Coder

The coder family is what makes OpenHuman a viable coding partner instead of a chat window that pretends to know the codebase.

Tools in the family

Tool	What it does
file_read	Read a file (with line numbers)
file_write	Write a new file
edit_file	Targeted edits - match-and-replace with strict uniqueness checks
apply_patch	Apply a unified diff
glob_search	Find files by glob pattern
grep	Ripgrep-style search across the tree
list_files	Walk a directory tree
read_diff	Diff between two files or revisions
git_operations	Status, diff, log, blame, branch, commit
run_linter	Run the project's linter
run_tests	Run the project's test command
csv_export	Export query results as CSV

Why these are native

• Edits go through uniqueness checks, so the agent can't accidentally clobber the wrong line
• Reads come back with line numbers the agent can refer to in follow-ups
• Git operations parse output into structured data
• Lint and test runs are wired to the project's actual commands

Workspace scoping

Filesystem tools respect a workspace boundary - the agent can't read or write outside it without explicit permission.
