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 | $0.00022 | $0.01581 |
| Opus 5.5 | $0.00009 | $0.00632 |
| Sonnet 5.5 | $0.00004 | $0.00316 |
| Haiku 4.5 | $0.00002 | $0.00158 |
Grade A, and why
observability 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 2mo 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.

Observability Skill
Maintain transparent, human-readable logs of AI decision-making process.
Workspace Mode Note
When running in workspace mode, log to .aha-loop/logs/ai-thoughts.md instead of logs/ai-thoughts.md.
The orchestrator will provide the actual paths in the prompt context.
The Job
- Log significant thoughts and decisions to
logs/ai-thoughts.md - Provide visibility into AI reasoning process
- Create anchors for humans to understand what's happening
- Never hide failures or uncertainty
When to Log
Always Log
- Starting a new task - What am I about to do and why
- Major decisions - When choosing between approaches
- Unexpected findings - Something surprising or important
- Errors and recovery - What went wrong and how I'm handling it
- Completion - What was accomplished
Optional Log (Detailed Level)
- Intermediate steps
- Research findings
- Minor decisions
- Progress updates
Log Format
Append to logs/ai-thoughts.md:
## 2026-01-29 14:30:00 | Task: PRD-003 | Phase: Research
### Context
I'm researching authentication strategies for the web app. This is critical
because it affects security architecture and user experience.
### Inner Thoughts
The vision mentions "simple" and "quick to use". Traditional username/password
might add friction. Considering passwordless options but need to evaluate
complexity tradeoffs.
### Decision Point
- Considering: Traditional email/password
- Considering: Magic link (passwordless)
- Considering: OAuth only (Google/GitHub)
- **Chosen:** Magic link with OAuth fallback
- **Reason:** Aligns with "simple" goal, reduces password fatigue,
OAuth provides familiar alternative
### Current Progress
- [x] Read vision requirements
- [x] Research auth options
- [ ] Prototype magic link flow
- [ ] Evaluate email service options
### Observations
- Magic link requires reliable email delivery
- Need to consider rate limiting to prevent abuse
- Session duration is important for UX
### Next Action
Will research email service providers (Resend, SendGrid) and evaluate
their free tiers since budget constraint mentioned "no paid APIs".

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.

observability is a skill published in the GitHub repository YougLin-dev/Aha-Loop (178 stars, last pushed 9mo ago), licensed MIT. It adds 22 tokens to every session and 1,581 once invoked, about $0.0001 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.
