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

feature-radar-ref 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 27d 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.

Add Reference

Deep Read

Behavioral Directives

Workflow

  1. Identify the source — ask the user what they observed:
    • Interesting project, technique, or creative approach?
    • Ecosystem trend or emerging pattern?
    • Notable feature or solution from a related project?
    • User comparison, feedback, or question?
    • Research, article, or talk with relevant insights?
  2. Gather context — URL, date, key details. If the user provides a GitHub URL, fetch the issue/PR for full context.
  3. Classify — determine the right file:
    • Existing reference file → append a new entry
    • New topic → create .feature-radar/references/{topic}.md
  4. Assess impact — before writing to references/, answer each question:
    • New opportunity or feature idea? → state yes/no, suggest file if yes
    • Way to enhance existing features? → state yes/no, suggest update if yes
    • Ecosystem trend? → state yes/no, suggest specs/ecosystem-trends.md update if yes
  5. Checkpoint — State what was written and the impact assessment results. Ask: "I've updated references/{topic}.md. Does this look correct, or should I adjust anything?" Wait for user confirmation before proceeding.
  6. Update base.md — increment the references count in Tracking Summary

File Format

Use the format defined in ../feature-radar/references/SPEC.md § 3.5 (references/{topic}.md).

Naming Convention

Name by the subject being tracked, not the event:

  • Good: vercel-skills-ecosystem.md, agent-path-conventions.md, cli-ux-patterns.md
  • Bad: 2026-02-18-update.md, interesting-finding.md

Guidelines

  • Always cite source URLs and dates for traceability.
  • Append new entries chronologically to existing files — don't create a new file per observation.
  • Be objective. Record what happened, then assess implications separately.
  • If the observation reveals an unmet need or innovation opportunity, proactively suggest creating an opportunity.

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.
