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.

What it costs to keep this loaded
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 | $0.00036 | $0.01472 |
| Opus 5 | $0.00018 | $0.00736 |
| Sonnet 5 | $0.00007 | $0.00294 |
| Haiku 4.5 | $0.00004 | $0.00147 |
Grade A, and why
pi-lens-lsp-navigation 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 yesterday.
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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LSP Navigation and Diagnostics
Use lsp_navigation as PRIMARY for code intelligence. Use lens_diagnostics with source=lsp as PRIMARY for proactive type/error checks. Do NOT use grep/glob/ast-grep first for code intelligence.
Diagnostics
Use lens_diagnostics with source=lsp before builds/tests or after touching several files:
| Need | Tool call |
|---|---|
| Check one file | lens_diagnostics({ source: "lsp", scope: "paths", paths: ["src/file.ts"] }) |
| Check a folder | lens_diagnostics({ source: "lsp", scope: "workspace", path: "src/", severity: "error" }) |
| Check exact touched files | lens_diagnostics({ source: "lsp", scope: "paths", paths: ["src/a.ts", "src/b.ts"] }) |
| Slow server (Rust, Java) | lens_diagnostics({ source: "lsp", scope: "paths", paths: files, waitMs: 2000 }) |
| Include warnings | lens_diagnostics({ source: "lsp", scope: "paths", paths: files, severity: "all" }) |
Prefer explicit paths batches after multi-file edits — bounded concurrency, no unrelated directory noise.
Parameter reference
lens_diagnostics accepts source: "session" | "lsp" and scope: "paths" | "workspace". Use mode: "delta" for the current turn, "all" for the cache-only session view, or "full" for an active scan. path selects one file or directory; paths filters a batch. severity is "error", "warning", or "all"; serverScope is "primary" or "all".
For mode: "full", refreshRunners: "cached" | "cheap" | "all" | "none" (or false/true) controls project analyzers. The first three string modes can launch a fresh heavyweight analyzer pass, bounded by the slowest runner's roughly 180-second ceiling; none disables it. maxProjectFiles limits cheap project runners, maxLspFiles limits the LSP sweep, and includeGenerated: true includes generated-name paths. These three limits apply to full scans. concurrency and waitMs tune LSP batches.

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.

pi-lens-lsp-navigation is a skill published in the GitHub repository apmantza/pi-lens (403 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,472 once invoked, about $0.0002 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.
