, methods, or types in a Go package
- Proposing a safe rename or signature change with its callers checked
- Reviewing imports for duplicates or unused groups before a refactor
Example prompts
- “List all exported methods on the Auth type with their file locations.”
- “Propose a safe rename for the Validate method and check its callers.”
- “Show me the signatures of every function in the payments package.”
What it can do on your machine
Read from SKILL.md and the folder at commit 38aab64. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
go
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Go AST Code Introspection loads about 414 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 168 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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."
