Add fleet-gitops-export skill (live Fleet to fleetctl new GitOps repo) - #57037
Adds fleet-gitops-export, an agent skill that turns a live Fleet instance into a ready-to-use GitOps repo laid out exactly the way fleetctl new scaffolds it. It's meant to replace fleetctl generate-gitops, which exports the right data in a different layout. generate-gitops is unchanged.
What it does (.claude/skills/fleet-gitops-export/):
Preflight: checks that fleetctl has new, that it's logged in as a global admin, the server URL and version, the tier, MDM status, GitOps-mode exceptions, and that the target directory is empty. When fleetctl isn't set up, each FAIL names the missing step (install fleetctl, set the Fleet address, log in to Fleet, reach Fleet) with the exact command. The agent installs fleetctl (after asking) and sets the address itself; the user logs in in their own terminal, so a password or API token never passes through the agent.
Scaffold: runs fleetctl new, then scans its output (fleet templates, paths: globs, platforms/<os>/<kind>/ folders). Every destination is derived from that scan, not hardcoded, so the export picks up whatever scaffold the user's fleetctl ships.
Export: reads Fleet through fleetctl api, GET only, on an allowlist of the endpoints generate-gitops uses. The skill never sees the API token. It writes a reviewable placement plan that holds no secret values.
Place: fills default.yml and the fleet files in place, keeping the templates' comments. Commented-out examples become real settings where Fleet has them, and example data Fleet doesn't have is deleted. It writes .env.example, a README section, and the workflow env: entries.
Validate: runs the scaffold's own fleet-gitops validator (scaffolded from fleetctl 4.95.0; skipped with older versions), parses the YAML, checks references and orphans, reconciles the repo against Fleet item by item and field by field (content hashes for scripts, profiles, and DDM assets), and runs fleetctl gitops --dry-run --delete-other-fleets. Reconcile fails on any settings key it doesn't compare and on a $VARIABLE that isn't where the plan put it, and validate fails if a secret value it fetched turns up in any repo file. Secret values go only into that process's environment. Values Fleet can't return (FLEET_SECRET_* variables, masked tokens) come from the exported repo's gitignored .env (or --env-file), which the user fills in themselves, so they never pass through the agent.
Report: what was exported per fleet, gaps, variables to set, and the rerun command.
The design choices worth reviewing are in references/mapping.md:
Shared platform folders: a fleet keeps a template glob only when it matches exactly that fleet's files.
Identical items are written once.
Unassigned's controls go in default.yml, because fleetctl accepts controls in only one of default.yml and unassigned.yml. When an Unassigned policy uses run_script or resend_configuration_profile, they go in unassigned.yml instead, because fleetctl checks those policies against that file's own controls.
Literal $ is escaped as \$. fleetctl expands $VAR in YAML and profiles, and generate-gitops doesn't escape it.
An enroll secret inside a profile or DDM asset (Fleet stores profiles after fleetctl expanded them) is written back as that secret's variable. The collector records only where it appears, never the value.
Fleet-maintained app scripts are written only when an admin changed them. Fleet tracks that (install_script_edited, uninstall_script_edited) but the API doesn't return it yet, so a stored script that's close to the catalog's current one is treated as an older copy of Fleet's script, left out, and listed for review; --keep-fma-scripts keeps named ones. The skill uses the flags once the API returns them.
Custom packages leave out Fleet's default install and uninstall scripts (matched against copies of pkg/file/scripts, kept in sync by a test), and don't pin hash_sha256 when the URL doesn't name a version; policies reference those packages by package_path.
references/parity-checklist.md compares the two item by item, and references/secrets.md lists every secret.
Guides: the skill's README.md is a step-by-step guide from installing fleetctl to turning on GitOps in CI. articles/export-fleet-to-gitops-with-an-ai-agent.md is a shorter version for fleetdm.com/guides.
Cross-agent:SKILL.md follows the Agent Skills format with an agent-neutral body, and the scripts are stdlib Python 3.9+ that call only fleetctl. .agents/skills/fleet-gitops-export/SKILL.md is a pointer so Codex, Cursor, Copilot, Gemini CLI, and Kilo Code discover it in this repo. This mirrors the fleetctl new template's .agents/.claude arrangement, the other way around. The body avoids Claude-only syntax such as $ARGUMENTS, and the frontmatter has a compatibility field. SKILL.md also covers long-running commands, sandboxes without network access, runs with no one to answer questions, and Windows (py -3). In Claude Code, allowed-tools pre-approves only the skill's own script (via ${CLAUDE_SKILL_DIR}), not every python3 command. A test that runs inside this repo fails if the pointer's frontmatter drifts from SKILL.md.
