What is king-context AGENTS.md?

Repository instructions for king-context, a local-first command-line retrieval tool for AI agents. It indexes information into files and provides commands for searching, reading, scraping documentation, and researching the web.

Use them when developing king-context, its command-line tools, Python packages, documentation-scraping pipeline, web-research pipeline, or related server code.

They explain the project's purpose, required language rules, preferred command-line workflow, and which parts are current versus legacy. This gives agents the context needed to make compatible changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01886	$0.01886
Opus 5.5	$0.00754	$0.00754
Sonnet 5.5	$0.00377	$0.00377

Security

Grade A, and why

king-context AGENTS.md 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Instructions for AI agents working in the king-context repository. This file is the canonical, tool-neutral rule set. CLAUDE.md imports it and adds Claude-Code-specific guidance on top. Do not duplicate content between the two.

What this project is

King Context is a CLI-first, local-first retrieval layer for AI agents. It indexes any corpus (vendor docs, web research, architecture decisions) into a flat-file store under .king-context/ and serves it through three console scripts: kctx (search and read), king-scrape (documentation scraping pipeline), and king-research (web research pipeline). It ships as the npm installer @king-context/cli plus a Python package with four sub-packages: king_context, context_cli, llm_providers, scraper_providers.

The MCP server (king-context-server) still ships but is the legacy, secondary surface per ADR-0001. Do not frame the project, its docs, or new features around MCP.

Non-negotiable rules

All code, comments, identifiers, documentation, commits, and PR descriptions are written in English.
Never use em-dashes or en-dashes anywhere: code, comments, docs, READMEs, commits, PR bodies, issues. Use periods, commas, colons, or parentheses instead.
Never mix languages in the same file. Internal architecture drafts in .docs/ may be Portuguese; everything else is English. README-pt-br.md is the one intentionally Portuguese published file.
ADRs are created and updated only through the kctx adr CLI: draft the markdown elsewhere, import with kctx adr new --from-file, then run kctx adr index and kctx adr validate. Never hand-write or hand-edit files inside .king-context/adr/.

The two retrieval stacks (critical orientation)

The repo contains two parallel retrieval stacks that do not share data:

Canonical: the CLI flat-file stack. src/context_cli/ reads and writes JSON under .king-context/docs/, .king-context/research/, and .king-context/decisions/. Search is reverse-index metadata scoring. No SQLite, no embeddings.
Legacy: the MCP SQLite stack. src/king_context/server.py (FastMCP) plus db.py (SQLite, FTS5, embedding rerank) with docs.db and data/ at the repo root. Kept as an integration layer per ADR-0001.

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.
