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 | $0.00131 | $0.01376 |
| Opus 5 | $0.00066 | $0.00688 |
| Sonnet 5 | $0.00026 | $0.00275 |
| Haiku 4.5 | $0.00013 | $0.00138 |
Grade A, and why
plan-architecture 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 5d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
plan-architecture workflow (v3)
Overview
1-phase sub-workflow mapping CLAUDE.md "⚠️ 复杂架构前 — plan-eng-review" onto harnessed runtime (Phase v3.0-3.4 W0.4 — D-04 Stage ② Plan 二层 + D-12 gstack 治理关卡 + Pattern A sub-workflow ship)。
| phase | id | upstream | model | capability | gate |
|---|---|---|---|---|---|
| 1 | 01-plan-eng-review |
gstack | opus | {{ capabilities.plan-eng-review.cmd }} |
gate: phase.is_complex_architecture == true (literal expr) |
Capability refs
Sister workflows/capabilities.yaml entries:
plan-eng-review— Bucket 7 gstack 33 optional (impl: gstack, cmd: /plan-eng-review)- Pattern A E.2 LOCK: no
gstack-prefix per CLAUDE.md gstack skill routing convention
- Pattern A E.2 LOCK: no
Gate ref
Inline literal expr phase.is_complex_architecture == true — sister capability
fires_when clause verbatim。W2.2 backfill 可加 judgments/phase-gate.yaml
trigger is-complex-architecture 重构 ref。
Invocation
- Slash command:
/plan-architecture <name>(afterharnessed setup)
Routing rules
触发条件 (sister CLAUDE.md "⚠️ 复杂架构前"):
- 涉及多模块跨界设计 (≥3 模块协同)
- 新引入核心抽象 (新 framework / 新数据模型 / 新协议)
- 性能 / scaling 关键路径
- 引入显著技术债 / migration 风险
How to invoke
!harnessed checkpoint intent plan-architecture
The banner above (when present) means this invocation is REGISTERED with the engine (an intent marker) — not yet compliant: the steps below (prompt → spawn → checkpoint complete) resolve it, and a per-turn
<workflow-intent>reminder persists until they run.
The numbered sequence below is the state machine — execute it with Bash. Do NOT improvise an equivalent flow from the Overview above: freelancing bypasses the engine (no ledger, no evidence guard). harnessed gives you the spawn-ready prompt; YOU spawn the subagent with a CC-native Task / Agent tool (keeps the session responsive + lets clarification round-trips reach the user).
Do NOT pipe to harnessed run plan-architecture — that is the CI/headless path (in-process SDK spawn
that blocks the session inside Claude Code).
What ships with it
2 files 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.

plan-architecture is a skill published in the GitHub repository easyinplay/harnessed (2 stars, last pushed 9d ago), licensed Apache-2.0. It adds 131 tokens to every session and 1,376 once invoked, about $0.0007 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.
