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 | $0.00840 | $0.00840 |
| Opus 5 | $0.00420 | $0.00420 |
| Sonnet 5 | $0.00168 | $0.00168 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
symbols 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 6d 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file is a compatibility guide for agents that look for CLAUDE.md.
AGENTS.md is the canonical engineering guide for this repository.
README.md is the canonical source for the public product surface: current
tools, resources, installation, and usage.
Read first:
- AGENTS.md
- README.md
- docs/MAINTENANCE.md for accepted follow-up work
- docs/PLUGIN_CONTROL_PLANE_DIRECTION.md
- docs/CODE_QUALITY_ROADMAP.md for the rationale behind the current TypeScript contracts
Repo Summary
Symbols is a lightweight MCP bridge to Language Servers.
It is intentionally small:
- skills and plugin assets carry installation and troubleshooting guidance
language-servers.yamlis the desired state- MCP resources expose effective config and runtime state
- MCP tools perform navigation, inspection, search, rename, diagnostics, and control-plane actions
Do not treat Symbols as:
- a managed installer framework
- a large MCP recipe catalog
- a broad workflow product with file, shell, or memory tooling
Engineering Preferences
- TypeScript and
pnpm; use the pinned toolchain (nvm use) - strict typing and build health matter
- prefer small modules, explicit data flow, and simple typed helpers
- prefer a pragmatic blend of functional and imperative style: pure helpers and plain transforms where they stay simple, stateful or imperative structures where they are the clearer fit (lifecycle, stores, plumbing)
- establish each fact once: coordinate base, URI conversion, normalization, and output limits each have one implementation
- earn abstractions: a little direct duplication beats a framework with hooks or branching flags
- keep comments that record constraints the type system cannot express; delete narration and changelog comments
Architecture Contracts
The flow is tools -> preparation -> operations -> session -> client.
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.

symbols CLAUDE.md is an instructions file published in the GitHub repository p1va/symbols (3 stars, last pushed 1mo ago), licensed MIT. It adds 840 tokens to every session, about $0.0042 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.
