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 | $0.00060 | $0.01716 |
| Opus 5 | $0.00030 | $0.00858 |
| Sonnet 5 | $0.00012 | $0.00343 |
| Haiku 4.5 | $0.00006 | $0.00172 |
Grade A, and why
writing-skills 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 11d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing skills
Reuse the existing owner
Inspect existing skill catalogs before creating a package. For repository work, search the target catalog and every relevant source catalog in the authorized workspace. For authorized live-library work, use Rundesk's catalog and skill listings; do not open the live library to bypass the task's access boundary. Read the descriptions of plausible matches, then their bodies and relevant references before deciding.
Extend the existing owner when the requested capability shares its user intent, workflow, and authority. Add a supporting script, reference, or test there instead of creating a second routing surface. Create a new skill only when the capability needs distinct routing, judgment, authority, or proof; record that distinction so a nearby name is not treated as justification by itself.
Choose the artifact
- A skill is the instruction boundary: when to act, what judgment to apply, which procedure to follow, and how to prove the outcome.
- A workflow script is the deterministic mechanism for repeated local transformation, validation, or orchestration.
- An integration adds an external-service boundary: credentials, accounts, network failures, permissions, or remote effects.
Keep one-off automation in its project and one agent's private repeated command in that agent's scripts area. Package a script in a skill only when future turns need routing or judgment to use it. Do not replace deterministic code with prose an agent must reinterpret.
Read Reusable workflow scripts before shipping any reusable script. Also read External-service integrations when it uses credentials, profiles, OAuth, a network, or remote effects.
Place it safely
Create a private skill in local only when live creation or installation is authorized. For a
draft, review, repository change, or isolated test, stay in the named workspace or temporary
directory; do not inspect or change the live library to discover where the result might later go.
What ships with it
3 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.

writing-skills is a skill published in the GitHub repository rundesk-ai/rundesk-cli (6 stars, last pushed 7d ago), licensed MIT. It adds 60 tokens to every session and 1,716 once invoked, about $0.0003 per session on Opus 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.
