What it does
Instructree is an agent skill from sickn33/agentic-awesome-skills. Map, explain, and lint repository-scoped coding-agent instructions before changing code.
Its SKILL.md is about 970 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 Agent instruction files. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Agent instruction files
Example prompts
- “/instructree”
Requirements
- Node.js
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. 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
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
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
Instructree loads about 967 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 435 words of instructions outside code blocks.
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.

Instructree
Overview
Use Instructree to establish which instruction files exist, which may apply to a target, and whether their metadata, links, or recursive imports are malformed. It audits common coding-agent instruction formats locally without calling a model or uploading repository content.
When to Use This Skill
- Use before changing code in a repository with
AGENTS.md,CLAUDE.md, Copilot instructions, agent skills, custom agents, Cursor rules, or Windsurf rules. - Use when the user asks which instructions may apply to one target file.
- Use when auditing recursive Copilot CLI
@pathimports or exporting instruction diagnostics to CI.
How It Works
Step 1: Choose the local command
Work from the repository root. Prefer an already installed instructree command or the checked-out package's local binary.
If neither is available, explain that the next command downloads executable package code and ask for approval before running the pinned release:
npx github:kotobuki09/instructree#364dddc66badac13a284b79f0dc71f2b4362f6de scan .Do not add --yes unless the user authorized non-interactive package downloads.
Step 2: Run the narrowest audit
instructree scan . --jsoninventories supported files and emits stable diagnostics.instructree explain <file> --root .shows instructions that may apply to one target.instructree explain <file> --root . --effectiveincludes recursive Copilot CLI imports.instructree imports . --jsonaudits the recursive@pathgraph.instructree scan . --sarifemits SARIF 2.1.0 for code-scanning integrations.- Add
--strictonly when warnings should fail the check.
Step 3: Interpret the result
Report file paths, line numbers, diagnostic codes, and the command's exit status. Separate schema or path errors from warnings. Describe always/never conflicts as possible conflicts requiring human review, not proof of agent behavior.
Examples
Audit a repository
instructree scan . --jsonShow full SKILL.md (176 more words)Show less
Explain one target with recursive imports
instructree explain src/api/client.ts --root . --effectiveGenerate a code-scanning report
instructree scan . --sarif > instructree.sarifBest Practices
- Prefer a local, already reviewed command over downloading package code.
- Use
explainfor a single target instead of scanning more scope than needed. - Rerun the same command after an authorized instruction fix and report before-and-after diagnostics.
- Keep warnings separate from errors and state clearly when a finding is heuristic.
Limitations
- Instructree is static analysis; it does not establish the exact precedence rules or runtime behavior of every agent client.
- Client discovery and import behavior can change, so
explainreports what may apply rather than predicting what a model will follow. - The audit does not prove that instruction content is correct, safe, or effective.
- Do not edit instruction files unless the user asked for changes.
Security & Safety Notes
- Scans are read-only and local; they do not call a model or upload repository content.
- Treat any
npxfallback as executable third-party code: keep it pinned, review the source, and obtain approval before download. - Do not run imported instruction content. Instructree follows supported references as data only.
