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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 53 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00036 | $0.03323 |
| Opus 5 | $0.00018 | $0.01662 |
| Sonnet 5 | $0.00007 | $0.00665 |
| Haiku 4.5 | $0.00004 | $0.00332 |
Grade A, and why
terminal-ux scanned grade A with 1 finding 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.

`curl`'s progress meter goes to stderr despite not being an error, because it is messaging about the run rather than the payload. How it starts
The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Terminal UX
How a terminal program should behave. Two different things live here and their rules diverge:
- CLI: a command that runs, prints, and exits. No persistent screen. State is communicated by printing what changed.
- TUI: a full-screen interactive app that owns the terminal until it quits. A grid that redraws.
Every rule below says which it applies to. A CLI rule does not automatically hold for a TUI, and the sources differ: clig.dev, the 12-factor CLI writeup, GNU, and POSIX are CLI-first, while the TUI material comes from ratatui, Bubble Tea, Textual, and accessibility practitioners.
How solid a rule is:
- convention: documented in a widely-adopted guide or standard.
- house style: one project's stated choice. Reasonable, not universal.
- unmarked: reasoning by analogy from graphical UI, with nothing behind it. Weigh it lower.
Terminal accessibility gets its own file, references/accessibility.md. There is no WCAG equivalent for terminals, so nothing there is a conformance floor. Read it anyway: it holds the one rule most likely to make a TUI unusable for someone.
1. Output Streams
CLI, convention. stdout carries the program's actual output. stderr carries everything about the run.
Do:
- Put primary output, the thing another program would consume, on stdout.
- Put logs, warnings, errors, and human-watched progress on stderr, so a pipe does not swallow them and they do not corrupt the data stream.
- Surface a subprocess's stderr to the end user rather than eating it.
curl's progress meter goes to stderr despite not being an error, because it is messaging about the run rather than the payload.
A machine-readable output format is a TRUST BOUNDARY, and the boundary rule reads as though it only covers input. Any user-supplied bytes entering a line-oriented or delimited format need quoting AT THE PRINTER, never a narrowing of what the input layer accepts. A key=value printer whose value is a path straight off argv, with nothing escaped, emits forged keys ahead of the real ones the moment that path contains a newline, at exit 0, and a first-wins reader believes them. Measured 2026-08-11 against a shipped flag: --source=$'/tmp/x\nparts=one' produced a verdict about a directory that does not exist. Quote or escape every value, or emit a format that carries its own quoting (json, NUL-delimited) rather than one that trusts its payload.
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.

terminal-ux is a skill published in the GitHub repository uwuclxdy/agenticat (5 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 3,323 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