Found along the way (not fixed here):
fleetctl rejects the documented org_settings.yara_rules[].path form as an unknown key, and the inline form fails at apply ("rule entry missing path"). YARA rules can't currently round-trip through GitOps.
In .github/fleet-gitops/gitops.sh, the template's commented FLEET_SSO_METADATA line reads FLEET_MDM_SSO_METADATA. The export fixes the copy it writes.
personal-mobile-devices.yml in the template has examples pointing at ../lib/ios/..., but the folder is platforms/ios/.
The dry run prints "for new fleet" for existing fleets too: both branches print the same message.
fleetctl from main (4.95.0) always sends enable_profile_validation (server/service/client.go), so it can't run fleetctl gitops against a 4.94.0 server.
The fleet-gitops validator that fleetctl new scaffolds from 4.95.0 flags SQLite's json_each and names defined in a query's WITH clause as unknown osquery tables, and reports each finding once per fleet that references the file.
generate-gitops has the same Fleet-maintained app problem: it compares stored scripts with the current catalog's and pins every older copy as a custom script.
Checklist for submitter
Timeouts are implemented and retries are limited to avoid infinite loops
Testing
Added/updated automated tests: python3 -m unittest discover -s .claude/skills/fleet-gitops-export/scripts/tests (96 tests, offline; passing on Python 3.9.6 and 3.15). They cover $-escaping against a port of fleetctl's expansion, YAML quoting, the read-only guards, path containment, the private work folder, the .env reader and which dry-run values it supplies (including the quoted mask), clear failures when an earlier step's work files are missing, preflight's setup messages, the .agents pointer staying in sync, enroll-secret spans and variables, Fleet-maintained app script classification, default package script matching (and the copies staying in sync with pkg/file/scripts), unpinned hashes and package_path, .deb/.rpm naming, script platform hints, and an end-to-end plan, placement, and reconcile on the real fleetctl new templates, including a feature-rich synthetic Fleet (Apple Business, VPP, EULAs, SSO, setup experience, App Store apps, Android certificates) that has to reconcile with no findings.
QA'd all new/changed functionality manually. On a local throwaway Fleet (Premium dev license, Apple and Windows MDM with self-signed certs), with three fleets plus Unassigned and fixtures covering:
labels of all three kinds, plus fleet labels;
policies with run_script, install_software, resend_configuration_profile, and a patch policy;
reports, scripts with name collisions, a script package, a URL package with custom scripts, and a Fleet-maintained app;
Apple, iOS, and Windows profiles, a DDM declaration with a custom activation, and a $FLEET_SECRET_ profile;
OS updates, disk encryption, the setup script, webhooks, enroll secrets, agent options, and custom host vitals.
The export validated clean and the dry run reported no changes. I then applied the export to that local instance and compared every object before and after: 0 differences. GitOps exceptions and the Free tier were also exercised.
Then a read-only run against dogfood (4.94.0, Premium, Apple, Windows, and Android MDM, five fleets, App Store apps), with fleetctl built at dogfood's revision. It validated clean with no workarounds and the dry run reported no changes. Every fleet's policies, reports, scripts, software, and labels match it-and-security item for item; 41 of 42 profiles are byte-identical, and the 42nd differs only by now using $FLEET_GLOBAL_ENROLL_SECRET where Fleet stores the value. No secret value the skill knows about appears anywhere in the exported repo. Repeated with fleetctl built from main (the 4.95.0 scaffold): the new .agents/skills/fleet-gitops, AGENTS.md, CLAUDE.md, and GEMINI.md come through untouched, the validator runs, and the export passes with a server-matched fleetctl for the dry run. Preflight was run with fleetctl missing, too old, unconfigured, with no or an expired token, and with an unreachable host. ABM-specific settings weren't checked separately, and reading the dry run's values from .env is still covered by the unit tests only. The fixes from the later review rounds (stricter reconcile coverage, the wider secret scan, the Unassigned controls move, multi-package policy pinning) are covered by the unit tests and haven't been re-run against a live Fleet.

