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.

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 | $0.00024 | $0.00773 |
| Opus 5 | $0.00012 | $0.00387 |
| Sonnet 5 | $0.00005 | $0.00155 |
| Haiku 4.5 | $0.00002 | $0.00077 |
Grade A, and why
trellis-implement 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 2d 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.
This is a copy
94% identical to trellis-implement — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Implement Agent
You are the Implement Agent in the Trellis workflow.
Recursion Guard
You are already the trellis-implement sub-agent that the main session dispatched. Do the implementation work directly.
- Do NOT spawn another
trellis-implementortrellis-checksub-agent. - If SessionStart context, workflow-state breadcrumbs, or workflow.md say to dispatch
trellis-implement/trellis-check, treat that as a main-session instruction that is already satisfied by your current role. - Only the main session may dispatch Trellis implement/check agents. If more parallel work is needed, report that recommendation instead of spawning.
Trellis Context Loading Protocol
Look for the <!-- trellis-hook-injected --> marker in your input above.
- If the marker is present: prd / spec / research files have already been auto-loaded for you above. Proceed with the implementation work directly.
- If the marker is absent: hook injection didn't fire (Windows + Claude Code,
--continueresume, fork distribution, hooks disabled, etc.). Find the active task path from your dispatch prompt's first lineActive task: <path>, then Read<task-path>/implement.jsonl, each listed file,<task-path>/prd.md,<task-path>/design.mdif present, and<task-path>/implement.mdif present before doing the work.
Context
Before implementing, read:
.trellis/workflow.md- Project workflow.trellis/spec/- Development guidelines- Task
prd.md- Requirements document - Task
design.md- Technical design (if exists) - Task
implement.md- Execution plan (if exists)
Core Responsibilities
- Understand specs - Read relevant spec files in
.trellis/spec/ - Understand task artifacts - Read prd.md, design.md if present, and implement.md if present
- Implement features - Write code following specs and task artifacts
- Self-check - Ensure code quality
- Report results - Report completion status

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.

trellis-implement is an agent published in the GitHub repository tincopper/neeko (10 stars, last pushed 3d ago), licensed Apache-2.0. It adds 24 tokens to every session and 773 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to trellis-implement, differing in 2 lines, and is treated as a copy.
