What it does
Agent Context Loader is an agent skill from jeremylongshore/tons-of-skills-marketplace. Execute proactive auto-loading: automatically detects and loads agents.md files. Use when appropriate context detected. Trigger with relevant phrases based on skill purpose.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `references/errors.md`). Compatibility notes: Designed for Claude Code
It sits in Agent Workflows, covering Codebase knowledge for agents and Agent instruction files. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Appropriate context detected
- With relevant phrases based on skill purpose
Example prompts
- “/agent-context-loader”
Requirements
- A Bash shell
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(general:*), Bash(util:*)
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Scan the current working directory and all ancestor directories (up to the filesystem root or repository root) for files named AGENTS.md…
- Search subdirectories of the current workspace for additional AGENTS.md files that may apply to sub-projects or modules.
- Determine load order: files closer to the repository root load first (global context), files in deeper directories load later (override or…
- Read each discovered AGENTS.md file and extract its instruction blocks, workflow definitions, and constraint declarations.
- Merge instructions into a unified context, noting any conflicts between levels (e.g., a subdirectory agent overriding a root-level rule).
- Present the loaded context as a structured summary: source file path, instruction count, and any detected conflicts.
- Cache the discovery results for the current session to avoid redundant filesystem scans on subsequent activations.
What it can do on your machine
Read from SKILL.md and the folder at commit 80f86df. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGrepGlobBash(general:*)Bash(util:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Shell), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
agents.mdcode.claude.com
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.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
Agent Context Loader loads about 1.1k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 500 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); the scripts in this folder are not scanned.

Agent Context Loader
Overview
Automatic discovery and loading of AGENTS.md files across project hierarchies for AI coding agents. This skill scans the current workspace and its parent directories to locate agent instruction files, then surfaces their contents so the active agent session has full operational context.
Prerequisites
- A project workspace containing one or more
AGENTS.mdfiles at any directory depth - Read and Glob permissions to traverse the directory tree
- Grep access for searching file contents when multiple candidates exist
Instructions
- Scan the current working directory and all ancestor directories (up to the filesystem root or repository root) for files named
AGENTS.mdoragents.md. - Search subdirectories of the current workspace for additional
AGENTS.mdfiles that may apply to sub-projects or modules. - Determine load order: files closer to the repository root load first (global context), files in deeper directories load later (override or supplement).
- Read each discovered
AGENTS.mdfile and extract its instruction blocks, workflow definitions, and constraint declarations. - Merge instructions into a unified context, noting any conflicts between levels (e.g., a subdirectory agent overriding a root-level rule).
- Present the loaded context as a structured summary: source file path, instruction count, and any detected conflicts.
- Cache the discovery results for the current session to avoid redundant filesystem scans on subsequent activations.
Output
- Ordered list of discovered
AGENTS.mdfile paths with their directory depth - Merged instruction set combining all discovered agent contexts
- Conflict report highlighting any contradictory directives between levels
- Session cache status indicating whether results are fresh or reused

Error Handling
| Error | Cause | Solution |
|---|---|---|
No AGENTS.md found | Workspace has no agent instruction files | Confirm the correct working directory; create an AGENTS.md at the project root if needed |
| Permission denied on directory traversal | Restricted parent directories above the workspace | Limit scan depth to the repository root (detected via .git/ presence) |
| Circular symlink detected | Symlinked directories create an infinite traversal loop | Skip symlinked directories during the scan; log a warning with the symlink path |
| Conflicting instructions across levels | A subdirectory AGENTS.md contradicts the root-level file | Flag the conflict in the output; apply the more specific (deeper) instruction by default |
| File encoding error | AGENTS.md uses a non-UTF-8 encoding | Attempt latin-1 fallback; report the file path and encoding issue |
Examples
Example 1: Monorepo with per-package agent instructions
- Structure: Root
AGENTS.mdsets global conventions;packages/api/AGENTS.mdadds API-specific tooling rules. - Result: Both files loaded in order. The API-specific rules supplement the global context without conflict.
Example 2: Nested workspace with conflicting commit policies
- Structure: Root
AGENTS.mdsays "always sign commits";services/legacy/AGENTS.mdsays "skip commit signing." - Result: Conflict detected and reported. The deeper (legacy) directive is applied with a warning noting the override.
Example 3: First-time setup with no agent files
- Structure: A freshly cloned repository with no
AGENTS.mdanywhere. - Result: Scan completes with zero files found. Output includes a suggestion to create
AGENTS.mdat the repository root with a minimal template.
