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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.04868 |
| Opus 5.5 | $0.00015 | $0.01947 |
| Sonnet 5.5 | $0.00008 | $0.00974 |
| Haiku 4.5 | $0.00004 | $0.00487 |
Grade A, and why
architect 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 — 426 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect
Architecture and implementation planning before coding.
Use this skill to spend deliberate reasoning budget on the plan, while leaving the implementation itself free to use a cheaper/faster model when the plan is clear.
When to Use
Use /architect for tasks with architectural uncertainty, high blast radius, or expensive
mistakes:
- Cross-module, cross-service, or multi-repo changes
- New abstractions, boundaries, workflows, or domain model changes
- Database/schema migrations or data backfills
- Public APIs, event schemas, contracts, SDKs, or integrations
- Auth, permissions, privacy, compliance, or security-sensitive work
- Performance, scalability, resiliency, or concurrency-sensitive changes
- Hard-to-reverse decisions
- Ambiguous requirements or multiple plausible approaches
- Work likely to split into several commits, beads, tickets, or PRs
- Any task where the user explicitly asks for architecture, design, planning, or approach
Usually skip it for:
- Small bug fixes with obvious locality
- Copy/text tweaks
- Simple CSS/layout adjustments
- Mechanical dependency bumps
- Straightforward test additions
- Refactors whose pattern and scope are already obvious
Usage
/architect <task, bead id, Jira key, or question>
/architect ABC-123
/architect bd-456
/architect --tier premium <task>
/architect --tier second-opinion <task>
/architect --tier all-in <task>
/architect --no-prompt <task>
Planning Tiers
Do not expose model churn as the primary interface. Ask for a planning tier when the user has not specified one and the choice matters.
| Tier | Meaning | Use when |
|---|---|---|
standard |
Standard coding tier | Moderate planning, low ambiguity |
premium |
Premium reasoning tier, preferring subscription/OAuth routes | Architectural uncertainty or costly mistakes |
second-opinion |
In-session draft + one vendor-independent /second-opinion validate-plan review |
Need an independent validation pass |
all-in |
Premium draft + one bounded /second-opinion validate-plan --agent quorum --panel focused review batch |
High-risk, cross-service, security, data migrations |
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.

architect is a skill published in the GitHub repository flurdy/agent-skills (9 stars, last pushed yesterday), licensed MIT. It adds 38 tokens to every session and 4,868 once invoked, about $0.0002 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.