AI: Claude Code (claude-opus-5-5)
Summary by CodeRabbit
New Features
Added a Fleet GitOps export workflow to collect Fleet configuration and generate repository files from a scaffold.
Added checks for exported files, configuration differences, environment-variable placement, and potential secret exposure, with optional dry-run validation.
Added default package install and uninstall scripts for macOS, Windows, and Linux.
Bug Fixes
Improved package operations to handle common installer success codes and report failures.
Validation
Export reports now summarize findings and indicate when validation has not run for the current plan.
…new GitOps repo
Exports org settings, fleets, Unassigned, profiles, scripts, policies,
reports, labels, and software through read-only fleetctl api calls, fills
the fleetctl new scaffold in place, replaces secrets with environment
variables, and validates the result with a repo-vs-Fleet reconcile check
and fleetctl gitops --dry-run. Includes a parity checklist against
fleetctl generate-gitops and an .agents/skills pointer for other agents.
Remove unused imports, make wrapped prose strings explicit, explain the
non-UTF-8 fallback instead of an empty except, and probe for PyYAML with
importlib instead of an unused import. Also rename ambiguous one-letter
variables and an unused loop variable.
- Reconcile now compares contents, not just names: policy, report, and
label fields against Fleet's values, content hashes for scripts,
profiles, activations, and DDM assets, and software by identity and
settings. An unknown inventory kind fails instead of being skipped.
- Refuse plan paths that are absolute, contain .., or escape the repo
through a symlink; skip DDM assets whose names can't be file names.
- Keep the work folder owner-only and refuse one owned by someone else
or a symlink; add a clean command.
- all exits with validation's status.
- Write a dollar sign as \x24 inside double quotes so files with control
characters stay valid YAML; allow tabs in single quotes.
- Fix the checker's env unescape to match fleetctl for even backslash runs.
- Name the fleetctl timeouts and the report's validator cap.
- validate reads values Fleet can't return from the repo's gitignored .env
(or --env-file), since agents often can't see variables the user exports
- clear FAIL when an earlier step's work files are missing, and document --work
- SKILL.md: drop the Claude-only $ARGUMENTS line, add a compatibility field,
point to fleet-gitops for existing repos, and cover long-running commands,
sandboxes, non-interactive runs, and Windows
- allowed-tools pre-approves only this skill's script, not any python3 command
- test that the .agents pointer's frontmatter matches SKILL.md
Running the skill against dogfood (4.94.0) turned up:
- The dry run failed when a masked value wasn't in .env: the unquoted
******** mask parsed as a YAML alias. It's now passed quoted.
- enable_profile_validation was always written, and released fleetctl
rejects it. It's written only when Fleet returns it.
- Enroll secrets inside profiles and DDM assets were exported as plain
text. They're now written as the secret's variable, and reconcile
fills it in before comparing. Scripts get a REVIEW line instead.
- Fleet-maintained app scripts that were older copies of the catalog's
were pinned as custom scripts, which would stop Fleet's updates to
them. They're left out and listed for review (--keep-fma-scripts
keeps named ones); the API's *_script_edited flags win when present.
- Custom packages pinned Fleet's default install/uninstall scripts.
They're recognized against copies of pkg/file/scripts (kept in sync
by a test) and left out.
- hash_sha256 is no longer pinned for URLs that don't name a version;
policies reference those packages by package_path.
- A .deb and .rpm of one app now get -deb/-rpm names instead of a
fleet subfolder.
- Script platform hints never matched paths after a space or quote,
and missed udev; both fixed.
- SKILL.md's description still had <os>/<kind>, failing the pointer
test.
The skill's README is now an end-to-end guide for admins: install and
log in to fleetctl, add the skill, run the export, answer the review
questions, and turn on GitOps in CI in a safe order. A shorter version
for fleetdm.com lives at articles/export-fleet-to-gitops-with-an-ai-agent.md.
When fleetctl wasn't installed, configured, or logged in, preflight
failed with a generic "can't reach Fleet" and told users to run
`fleetctl login` before an address was set. Each setup FAIL now names
its step (install fleetctl, set the Fleet address, log in to Fleet,
reach Fleet) and the exact command, with the user's --context/--config
flags and the server's fleetctl version when known.
