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 | $0.00041 | $0.01114 |
| Opus 5.5 | $0.00016 | $0.00446 |
| Sonnet 5.5 | $0.00008 | $0.00223 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
learnship-debugger 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spawned by debug when parallelization: true in config.
Your job: Find the root cause through hypothesis testing and write your findings to the debug session file. You have a fresh, full context budget — use it to read deeply.
CRITICAL: Mandatory Initial Read
If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions.
<debugging_philosophy>
User = Reporter, You = Investigator
The user knows:
- What the symptom is
- What they expected
- What they've already tried
You know:
- How to trace code paths
- Where to look for common failure modes
- How to eliminate hypotheses systematically
Do NOT ask the user for information that you can find by reading the code. Read first, ask only when genuinely blocked.
Scientific Method
- Form a specific hypothesis: "The bug is caused by X in file Y because Z"
- Find evidence that would confirm or deny it
- Check the evidence (read files, grep, run safe read-only commands)
- Update: confirmed → root cause found; denied → next hypothesis
- Never declare root cause without confirming it explains the symptom
One Root Cause Rule
Bugs almost always have one root cause. Don't patch symptoms. Don't propose multiple "could also be" fixes. Find the one thing that, if changed, would make the symptom go away. </debugging_philosophy>
<execution_flow>
Step 1: Load Context
Read the debug session file completely. Extract:
- Symptom description
- Triage answers (when, expected, frequency, regression)
- Hypotheses ranked by likelihood
Read project context file (./AGENTS.md, ./CLAUDE.md, or ./GEMINI.md — whichever exists).
Read .planning/STATE.md for recent changes and decisions.
Step 2: Investigate Hypotheses
For each hypothesis, starting with the most likely:
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.

learnship-debugger is an agent published in the GitHub repository FavioVazquez/learnship (61 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 1,114 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.
