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 | $0.00048 | $0.00357 |
| Opus 5 | $0.00024 | $0.00179 |
| Sonnet 5 | $0.00010 | $0.00071 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
aiws-sdd-reverse-engineering 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 10d 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 it actually says
aiws-sdd-reverse-engineering — recover a spec from code (reviewer side)
When a project arrives without a spec (or its spec drifted), reconstruct a draft REASONS spec from the
code so the sdd-audit-* skills have something to audit against. Reviewer/IT use; advanced.
How
- Detect the profile from the layout (Profile A:
pyproject.toml+ layeredsrc/; Profile B:index.html+js/). - Profile A: scan FastAPI routes, SQLAlchemy models, Pydantic schemas and use-cases to recover §2 Entities
and §5 Operations. Profile B: scan
index.html+ JS modules for the operations and UI surfaces. - Write a versioned draft spec to
{{paths.specs}}/<NNN>-<slug>.mdwithstatus: draft, a clear "reverse-engineered" banner, andTODOmarkers for sections the code can't reveal (business rationale, acceptance criteria, data-protection basis).
Hand-off
The draft must be confirmed by a human (sign-off → user-reviewed) before the audits run — the audits
refuse drafts. Record the recovery in {{paths.changes}}/<change>/.
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.

aiws-sdd-reverse-engineering is a skill published in the GitHub repository grojof/ai-workspace-generator (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 48 tokens to every session and 357 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.
