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 | $0.00090 | $0.00668 |
| Opus 5.5 | $0.00036 | $0.00267 |
| Sonnet 5.5 | $0.00018 | $0.00134 |
| Haiku 4.5 | $0.00009 | $0.00067 |
Grade A, and why
start 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Start
The onboarding entrypoint for the ai-engineering-workspace kit. This does not
reimplement anything: it points you at the one wizard that generates your
persona, scripts/create-persona.sh (or .ps1 on Windows).
What the persona wizard does
It stitches your identity header onto the fixed methodology canon and writes
three gitignored files under persona/:
persona.md— your full personaCLAUDE.md— the condensed version for~/.claude/CLAUDE.mdrecommended-skills.md— which shipped skills to reach for first
It asks only about the identity header — discipline, seniority, workflow, then
role, stack, and tooling. The methodology canon (simplicity ladder, RFC/ADR
format, PR-review tiers, verification, git rules) is fixed and identical for
everyone. Press Enter to accept each default; staff + fullstack + architecture-focused reproduces the shipped baseline.
Steps
- Ask which shell the user is on if it is not already obvious: a POSIX shell (macOS/Linux) or PowerShell (Windows). Do not assume.
- Give the exact command for that shell (below), and let the user run it in their own terminal so the interactive prompts work.
- Point at the next step: once the persona files exist, run the per-tool installer(s) — see the top-level README. The Claude installer also runs the wizard automatically on first install if it was skipped.
macOS / Linux (POSIX shell)
scripts/create-persona.sh # interactive; Enter accepts each default
scripts/create-persona.sh --defaults # accept everything, no prompts
Windows (PowerShell)
powershell -NoProfile -File .\scripts\create-persona.ps1
powershell -NoProfile -File .\scripts\create-persona.ps1 -Defaults
Rules
- Do not run the wizard or edit files yourself unless the user explicitly asks. It is interactive and writes the user's personal files; hand over the command and let them drive.
- Do not re-ask the wizard's questions here. The wizard owns that flow; this skill only explains it and provides the command.
- If the user asks what an axis means, answer briefly — discipline shapes the
background framing and recommended skills; seniority shapes how the assistant
treats them; workflow foregrounds skills in the recommended-skills view — and
point to
persona/README.mdfor the full picture.
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.
- 1mo ago First seen · 63 lines · 90 tokens per session scan A 33f4e9137dd9
start is a skill published in the GitHub repository yuri-semenenko/ai-engineering-workspace (4 stars, last pushed 1mo ago), licensed MIT. It adds 90 tokens to every session and 668 once invoked, about $0.0004 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.
