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 | $0.00570 | $0.00570 |
| Opus 5.5 | $0.00228 | $0.00228 |
| Sonnet 5.5 | $0.00114 | $0.00114 |
| Haiku 4.5 | $0.00057 | $0.00057 |
Grade A, and why
ai-agents 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 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.
What it actually says
Claude Code Instructions
@AGENTS.md
Claude Code Specifics
For non-trivial tasks, delegate to specialized agents via Task tool:
Task(subagent_type="orchestrator")by default for non-trivial workTask(subagent_type="Explore")for codebase exploration- Specialized agents (implementer, architect, analyst, etc.) for focused work
Installation Locations
| Type | Agents | Skills |
|---|---|---|
| Global | ~/.claude/agents/ |
~/.claude/skills/ |
| Per-repo | .claude/agents/ |
.claude/skills/ |
ADR-064 retired .claude/commands/. Skills are the single user-invocable
surface, and a blocking validator refuses a command file under any plugin root.
Path-scoped instructions
Before editing any file, read matching rules in .claude/rules/*.md; Claude Code reads that tree at runtime. Since ADR-109 B2 the edit location is templates/rules/<name>.md; uv run python build/scripts/build_all.py renders, mirrors, and binplaces it. A rule's paths frontmatter is the scope key; check_rule_scope_keys.py refuses any other. Universal rules live in universal.md.
The same run ships the Copilot copies under .github/instructions/ and src/copilot-cli/instructions/.
Skill routing
Explicit skill invocations still win: when the request names an available skill or uses that skill's slash command, invoke that skill first. Concrete requests that name no skill go through /autoplan below.
/autoplan is the canonical intent router for concrete requests that name no skill, per ADR-078. It routes to skills, lifecycle commands, and agent handoffs (for example orchestrator for multi-step work), not skills alone. Keep the routing table in .claude/skills/autoplan/SKILL.md; do not duplicate it here.
Explicit routing rules not owned by autoplan:
- Retro trigger → invoke retrospective skill
Lifecycle skills
Dev lifecycle phases. ADR-064 retired .claude/commands/, so these are skills
like every other user-invocable surface; /spec and the rest still type the same
because Claude Code fires a user-invocable skill by name:
- Define requirements, "what should we build" → spec
- Plan work, break down tasks, estimate → plan
- Implement, code, build features → build
- Test, prove it works, debug failures → test
- Review code, check my diff, architecture review → review
- Ship, deploy, push, create PR → ship
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.

ai-agents CLAUDE.md is an instructions file published in the GitHub repository rjmurillo/ai-agents (48 stars, last pushed today), licensed MIT. It adds 570 tokens to every session, about $0.0023 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 2026-09-03.
