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 5.1 | $0.00077 | $0.00815 |
| Opus 5.5 | $0.00031 | $0.00326 |
| Sonnet 5.5 | $0.00015 | $0.00163 |
| Haiku 4.5 | $0.00008 | $0.00081 |
Grade A, and why
cli-for-agents 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLI for agents
Human-oriented CLIs often block agents: interactive prompts, huge upfront docs, and help text without copy-pasteable examples. Prefer patterns that work headlessly and compose in pipelines.
Non-interactive first
- Every input should be expressible as a flag or flag value. Do not require arrow keys, menus, or timed prompts.
- If flags are missing, then fall back to interactive mode—not the other way around.
Bad: mycli deploy → ? Which environment? (use arrow keys)
Good: mycli deploy --env staging
Discoverability without dumping context
- Agents discover subcommands incrementally:
mycli, thenmycli deploy --help. Do not print the entire manual on every run. - Let each subcommand own its documentation so unused commands stay out of context.
- If the CLI needs extensive agent guidance, keep the default skill/help thin and point to versioned, CLI-served instructions. See
references/agent-browser-runtime-skills.md.
--help that works
- Every subcommand has
--help. - Every
--helpincludes Examples with real invocations. Examples do more than prose for pattern-matching.
Options:
--env Target environment (staging, production)
--tag Image tag (default: latest)
--force Skip confirmation
Examples:
mycli deploy --env staging
mycli deploy --env production --tag v1.2.3
mycli deploy --env staging --force
stdin, flags, and pipelines
- Accept stdin where it makes sense (e.g.
cat config.json | mycli config import --stdin). - Avoid odd positional ordering and avoid falling back to interactive prompts for missing values.
- Support chaining:
mycli deploy --env staging --tag $(mycli build --output tag-only).
Fail fast with actionable errors
- On missing required flags: exit immediately with a clear message and a correct example invocation, not a hang.
Error: No image tag specified.
mycli deploy --env staging --tag <image-tag>
Available tags: mycli build list --output tags
What ships with it
2 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.

cli-for-agents is a skill published in the GitHub repository heyAyushh/stacc (3 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 815 once invoked, about $0.0003 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 2026-08-31.
