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 | $0.00125 | $0.01402 |
| Opus 5 | $0.00063 | $0.00701 |
| Sonnet 5 | $0.00025 | $0.00280 |
| Haiku 4.5 | $0.00013 | $0.00140 |
Grade A, and why
grok-build 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Grok Build Orchestration
The coding assistant is the orchestrator: it plans, writes self-contained task specs,
dispatches them to Grok Build headlessly, reviews every diff, and owns the final result.
Grok is the fast, cheap executor. Full CLI details and verified behaviors: references/cli.md.
When to delegate vs keep with the orchestrator
| Delegate to Grok | Keep with the orchestrator |
|---|---|
| Plan tasks with clear acceptance criteria | Ambiguous requirements, architecture decisions |
| Boilerplate, scaffolding, CRUD | Deep cross-file debugging |
| Mechanical refactors | Security-sensitive code |
| Test writing from clear specs | Anything touching production infrastructure |
| UI components from mockups/specs | Tasks where writing the spec ≈ doing the work |
When in doubt, keep it with the orchestrator.
Session preflight (once, before the first dispatch)
grok update --check --json— ifupdateAvailableis true, rungrok updateand confirm withgrok --version.grok models— if it errors or reports logged out, STOP and ask the user to rungrok login.
Per-task loop (sequential — the default)
-
Spec. Write a self-contained task file (template below) to a temp directory OUTSIDE the target repo — the harness scratchpad if one is available, else the OS temp dir. Never write it inside the target repo. Grok has zero conversation context: no one-liner prompts, ever.
- POSIX:
mkdir -p "${TMPDIR:-/tmp}/grok-specs", then writetask.mdthere. - Windows (PowerShell):
New-Item -ItemType Directory -Force "$env:TEMP\grok-specs", then writetask.mdthere.
- POSIX:
-
Clean state. No uncommitted source changes — commit or stash first, so the post-run diff is exactly Grok's work. Ignore build artifacts (
__pycache__,dist/, etc.); if they show ingit status, they're usually just un-gitignored, not your concern. Never dispatch on a dirty source tree. -
Dispatch.
POSIX:
grok --prompt-file <task-file> \ --output-format json \ --always-approve \ --max-turns 30 \ --cwd <repo>
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.

grok-build is a skill published in the GitHub repository sanjay3290/ai-skills (422 stars, last pushed today), licensed Apache-2.0. It adds 125 tokens to every session and 1,402 once invoked, about $0.0006 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 2026-08-30.
