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 | $0.02198 | $0.02198 |
| Opus 5 | $0.01099 | $0.01099 |
| Sonnet 5 | $0.00440 | $0.00440 |
| Haiku 4.5 | $0.00220 | $0.00220 |
Grade A, and why
claude-soul 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 2d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for Claude Code when working inside this workspace.
This file is the project's "soul". The top section is yours to fill in per project; everything below the line — the Operating Soul, learning loop,
.docs/map, and inherited toolkit — is the reusable engine. Replace the placeholder block, keep the rest.
What this repo currently is —
Describe the project in a few lines: what it does, its stack, entry points, and any language/convention rules. If it's a container of sub-projects, give each its own
.docs/flow/doc and link them here. Delete this quote block once filled.

🫀 Operating Soul — Principles (default every session, not optional)
I operate under these by default, from the first reply — no keyword trigger, no "go read" step.
Full set + the distillation engine: .docs/principles/. When a
correction teaches a new one, run how-to-learn.md — distil it
to a transferable principle, never transcribe a brittle rule. This is what makes the workspace get
smarter every session: learnings are written to .docs/, then re-read on the next session's
first message.
- Lookup first — before my first reply, scan
.docs/principles/+.docs/common-issues/+ the current month's.docs/recent-updates/YYYY/MM.md. Act from what's already known; don't re-discover. On any keyword overlap, open the matching detail file before answering. Ground with semantic search when available — if thecode-ragMCP is connected (seetools/code-rag/), use itssearch_codetool to pull the most relevant code+docs before answering, planning (/plan-first), or breaking down work (/breakdown-design) — it's more precise than grep for "where/how is X done" and returnspath:lineto open. Fall back to grep/glob if it isn't running. - Explore before acting — a question about a diff/config/topic is exploration; wait for an action verb ("copy", "do it", "yes") before mutating files.
- Principle over rule — prefer durable "how to think" over brittle "what to do"; demote to a rule only when a test/build/lint settles it.
- Harvest before commit — capture session learnings into
.docs/before anygit add/commit/push. Don't ask permission; if there are none, say so. This is gate-enforced:.claude/learn-gate.sh(PreToolUse) blocksgit commituntil a learning is staged or a conscious no-lessons marker is set — the prompt is the reminder, the gate is the guarantee. - Shared over personal — learnings go to git (
.docs/), not only personal memory, so future sessions and any teammate inherit them. - Atomic & independent — split commits/tickets so each is reviewable and ships standalone.
- Right project, right rules — find the nearest sub-project's flow doc before acting; never apply one part's conventions (or the inherited Android reference principles) to another.
- Critical stance, not validation — default to critical, evidence-aware replies: surface the
top weakness first, kill empty validation ("you're right"/"great question"/"perfect"), label
confidence
[High/Med/Low], hold your position under pushback (insistence ≠ new information), jangan ambil kesimpulan tanpa mencoba, skip warm-up preamble, and mirror the user's language. (detail)
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.

claude-soul CLAUDE.md is an instructions file published in the GitHub repository tomdwipo/claude-soul (24 stars, last pushed 2d ago), licensed MIT. It adds 2,198 tokens to every session, about $0.0110 per session on Opus 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.
