knowledge-base

A system for keeping long-term project knowledge between coding-agent sessions. The information is stored in a separate directory and can include project context, technical lessons, configurations, prompts, and references.

In plain words
What is it for?
It helps agents read previous project information before work and record useful technical or project knowledge afterward.
Why use it?
It prevents each new session from starting without important background information. Keeping the knowledge outside the code repository also avoids accidentally committing private context.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

knowledge-base 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 3d 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.

Knowledge Base Management Skill

Overview

The knowledge base is agentware's long-term memory across sessions. It does NOT live in this repo — it lives in an EXTERNAL directory the operator chose at onboarding. Resolve that directory at runtime:

KDIR="$(scripts/agentware config --knowledge-dir-only)"

It holds context about the user, their projects, technical learnings, and configurations. AI agents consult it before starting work and update it after completing work so future agents inherit the context. NEVER commit knowledge into this repo; it stays in $KDIR.

Directory layout (inside $KDIR)

$KDIR/
├── MAIN.md              # Active work entry point — read first; injected on every session
├── index.json           # Searchable metadata index (entries, tags)
├── FEATURES.md          # Generated table of contents (scripts/agentware features)
├── .initialized         # Sentinel written at the end of onboarding
├── learnings/           # Technical knowledge (one .md per topic)
├── projects/            # Active project context (one folder per project)
├── configurations/      # Service / environment configs
├── prompts/             # Reusable prompts
├── references/          # External references / pointers
├── skills/              # User/agent-created reusable procedures (category: skills)
├── templates/           # Entry templates installed at init (self-contained)
├── work/                # Per-feature plans/worklogs/state (<feature>/plan.md, .loop/)
└── logs/                # prompts.log + sessions/<id>/{main,full}.md + per-subagent transcripts

Everything mutable lives here. The orchestrator package stays read-only during normal use; only an explicit, !! WARNING !!-gated self-extension changes it.

scripts/agentware init scaffolds this. Onboarding seeds the first entries based on the interview; the loop adds to it over time.

index.json schema

Every entry is registered in $KDIR/index.json. Paths are stored RELATIVE to $KDIR so the index stays portable:

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.

knowledge-base is a skill published in the GitHub repository r5rana/agentware (24 stars, last pushed 16d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,153 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
