corteza 0.6.2

CLI

The Live context indicator now reflects the actual size of the next prompt (system + tools + message history) rather than cumulative billed API tokens. Old behavior counted up forever — /clear and /compact had no visible effect on the indicator. Status line label updated from Usage to Live context.
/context now prints live usage and the auto-compact threshold alongside the loaded context files.
Auto-compact threshold raised from 80% to 90%. Pairs with the estimate above to avoid over-eager compaction now that the metric is more accurate.
Provider/model defaults centralized in resolve_provider_model(). Legacy kimi-k2 now resolves to kimi-k2.6 for moonshot. Moonshot’s chat temperature is forced to 1 (their API rejects other values on kimi).
Session field renamed: session$compactions -> session$compactionCount, matching memoryFlushCompactionCount. Existing on-disk sessions show 0 compactions until the next compact; display-only.

_read_prompt_via_bash now prints the prompt from R and captures input through a tempfile. Previously relied on bash -p plus system2(stdout = TRUE), which was fragile on terminals that mixed the prompt into stdout.

Relicensed from MIT to Apache License (>= 2) for explicit patent grant. Aligns with the rest of the cerebro toolchain (saber, pensar, hacer, cerebro). The LICENSE stub file is removed; Apache 2.0 R-package convention points to the system-installed template.

First CRAN submission.

Eight-phase refactor of the command-line interface so its subprocess no longer speaks MCP internally.

The CLI now drives a private callr::r_session worker. Tool dispatch goes through corteza::worker_dispatch() directly; no JSON-RPC, no tools/list handshake, no per-call envelope on the CLI-to-worker path.
serve() remains a spec-compliant MCP server for external clients (Claude Desktop, VS Code, mcptools). Public MCP behavior is unchanged.
New shared tool registry in R/registry.R. chat(), serve(), and the CLI all read from .skill_registry. No state duplication.
cli_worker_spawn(), worker_init(), worker_dispatch(), worker_tool_list(), cli_worker_drain_events() exposed with @keywords internal so the callr session can reach them as corteza::*.
Boundary-normalized errors: corteza_tool_error condition class carries tool name, args, original class, and message across the worker pipe.
Subagents (R/subagent.R) also use callr::r_session instead of spawning corteza::serve() children. Same architecture: one persistent worker per subagent, direct tool dispatch, no MCP.

New R/schema.R with schema_from_fn() and register_skill_from_fn(). Tool definitions are derived at runtime from formals() and the package’s .Rd files via tools::Rd_db(). Replaces 20+ hand-written skill_spec(params = list(...)) blocks with one-line registrations.
Type hints come from an R-style (type) parenthetical in @param docs ((character), (integer), (logical), (character vector), (character; one of: a, b, c) for enums).
schema_from_registry() produces the Anthropic-API-shaped tools payload the CLI sends to the model — in the CLI’s own process, not round-tripped through the worker.
inst/tinytest/test_tool_schemas.R asserts every formal maps to a @param entry and vice versa. Drift between doc and signature fails the test suite.

register_skill_from_fn() accepts an available predicate; schema_from_registry() filters tools whose predicate returns FALSE. Git tools gate on .git; web search gates on TAVILY_API_KEY. 18-20% fewer tokens in the system prompt for a bare environment.

tool_run_r() wraps non-scalar or over-threshold values with with_handle(). The LLM gets a str() summary plus an opaque .h_NNN handle instead of a flood of printed output.
New tool_read_handle(handle, op) for subsequent inspection (str, head, summary, print). Handles are addressable by name in later run_r calls.

Worker emits structured JSON events (tool_call, tool_result, timings) to stderr. CLI drains them between calls.
New --trace flag (and options(corteza.trace = TRUE)) pretty-prints the events inline via printify::print_step() / printify::print_message().
ANSI color detection: NO_COLOR honored, FORCE_COLOR overrides, classic Windows consoles fall back to plain text.

Windows tested against R 4.5.3 + Rtools45 + Git for Windows.
The shell tool resolves bash to an absolute path (Rtools first, Git Bash fallback) so C:\Windows\System32\bash.exe (the WSL launcher stub) cannot intercept commands.
Fallback cmd shell tool when no real bash is found.
Path validation uses normalizePath(winslash = "/") consistently.

Added: callr (for the worker transport), printify (for --trace rendering).
Kept: codetools, curl, jsonlite, llm.api, processx, saber.
Suggests: mx.api, tinytest.
