file-search-on: Skill for Claude Code

.claude/skills/reddit-golang-post/SKILL.md

reddit-golang-post is a skill for Claude Code from richardwooding/file-search-on. It costs 149 tokens per session (1,178 once invoked), scanned A, original, MIT.

A writing helper for preparing self-posts for the r/golang Reddit community, which is focused on the Go programming language. It creates Markdown with a title and optional flair, then copies the post body to the macOS clipboard.

In plain words
What is it for?
Use it to draft Show & Tell posts or discussion and help posts about Go, including headings, code blocks, lists, and links.
Why use it?
It separates the Reddit title and flair from the body so each can be pasted into the correct part of Reddit’s editor. It also follows different structures for project announcements and discussions or help requests.

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

reddit-golang-post 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/copy.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

r/golang Post

r/golang's post composer accepts markdown directly — headings, fenced code blocks, lists, and [text](url) links all render. No format conversion is needed; the script just splits the YAML frontmatter (which carries the title and optional flair) from the body and pipes the body to pbcopy. The author's job is the writing — the etiquette of r/golang is what makes or breaks the post.

Quick start

  1. Gather from the user: topic, key technical points, repo / reference URLs, post type (Show & Tell vs Discussion / Help).
  2. Pick a template — templates/show-and-tell.md.tmpl for project announcements, templates/discussion.md.tmpl for questions / opinion-seeking.
  3. Draft to /tmp/reddit-golang-post.md. Frontmatter must include title:; optionally flair:.
  4. Run bash .claude/skills/reddit-golang-post/scripts/copy.sh /tmp/reddit-golang-post.md — body markdown lands on the clipboard; title and flair print to stderr.
  5. Tell the user to paste the title into Reddit's title field, select the flair from the dropdown, switch the editor to Markdown mode, and paste the body.

Post shape

Mode Word target Use for
Show & Tell 200–600 words "I built X" project announcements
Discussion / Help 100–400 words Specific questions, design opinions

Reddit caps body at 40,000 characters but engagement drops sharply past ~1500 words. Posts under 50 words read as low-effort. Always include a one-line TL;DR at the top or bottom for posts longer than ~600 words.

Frontmatter format

---
title: "Show & Tell: file-search-on — search files by metadata via CEL"
flair: Show & Tell
---
  • title: is required. Keep under 300 chars (Reddit's hard cap); under ~120 chars reads better in the feed.
  • flair: is optional. Reddit's flairs change occasionally — common ones on r/golang are Show & Tell, Help, Discussion, Newbie Question, Code Review, Generics.
  • Quotes around the title are recommended (handles colons and special chars cleanly).

What ships with it

4 files 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.

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.
