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 | $0.01950 | $0.01950 |
| Opus 5.5 | $0.00780 | $0.00780 |
| Sonnet 5.5 | $0.00390 | $0.00390 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade A, and why
skill-memory-bank CLAUDE.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 9d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Key rules — project overrides
Global Key rules apply with these differences:
- Clean Architecture: Infra → App → Domain, never backward; Domain has 0 external deps
- English for everything written to the repo: code comments, commit messages, PR titles and descriptions; replies to the user stay in Russian (your rule)
- Replaces the global line:
architecture.
Details: .memory-bank/RULES.md.
Memory Bank Skill
Long-term project memory through .memory-bank/, engineering rules, SDD specs, executable /mb work tasks, verification, review, and session persistence.
Hard Rules
- Resolve the active Memory Bank before project work and say its state in your first reply.
- Existing bank →
[MEMORY BANK: ACTIVE]. - No bank →
[MEMORY BANK: ABSENT]; do not initialize unless explicitly requested.
- Existing bank →
- Read the project rules and Memory Bank context before implementation:
- global rules:
rules/RULES.mdfrom this skill bundle; - project overrides:
<repo>/AGENTS.md,<repo>/RULES.mdor<bank>/RULES.mdwhen present; - core context:
<bank>/status.md,checklist.md,roadmap.md,research.mdwhen present (the resolver also detects legacy-cased layouts).
- global rules:
- Size the task first (
references/effort-tiers.md, SKILL.md § Task routing). New logic at standard+ follows TDD — failing test first, then implementation, then verification; a small task gets one test per stated behavior; a trivial edit needs no new test. - Do not bypass an existing plan/spec. If work comes from Memory Bank, execute through
/mb workor the equivalent scripts. - If
.memory-bank/COORDINATION.mdexists, parallel sessions share the working tree: read the board withscripts/mb-coord.sh active(not the whole file) before stages, commits, and shared-file edits; scopedgit addonly (never-A); obey FREEZE entries. Protocol:references/coordination.md.
/mb work Gate
The gate applies when the task refers to an existing plan or spec in the bank (the user says implement, fix, continue, resume, next step, go by the plan, execute the spec, or similar about it). Without a plan or spec, route by tier — references/effort-tiers.md (SKILL.md § Task routing): trivial and small tasks are done inline. When the gate applies:
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.

skill-memory-bank CLAUDE.md is an instructions file published in the GitHub repository fockus/skill-memory-bank (31 stars, last pushed 9d ago), licensed MIT. It adds 1,950 tokens to every session, about $0.0078 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.
