Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00122 | $0.00810 |
| Opus 5.5 | $0.00049 | $0.00324 |
| Sonnet 5.5 | $0.00024 | $0.00162 |
| Haiku 4.5 | $0.00012 | $0.00081 |
Grade A, and why
handing-off-to-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 2d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handing Off to Engineering
Shared exit for all paths: handoff-junction.mmd.
Contents
Constraints
- Source grounding: never invent requirements; cite the capture for every major claim.
- One Tier-3 rule (handoff guide): Tier 3 means a formal engineering cycle, never "deploy after review". Write
tier3-risk-summary.mdfirst and put it at the top of the package. Q5 alone is Tier 2 with ethics review. - Final package: no
[NEEDS HUMAN INPUT]; unresolved items become[UNCONFIRMED]with a reason plus a## Deferred Gapslist; every readiness check carries evidence; emitPHASE 4 COMPLETE. - Technical discovery is read-only: no source changes outside
exploration/. - Control plane: for structured engineering name the
os-control-intakeskill; do not import or path intoagent-agentic-os. - Pick runtime and model through the
cli-agentskill; never name models.
Quick start
From this skill's folder:
python3 scripts/technical_diagnostic_engine.py --task-id <id> --title "<title>" --output exploration/DIAGNOSTIC_BRIEF.md
python3 ../running-exploration-cycle/scripts/validate_phase_gate.py 4
Workflow
- Scribe: fill any missing capture via
capturing-business-requirements. - Assess the five risk questions; choose the delivery path and format; write
exploration/handoffs/handoff-package.md. - Placeholder sweep, then reader test (three blocker questions for the consumer).
- Validate, get SME approval, route: self-deploy, review, formal engineering via
os-control-intake, or defer. - Re-entry: quote the engineering ambiguity verbatim, draft a new session brief for
running-exploration-cycle.
Verification
python3 -m pytest scripts -q
Acceptance criteria: acceptance-criteria.md.

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.

handing-off-to-engineering is a skill published in the GitHub repository richfrem/agent-plugins-skills (7 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 810 once invoked, about $0.0005 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 2026-10-24.

triage
Triage a GitHub repository's open issues by finding exact duplicates, rejecting evidenceably off-base requests, requesting concrete clarification, applying only existing labels, and opening a linked root-cause issue when multiple reports share one underlying invariant failure.

Hand one exact agent-ready ticket to the central Factory runtime over the configured SSH forced-command boundary. Use when an operator asks to hand off an existing ticket or a prose request instead of implementing it in the current session.
