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 | $0.00870 | $0.00870 |
| Opus 5.5 | $0.00348 | $0.00348 |
| Sonnet 5.5 | $0.00174 | $0.00174 |
| Haiku 4.5 | $0.00087 | $0.00087 |
Grade A, and why
forgetful AGENTS.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 3d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Forgetful Development Guide
Contributions
Before opening issues or pull requests, read the contributor guide's AI tool guidance and submission policy.
Architecture
Before changing code or reasoning about this repository's architecture, read the architecture overview.
Consult the detailed class map only as needed, using the overview's reading advisories. Do not load the entire map into context by default.
After major code changes, check whether the architecture diagram or explanations are still accurate and update them if needed. Small changes do not require diagram regeneration. Preserve reviewed explanations that remain accurate. Keep the overview at most 500 lines; it has no column-width limit, including Mermaid statements.
Mycelium is optional tooling, not a prerequisite for contributing or updating the overview.
Its architecture skill and map-generation skill
are available in ScottRBK/mycelium if useful. If refreshing the generated backup,
use fresh analysis, keep the JSON outside the repository, and export full detail with
--max-classes 1000, --test-path tests, and --test-path test_harness/runs.
Layered architecture: routes -> services -> protocols -> repositories/adapters No pollution of service layer with integration/implementation details
Run uv run pytest tests/architecture/ to check and prove the agreed import boundaries.
Testing Philosophy
We focus on integration and E2E tests over unit tests. Tests should cover critical workflows without exhaustive edge case coverage.
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.

forgetful AGENTS.md is an instructions file published in the GitHub repository ScottRBK/forgetful (340 stars, last pushed 4d ago), licensed MIT. It adds 870 tokens to every session, about $0.0035 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.
