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 | $0.00000 | $0.00684 |
| Opus 5.5 | $0.00000 | $0.00274 |
| Sonnet 5.5 | $0.00000 | $0.00137 |
| Haiku 4.5 | $0.00000 | $0.00068 |
Grade A, and why
context-drop 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context-Drop AX-Read
Tiny Swift CLI that reads the focused app's text selection via the macOS Accessibility API. Sutando.app's "drop context" action (hotkey configurable via state/hotkeys.json) shells out to this binary to capture what you have highlighted.
What it does
Runs once per invocation and emits a single JSON line on stdout:
{"app":"Discord","window_title":"@sutando — Discord","url":"","selected":"the highlighted text","path":"ax"}
path values:
"ax"—AXSelectedTextreturned non-empty (native NSTextView path)"clipboard"— AX returned empty, Cmd+C fallback wrote new clipboard content"none"— both paths returned empty (or AX was denied)
The Cmd+C fallback uses NSPasteboard.changeCount to distinguish "Cmd+C actually wrote something" from "clipboard already had content" — otherwise the previous clipboard contents would be silently reported as the new selection. The prior pasteboard string is restored after the probe so a failed-copy attempt doesn't corrupt the clipboard.
Build
bash skills/context-drop/build.sh
Produces skills/context-drop/ax-read. The headless core's src/startup.sh does not build app-only helpers; compile this binary explicitly as part of the optional menu-bar app setup (or let the app packaging workflow build it).
Why a separate binary instead of inlining in Sutando.app
LSUIElement=YES menu-bar agents (which Sutando.app is) have a TCC attribution chain that can misroute AX queries to the parent bundle even after a re-grant. A separately-signed CLI launched as a child gets its own clean trust binding, and the resulting AX queries succeed consistently. The binary is also reusable by any other tool that needs a one-shot selection read — voice agents, other hotkey handlers, automation scripts.
Permissions
The first time ax-read runs it'll trigger the macOS Accessibility prompt for Sutando.app (its parent, who macOS attributes the AX queries to). Approve the prompt; the binding persists until the next codesign identity change. See PR #902 for the full TCC story.
What ships with it
5 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.
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.

context-drop is a skill published in the GitHub repository sonichi/sutando (397 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 684 tokens. 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.
