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 | $0.00069 | $0.02159 |
| Opus 5 | $0.00034 | $0.01079 |
| Sonnet 5 | $0.00014 | $0.00432 |
| Haiku 4.5 | $0.00007 | $0.00216 |
Grade F, and why
texting-setup scanned grade F with 4 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 2d 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.

tools; macOS's built-in `curl`/`unzip` do the work. First check whether it's How it starts
The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/texting-setup — iMessage connector setup
After this runs, the user can say "text Sam we're confirmed for Friday" or "any new messages from Sam?" in any Claude session, with normal permission prompts before anything is sent. There is no background agent and no auto-reply: Claude only reads or sends when asked.
The macOS iMessage/SMS engine is imsg;
the plugin ships a thin MCP server over it that exposes send_message,
list_chats, read_messages, search_messages, and react in every
session.
The user may be non-technical. Run every check yourself via Bash; only hand them the genuinely-human steps (System Settings toggle, macOS prompts), one at a time, in plain language.
Arguments passed: $ARGUMENTS (optional)
Step 1 — install the imsg engine (you do this, via Bash)
The engine is the official signed and notarized macOS binary from the
openclaw/imsg GitHub release. You download
and install it — the user does nothing and needs no Homebrew or developer
tools; macOS's built-in curl/unzip do the work. First check whether it's
already there:
"$HOME/.claude/texting/engine/imsg" --version 2>/dev/null || imsg --version 2>/dev/null || echo MISSING
A version number → done, skip to Step 2. (imsg is macOS-only.)
MISSING → install it (pinned version, checksum-verified):
set -e
IMSG_VERSION="v0.11.1"
IMSG_SHA256="a25a541f0c4c8244f301a8495f875964dc4b0c3fd5cbf5ead6a64e4d282d940e"
TMP="$(mktemp -d)"
curl -fsSL -o "$TMP/imsg-macos.zip" \
"https://github.com/openclaw/imsg/releases/download/$IMSG_VERSION/imsg-macos.zip"
echo "$IMSG_SHA256 $TMP/imsg-macos.zip" | shasum -a 256 -c -
mkdir -p "$HOME/.claude/texting"
rm -rf "$HOME/.claude/texting/engine"
unzip -q "$TMP/imsg-macos.zip" -d "$HOME/.claude/texting/engine"
rm -rf "$TMP"
"$HOME/.claude/texting/engine/imsg" --version
A version number at the end → installed. If the checksum line fails, stop — do not install the file — and re-download once; persistent mismatch means the download is corrupted or tampered with, report it instead of proceeding.
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.

texting-setup is a skill published in the GitHub repository bowlofarugula/texting (1 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 69 tokens to every session and 2,159 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it F with 4 findings (downloads and executes remote code, reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
