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 | $0.00039 | $0.00255 |
| Opus 5 | $0.00019 | $0.00128 |
| Sonnet 5 | $0.00008 | $0.00051 |
| Haiku 4.5 | $0.00004 | $0.00026 |
Grade A, and why
onboarding 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 yesterday.
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 it actually says
Onboarding
Fires when the user is starting fresh with this plugin or migrating from obra/superpowers.
Procedure
- Tell the user to run
/bootstrapin their project root. It:- Creates
docs/specs/anddocs/plans/if missing. - Detects legacy
docs/superpowers/specs/anddocs/superpowers/plans/from obra and printsgit mvcommands to migrate. - Prints a CLAUDE.md snippet to consider and hook-template copy commands.
- Is idempotent — safe to re-run.
- Creates
- After
/bootstrap, point them at the plugin README for the full inventory of slash commands and skills.
Example
User: "I just installed developersDevelopers, what now?"
Response: "Run /bootstrap in your project root — it bootstraps docs/specs/ and docs/plans/, prints any migration steps if you have legacy obra paths, and shows the next moves."
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.

onboarding is a skill published in the GitHub repository vrennat/developersDevelopers (2 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 255 once invoked, about $0.0002 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.
