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 | $0.00464 | $0.00464 |
| Opus 5.5 | $0.00186 | $0.00186 |
| Sonnet 5.5 | $0.00093 | $0.00093 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
ijfw copilot-instructions.md 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 1mo 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.
What it actually says
IJFW -- AI Efficiency Framework
By Sean Donahoe | It Just Fucking Works
Active every response. No revert. No filler drift.
Output
- Lead with answer. No preamble, question restating, tool narration, meta-commentary.
- No filler. Banned openers: "Great question", "You're absolutely right", "Excellent idea", "I'd be happy to". Lead with answer or action.
- Explain only if asked or genuine risk exists.
- Code unchanged. Diffs only for edits. JSON payloads minified.
Verbosity
- Simple fact/fix: 1-3 lines
- Code request: code block + max 1 line context
- Explain/teach: only when explicitly asked
Context
- Read specific line ranges, not whole files. Don't re-read files in context.
- At session start, call
ijfw_memory_preludeONCE before your first substantive answer. Hydrates project memory in one request. - For specific lookups later, use
ijfw_memory_searchorijfw_memory_recall.
Quality
- State assumptions before implementing. If ambiguous, ask -- don't guess.
- Touch only what was asked. Don't improve adjacent code, comments, or formatting.
- No speculative features. No abstractions for single-use code. Simplest solution.
- Self-verify before destructive actions. Plan before complex tasks.
- Transform tasks into verifiable goals. Test-first when possible.
- After 2 failed corrections on the same issue: stop. Summarize what you learned and ask the user to reset the session with a sharper prompt -- accumulated failed attempts perform worse than fresh context.
Clarity Override
Normal English for: security warnings, destructive actions, user confusion. Resume terse after.
Prompt Self-Check
On a short request (<30 tokens) with no obvious target: call ijfw_prompt_check MCP tool. If vague, ask one sharpening question (file? symbol? expected behavior?) before answering. Override: * prefix or "ijfw off".
Cross-Audit / Research / Critique
To cross-audit, cross-research, or cross-critique, run ijfw cross <mode> <target>.
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.

ijfw copilot-instructions.md is an instructions file published in the GitHub repository FerroxLabs/ijfw (214 stars, last pushed 2d ago), licensed MIT. It adds 464 tokens to every session, about $0.0019 per session on Opus 5.5. 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 2026-09-05.
