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 | $0.00344 | $0.00344 |
| Opus 5.5 | $0.00138 | $0.00138 |
| Sonnet 5.5 | $0.00069 | $0.00069 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
eai-gofer language-server.instructions.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 1mo 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
Language Server Development Instructions
You are working on the Gofer Language Server.
Architecture
The Language Server provides dual protocol support:
- LSP (Language Server Protocol) - Communication with VSCode extension
- MCP (Model Context Protocol) - Communication with AI assistants
Key Files
- Server Entry:
language-server/src/server.ts - MCP Tools:
language-server/src/mcp/toolHandler.ts - Spec Loader:
language-server/src/utils/goferLoader.ts
MCP Tools (6 Total)
| Tool | Purpose |
|---|---|
gofer_get_specs |
List all specs and tasks |
gofer_get_next_task |
Get next task based on dependencies |
gofer_execute_task |
Mark task in-progress, get context |
gofer_update_task_status |
Mark task completed/failed |
gofer_validate_code |
Check against constitution |
gofer_run_tests |
Execute Playwright tests |
Adding New MCP Tools
- Define tool in
server.tstool capabilities - Implement handler in
mcp/toolHandler.ts - Register in MCP tool list
- Test via Claude Code or Copilot
LSP Capabilities
- textDocument/completion - Spec suggestions
- textDocument/hover - Spec details
- Custom methods for spec operations
Dependencies
- vscode-languageserver 9.0.1
- Static validation service (no direct model SDK/API key dependency)
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.
