Add a /cache-probe slash command for debugging prompt caching behaviour
on OpenAI-compatible providers (GitHub Copilot, OpenAI direct).
The command sends two identical API requests in sequence and compares the
raw server response usage stats, showing:
- Input/output token counts
- Cache read tokens (from prompt_tokens_details or input_tokens_details)
- Latency for each request
- Cache hit rate percentage
Usage:
/cache-probe # test default model
/cache-probe claude-sonnet-4 # test specific model
/cache-probe gpt-5.4 --no-key # test without prompt_cache_key
The --no-key flag omits prompt_cache_key/prompt_cache_retention/store to
test whether the server does content-based auto-caching (it does on
GitHub Copilot).
This is a debugging/diagnostic tool, not intended for regular use. It was
instrumental in discovering that:
1. Copilot auto-caches server-side based on content hash
2. prompt_cache_key is ignored by the proxy
3. The streaming path was not reporting cached tokens
Only enabled when the provider is OpenAI or GitHub (not for firstParty
Anthropic which has different caching semantics).

* feat: add AutoFix config schema and reader module
Implements AutoFixConfigSchema (Zod v4) with validation for lint/test
commands, maxRetries (0-10, default 3), and timeout (1000-300000ms,
default 30000). Adds getAutoFixConfig helper that returns null for
disabled or invalid configs. All 9 unit tests pass.

* feat: add autoFix runner with lint/test command execution
Implements AutoFixRunner (Task 2) - executes lint and test shell commands
sequentially, short-circuits on lint failure, handles timeouts, and
produces structured AutoFixResult with AI-friendly error summaries.

* feat: add autoFix field to SettingsSchema with integration tests
Integrates AutoFixConfigSchema into SettingsSchema so autoFix settings
are validated at the settings layer. Adds two integration tests verifying
that valid configs are accepted and invalid configs (enabled with no
commands) are rejected.

* feat: add autoFix hook integration helpers (Task 4)
Implements shouldRunAutoFix and buildAutoFixContext functions used by
the PostToolUse hook to determine when to run auto-fix and format
errors as AI-readable context for injection.

* feat: wire autoFix into PostToolUse hook flow (Task 5)
Add auto-fix lint/test check after existing PostToolUse hooks in
runPostToolUseHooks. When autoFix is configured in settings, runs
lint/test commands after file_edit/file_write tools and yields
errors as hook_additional_context for the model to act on.

* feat: add /auto-fix slash command
Adds the /auto-fix prompt command that helps users configure autoFix settings
(lint/test commands, maxRetries, timeout) in .claude/settings.json.

* fix: address review feedback — enforce maxRetries, wire abort signal, use cross-platform shell
1. Enforce maxRetries: track auto-fix attempts per query chain in toolHooks.ts
and stop feeding errors back after the configured limit is reached.
2. Wire abort signal to subprocess: subscribe to AbortController signal in
runCommand() and kill the process tree on abort. Uses detached process
groups on Unix to ensure child processes are also terminated.
3. Replace hardcoded bash with shell:true: use Node's cross-platform shell
resolution instead of spawn('bash', ['-c', ...]) so auto-fix commands
work on Windows and non-bash environments.

This pass rewrites comment-only ANT-ONLY markers to neutral internal-only
language across the source tree without changing runtime strings, flags,
commands, or protocol identifiers. The goal is to lower obvious internal
prose leakage while keeping the diff mechanically safe and easy to review.
Constraint: Phase B is limited to comments/prose only; runtime strings and user-facing labels remain deferred
Rejected: Broad search-and-replace across strings and command descriptions | too risky for a prose-only pass
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Remaining ANT-ONLY hits are mostly runtime/user-facing strings and should be handled separately from comment cleanup
Tested: bun run build
Tested: bun run smoke
Tested: bun run verify:privacy
Tested: bun run test:provider
Tested: bun run test:provider-recommendation
Not-tested: Full repo typecheck (upstream baseline remains noisy)

* fix: disable experimental API betas by default to prevent 500 errors
Tool search (defer_loading), global cache scope, and context management
betas require internal Anthropic server-side support. External accounts
receive 500 Internal Server Error when these are sent.
Set CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=true by default in the CLI
entrypoint. Users with internal access can opt back in with =false.
Also includes: cache key stability fixes (Sonnet 1M latch, system-before-
messages key ordering, resume fingerprint isMeta skip), sideQuery default
cleanup, and /dream command.

* refactor: standardize API headers to Headers type and enable tengu feature flags by default
* fix: address PR review — dream lock, MCP betas guard, redundant Partial
- Call recordConsolidation() programmatically in /dream instead of
delegating to model prompt (unreliable)
- Add CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS guard to MCP entrypoint
(was only in CLI entrypoint, causing 500s in MCP server mode)
- Remove redundant ? markers from SecretValueSource Partial<{}> type

- Introduced environment variable CLAUDE_CODE_USE_GITHUB to enable GitHub Models.
- Added checks for GITHUB_TOKEN or GH_TOKEN for authentication.
- Updated base URL handling to include GitHub Models default.
- Enhanced provider detection and error handling for GitHub Models.
- Updated relevant functions and components to accommodate the new provider.
Squash the current repository state back into one baseline commit while
preserving the README reframing and repository contents.
Constraint: User explicitly requested a single squashed commit with subject "asdf"
Confidence: high
Scope-risk: broad
Reversibility: clean
Directive: This commit intentionally rewrites published history; coordinate before future force-pushes
Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr
Not-tested: Fresh clone verification after push
