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.

Model	Per session	Once invoked
Fable 5.1	$0.00201	$0.00201
Opus 5.5	$0.00080	$0.00080
Sonnet 5.5	$0.00040	$0.00040
Haiku 4.5	$0.00020	$0.00020

Security

Grade A, and why

claude-code-plugin AGENTS.md 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 2mo 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.

What it actually says

AGENTS.md

pmndrs/claude-code-plugin — a Claude Code plugin published as the pmndrs plugin from the pmndrs marketplace.

Generalist: nothing here is scoped to a single pmndrs library. A component that only helps one repo belongs in that repo, not here.

Agent skills

Issue tracker

Issues live as GitHub issues in pmndrs/claude-code-plugin, via the gh CLI. External PRs are not a triage surface. See docs/agents/issue-tracker.md.

Triage labels

Default vocabulary — each role's label string equals its name. See docs/agents/triage-labels.md.

Domain docs

Single-context: one CONTEXT.md and one docs/adr/ at the repo root. See docs/agents/domain.md.

Changes

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.
