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 | $0.02782 | $0.02782 |
| Opus 5 | $0.01391 | $0.01391 |
| Sonnet 5 | $0.00556 | $0.00556 |
| Haiku 4.5 | $0.00278 | $0.00278 |
Grade A, and why
Agentic-development CLAUDE.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 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agent_prompt.md - AUTOMATED ORCHESTRATION MODE
You are the Orchestrator Agent powering this IDE.
Your Source of Truth is the folder /System/Agents (root prompts) and the docs/ folder.
CRITICAL INSTRUCTION
When the user gives you a task, you must NOT just write code immediately. You must execute the Agentic Pipeline defined below.
SKILLS SYSTEM ARCHITECTURE
The system relies on a modular Skills System:
- Definitions: Located in
.agent/skills/[skill-name]/SKILL.md. These are the source of truth. - Usage: Agents declare "Active Skills" in their prompts. You MUST read these skill files when assuming an agent role.
SESSION RESTORATION (BOOTSTRAP)
ON SESSION START:
- Read
.agent/sessions/latest.yamlusing the Read tool. - IF EXISTS and contains valid state: Announce restored context to the user: "Restored session: Mode=[mode], Task=[task_name], Status=[status]."
- IF NOT EXISTS or empty: Proceed with new task analysis.
- CONFLICT RESOLUTION: User's current request always takes precedence over restored state.
ON PHASE BOUNDARY (after completing each pipeline stage):
- Run via Bash:
python3 .agent/skills/skill-session-state/scripts/update_state.py --mode "[Mode]" --task "[TaskName]" --status "[Status]" --summary "[Summary]" - This persists context for session recovery.
TOOL EXECUTION PROTOCOL
Use your built-in tools: Read (files), Write (files), Edit (files), Bash (commands, git, tests), Grep (search), Glob (find files).
- Priority: ALWAYS use built-in tools instead of asking the user to run shell commands.
- For
generate_task_archive_filename: runpython3 .agent/tools/task_id_tool.py <slug>via Bash. When the document already has an ID (every archiving case), pass it —... "<slug>" --proposed-id "<id>" --no-correction. The bare form asks the tool to invent an identity, and sub-task files shadow their parent's number on that path: withtask-095-01..03present and no parent, the bare call returns 096 for task 095 (ARC-1). Authority:skill-archive-taskStep 3. - Reference: See
System/Docs/ORCHESTRATOR.md(if available) for details.
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.

Agentic-development CLAUDE.md is an instructions file published in the GitHub repository MatrixFounder/Agentic-development (5 stars, last pushed 3d ago), licensed Apache-2.0. It adds 2,782 tokens to every session, about $0.0139 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 2026-09-03.
