perspective is a skill for Claude Code from YG3-ai/quill. It costs 41 tokens per session (657 once invoked), scanned A, original, MIT.

A skill that asks Quill, an outside helper, for an additional viewpoint on the problem you are exploring.

In plain words
What is it for?
Use it to examine a project or idea from a different perspective and expand the possible approaches.
Why use it?
It gives you another angle when you want to broaden your thinking, even when nothing is obviously wrong.

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

perspective scanned grade A with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The developer just typed /quill:perspective — they're not stuck or frustrated, they're exploring. They want to layer in another vantage point alongside yours. Their note: "$ARGUMENTS"

This is additive, not corrective. Don't try to find what's wrong. Bring in something that opens up the possibility space.

Step 1 — Frame your current thinking

Look back at the last 6-10 exchanges in this session. In 2-3 sentences, describe:

  • What the developer is exploring or building
  • Your current angle on it (what you're focused on, what you've been proposing, what you find interesting about the problem)
  • Where the thinking might benefit from another vantage point

Length limit: keep your framing under 600 characters total. The bridge caps inputs at 1000 chars and will truncate longer messages.

Step 2 — Ask Quill for the additional perspective

Use this command, substituting your framing from Step 1 for <YOUR FRAMING>:

python3 -c "
import json, urllib.request, sys
msg = sys.argv[1]
payload = json.dumps({'message': msg}).encode()
req = urllib.request.Request('http://127.0.0.1:9000/perspective', data=payload, headers={'Content-Type': 'application/json'})
try:
    with urllib.request.urlopen(req, timeout=180) as r:
        data = json.loads(r.read())
    if data.get('welcome'):
        print('=== WELCOME ===')
        print(data['welcome'])
        print('=== END WELCOME ===')
        print()
    print(data['reply'])
except Exception as e:
    print(f'BRIDGE UNAVAILABLE: {e}')
" "<YOUR FRAMING>"

If you see BRIDGE UNAVAILABLE, the local advisor server isn't running. Tell the developer to check the plugin's status (it should auto-start when the plugin is enabled — see the plugin README for the recovery command) and stop here.

First-install note: if the output contains === WELCOME === / === END WELCOME === markers, this is the developer's very first Quill invocation. Show the welcome text (between the markers) verbatim as a brief preface in Step 3, before the three-paragraph dialogue. After this session it will never appear again — don't paraphrase or skip it.

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.
