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 | $0.00044 | $0.03519 |
| Opus 5.5 | $0.00018 | $0.01408 |
| Sonnet 5.5 | $0.00009 | $0.00704 |
| Haiku 4.5 | $0.00004 | $0.00352 |
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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect
Contract
| Field | Bound contract |
|---|---|
| Trigger | Design non-trivial code before implementation (greenfield), or improve an existing codebase's architecture (brownfield): survey for shallow modules, locate a seam, deepen a structure, harden with guardrails, or make code testable; or design one named module's interface, seams, and testability (targeted-module). |
| Authority | Reversible local: writes only named local design artifacts and, when the request permits, the selected design in the working tree; rollback is deleting or reverting those writes. No VCS, credential, paid, published, deployed, or remote mutation. |
| Side effect | A local design package; in implement mode, the accepted refactor, its tests, inline CONTEXT.md entries for established domain terms, and an optional local ADR the user accepts. |
| Done | An explicit design choice with tradeoffs and a coherent implementation plan are recorded. In brownfield implement mode: one chosen deepening candidate is grilled to resolution, its shallow path is replaced rather than layered, tests exercise the resulting interface, obsolete shallow tests and code are removed, and established domain terms and accepted decisions are recorded locally. In targeted-module mode: the chosen module presents a small coherent interface, hides implementation complexity, concentrates change locally, and is testable through explicit seams. |
Refusal
Not for visual architecture diagrams or HTML artifacts; use visual-diagram, which renders a self-contained visual; architect designs code structure (modules, interfaces, seams, depth) and produces a design package, not a rendered diagram. Not for deploy, remote, credential, publish, or irreversible changes; use shipping skills. Not for people-process or organizational architecture.
Inputs
mode:greenfield(design before implementation),brownfield(survey, deepen, or seams/testability/guardrails on existing code), ortargeted-module(one named module's interface, seams, and testability). Infer from the request; confirm when ambiguous.- Targeted-module: one named target module (a function, class, package, crate, or tier-spanning slice) with readable source and enough of its callers and tests to judge what they must know; optional: intended adapters, candidate seam locations, and the target language, inferred from the source when not stated.
What ships with it
5 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.

architect is a skill published in the GitHub repository OutlineDriven/outline-driven-development (53 stars, last pushed 22d ago), licensed Apache-2.0. It adds 44 tokens to every session and 3,519 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 2026-09-03.
Other skills, from other repositories
libfuzzer
Use when asked to build, run, or triage a coverage-guided C/C++ fuzz campaign on the libFuzzer or AFL++ engine. Not for harness design: use fuzz-harness-writing.
oss-fuzz
Use when enrolling a project in OSS-Fuzz, running its helper workflow locally, or reproducing an OSS-Fuzz report. Not for remote, credential, publish, deploy, or irreversible changes.
validation-first-driven
Use when building protocols, workflows, concurrent systems, or lifecycle-heavy state that needs explicit states, transitions, and temporal properties. Defines the state machine, encodes invariants in types, and for high-risk designs runs a TLA+ or Alloy model checker. Not for encoding domain models in types — use…
resolve
Use when addressing review feedback in analyze or reception mode, or handling GitHub PR feedback in autonomous, interactive, or summary mode for a named PR target. Classifies, applies, replies, or summarizes comments.
testing-handbook-generator
Use when the user asks to discover, generate, refresh, or validate skills from the Trail of Bits Testing Handbook or appsec.guide. Not for tasks that require source or remote-system changes.
mutation-campaign-configuration
Use when the user mentions mewt, muton, or mutation testing and asks to initialize, scope, estimate, configure, validate, or optimize a campaign before execution. Writes only the TOML config and validates readiness without generating mutants or touching source. Not for running the campaign: use mewt run separately.
