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 | $0.00050 | $0.00635 |
| Opus 5 | $0.00025 | $0.00318 |
| Sonnet 5 | $0.00010 | $0.00127 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
skill-creator 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 4d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Creator
Contract
This skill guarantees:
- New skill follows conformance standard (frontmatter + required sections)
- MECE check: no overlap with existing skills' triggers
- Frontmatter
triggers:route the intended phrases - New skill shows up in
list_skills - Skill passes the conformance audit (
memex skillpack check)
Phases
- Identify the gap. What capability is missing? What user intent has no skill?
- MECE check. Enumerate the installed skills with
list_skillsand read their frontmattertriggers:viaget_skill. Does any existing skill already cover this? If so, extend it instead of creating a new one. - Create SKILL.md. Use this template:
---
name: {skill-name}
version: 1.0.0
description: |
{One paragraph describing what the skill does and when to use it.}
triggers:
- "{trigger phrase 1}"
- "{trigger phrase 2}"
tools:
- {tool1}
- {tool2}
mutating: {true|false}

## Tools Used
{MCP tools used, with descriptions}
- Write the routing. The frontmatter
triggers:array IS the routing — phrase each entry the way a user would actually say it. There is no separate routing file to update. - Confirm discovery.
list_skillsshould return the new slug, andget_skill {name}should return the file you just wrote. - Verify. Run
memex skillpack checkto confirm the new skill passes conformance.
Output Format
New skills/{name}/SKILL.md file, discoverable via list_skills with
triggers that route.
Anti-Patterns
- Creating a skill that overlaps with an existing one (violates MECE)
- Skipping the MECE check against existing skills
- Creating a skill without triggers in frontmatter
- Shipping a skill that never shows up in
list_skills - Creating a skill without an Anti-Patterns section
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.

skill-creator is a skill published in the GitHub repository timurgaleev/memex (8 stars, last pushed 2d ago), licensed MIT. It adds 50 tokens to every session and 635 once invoked, about $0.0003 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.

design-mcp-server
Design the tool surface, resources, and service layer for a new MCP server. Use when starting a new server, planning a major feature expansion, or when the user describes a domain/API they want to expose via MCP. Produces a design doc at docs/design.md that drives implementation.
api-context
Canonical reference for the unified Context object passed to every tool and resource handler in @cyanheads/mcp-ts-core. Covers the full interface, its RequestContext base, all sub-APIs (ctx.log, ctx.state, ctx.requestInput, ctx.inputs, ctx.enrich, ctx.content), and when to use each.
api-canvas
DataCanvas primitive reference — a Tier 3 SQL/analytical workspace for tabular MCP servers, backed by DuckDB. Use when registering tables from upstream APIs, running ad-hoc SQL across them, and exporting results. Covers the acquire → register → query → export flow, per-table TTL, the token-sharing pattern for…
api-testing
Testing patterns for MCP tool/resource handlers using createMockContext and Vitest. Covers mock context options, handler testing, McpError assertions, format testing, Vitest config setup, and test isolation conventions.
field-test
Exercise tools, resources, and prompts against a live HTTP server via MCP JSON-RPC over curl. Starts the server, surfaces the catalog, runs real and adversarial inputs, and produces a tight report with concrete findings and numbered follow-up options. Use after adding or modifying definitions, or when the user asks to…
api-config
Reference for core and server configuration in @cyanheads/mcp-ts-core. Covers env var tables with defaults, priority order, server-specific Zod schema pattern, and Workers lazy-parsing requirement.
