What it does

Terrain Knowledge Skill is an agent skill from sopaco/deepwiki-rs. Use when a coding agent needs project knowledge from Terrain .terrain/ assets. Guides layered reading of context, private knowledge, and repomix index.

Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Codebase knowledge for agents. The repository describes itself as: Turn code into clarity. Generate accurate technical docs and AI-ready context in minutes—perfectly structured for human teams and intelligent agents. The licence is MIT.

When your agent uses it

  • A coding agent needs project knowledge from Terrain .terrain/ assets
  • Tasks that involve Codebase knowledge for agents

Example prompts

  • “/terrain-knowledge-skill”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Architecture — .terrain/agent/context.md
  2. Private domain — .terrain/knowledge/**/*.md
  3. Structured meta — .terrain/agent/meta-inputs.md
  4. Source index — see repomix-context-skill

What it can do on your machine

Read from SKILL.md and the folder at commit 27dbd3e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Terrain Knowledge Skill loads about 891 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~891

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

version
1.2.0

Terrain Knowledge Skill

Terrain stores AI knowledge assets under .terrain/ in this repository (not a global ~/.terrain/knowledge directory). The desktop app registry at ~/.terrain/registry.json only maps slugs → repo paths.

Load rtk-skill when you need to run shell commands during investigation (git, grep repomix file, tests). Resolve tools via conventional paths (~/.terrain/bin/…) with bunx/npx fallback — see rtk-skill / codegraph-skill.

Knowledge layers (mandatory order)

  1. Architecture — .terrain/agent/context.md

    • Module map, core flows, system boundaries, tech stack
    • Check .terrain/agent/context-meta.json or meta.json for asset timestamps
    • Read directly (short); no RTK needed

  2. Private domain — .terrain/knowledge/**/*.md

    • Business glossary, internal frameworks, APIs, scaffolding guides
    • Team-maintained markdown; read in filename sort order when surveying

  3. Structured meta — .terrain/agent/meta-inputs.md

    • Compiled from terrain-meta.json and knowledge/ scans

  4. Source index — see repomix-context-skill

    • Local .terrain/agent/repomix.md (gitignored; regenerate via Terrain scan)

Knowledge freshness (mandatory before architecture answers)

Before trusting context.md for module/architecture questions:

bash
~/.terrain/bin/terrain tools freshness --project <slug>
# or: bunx @terrain-ai/cli tools freshness --project <slug>

This recomputes when stale and writes .terrain/.meta/freshness.json. Do not only read that JSON statically — it is a local cache snapshot.

ScoreRule
< 50Do not rely on macro context; use repomix-context-skill
50–69Cross-check with repomix grep or codegraph-skill
≥ 70Architecture context is generally reliable

On conflict: repomix source slices > codegraph > agent/context.md > human/

For symbol impact/callers, also see codegraph-skill (CodeGraph status can lie; use terrain tools codegraph-drift).

Query workflow

Task received
  → freshness check (architecture tasks)
  → Read context.md (or relevant section)
  → If business/internal terms → read knowledge/*.md
  → If symbol / call graph → codegraph-skill
  → If implementation / source → repomix-context-skill
  → If shell/git/test needed → rtk-skill (prefix with rtk)

Rules

  • Do not invent module names that contradict context.md or meta-inputs.md
  • Do not read the entire live repository tree when indexed assets exist
  • Do not load full repomix.md into context — grep slices only (rtk grep on the file is OK)
  • Prefer .terrain/ over guessing project structure

Private knowledge directory

.terrain/knowledge/ — developers add markdown here; Terrain scans on context generation.

Example files:

  • 00-glossary.md — domain terms
  • 10-internal-framework.md — internal libs
  • 20-api-usage.md — internal APIs
  • 30-scaffolding.md — project generators

Human docs (optional)

.terrain/human/ — Litho-generated docs for humans; useful for onboarding context but denser than context.md.
