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 5.1 | $0.00010 | $0.00520 |
| Opus 5.5 | $0.00004 | $0.00208 |
| Sonnet 5.5 | $0.00002 | $0.00104 |
| Haiku 4.5 | $0.00001 | $0.00052 |
Grade A, and why
with-std-lib scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to with-deno-stdlib — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Steps To Resolving Deno Lint Errors
Follow these step by step, and in the order they're shown until the issue is resolved:
- Check
deno.jsoncImports: import map shows installed libraries in format of"@std/fs": "jsr:@std/fs@1". If not installed,deno add {jsr:@std/fs@1}and import it with 'import { expandGlob } from 'std/fs@1'`. - Libraries in
@std/with/unstable-*in name have to be imported explicitly:
import { multiPromptSelect } from '@std/cli/unstable-prompt-select`
- NO imports from URLs or registry paths.
Deno addinstall instead and use the short name. Examples:
- GOOD:
import { parse } '@std/jsonc' - BAD:
import { parse } 'jsr:@std/jsonc' - GOOD:
import { ulid } '@std/ulid' - BAD:
import { ulid } 'jsr:@std/ulid' - GOOD:
import * as jose from 'jose' - BAD:
import * as jose from 'npm:jose'
- Use Deno Tools to Debug the Issue:
- LOCAL JSR package:
deno info --json | jq '.modules[] | select((.specifier | tostring) | test("^@std/cli$"))' - REMOTE JSR package:
deno info --json | jq '.modules[] | select((.specifier | tostring) | test("^(jsr:|https://jsr.io/)@std/cli"))' - LOCAL or REMOTE JSR package:
deno info --json | jq '.modules[] | select((.specifier | tostring) | test("(@std/cli|jsr:@std/cli|jsr.io/@std/cli)"))' - LOCAL Deno file:
deno info {example_name}.ts - LOCAL NPM package:
deno types npm:your-lib - UNKNOWN location of package: `deno info --json | jq '.modules[] | select((.specifier | tostring) | test('package alias'))'
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.

with-std-lib is a cursor rule published in the GitHub repository zackiles/cursor-mcp-manager (3 stars, last pushed 1y ago), licensed MIT. It adds 10 tokens to every session and 520 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to with-deno-stdlib, differing in 0 lines, and is treated as a copy.
