Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In @.claude/skills/add-rebase-rules/SKILL.md:
- Around line 59-79: The sed encoding table in SKILL.md is inaccurate:
rebase.sh's escape_litteral() only escapes \$, \[ and \], it does not escape &,
*, " or encode newlines/tabs; update SKILL.md or the script to make them
consistent. Fix options: 1) Update the Sed encoding section in SKILL.md to list
only the characters actually escaped by escape_litteral() (show that & and * are
not escaped and that newlines/tabs must be encoded earlier), and correct the
guidance about escaping `&` in sed replacement strings (advise using `\\&` in by
values); or 2) Modify rebase.sh's escape_litteral() to also escape `&`, `*`, `"`
and perform newline/tab encoding (and ensure tests/usage of apply_changes still
work). Reference rebase.sh and the escape_litteral() function and the sed
encoding table in SKILL.md when making the change.

In @.claude/skills/test-rebase-rules/run-all-tests.sh:
- Around line 215-243: The script currently silently ignores FILTER_FILES that
don't match any entry in MAPPINGS; modify the logic around MAPPINGS and the
for-loop that iterates over "${MAPPINGS[@]}" so that you track which
FILTER_FILES were matched (e.g., maintain a MATCHED_FILTERS set/array when you
set match=true for a given filter) and after the loop check for any FILTER_FILES
that were never matched; if any exist, print a clear error including the unknown
filter paths and exit non-zero (exit 1) so typos or stale paths fail fast.
Ensure the comparison remains the exact filename match used in the IFS='|' read
for file_path and do not change existing test_file invocation or the normal
successful flow when all filters are valid.

In @.claude/skills/test-rebase-rules/test-rebase-handler.sh:
- Around line 23-25: The wrapper currently evals the rebase handlers and then
blindly executes whatever is passed as "$@", which can run arbitrary binaries;
change the script to validate that there is at least one arg, ensure the first
argument is a sourced function by using declare -F "$1", and constrain "$1" to
the expected handler-name regex (e.g., the project's handler prefix pattern)
before dispatching; if the check fails, print an error and exit non‑zero,
otherwise call the handler with "$@" (this change affects the
test-rebase-handler.sh invocation logic around the eval and the subsequent "$@"
dispatch).

In `@rebase.sh`:
- Around line 16-17: The script rebase.sh currently hardcodes the upstream ref
when resolving the commit (uses "upstream-code/release/1.108") which breaks the
contract with PREVIOUS_UPSTREAM_VERSION and CURRENT_UPSTREAM_VERSION; update the
git rev-parse invocation to use the CURRENT_UPSTREAM_VERSION variable (e.g., git
rev-parse "upstream-code/${CURRENT_UPSTREAM_VERSION}") so the script honors the
configured CURRENT_UPSTREAM_VERSION variable and the skills' expectations.

Duplicate comments:
In @.claude/skills/fix-rebase-rules/SKILL.md:
- Around line 28-41: The skill currently fetches upstream files using
CURRENT_UPSTREAM_VERSION and PREVIOUS_UPSTREAM_VERSION extracted from rebase.sh,
but if rebase.sh still contains the hardcoded upstream version at line 582 the
skill will target the wrong release; first update rebase.sh to remove the
hardcoded version at that location so it uses the CURRENT_UPSTREAM_VERSION
variable, then ensure this skill uses those two variables
(CURRENT_UPSTREAM_VERSION and PREVIOUS_UPSTREAM_VERSION) when constructing git
show invocations (the logic referenced in the Step 1 text) so all file fetches
are validated against the intended upstream version.

In @.claude/skills/validate-rebase-rules/SKILL.md:
- Around line 19-34: The skill reads
CURRENT_UPSTREAM_VERSION/PREVIOUS_UPSTREAM_VERSION from rebase.sh but rebase.sh
still contains a hardcoded upstream ref that overrides it; edit rebase.sh to
remove the hardcoded ref and reference the parsed variable instead (use
CURRENT_UPSTREAM_VERSION where the hardcoded upstream-code/<version> is used),
ensure any git show/fetch invocations use
upstream-code/${CURRENT_UPSTREAM_VERSION}:<path> (and similarly use
PREVIOUS_UPSTREAM_VERSION where appropriate) so the validation and actual rebase
use the same version.

Nitpick comments:
In @.claude/skills/rebase/SKILL.md:
- Line 103: Several fenced code blocks in SKILL.md are missing language
specifiers (notably the blocks around lines referenced in the review); update
those triple-backtick fences to include the correct language identifiers (e.g.,
change ``` to ```bash or ```yaml as appropriate) so syntax highlighting works
for the code samples in .claude/skills/rebase/SKILL.md (ensure you update the
fences at the three reported locations).
