onboard

onboard is a command for coding agents from santif/openspec-go. It costs 0 tokens per session (3,252 once invoked), scanned A, original, no licence file.

A guided introduction to a complete OpenSpec workflow, carried out in the user's codebase. OpenSpec is a structured process for describing and implementing software changes.

In plain words
What is it for?
Learning OpenSpec from start to finish and applying it to a real change in a codebase.
Why use it?
It teaches the workflow while producing real work, so the user can learn from a complete example.

Token cost

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.

Security

Grade A, and why

onboard 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 3d 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.

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.

onboard is a command published in the GitHub repository santif/openspec-go (2 stars, last pushed 5mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 3,252 tokens. 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.
