Summary
This PR fixes a critical bug in
file_tools._handle_file_edit()where theencodingparameter was being ignored, causing file operations to use the platform's default encoding instead of the explicitly specified encoding. This could lead to data corruption or encoding errors when working with files that require specific character encodings (e.g., UTF-8, Latin-1, etc.).Key improvements:
encodingparameter is now properly read from inputs and passed to both file read and write operationsencodingfield for proper validationChanges

[AUTO-EPIC] Epic Linkage
This issue is a child of Epic #8082 — A2A Facade Session & Guard Enforcement (M6) (v3.5.0).
The file edit encoding fix is part of the tool execution infrastructure that the A2A facade depends on.
Dependency direction: This issue (#8258) BLOCKS Epic #8082.

Hi team,
Thanks for tackling the encoding bug. The implementation looks good, but a few gating requirements from CONTRIBUTING.md are still outstanding:

Implementation Attempt — Tier 1: haiku — ✅ Success
What Was Fixed
Two issues were identified and resolved in this PR:
1. Duplicate Function Definition (Critical Bug)
File:
features/steps/tool_builtins_steps.pyA bare (undecorated) duplicate of
step_when_file_edit_with_encoding()existed at lines 148–160. In Python, this second definition silently overwrote the first, orphaning the@when(...)decorator from the actual function body. This would cause the Behave stepI edit file "edit-enc.txt" replacing ... specifying encoding ...to fail at runtime with a step-not-found error.Fix: Removed the duplicate bare function definition (15 lines deleted).
2. Missing CHANGELOG Entry

Because UTF-8 is already the default on our CI runners, this scenario passes even on the pre-fix implementation and therefore does not protect the regression.

Thank you for the implementation work on this encoding fix. CI is now green ✅ and the core logic change in

encodingwas ignored). It is therefore not a regression guard — it provides no protection against the bug re-appearing.Required fix: Use a non-default encoding such as
latin-1with non-ASCII content (e.g.café) so the test fails without the fix and passes with it. The implementation comment #205879 described exactly this change (latin-1 withcafé → naïve) but it was never pushed to the branch — the diff still showsutf-8.❌ Issue 2 — CONTRIBUTORS.md not updated

Code Review: REQUEST CHANGES
Thank you for the implementation work on this encoding parameter fix. The core logic changes are sound, CI is fully green ✅, and the approach of threading the
encodingparameter throughread_text()andwrite_text()is correct. However, two critical issues from the previous official review (review #5772) remain unresolved on the current HEAD.❌ Issue 1 — Encoding BDD scenario does not exercise the bug (critical)
File:
features/tool_builtins.featureThe new scenario
Edit file uses explicit encoding parametercreates a file with UTF-8 encoding and edits it withencoding "utf-8":Why this is a problem: UTF-8 is the platform default on our Linux CI runners. This scenario passes even on the pre-fix implementation (where the
encodingparameter was ignored). It therefore provides zero regression protection — the test cannot fail without the fix.Edge-case analysis: The boundary condition you need to test is: "What happens when the file's actual encoding differs from the platform default?" The current test doesn't cross that boundary.
Required fix: Use a non-default encoding with non-ASCII content:
latin-1encoding with a non-ASCII character (e.g.,café)latin-1encodingExample:
This ensures the test exercises the actual bug: if
encodingis ignored, the file read/write will fail or produce corrupted output when using non-default encodings.❌ Issue 2 — CONTRIBUTORS.md not updated
