trellis-implement

A coding agent that turns specifications and requirements into code changes. It does not create Git commits.

In plain words
What is it for?
Use it to build requested features and apply code changes based on a project specification.
Why use it?
It handles implementation work while leaving the commit decision and commit creation to you or another workflow step.

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.

Made for: Claude Code.

Per session 24 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 773 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin unknown No closer match found in the catalogue.
Token cost

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.

Security

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 3d 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 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 mindfold-ai/Trellis (14,378 stars, last pushed 6d ago), licensed AGPL-3.0. 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. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

capsule-regenerator

Regenerates a recalled Feature Capsule onto the CURRENT codebase. Given a regeneration brief (the capsule's intent/knobs/data-assumptions/resurrection guide + the live source of the regions it touches), it re-implements the feature into today's code — adapting to refactors — and leaves a reviewable diff. It never runs…

Two jobs: (1) confirm or reject candidate dependson edges that the deterministic engine over-produced from name overlap; (2) classify each baseline overlaps pair (capsules touching the same code region) into a more precise relationship.
