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 | $0.00085 | $0.01263 |
| Opus 5 | $0.00043 | $0.00632 |
| Sonnet 5 | $0.00017 | $0.00253 |
| Haiku 4.5 | $0.00009 | $0.00126 |
Grade A, and why
tech-blueprinting 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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tech Blueprinting Workflow
A structured three-stage collaborative workflow for producing technical documents. Stages target predictable failure modes: missing context, disorganized drafting, and author blind spots.
Dependencies
The core writing workflow needs only file read/write access in the user's chosen project or output folder. The visual companion is optional and requires Node.js, shell support, and a local browser.
Loading Maps
| Resource | File | Load when |
|---|---|---|
| Visual Companion | workflows/visual-companion.md |
User accepts visual companion offer. |
| Spec Reviewer | agents/spec-reviewer.md |
After near completion, before reader testing. |
| Reader Tester | agents/reader-tester.md |
Stage 3 reader testing dispatch. |
| README Workflow | workflows/readme-write.md |
User wants to write, update, or refresh a README. |
| README Template | references/readme-template.md |
README workflow drafting. |
| README Self-Review | references/readme-self-review.md |
README workflow quality check. |
| Plan Template | references/plan-template.md |
Document type is an implementation plan. |
| Test Level Protocol | shared/test-level-protocol.md |
Implementation assertions plus boundary signals. |
| Code Organization | shared/code-organization.md |
Multi-file implementation or architecture spec. |
Test Level Gate
Load shared/test-level-protocol.md and evaluate when any boundary signal is present in an implementation-oriented spec: subprocess spawn, IPC or HTTP boundary, filesystem state written then read, lock or PID coordination, external tool, cross-language boundary, CLI entrypoint, public schema, config, API payload, or file format change.
Skip when the work is a single module with pure logic and no I/O. Decide the test level before drafting and include the recommendation in the plan.
Document Type Routing
Before offering the three-stage workflow, check for a specialized workflow match.
| Signal | Route | Why |
|---|---|---|
| User mentions README, usage docs, refresh docs, or document this skill | Load workflows/readme-write.md |
READMEs follow a fixed source-reading and template workflow. |
| User mentions implementation plan, dev plan, task breakdown, or execute-ready plan | Load references/plan-template.md before drafting |
Plans need task shape, commands, boundaries, and TDD-ready steps. |

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.

tech-blueprinting is a skill published in the GitHub repository nanparth/ai-skill-hub (23 stars, last pushed 18d ago), licensed MIT. It adds 85 tokens to every session and 1,263 once invoked, about $0.0004 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 2026-08-30.
