apexyard: Skill for Claude Code

.claude/skills/tech-vision/SKILL.md

tech-vision is a skill for Claude Code from me2resh/apexyard. It costs 24 tokens per session (3,904 once invoked), scanned A, original, MIT.

A guided authoring workflow for writing a technical architecture vision. It helps document the desired system, the gap from the current system, the migration path, and what is outside the plan.

In plain words
What is it for?
Use it to create a reviewable architecture vision document for a system or portfolio of projects.
Why use it?
It prevents important architecture decisions from being left as empty template sections or vague aspirations.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; positional $N argument; mentions Claude Code.

This is me2resh/apexyard's own configuration. It tells Claude Code how to work on apexyard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything apexyard configures →

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Anti-Refusal · line 157
    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

Token cost

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.

Security

Grade A, and why

tech-vision 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 today.

The scan reads SKILL.md. This mod also ships 2 executable files (lint.sh, tests/smoke.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing rule

When this skill writes a durable artifact, read .claude/rules/writing-standard.md. Use the controlled technical writing profile.

/tech-vision — Interactive Architecture Vision Author

Walks the operator through the existing templates/architecture/vision.md (shipped in #224) section by section — instead of leaving the operator staring at an empty template — so the load-bearing sections (Anti-scope, Current-vs-Target, Migration path) actually get filled in honestly rather than left as aspirational stubs.

The output is a fully populated vision.md ready to commit. Markdown-only — the single graphical element (target-state C4 L1) renders inline via Mermaid on GitHub. No HTML, no SVG, no build step.

Why /tech-vision and not /vision? In a multi-stakeholder portfolio the word "vision" collides with product / company vision documents that Heads of Product and CEOs author in a different shape. The tech- prefix disambiguates this skill as the technical / architecture vision author. The output filename (vision.md) and template path (templates/architecture/vision.md) stay unchanged — only the slash-command carries the prefix.

Design rationale + sub-decisions: AgDR-0028.

Skill Role
/tech-vision (this skill) Authors the target-state + migration path — north-star architecture, prose + bulleted horizons
/c4 Static topology — current-state system + container diagrams
/dfd Data flow — trust boundaries + data classifications (input to /threat-model)
/sequence (template) Request-flow walkthroughs (auth handshake, payment flow)

Path resolution

Read the registry path via portfolio_registry, the per-project docs dir via portfolio_projects_dir, and the template path via portfolio_resolve_template — all from .claude/hooks/_lib-portfolio-paths.sh. Source the helper at the top of any bash block that touches those paths:

What ships with it

3 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.

Changes

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.
