The previous description (41 words) told the LLM to write 'complete AST
nodes' but did not explain that regex syntax is the #1 failure mode. It
also shipped a bug: the Python example 'def $FUNC($$$):' had a trailing
colon that the hint system actively flags as wrong.
Extract descriptions into tool-descriptions.ts and rewrite:
- Open with 'This is NOT regex' so the constraint is unmissable
- List the four regex patterns that do not work (|, .*, \\w, [a-z])
with the corrective action for each
- Tell the LLM to switch to grep when the pattern is text-shaped
- Fix the Python example (no trailing colon) and add Go and Rust rows
since the failing reports came from Go codebases
- Shorten the pattern-param description with the same anti-regex list
Also harden the LSP reference for the new test files using the
bun-types triple-slash directive already used elsewhere.
LLMs frequently call ast_grep_search with regex-style patterns like
'func.*build|BuildMode|projectReferences' instead of AST patterns. The
search silently returns zero matches with no useful feedback, so the
model retries with a different regex-shaped pattern and loops.
Extract hint generation into pattern-hints.ts and add detectors for the
four dominant misuse modes:
- regex escapes (\\w, \\d, \\s, \\b)
- character-class ranges ([a-z], [0-9])
- regex wildcards (.* .+) with no meta-vars
- pure alternation (foo|bar|baz with no structural syntax)
Heuristics are designed to be safe on valid AST patterns: bitwise OR
'$A | $B' and Rust closures '|x| x + 1' are not flagged. Language-
specific shape hints (trailing-colon Python, body-less JS/TS/Go/Rust
functions) are preserved and extended to Go and Rust.
Convert grep, glob, ast-grep, and session-manager tools from static exports to factory functions that receive PluginInput context. This allows them to use ctx.directory instead of process.cwd(), fixing issue #658 where tools search from wrong directory in OpenCode Desktop app.

- Show hints when Python class/function patterns return empty results
- Detect patterns ending with ':' that need body (class :, def ():)
- Removed validation that could cause false positives
- Hints only appear on empty results, not on successful matches
* fix(publish): make git operations idempotent
- Check for staged changes before commit
- Check if tag exists before creating
- Check if release exists before creating
* fix(ast-grep): add validation for incomplete function declaration patterns
- Add validatePatternForCli function to detect incomplete patterns like
'export async function $METHOD' (missing params and body)
- Only validates JS/TS languages (javascript, typescript, tsx)
- Provides helpful error message with correct pattern examples
- Update tool description to clarify complete AST nodes required
This fixes the issue where incomplete patterns would fail silently
with no results instead of providing actionable feedback.
- Add ast_grep_search for pattern-based code search (25 languages)
- Add ast_grep_replace for AST-aware code rewriting with dry-run
- Add ast_grep_analyze for in-memory code analysis (NAPI)
- Add ast_grep_transform for in-memory code transformation
- Add ast_grep_languages to list supported languages