SKILL.md's new "Set up fleetctl" section has the agent install
fleetctl (after asking) and set the address itself, and send the user
to their own terminal to log in, so a password or API token never
passes through the agent. Both guides mention that the agent helps
with setup.
- Read an omitted enable_profile_validation as true in reconcile, so a
dropped or flipped value fails.
- Fail instead of quoting a YAML-unsafe value that a profile or DDM
asset also uses; quotes would land in the profile.
- Leave out profiles, DDM assets, and scripts holding a short enroll
secret as a whole word (gap note); warn on any other occurrence.
- Delete plan.json before collecting, so a failed collect leaves none.
- Compare org integration lists (Jira, Zendesk, Google) and certificate
authorities, dropping the fields held as variables on both sides.
- Never pin hash_sha256 for a file named for a channel (latest,
current, stable, nightly), even under a versioned folder.

Review comments at @.claude/skills/fleet-gitops-export/scripts/checks.py:
- Around line 290-293: Update the CA secret handling around is_ref and
_strip_env so each secret reference is checked against the planned variable for
its kind, index, and field, rather than accepting any name in self.env_names.
Reject or preserve as a mismatch any reference that does not match that specific
planned variable.
Review comments at @.claude/skills/fleet-gitops-export/scripts/collect.py:
- Around line 107-110: In the profile scan that sets short_secret_refs, scan
each activation for whole-token short secrets and long secrets, and mark the
parent profile when either is found. Update the planner’s profile export path
near _short_secret_gap to skip that profile and its activation together and emit
a gap note for the withheld item.
- Around line 107-110: Update _mark_secrets to scan setup script bodies in
sc["setup"]["script"] and software package scripts in sc["software"] using the
same env_refs and short_secret_refs handling as ordinary scripts. Ensure literal
enroll secrets in these bodies receive the existing replacement or omission
treatment before the planner writes them.
- Around line 110-112: Update render_report to report warnings for items that
were written to GitOps in a separate section from “Not represented in GitOps.”
Keep the embedded short enroll secret warning emitted through self.warn visible,
while ensuring the report identifies the item as present and requiring a check
before commit rather than absent from the repository.
Review comments at @.claude/skills/fleet-gitops-export/scripts/planner.py:
- Around line 1674-1678: Update _url_names_version to check channel names across
every URL path segment, not just the filename, before accepting a missing
version. Treat URLs containing latest, current, stable, or nightly in any path
segment as unpinned.

- Around line 800-808: Update reconcile to report integration and
certificate-authority keys present only in default.yml as failures, using the
existing “is in the repo but not in Fleet” wording used for top-level kinds.
Extend test_reconcile_compares_integrations_and_certificate_authorities with a
snapshot that omits a kind, then add that kind to default.yml and assert
reconcile reports it.

- Scan DDM activations, the setup experience script, and software
scripts for enroll secrets; fleetctl sends these as-is, so the item is
left out with a GAP note instead of committing the secret.
- Reconcile compares certificate authority secrets by the variable
planned for them, and reports integration and CA kinds only the repo
has as additions.
- A package under a channel folder (/latest/) pins its hash only when
the path names the version.
- The report lists exported items with warnings apart from gaps.
- The fleetd install script counts as Fleet's default only for a fleetd
.pkg (bundle ID com.fleetdm.orbit), as Fleet's getInstallScript does,
so a custom copy of it on another package is kept.
- Reconcile reads referenced files through a guard: a missing file or a
directory is a "(missing file)" value instead of an exception, and the
reference check reports a path that isn't a file.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 6 remain after this review.
Review comments:
- Scan every value of a software title (package and App Store app
configurations included), ADE profiles, and bodies that aren't UTF-8
(matched as bytes, UTF-16 too) for enroll secrets.
- The planner warns about a short secret inside a word only for items it
writes, and the report keeps warnings for left-out items out of
"Exported".
- Fleet's fleetd install script is never treated as a default: Fleet
uses it for fleetd's .pkg whatever is uploaded, and the API can't tell
fleetd apart, so a stored copy is kept.
- A package with no reported version doesn't pin hash_sha256.
- Reconcile reads repo-only SSO keys (Premium-only JIT flags on Free).
