agtx is a terminal-based shared workspace where multiple coding agents coordinate through a task board. Developers use it to delegate work, run agents in parallel across git worktrees, and move tasks through different workflow phases.
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.

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 | $0.00041 | $0.00419 |
| Opus 5 | $0.00020 | $0.00210 |
| Sonnet 5 | $0.00008 | $0.00084 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade A, and why
agtx-plan 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 11d 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
Planning Phase
You are in the planning phase of an agtx-managed task.
Input
The argument to this command is a task ID. Fetch the task description using the agtx MCP tool:
mcp__agtx__get_task(task_id: "<the id passed to this command>")
Use the description field as the task to work on. Also check for .agtx/research.md if a research phase was completed first.
Instructions
- Fetch the task description via
get_task - If
.agtx/research.mdexists, read it for prior analysis - Explore the codebase to understand relevant files, patterns, and architecture
- Identify all files that need to be created or modified
- Create a detailed implementation plan
Output
Write your plan to .agtx/plan.md in the current working directory (do NOT navigate up — write directly to .agtx/plan.md relative to where you are now) with these sections:
Analysis
What you found in the codebase — relevant files, patterns, dependencies.
Plan
Step-by-step implementation plan — files to modify, approach, order of changes.
Risks
What could go wrong — edge cases, breaking changes, areas needing extra care.
CRITICAL: Stop After Writing
After writing .agtx/plan.md (in the current working directory):
- Do NOT start implementing
- Do NOT modify any source files
- Say: "Plan written to
.agtx/plan.md. Waiting for approval." - Wait for explicit instructions to proceed
Output Style
Terse. No pleasantries. Fragments OK. Short synonyms. Code exact. Status updates: one line. Pattern: [what] [why]. Done.
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.

agtx-plan is a skill published in the GitHub repository fynnfluegge/agtx (1,503 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 419 once invoked, about $0.0002 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 2026-08-30.
