Conversation
Copilot CLI discovers SKILL.md skills from .github/skills/, .agents/skills/, .claude/skills/, ~/.copilot/skills/ and ~/.agents/skills/, and custom agents from .github/agents/. ECC's existing skill and agent frontmatter is already compatible, so the README's 'no native skill discovery' and 'no subagent API' statements are out of date. Because ECC ships a Codex skill subset in .agents/skills/, a plain clone already loads 42 ECC skills into Copilot CLI with no configuration. Placing skills/ at .github/skills/ loads all 286, all enabled. Documentation only. No installer target, no hook porting, no new execution surface. Verified against Copilot CLI 1.0.83.
The jq snippet filtered on source == "project", which returns 290 rather than 286: the full catalog under .github/skills/ plus the .claude/commands/ entries and the one .agents/skills/ skill whose name does not collide with a full-catalog entry. Filter on the path instead and explain the de-duplication. Also document that Copilot registers a skill under its SKILL.md frontmatter name rather than its directory name, so catalog folders whose directory and frontmatter names differ still load.

Copilot CLI 1.0.83 lists all 42 plain-clone entries under Project skills with source project and enabled true. Record that the three from .claude/commands/ are Claude command files surfaced as skills, and that their reported path is the .claude/commands directory rather than a per-skill subdirectory.

Reviewers without the CLI on PATH can reproduce the plain-clone count with the npm-distributed build. The 39 + 3 split is reported by 1.0.82 from npm and by 1.0.83 installed locally, so it is not specific to one build or install method. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
GitHub Copilot CLI discovers SKILL.md skills from .github/skills/ and custom agents from .github/agents/, so ECC's catalog can be installed there without a conversion step. This adds a managed-project install target that places both. Scope is deliberately limited to agents and skills. ECC hooks are written against Claude Code's event model, and commands rely on slash-command argument substitution Copilot does not provide, so neither is installed. Agent frontmatter goes through an allowlist transform rather than a passthrough: Copilot resolves the session model from user configuration, so a Claude model id makes it warn and fall back on every invocation; Claude tool names are not Copilot tool names, and Copilot governs tool access per session via --allow-tool/--deny-tool. Unknown keys added to ECC agents later therefore cannot leak into the Copilot copy. Target selection stays permissive in supportsModule so dependency-anchor modules still resolve; planOperations is what narrows the install, matching the convention used by the other adapters.

In `@README.md`:
- Line 1907: Update the README manual copy commands near the skills and agents
setup examples to create the destination directories and copy the contents of
skills/. and agents/. into them, avoiding nested skills/skills or agents/agents
paths when destinations already exist.
- Around line 1874-1876: Update the README guidance near the agent frontmatter
compatibility statement to clarify that only name and description are
compatible; instruct users to use the copilot target for conversion so
Claude-only fields such as model, tools, and color are removed.
In `@scripts/lib/install-targets/copilot-project.js`:
- Line 20: Update supportsCopilotSourcePath() to reject normalized paths
containing any .. traversal segment before performing prefix matching, so
planOperations() produces zero operations for paths such as
agents/../../escape.md. Add a regression test covering this input and asserting
zero planned operations.

Learning: In this repository, standalone JavaScript test suites under tests/lib/ follow a local runner convention: they use mutable `passed`/`failed` counters and print per-test console output. During code reviews, treat this as the expected harness style and generally avoid recommending one-off refactors to immutable counters for new/modified suites. Only request such counter refactors if the repository-wide test harness/convention is being changed.

Learning: JavaScript tests under tests/ should emit a summary containing parseable tokens in the form `Passed: N` and `Failed: N`. The `tests/run-all.js` aggregator parses these tokens from combined stdout and stderr, so a combined line such as `Results: Passed: N, Failed: N` is sufficient; do not require separate `Passed: N` and `Failed: N` lines.

Document the required agent conversion.
This says that no conversion is needed, but the Copilot adapter removes model, tools, and color. Manual copies can therefore retain Claude-only fields and produce the warnings documented later in this section. State that only name and description are compatible, or tell users to use the copilot target for conversion.
The local adapter contract confirms this discrepancy.

Copy directory contents into the destination.
If .github/skills or .github/agents already exists, these commands create nested paths such as .github/skills/skills and .github/agents/agents. The documented copilot target creates these directories, so rerunning the manual commands can produce the wrong layout. Create the destinations and copy skills/. and agents/. into them.
The documented target paths make existing destinations a normal case.

