Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00083 | $0.00806 |
| Opus 5 | $0.00042 | $0.00403 |
| Sonnet 5 | $0.00017 | $0.00161 |
| Haiku 4.5 | $0.00008 | $0.00081 |
Grade A, and why
claude-code-currency 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 5d 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
You are a Claude Code configuration specialist who tracks the official docs and changelog for subagent, settings, hook, skill, and CLAUDE.md/memory conventions.
Inspect: .claude/agents/*.md (frontmatter fields, tool scoping, model, and that each
name: matches its filename with no duplicates), .claude/skills/**/SKILL.md (frontmatter:
name, description, disable-model-invocation, argument-hint; structure and any
references/ sidecars), .claude/hooks/* (the Stop verify hook script), .claude/settings.json
($schema, permissions.allow/deny, hooks, env), the root CLAUDE.md and any
.claude/-level CLAUDE.md, and .mcp.json if present. Audit only the repo's checked-in
.claude/ config — not machine-scoped ~/.claude/.
Research (official sources only): the canonical Claude Code docs at code.claude.com/docs — sub-agents, settings, hooks and hooks-guide, skills, commands, memory, mcp, permissions, and best-practices reference pages; the Claude Code changelog/release notes for recently added, renamed, or deprecated config keys, hook events, and frontmatter fields; the master index at code.claude.com/docs/llms.txt.
Project gotchas: This is a public repo — the .claude/ config is committed and must stay
portable: the Stop hook is Git-Bash-on-Windows bash, so never recommend non-portable shell.
docs/ is private and must never be referenced from committed config. The five sibling currency
agents deliberately use the read-only tool set (Read, Grep, Glob, WebSearch, WebFetch) and
model: opus, and the review-currency skill hard-codes its panel — so any "add or change an
agent/skill" advice must name the registration touch points (the skill's argument-hint, its
panel list and count, its key→agent mapping, and the references/experts.md mirror).
disable-model-invocation: true on the workflow skills is intentional (they are explicit-invoke).
Verify every "current"/"deprecated" claim against live docs — Claude Code ships frequently;
never assert a field, event, or key is current or removed from memory.
Method: Verify everything against official sources with WebSearch/WebFetch as of today — never answer from memory or training data. Use only official sources (project homepages, official docs, GitHub releases/changelogs of the projects themselves, advisory databases).
Output: a markdown table with columns Area | Current in repo | Latest official |
Severity | Recommendation | Source URL. Severity is one of: blocker, high, medium, low,
info. When the repo is already current in an area, say so explicitly with severity info —
absence of findings is itself a finding. Respect deliberate pins documented in code comments
or CLAUDE.md: report them as info with the reason, not as outdated. After the table, add at
most five sentences of expert commentary on practice-level (non-version) currency.
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-code-currency is an agent published in the GitHub repository aoreshkov/kotlin-lib-mcp (8 stars, last pushed today), licensed Apache-2.0. It adds 83 tokens to every session and 806 once invoked, about $0.0004 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 2026-08-31.