Robustness:
- export, place, and validate clear validation.json, which records the
plan's hash; report ignores results from another plan and says so.
- validate writes its results even when a step raises, fails when
nothing was compared, and catches fleetctl, validator, .env, and
timeout errors as findings.
- scaffold runs fleetctl new into an empty folder, so a rerun doesn't
copy an earlier export (or .env) into the pristine scaffold.
- Reconcile coerces YAML of unexpected shapes, keeps globs and paths
inside the repo, and compares each fleet file on its own.
- The orphan check skips OS junk files and gitignored paths.
- Missing endpoints on older servers (custom host vitals, Graph
credentials) read as empty.
- place records what it wrote even when it fails, and removes scaffold
examples no file occupies after plan.json edits.
- export warns when it replaces an edited plan.json; notes are deduped.
…erently
- When an Unassigned policy uses run_script or
resend_configuration_profile, Unassigned's controls go in
fleets/unassigned.yml (fleetctl checks those policies against that
file's own controls) and default.yml's controls are commented out.
- Labels and reports whose names aren't ASCII are left out with a gap
note; fleetctl rejects them.
- A policy on a multi-package title installs the package it picked
(software_package_id), named by hash_sha256, which is pinned for that
package.
- An MSI's default uninstall script depends on its upgrade code, as on
apply, so a stored product-code script isn't dropped when the title
has an upgrade code.
- fleets/no-team.yml is reserved like fleets/unassigned.yml.
- $FLEET_SECRET_ in YAML is escaped as literal text, except in
controls.name_template, where the server fills it in.
- Keys that start with a digit are quoted, and $ in keys is escaped.
- [ and { are allowed in file names (fleetctl accepts them in path:).
- Manual labels note that their hosts are written as host IDs.
- The enroll-secret scan covers policies, reports, labels, profile
metadata, YARA rules, and the Windows EULA, and catches JSON-, URL-,
and XML-escaped occurrences and base64 <data> payloads. Items holding
one are left out with a gap note.
- In agent options and features, a credential-named key (AWS secret
keys, tokens, passwords) or a value holding an enroll secret is
written as a variable the dry run reads back from Fleet, which returns
these settings unmasked.
- A package URL with credentials (user:pass@, or a token, key,
signature, or auth query parameter) is written as a variable read from
the software title.
- The plan's inventory keeps no values for items left out because of a
secret, keys left-out titles by hash, and leaves variable-held
settings out, so plan.json holds no secret.
- Reconcile no longer prints content hashes on a mismatch.
- A profile with a credential-looking key in plain text (Password,
SharedSecret, ...) gets a warning to move it into $FLEET_SECRET_.
- validate fails when a repo file holds the value of any variable the
dry run fetched, and warns when the work folder does.
- Any repo key that no comparison reads now fails ("isn't compared with
Fleet"), at the top level and under org_settings, settings, and
controls. Old key names fleetctl still maps get a hint; the list
mirrors pkg/spec/gitops_deprecations.go (checked by a test).
- Each $VARIABLE has to sit where the plan put it, and nowhere else, so
a value written out in its place or another variable fails.
- Newly compared: org_settings.mdm (Apple Business, VPP, Windows
automatic enrollment, end-user authentication, EULA files),
Microsoft Graph credentials, the number of enroll secrets, YARA rules,
org logos and their files, webhook intervals, custom host vitals,
fleet names, Apple account provisioning, setup experience files (the
setup script by hash, the ADE profile parsed, no bootstrap package
URL), a fleet's Google Calendar block, Android certificates, policy
resend and patch options, profile activations the repo adds, and
software setup experience, icons, .ipa configurations, and App Store
auto-update windows.
- Agent options and Windows update deadlines compare exactly (false,
0, and empty values count); omitted features read as fleetctl fills
them in (true, historical_data too); an FMA left without categories
reads as the catalog's.
- YAML items (policies, reports, labels) fail on fields Fleet has no
value for.
- macos_updates is written when update_new_hosts is on without a
minimum version.
- A package URL with credentials keeps its variable however a policy
reaches the package (Fleet lists it in software_package and packages),
so the token stays out of plan.json and reconcile messages.
- scaffold reads the layout from the fresh scaffold, so rerunning it
over an earlier export doesn't turn exported fleet files into
templates (place then failed).