Reject traversal segments during planning.
supportsCopilotSourcePath() accepts agents/../../escape.md, so planOperations() emits a destination outside .github. applyInstallPlan() later rejects that destination, but the invalid operation can still abort installation. Reject .. segments before prefix matching and add a regression test that expects zero operations.

When a project already has a custom skill or agent at an ECC destination, the standard Copilot installation writes the managed file without checking ownership, causing the project-authored content to be lost.
Artifacts
Disposable Copilot ownership-conflict validation script
- Creates a temporary project with a user-authored conflicting agent, invokes the real non-dry-run Node Copilot installer, and asserts the before/after ownership condition; takeaway: the test directly exercises the claimed collision path.
Project-authored agent before Copilot installation
- Captured output of the fixture preparation command shows the conflicting agent's unique user sentinel, its digest, and absence of ECC install state; takeaway: the destination was unambiguously project-authored before installation.
Project-authored agent after non-dry-run Copilot installation
- Captured output of the real Copilot installer run shows `dryRun: false`, `applied: true`, replacement ECC content, an absent user sentinel, and written install state; takeaway: the installer overwrote the existing project-authored file.

**Managed writes overwrite user files**
When a project already has a custom skill or agent at an ECC destination, the standard Copilot installation writes the managed file without checking ownership, causing the project-authored content to be lost.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
…limit AGENTS.md requires functions under 50 lines; planOperations was 54 and mixed source filtering, destination mapping, and operation construction. Extract the per-path mapping into planSourcePathOperations and share the prefix test with supportsCopilotSourcePath. planOperations is now 18 lines. No behaviour change.

Issue 2 — planner exceeds size limit: valid, fixed in
Issue 1 — managed writes overwrite user files: accurate, but pre-existing and repo-wide rather than introduced here. I reproduced it, then ran the identical experiment against the existing Same silent replacement, no warning, no ownership check. The cause is the shared write path — So this affects Happy to open a separate issue with the antigravity reproduction if that's useful. One caveat worth recording either way: |

Corroborating the shared-behaviour point with the ownership-recording detail, since that is the more serious half of the finding. I ran the same experiment against the existing {

}The project-authored file was overwritten and claimed as managed with a digest — identical to the Copilot behaviour described above, including the ownership record. The practical consequence is worse than a lost edit: a later uninstall would remove a file ECC never created, because install-state now asserts ownership of it. For completeness, the Copilot reproduction on my side: Same shape, different adapter. This is why I would rather not fix this in one adapter and leave the same latent data loss in the other eleven. Two options, whichever you prefer:
Happy either way; the scope call is yours. |

Summary
Adds a
copilotinstall target that places ECC's skill and agent catalog where GitHub Copilot CLI discovers it: skills to.github/skills/, agents to.github/agents/.Stacked on #2960 — that PR corrects the README's Copilot support claims, this one makes the placement automatic. The docs commits appear here until #2960 merges; the reviewable change is the last commit.
Scope
Deliberately limited to agents and skills:
Nothing is written outside
.github/.Agent frontmatter transform
Agent files go through an allowlist (
name,description) rather than a passthrough, because the remaining Claude keys do not transfer:modeltools--allow-tool/--deny-tool, so carrying the list asserts a restriction Copilot does not apply.colorAn allowlist rather than a denylist means keys added to ECC agents later cannot silently leak into the Copilot copy.
The warning this eliminates, observed directly:
Implementation note
supportsModulestays permissive andplanOperationsdoes the narrowing. Filtering insupportsModuleinstead looks tidier but breaks dependency resolution: modules that act purely as dependency anchors (rules-core,commands-core,platform-configs) get skipped, and every module depending on them goes with it. An unsupported path now contributes zero operations rather than removing the module. This matches the convention the other adapters use.Verification

npm testonmainate04ea0b: 3972 tests, 3941 passed, 31 failed. This branch adds 13 tests and 13 passes, with no change in the failure count. Two files differed between the two full runs (lib/install-state-projection,integration/plan-canvas-e2e); running each in isolation on both refs gives identical results (8/0 and 8/1 respectively), so both are pre-existing or flaky under full-run contention rather than caused by this change.npm run lintcould not be executed locally — the corporate npm proxy 404s onignore@7.0.8and the public registry is TLS-intercepted.
