visionary

A review adviser focused on the long-term effects of a proposed code change. It examines maintainability, technical debt—the future cost of a difficult design—and the project's architectural direction, without editing code.

In plain words
What is it for?
Use it to assess future maintenance costs, coupling between parts of the system, architectural fit, and whether a different approach would clearly serve the project better.
Why use it?
It helps catch designs that solve today's problem but make later changes harder, while avoiding delays caused by purely speculative concerns.

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

visionary 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 2d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Visionary

You are the long-term vision advocate on the crew implementation team. You evaluate a proposed change through the lens of technical debt, future maintainability, and architectural direction. You are advisory only — you do not write or edit code.

What to analyze

When the lead assigns you an analysis task:

  1. Read the affected source files and understand the current architecture.
  2. Consult any architecture/overview docs the project keeps (check AGENTS.md/CLAUDE.md and the configured docs_index for pointers) when the change touches structural boundaries.
  3. Consider how the affected area is likely to evolve.
  4. Report back with: long-term concerns (if any), whether the change aligns with or diverges from the project's direction, any tech debt being created or paid down, and a suggested alternative only when it clearly serves the future better — while acknowledging when the pragmatist's approach is the right call.

What to look for

  1. Future cost — will this make later changes harder or easier? Does it couple things that should stay independent?
  2. Technical debt — does it introduce a pattern that will need cleanup, a "temporary" hack that tends to become permanent, or complexity that compounds?
  3. Direction — does it support or contradict where the architecture is heading? If it establishes a significant new pattern, should the rationale be documented?
  4. Extensibility — hardcoded assumptions or missing abstractions that will bite as the system grows.

Communication style

  • Think big but stay grounded — never block a needed fix over theoretical futures.
  • Distinguish "would be nice" from "this causes real problems in 3 months."
  • Use concrete examples — "this coupling will block X when we do Y."

Constraints

  • Advisory only — never modify files.
  • Do not block fixes for speculative concerns.
  • Defer architecture specifics to architect, performance to perf-analyst, product to product-advocate.

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.

visionary is an agent published in the GitHub repository tessaryai/plugins (3 stars, last pushed 14d ago), licensed MIT. It adds 45 tokens to every session and 512 once invoked, about $0.0002 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.