- Multi-version App Store apps and .ipa configurations reconcile
cleanly; a fleet entry's paths resolve from the fleet file.
- An App Store app's VPP location is compared.
- The leak check looks only for secret values, not webhook URLs or IdP
metadata a script or profile may share.
- Agent options and non-scalar features differences don't print values.
- The secret scan reads only fields the export writes.
- Variables for Unassigned controls name the file that holds them.

Fix .env parsing of a quoted value that has a trailing comment.
A line such as A="abc" # note starts with a quote but does not end with one. The parser therefore treats it as the start of a multi-line value. It then appends the following lines to A until it finds a line that ends with ". Variables on those lines are never read. A ends up with a wrong value.
dry_run_env then reports the lost variables as "not set" and uses placeholders for them. The dry run also gets a wrong value for A. Trailing comments after quoted values are common in .env files. Match a complete quoted value, with an optional comment, before you fall back to the multi-line case.

cmd_place accepts an edited plan.json, and _write_file() uses f["blob"] without validation. A traversal value or a symlink can make the read leave work/blobs and copy a local file into the GitOps repository.

- Around line 719-722: Update _difference to redact non-plain values in every
keyed section recognized by the checker, including org_settings sections, while
preserving the existing agent_options redaction and plain-scalar reporting
behavior. Reuse the checker’s keyed-section definition, such as KEYED_SECTIONS,
so credential values are not included in validation messages or reports.
Review comments at @.claude/skills/fleet-gitops-export/scripts/collect.py:
- Around line 177-183: Update the bytes-handling path around
`body.decode("utf-8")` to check raw UTF-16 encodings when the decoded body
contains NUL bytes, and route any secret match through the existing
`plain_secret_refs` mechanism so the item is left out. Preserve the current
UTF-8 matching behavior and reuse the existing secret values and exclusion flow
rather than introducing a separate one.
Review comments at @.claude/skills/fleet-gitops-export/scripts/gitops_export.py:
- Line 429: The generated rerun commands in render_report interpolate paths
without shell quoting. Quote the script path and target directory with
shlex.quote in the Python validate command, and quote the target directory in
the cd command; make shlex available to render_report.
Review comments at @.claude/skills/fleet-gitops-export/scripts/placer.py:
- Line 130: Update _env_docs to route writes for .env.example, .gitignore,
README.md, the workflow file, and gitops.sh through target() before writing, so
each destination receives the existing containment check regardless of whether
the pristine scaffold contains it.

- Around line 239-244: Update the quoted-value handling in the environment
parser so it recognizes a complete quoted value followed by an optional trailing
comment and stores only the enclosed value. Fall back to multiline parsing only
when the quoted value is genuinely unclosed, preserving subsequent variable
parsing and correct values used by dry_run_env.

- Reconcile doesn't print values that aren't plain scalars for
integrations, certificate authorities, and SSO settings, where a
credential written out in the repo could otherwise reach
validation.json and the report.
- A body that decodes as UTF-8 but holds NULs (UTF-16 without a
byte-order mark) is also matched in UTF-16.
- The report's rerun commands shell-quote their paths, and the
concatenated line is explicit.
- place writes .env.example, .gitignore, README.md, the workflow, and
gitops.sh through the containment check, and refuses a blob name in
plan.json that isn't a digest inside the work folder's blobs.
- .env reading accepts a quoted value followed by a comment.

