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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 37 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- high System Prompt Leakage · line 93 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
- medium Agent Snooping · line 118 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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 | $0.00058 | $0.03028 |
| Opus 5.5 | $0.00023 | $0.01211 |
| Sonnet 5.5 | $0.00012 | $0.00606 |
| Haiku 4.5 | $0.00006 | $0.00303 |
Grade A, and why
setup scanned grade A with 1 finding 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 15d 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.
Asks the agent to reveal its instructionslowSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
1. **Clean up what you don't need.** If your server has no prompts, delete the echo prompt and its registration in `src/index.ts`. Same for resources, or the app-tool pair if you're not targeting UI-capable clients. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
This skill assumes bunx @cyanheads/mcp-ts-core init [name] has already run. The CLI created the project's CLAUDE.md and AGENTS.md for different agents, copied external skills to framework-skills/, and scaffolded the directory structure with echo definitions as starting points. This skill covers what was created and what to do next.
Agent Protocol File
The init CLI generates both CLAUDE.md and AGENTS.md with identical content — CLAUDE.md is read by Claude Code, AGENTS.md by Codex, Cursor, Windsurf, and other agents. Keep both. Shipping both keeps the project agent-agnostic, and they're cheap to hold in sync: edit one, then cp CLAUDE.md AGENTS.md (the framework keeps its own pair byte-identical the same way, enforced by check-docs-sync). Only delete one if you're certain the project will never be opened by the other family of agents.
For the full framework docs, read node_modules/@cyanheads/mcp-ts-core/CLAUDE.md (or its identical twin AGENTS.md) once per session. It contains the exports catalog, tool/resource/prompt contracts, error codes, context API, and common import patterns.

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.

setup is a skill published in the GitHub repository cyanheads/obsidian-mcp-server (698 stars, last pushed 15d ago), licensed Apache-2.0. It adds 58 tokens to every session and 3,028 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
pkm-session-end
Use when wrapping up a work session — creates devlog entry, captures undocumented decisions/research/debugging, audits link health of session work, and updates project index. Primarily used via the pkm-capture agent.
pkm-write
Use when writing to the vault — creating new notes (vaultwrite), editing existing notes (vaultedit, vaultappend, vaultupdatefrontmatter). Handles duplicate checking, link discovery, annotations, and index updates for new notes. Provides guidelines for modifications.
pkm-explore
Use when researching what the vault knows about a topic — performs graph + semantic exploration with gap analysis to map existing knowledge and find missing connections. Primarily used via the vault-explorer agent. Not for routine session-start context loading (hooks handle that).
triage-tasks
Use when you want to review and batch-update open vault task statuses for the current project or across all projects.
tackle-task
Use when starting work on a specific vault task, when a task title or path is mentioned, or when coming from triage output.
add-task
Use when you want to quickly capture a new task in the vault from a title, with optional priority and due date.
