Agent Scripts is a repository of shared instructions, reusable skills, helper scripts, and local safeguards for coding-agent workflows across multiple workspaces. It is for maintaining common agent behavior and portable development utilities between repositories.
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 high
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 →
- high System Prompt Leakage · line 35 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
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 | $0.00022 | $0.00855 |
| Opus 5.5 | $0.00009 | $0.00342 |
| Sonnet 5.5 | $0.00004 | $0.00171 |
| Haiku 4.5 | $0.00002 | $0.00085 |
Grade A, and why
create-cli 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create CLI
Design CLI surface area (syntax + behavior), human-first, script-friendly.
Do This First
- Read
agent-scripts/skills/create-cli/references/cli-guidelines.mdand apply it as the default rubric. - Upstream/full guidelines: https://clig.dev/ (propose changes: https://github.com/cli-guidelines/cli-guidelines)
- Ask only the minimum clarifying questions needed to lock the interface.
Clarify (fast)
Ask, then proceed with best-guess defaults if user is unsure:
- Command name + one-sentence purpose.
- Primary user: humans, scripts, or both.
- Input sources: args vs stdin; files vs URLs; secrets (never via flags).
- Output contract: human text,
--json,--plain, exit codes. - Interactivity: prompts allowed? need
--no-input? confirmations for destructive ops? - Config model: flags/env/config-file; precedence; XDG vs repo-local.
- Platform/runtime constraints: macOS/Linux/Windows; single binary vs runtime.
Deliverables (what to output)
When designing a CLI, produce a compact spec the user can implement:
- Command tree + USAGE synopsis.
- Args/flags table (types, defaults, required/optional, examples).
- Subcommand semantics (what each does; idempotence; state changes).
- Output rules: stdout vs stderr; TTY detection;
--json/--plain;--quiet/--verbose. - Error + exit code map (top failure modes).
- Safety rules:
--dry-run, confirmations,--force,--no-input. - Config/env rules + precedence (flags > env > project config > user config > system).
- Shell completion story (if relevant): install/discoverability; generation command or bundled scripts.
- 5–10 example invocations (common flows; include piped/stdin examples).
Default Conventions (unless user says otherwise)
-h/--helpalways shows help and ignores other args.--versionprints version to stdout.- Primary data to stdout; diagnostics/errors to stderr.
- Add
--jsonfor machine output; consider--plainfor stable line-based text. - Prompts only when stdin is a TTY;
--no-inputdisables prompts. - Destructive operations: interactive confirmation + non-interactive requires
--forceor explicit--confirm=.... - Respect
NO_COLOR,TERM=dumb; provide--no-color. - Handle Ctrl-C: exit fast; bounded cleanup; be crash-only when possible.
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.
- 1mo ago First seen · 89 lines · 22 tokens per session scan A e38bccc69413
create-cli is a skill published in the GitHub repository steipete/agent-scripts (7,379 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 855 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 2026-08-30.
