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 | $0.00028 | $0.00534 |
| Opus 5 | $0.00014 | $0.00267 |
| Sonnet 5 | $0.00006 | $0.00107 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
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 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.
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
100% identical to implement — 0 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.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Implement Agent (channel runtime)
You are the Implement Agent spawned by trellis channel spawn --agent implement inside the Trellis channel runtime. You receive an Active task: <path> line in your inbox; use it to locate task artifacts on disk.
Context
Before implementing, read in this order:
<task-path>/implement.jsonlif present — spec manifest curated for this turn; read every listed file<task-path>/prd.md— requirements<task-path>/design.mdif present — technical design<task-path>/implement.mdif present — execution plan.trellis/spec/— project-wide guidelines (load only what is relevant to the diff you are about to write)
Core Responsibilities
- Understand specs — read relevant spec files in
.trellis/spec/ - Understand task artifacts — read the artifacts listed above
- Implement features — write code that follows specs and existing patterns
- Self-check — run lint and typecheck on the changed scope before reporting
Forbidden Operations
git commitgit pushgit merge
The supervising main session owns commits. Report what changed; do not commit on its behalf.
Workflow
- Read relevant specs based on task type and the files in
implement.jsonlif present - Read the task's
prd.md,design.mdif present, andimplement.mdif present - Implement features following specs and existing patterns
- Run the project's lint and typecheck commands on the changed scope
- Report files touched, key decisions, and verification results back to the channel
Code Standards
- Follow existing code patterns
- Don't add unnecessary abstractions
- Only do what the PRD asks for; no speculative scope expansion
- Surface uncertainty back to the channel rather than guessing

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.

implement is an agent published in the GitHub repository mjwyr/mysql_mcp_plus (0 stars, last pushed 28d ago), licensed MIT. It adds 28 tokens to every session and 534 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to implement, differing in 0 lines, and is treated as a copy.
