Harness patterns for coding agents — memory, permissions, context engineering, delegation, skills, hooks, bootstrap.

This skill should be used when agent work needs file-backed context: durable scratchpads, tool-output offloading, just-in-time discovery, cross-agent handoff files, filesystem memory, or cleanup…

guanyang/open-agent-hub

Persistent, token-efficient project memory. An agent skill from shobcoder/shob.

shobcoder/shob

Surgically select, compress, and recover codebase context using Entroly's MCP tools.

juyterman1000/entroly

Estimates the per-turn token cost of a project's .claude folder and CLAUDE.md, split into always-loaded, path-scoped and invoked-only files, and flags what runs over budget.

poshan0126/dotclaude

Keeps a long Claude Code task on-track — breaks out of looping/circular thinking, watches the context budget, bounds internal reasoning, and triggers a clean handoff before the window fills.

thananon/9arm-skills

Audits a project's Claude Code setup for common token-cost leaks and returns a prioritized fix list, using only static inspection of files and settings.

mergisi/awesome-openclaw-agents

Coder-agent working-file budget discipline: keep the editable working set (files you /add into writable context) under ~25k tokens, separate "read" from "edit", delegate breadth to a read-only…

agentsope/SkillAlchemy

Build batteries-included agents with planning, context management, subagent delegation, and sandboxed execution.

langchain-ai/docs

Prunes a bloated Claude Code session with the cozempic CLI using a gentle, standard or aggressive prescription, after a dry run and your confirmation.

Ruya-AI/cozempic

Sweep the current session for uncaptured durable knowledge, file it to disk, persist the open work records this session knows are unfiled or now wrong, and curate the home's tiered, decaying startup…

google-labs-code/jules-sdk

Arabic edition of a file-based planning skill that keeps task_plan.md, findings.md and progress.md on disk so multi-step agent work survives lost context.

OthmanAdi/planning-with-files

Analyze the token length of an OT-Agent conversation-format (ShareGPT-style) dataset — the per-trace distribution (median/p90/max) and/or counts under a token threshold + a metadata predicate (e.g.
