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 | $0.02804 | $0.02804 |
| Opus 5 | $0.01402 | $0.01402 |
| Sonnet 5 | $0.00561 | $0.00561 |
| Haiku 4.5 | $0.00280 | $0.00280 |
Grade A, and why
claude_skills AGENTS.md 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 yesterday.
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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
8. **Bounded subprocess execution**: `scripts/run_bounded.py` runs a command with a timeout and terminates its full process group (POSIX process-group signals; `taskkill /T /F` on Windows) on expiry, including descendant How it starts

Evidence Proportionality
Before using tools, running tests, searching history, or gathering evidence, ask: Could the result materially change the decision, recommendation, or action? If not, skip that work; if uncertain, prefer the cheapest evidence that can resolve the uncertainty rather than maximizing information.
Repository Overview
Project: Claude Code Marketplace Plugin Collection — marketplace name jamie-bitflight-skills,
defined in .claude-plugin/marketplace.json. Most entries are local directories under plugins/.
The rest are external: the upstream astral plugin pinned by git-subdir, and
hallucination-detector from a sibling GitHub repo. Read the manifest for the current roster.
Purpose: Extends Claude Code CLI (and secondarily Codex, OpenCode, and GitHub's coding agent)
with specialized skills, commands, and agents for Python development, code quality, Git/CI-CD,
AI/LLM tools, documentation, and agent orchestration.
Languages: Markdown (skills/commands/agents), Python 3.11+ (scripts; .python-version pins 3.13),
JavaScript/TypeScript (hooks, MCP scripts)
Package Manager: uv (Astral) — all Python commands use uv run prefix
Python Version: 3.11+ required
The largest plugin is plugins/development-harness (install name dh) — the SAM 7-stage pipeline
with its own MCP servers (backlog_core/, sam_schema/), agents, and skills. It has its own
AGENTS.md; read it before working inside that directory.
Backlog backend for this checkout: GitHub Issues (.dh/config.yaml's backend.name: github).
This repo does not use Beads (bd) for task tracking. Never run bd init or bd setup at the
repo root. If a Beads integration block reappears in this file, delete it — it does not describe
this checkout. See plugins/development-harness/AGENTS.md's "Backend Providers" section for the
backend abstraction's Protocol architecture when extending or modifying dh's backend code.
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.

claude_skills AGENTS.md is an instructions file published in the GitHub repository Jamie-BitFlight/claude_skills (65 stars, last pushed today), licensed MIT. It adds 2,804 tokens to every session, about $0.0140 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
