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 | $0.00039 | $0.01150 |
| Opus 5.5 | $0.00016 | $0.00460 |
| Sonnet 5.5 | $0.00008 | $0.00230 |
| Haiku 4.5 | $0.00004 | $0.00115 |
Grade A, and why
run-ralph 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.
How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run Ralph — Autonomous Task Loop
Runs a markdown task file (checkboxes) as an autonomous loop. Each task gets a fresh agent with a fresh context window. After completing a task, the agent commits, the orchestrator marks it done, and schedules the next. Messages you with progress between iterations.
Starting a Run
1. Create or identify the task file
The task file is standard markdown with checkboxes:
# Feature: User Authentication
- [ ] Create user model with email and password fields
POST /api/users table with bcrypt hashing
Unit tests for model validation
- [ ] Add login endpoint with JWT
POST /api/login returns token
Returns 401 on invalid credentials
- [ ] Add registration endpoint
POST /api/register with email verification
Duplicate email returns 409
Rules for good task files:
- Each task must be completable in one agent session (one context window)
- Include acceptance criteria as indented lines below each checkbox
- Tasks run in order — put dependencies first
- Already-checked items
[x]are skipped
2. Get the chat JID
sqlite3 store/messages.db "SELECT jid FROM registered_groups WHERE folder = 'main' LIMIT 1;"
3. Estimate iterations
Read the task file and assess each unchecked task:
Simple tasks (1 iteration each):
- Config changes, env vars, small edits
- Adding a single file or endpoint
- Running a command and reporting results
Medium tasks (2 iterations each):
- New feature with tests
- Integration with an external service
- Refactoring across multiple files
Complex tasks (3 iterations each):
- Multi-file architectural changes
- New system with several moving parts
- Anything with "and also" or multiple acceptance criteria
Add up the estimates and add 2 for retry buffer. Tell the user:
"You have N tasks. I'd estimate M iterations based on complexity:
- 3 simple (3 iterations)
- 2 medium (4 iterations)
- 1 complex (3 iterations)
- Total: 12 iterations (10 + 2 buffer)
Want me to run with that, or set a different limit?"
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.

run-ralph is a skill published in the GitHub repository b1rdmania/ghostclaw (84 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 1,150 once invoked, about $0.0002 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 2026-08-30.
