What is trellis-meta?

A guide to the Trellis files and settings that control a project's workflow, agents, commands, memory, and collaboration tools. Trellis is a local development system that adds these controls inside a project.

Customizing project workflows, platform hooks, agent definitions, skills, prompts, settings, channel behavior, and stored session memory.

It helps developers understand where the system is configured and how to change its generated behavior safely.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00110	$0.02881
Opus 5.5	$0.00044	$0.01152
Sonnet 5.5	$0.00022	$0.00576

Security

Grade A, and why

trellis-meta 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 1mo 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.

Trellis Meta

This skill is for local Trellis users who have already run trellis init in a project. After reading it, an AI should understand the Trellis architecture, operating model, and customization entry points inside that user project, then modify the generated .trellis/ and platform directory files according to the user's request.

Trellis v0.6 adds three architectural surfaces on top of the pre-v0.6 workflow / persistence / platform model. First, a multi-agent collaboration runtime: trellis channel coordinates multiple AI worker processes through project-scoped JSONL event logs at ~/.trellis/channels/<project>/<channel>/events.jsonl, with worker OOM guard, forum/thread channels, durable idempotency keys, and bundled .trellis/agents/{check,implement}.md runtime definitions. Second, cross-session memory: trellis mem list | search | context | extract | projects reads raw Claude Code, Codex, and Pi Agent JSONL already on disk, slices by --phase brainstorm|implement|all, and never uploads anything. Third, a dual-package npm release: @mindfoldhq/trellis (CLI) and @mindfoldhq/trellis-core (SDK with /channel, /task, /mem, /testing subpaths) ship in lockstep on one version. Treat these as first-class customization surfaces alongside the per-platform integration files.

The default operating scope is local files in the user project:

.trellis/: workflow, config, tasks, spec, workspace, scripts, bundled runtime agents, and runtime state.
Platform directories: .claude/, .codex/, .cursor/, .opencode/, .kiro/, .gemini/, .qoder/, .codebuddy/, .github/, .factory/, .pi/, .reasonix/, .kilocode/, .agent/, .devin/, .kimi-code/, and similar directories. Pi additionally exposes a native trellis_subagent tool with single / parallel / chain dispatch modes, throttled progress cards, and isTrellisAgent() validation on top of the file layout. Reasonix stores both workflow skills and subagent skills as .reasonix/skills/<name>/SKILL.md; subagent skills carry runAs: subagent frontmatter. Kimi Code keeps workflow skills in the shared .agents/skills/ layer and delivers commands plus agent prompts as .kimi-code/skills/<name>/SKILL.md.
Shared skill layer: .agents/skills/.
User-owned channel store outside the project tree: ~/.trellis/channels/<project>/<channel>/events.jsonl.
Raw platform conversation logs queryable via trellis mem: ~/.claude/projects/, ~/.codex/sessions/, and ~/.pi/agent/sessions/ (OpenCode adapter degraded for the v0.6 line).

Do not assume the user has the Trellis source repository. Do not default to modifying the global npm install directory or node_modules — both @mindfoldhq/trellis and @mindfoldhq/trellis-core ship as published packages sharing one version and one git tag per release.

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.
