feat: add flowspec doctor and GPG signing by jpoley · Pull Request #1239 · jpoley/flowspec

jpoley · 2026-04-05T23:17:25Z

Summary

Adds flowspec doctor health-check command and flowspec gpg agent signing module with full CLI wiring, tests, and documentation.

All Copilot review findings from PRs #1236, #1237, and #1238 are resolved in this single DCO-signed commit.

What's included

flowspec doctor command:

Checks: CLI version, Python 3.11+, tool availability (backlog, beads), workflow config validation, agent file naming (flow.*.agent.md with strict 4-part validation), constitution presence
Rich table output with fix suggestions

flowspec gpg subcommands (setup/status/rotate):

Key generation via --status-fd for reliable fingerprint extraction
40-character hex fingerprint validation before keyring storage
Secret key verification by exact fingerprint (not email)
Git signing configuration with secret key presence check
Key rotation with confirmation prompt

Copilot findings resolved (all 3 rounds):

Fingerprint extraction via --status-fd instead of --list-keys (avoids wrong key with duplicate emails)
Fingerprint format validation (40-char hex, normalized to uppercase)
Secret key verification by fingerprint, not email
Strict flow.<phase>.agent.md pattern validation (rejects flow.agent.md, flow..agent.md)
Mocked httpx.get in doctor tests (no network dependency)
Unused stderr variable fixed (Ruff F841)
Docs: all GPG export/delete commands use fingerprint, not email
Docs: removed false telemetry integration claims
CLI wiring: both gpg sub-app and doctor command registered in main app

Closes #1221 #1222 #1223 #1224 #1225 #1226

Test plan

uv run ruff check . — all checks passed
uv run ruff format --check . — all files formatted
uv run pytest tests/ -x -q — 3526 passed, 42 skipped, 0 failures

Pull request overview

Adds two new end-user features to the Flowspec CLI: a flowspec doctor environment health-check command and a flowspec gpg subcommand suite for agent GPG key management + git commit signing, including tests and a user guide.

Changes:

Introduce flowspec doctor diagnostics (version/Python/tooling/workflow config/agent naming/constitution) with Rich table output.
Add GPG signing core (signing.py) and CLI wiring (gpg_cli.py, __init__.py) for setup/status/rotate workflows.
Add initial test coverage for both modules and a new documentation guide for GPG signing.

+            "user.signingkey",
+            "ABCD1234",
+        ]


The tests use short/invalid fingerprints (e.g., "ABCD1234") in the keyring and GPG outputs, but the signing module generates/validates 40-character hex fingerprints. Using non-40-hex fixtures can mask bugs around fingerprint normalization/validation; update the test data to use realistic 40-char hex fingerprints consistently (including the expected git config values).

+    fingerprint = get_key_fingerprint()
+    if not fingerprint:
+        raise GPGError("No agent GPG key found. Run generate_agent_key() first.")
+
+    # Verify the exact secret key fingerprint is still present in the GPG keyring
+    stdout, _, returncode = _run_gpg_command(
+        ["--list-secret-keys", "--with-colons", fingerprint]
+    )
+    fingerprint_found = any(
+        line.startswith("fpr:") and line.split(":")[9] == fingerprint
+        for line in stdout.splitlines()
+    )


configure_git_signing() compares the stored fingerprint against the --with-colons output case-sensitively (line.split(':')[9] == fingerprint). If the keyring value is lower-case (or otherwise not normalized), this can incorrectly report the secret key as missing. Normalize the fingerprint (e.g., .upper()) before both the GPG call and the comparison (and ideally reuse the same normalization in get_key_fingerprint()).

Copilot · 2026-04-05T23:21:37Z

+    """
+    try:
+        fingerprint = keyring.get_password(KEYRING_SERVICE, KEYRING_USERNAME)
+        return fingerprint


get_key_fingerprint() claims to return a 40-character hex fingerprint, but currently returns whatever the keyring contains without validation/normalization. Consider validating (len==40 and hex) and normalizing (uppercase) here; if invalid, return None (or raise a specific error) so downstream commands don’t fail with confusing GPG errors.

Suggested change

return fingerprint

if fingerprint is None:

return None

fingerprint = fingerprint.strip()

if len(fingerprint) != 40:

return None

try:

int(fingerprint, 16)

except ValueError:

return None

return fingerprint.upper()

Key design decisions in signing module: - Fingerprint normalization centralized in get_key_fingerprint() (strip, uppercase, 40-char hex validation, logging on failure) - Key generation uses --status-fd for reliable fingerprint extraction - Secret key verification uses exact fingerprint match (case-insensitive) - All test mocks use realistic 40-char hex fingerprints via TEST_FP constant Doctor module improvements: - httpx imported at module level (coding standard compliance) - Strict flow.<phase>.agent.md validation (rejects flow.agent.md) - UTF-8 encoding on all file I/O - Version check distinguishes "confirmed current" from "could not check" Documentation quality: - All GPG commands use fingerprint (not email) to avoid ambiguity - Broken related-doc links replaced with anchor links - Security note about ~/.gnupg file permissions added - Manual deletion warns about keyring cleanup Closes #1221 #1222 #1223 #1224 #1225 #1226 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Signed-off-by: jason poley <jason.poley@gmail.com>
