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 | $0.01614 |
| Opus 5.5 | $0.00011 | $0.00646 |
| Sonnet 5.5 | $0.00006 | $0.00323 |
| Haiku 4.5 | $0.00003 | $0.00161 |
Grade A, and why
google-chat-formatting 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google Chat Formatting
Expert knowledge for converting Markdown and plain text to Google Chat's limited formatting syntax. Google Chat supports a subset of formatting that differs from standard Markdown.
When to Use This Skill
| Use this skill when... | Use ticket-drafting-guidelines instead when... |
|---|---|
| Converting Markdown to Google Chat's single-asterisk bold and bullet syntax | Drafting a GitHub issue, PR description, or technical ticket |
| Formatting status updates, meeting notes, or release notes for posting in Google Chat | Writing a structured What/Why/How bug report or feature request |
| Stripping headers and tables for a chat-channel announcement | Producing prose intended for a GitHub or docs surface (keep standard Markdown) |
Core Expertise
Format Conversion
- Transform Markdown headers to bold text
- Convert list markers to bullet symbols
- Adapt bold/emphasis syntax to Google Chat format
- Preserve code blocks and inline code
- Ensure mobile-friendly spacing and readability
Google Chat Limitations
- No native header support (use bold instead)
- Limited text formatting (bold, italic, strikethrough, code)
- Bullet symbols (U+2022) instead of hyphen lists
- No nested formatting (bold inside italic, etc.)
- No tables, images, or advanced Markdown features
Conversion Rules
Headers to Bold Text
Google Chat has no header support. Convert all headers to bold text:
# Header → *Header*
## Subheader → *Subheader*
### Section → *Section*
Pattern: Remove all # symbols and wrap text in single asterisks.
Text Formatting
Google Chat uses single asterisks for bold (not double):
**bold** → *bold*
__bold__ → *bold*
*italic* → _italic_
_italic_ → _italic_
~~strikethrough~~ → ~strikethrough~
Key differences:
- Bold: Single asterisks
*text*(not**text**) - Italic: Single underscores
_text_(not*text*) - Strikethrough: Single tildes
~text~ - No nested formatting support
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.

google-chat-formatting is a skill published in the GitHub repository laurigates/claude-plugins (59 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 1,614 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
Other skills, from other repositories
handoff
Writes a short handoff note when a session ends mid-task so the next session or person can continue without re-discovery, and resumes from one. Use when asked to hand off, save progress, or continue from a handoff note.
prerequisites
Read-only report of external tools the enabled plugin fleet declares, and which of them are missing. Use when a hook says a formatter or CLI is missing, or when asking whether this machine has what the enabled plugins need. Never installs.
context-engineering
How to budget and structure what a coding agent sees. Use when asked to trim, split or write AGENTS.md, CLAUDE.md, rules files or skill descriptions (for example 'CLAUDE.md is too long'), when an agent ignores instructions, forgets rules or drifts in long sessions, and when planning compaction or progress notes.
telegram
Send notifications, interactive questions, or multiple-choice polls to the user via Telegram. Use when the user asks to be notified ("ping me", "notify me on Telegram", "ask me when..."), when a long-running task finishes and the user is likely away, when an irreversible action needs out-of-band confirmation, or when…
skillbook
Pokemon Pokedex-style skill dashboard. Tracks usage, levels, rarity, achievements. Use when: 'show skills', 'skill stats', 'open dashboard'. Not for skill auditing.
reflect
Self-assessment of AI session quality. Scores 5 dimensions from session data and harness memory. Not an agent performance review — it's human self-reflection on how well they used AI assistance. Use when the user says "reflect", "how did I do", "session review", or at the end of a long session.
