Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00133 | $0.04285 |
| Opus 5 | $0.00067 | $0.02142 |
| Sonnet 5 | $0.00027 | $0.00857 |
| Haiku 4.5 | $0.00013 | $0.00428 |
Grade A, and why
haiku-pilot 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 11d 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 — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Haiku Pilot — Default-Haiku Execution Playbook
Thesis
Weak planner + strong delegation > strong planner doing everything.
AgentOpt (arxiv 2604.06296): On HotpotQA, Opus alone = 31.71%; Ministral 3 8B planner + Opus solver = 74.27%. Augment Code eval (2026-04): Best-quality AGENTS.md provides performance gain equivalent to one model tier (Haiku → Sonnet effective).
→ Default parent session to Haiku 4.5; aggressively delegate to sub-agents; escalate only on quantitative gate trigger.
"Documentation / process design improvements ≥ model upgrade" is the engineering basis. Blindly upgrading models in multi-stage pipelines often reduces performance (planner doesn't delegate).
Per-Session Pre-flight (run once per task)
1. Reference Pattern Technique
| ❌ Verbal description | ✅ Point to a file |
|---|---|
| "Write a login-like function" | "Follow the pattern in src/auth/login.ts" |
| "Add a hook similar to useUser" | "Pattern: hooks/useUser.ts:42-78" |
Why it matters: Haiku diverges easily from abstract descriptions; pointing to a concrete file = strongest possible context.
2. Think-Before-Coding (compensates Haiku tendency)
Before implementation, output:
- 1–2 sentence task understanding restatement (your interpretation, not parroting)
- Key assumptions (≥ 1, prefixed with "Assumption: ...")
- If multiple interpretations are reasonable → list options for user confirmation, don't pick one yourself
Source:
core.md§ "Think-Before-Coding". Haiku tends to skip this step; this SKILL enforces it.
3. Diff-Review Pledge
Before declaring "complete", run:
git diff --stat
git status
Explain each change in one sentence. Catches Haiku quietly modifying out-of-scope files (surgical-changes discipline).
4. Citation Anchor Enforcement
When citing wiki / docs / spec for numbers, conclusions, or anti-patterns, attach a structured anchor:
(P0X §Y.Z)— paper section ref (e.g.(P03 §4.2)) — preferred for paper-grounded citations(<source> Step N)— wiki step number(anti-pattern #N)— wiki anti-pattern number(<file>:line-range)— code / config line ref
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.

haiku-pilot is a skill published in the GitHub repository zeuikli/claude-pilot-suite (24 stars, last pushed 4mo ago), licensed MIT. It adds 133 tokens to every session and 4,285 once invoked, about $0.0007 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 2026-08-30.