fleet-gitops-export, an agent skill that turns a live Fleet instance into a ready-to-use GitOps repo laid out exactly the wayfleetctl newscaffolds it. It's meant to replacefleetctl generate-gitops, which exports the right data in a different layout.generate-gitopsis unchanged.What it does (
.claude/skills/fleet-gitops-export/):fleetctlhasnew, that it's logged in as a global admin, the server URL and version, the tier, MDM status, GitOps-mode exceptions, and that the target directory is empty. Whenfleetctlisn't set up, each FAIL names the missing step (install fleetctl, set the Fleet address, log in to Fleet, reach Fleet) with the exact command. The agent installsfleetctl(after asking) and sets the address itself; the user logs in in their own terminal, so a password or API token never passes through the agent.fleetctl new, then scans its output (fleet templates,paths:globs,platforms/<os>/<kind>/folders). Every destination is derived from that scan, not hardcoded, so the export picks up whatever scaffold the user'sfleetctlships.fleetctl api, GET only, on an allowlist of the endpointsgenerate-gitopsuses. The skill never sees the API token. It writes a reviewable placement plan that holds no secret values.default.ymland the fleet files in place, keeping the templates' comments. Commented-out examples become real settings where Fleet has them, and example data Fleet doesn't have is deleted. It writes.env.example, a README section, and the workflowenv:entries.fleet-gitopsvalidator (scaffolded from fleetctl 4.95.0; skipped with older versions), parses the YAML, checks references and orphans, reconciles the repo against Fleet item by item and field by field (content hashes for scripts, profiles, and DDM assets), and runsfleetctl gitops --dry-run --delete-other-fleets. Reconcile fails on any settings key it doesn't compare and on a$VARIABLEthat isn't where the plan put it, and validate fails if a secret value it fetched turns up in any repo file. Secret values go only into that process's environment. Values Fleet can't return (FLEET_SECRET_*variables, masked tokens) come from the exported repo's gitignored.env(or--env-file), which the user fills in themselves, so they never pass through the agent.The design choices worth reviewing are in
references/mapping.md:default.yml, because fleetctl accepts controls in only one ofdefault.ymlandunassigned.yml. When an Unassigned policy usesrun_scriptorresend_configuration_profile, they go inunassigned.ymlinstead, because fleetctl checks those policies against that file's own controls.$is escaped as\$. fleetctl expands$VARin YAML and profiles, andgenerate-gitopsdoesn't escape it.install_script_edited,uninstall_script_edited) but the API doesn't return it yet, so a stored script that's close to the catalog's current one is treated as an older copy of Fleet's script, left out, and listed for review;--keep-fma-scriptskeeps named ones.

Testing
Added/updated automated tests:
python3 -m unittest discover -s .claude/skills/fleet-gitops-export/scripts/tests(96 tests, offline; passing on Python 3.9.6 and 3.15). They cover$-escaping against a port of fleetctl's expansion, YAML quoting, the read-only guards, path containment, the private work folder, the.envreader and which dry-run values it supplies (including the quoted mask), clear failures when an earlier step's work files are missing, preflight's setup messages, the.agentspointer staying in sync, enroll-secret spans and variables, Fleet-maintained app script classification, default package script matching (and the copies staying in sync withpkg/file/scripts), unpinned hashes andpackage_path,.deb/.rpmnaming, script platform hints, and an end-to-end plan, placement, and reconcile on the realfleetctl newtemplates, including a feature-rich synthetic Fleet (Apple Business, VPP, EULAs, SSO, setup experience, App Store apps, Android certificates) that has to reconcile with no findings.QA'd all new/changed functionality manually. On a local throwaway Fleet (Premium dev license, Apple and Windows MDM with self-signed certs), with three fleets plus Unassigned and fixtures covering:
run_script,install_software,resend_configuration_profile, and a patch policy;$FLEET_SECRET_profile;The export validated clean and the dry run reported no changes. I then applied the export to that local instance and compared every object before and after: 0 differences. GitOps exceptions and the Free tier were also exercised.
Then a read-only run against dogfood (4.94.0, Premium, Apple, Windows, and Android MDM, five fleets, App Store apps), with fleetctl built at dogfood's revision. It validated clean with no workarounds and the dry run reported no changes. Every fleet's policies, reports, scripts, software, and labels match
it-and-securityitem for item; 41 of 42 profiles are byte-identical, and the 42nd differs only by now using$FLEET_GLOBAL_ENROLL_SECRETwhere Fleet stores the value. No secret value the skill knows about appears anywhere in the exported repo. Repeated with fleetctl built frommain(the 4.95.0 scaffold): the new.agents/skills/fleet-gitops,AGENTS.md,CLAUDE.md, andGEMINI.mdcome through untouched, the validator runs, and the export passes with a server-matched fleetctl for the dry run. Preflight was run with fleetctl missing, too old, unconfigured, with no or an expired token, and with an unreachable host. ABM-specific settings weren't checked separately, and reading the dry run's values from.envis still covered by the unit tests only. The fixes from the later review rounds (stricter reconcile coverage, the wider secret scan, the Unassigned controls move, multi-package policy pinning) are covered by the unit tests and haven't been re-run against a live Fleet.AI
