What is deep-init copilot-instructions.md?

Repository instructions for deep-init that give coding agents context about Kemal, a Sinatra-style web framework for the Crystal programming language. They describe its middleware pipeline, global DSL, project components and reference documentation.

Use them when working on the Kemal codebase, especially its request handlers, configuration, lifecycle, DSL or related components.

They reduce the need to rediscover the framework’s architecture and important project rules before changing code.

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	$0.01688	$0.01688
Opus 5.5	$0.00675	$0.00675
Sonnet 5.5	$0.00338	$0.00338

Security

Grade A, and why

deep-init copilot-instructions.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 1mo 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.

Repository instructions (Copilot projection)

Canonical context lives in AGENTS.md + .ai/docs/ — this file is a generated projection of the lean tier; do not edit inside the DeepInit markers (regenerated each run).

kemal — Agent Context

Kemal is a lean, Sinatra-style HTTP web framework for the Crystal language: a global-scope DSL (get "/" {... }, ws, sse, before_all, use, mount) layered over a fixed HTTP::Handler middleware chain that a single process-wide Config singleton assembles and owns.

Architecture

A composable HTTP::Handler middleware pipeline driven by a Sinatra-style global DSL over a process-global Config singleton. The whole src/kemal/ tree is loaded by three glob requires in src/kemal.cr; files reference siblings by fully-qualified constants, not per-file imports. Components map to .ai/docs/components/.

Components (7)

core — entry point + global run/stop lifecycle + the Config singleton that assembles the ordered handler chain + the top-level DSL + CLI/SSL. → .ai/docs/components/core.md
handlers — the HTTP::Handler middleware links (init, exception, head, override-method, path, static-file, filter) + the base handler with only/exclude matching. → .ai/docs/components/handlers.md
router — route storage/matching/dispatch: the terminal RouteHandler + LRU route cache, the modular Router DSL, and param parsing with body-size guards. → .ai/docs/components/router.md
websocket — real-time transports: WebSocketHandler (Origin allow-list), the WS route wrapper, and Server-Sent Events. → .ai/docs/components/websocket.md
helpers — global view/response helpers, ECR templating macros, the exception hierarchy, and path/zip utilities. → .ai/docs/components/helpers.md
logging — pluggable request-logging abstraction (deprecated in favor of stdlib Log); the default RequestLogHandler + legacy/no-op loggers. → .ai/docs/components/logging.md
ext — stdlib monkey-patches (NOT under Kemal::): reopens HTTP::Server::Context (params/redirect/route lookup + typed @store) and HTTP::Server::Response. → .ai/docs/components/ext.md

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.
