ground-claim

ground-claim is a skill for Claude Code from griffinwork40/agent-afk. It costs 87 tokens per session (1,540 once invoked), scanned A, original, Apache-2.0.

A capability-checking method that traces claims back to files and, when needed, to actual runtime connections. Runtime wiring means checking where code is registered and executed.

In plain words
What is it for?
Use it to verify what a project or add-on supports, or to confirm whether specific middleware, plugins, agents, or other features are registered and used.
Why use it?
It helps distinguish a feature that exists in files from one that is actually connected and active in the running system.

Token cost

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.

Security

Grade A, and why

ground-claim 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 8d 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 — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Trigger

Mode: capability (default) — Self-referential meta-capability questions about the current repository, framework, or system:

  • "What does this repo enable?"
  • "What are the orchestration patterns available?"
  • "List the available skills."
  • "What capabilities does the plugin provide?"

Mode: runtime-wiring — Claims that require tracing actual execution paths, not static structure:

  • "Verify that middleware Y intercepts all requests."
  • "Confirm plugin Z is loaded on startup."
  • "Validate that feature X is active in production."

Skip both modes for: usage questions ("how do I use X?"), bug reports, feature requests.


Mode: capability (default)

Procedure

  1. Extract capability nouns. From the user's question, identify 2–5 concrete capability categories (e.g., skills, hooks, agents, orchestration patterns, CLI commands, verification methods). Write them down.

  2. Locate and read evidence. For each capability noun:

    • Use Glob or Grep to locate source files (e.g., skills/*/SKILL.md for skills, hooks/ for hooks, agents/ for agents).
    • Read at least one concrete source file per capability. Record the file path and specific line numbers.
    • Do not rely on training data, model recall, or session-listing attachments. Evidence must come from Read tool output.
  3. Build the answer inline. Embed citations within claims, not in a separate appendix. Format: path/to/file.md:line—<claim context>.

  4. Tag ungrounded claims. If a capability claim cannot be traced to a file read, prefix it with [UNVERIFIED: what would be needed to verify this]. Never present an unverified claim without the tag.

  5. Declare sources read. Explicitly name which files you read in the response.

Hard rules

  • Do not answer from model recall alone.
  • Do not answer from session-listing attachments without reading the underlying SKILL.md or manifest files.
  • Every capability claim must point to a source. Do not summarize without citation.
  • Do not bury unverified claims. Use the [UNVERIFIED] prefix and state the evidence gap.
  • At least one path:line citation per named capability.

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.
