Feat/declarative ssh agent - #417
Conversation
## Summary Implement fully declarative SSH key management for kyber using keychain and improve agenix secret deployment with automatic activation scripts. ## Changes ### SSH Agent Management - Add keychain package for Linux systems - Create `home-manager/services/ssh-agent.nix` module - Configure keychain to automatically load SSH keys on login - Use modern keychain flags (--confirm) to handle passphrase-protected keys ### Agenix Deployment - Add activation scripts to ensure SSH directory exists - Implement automatic decryption and deployment of GitHub SSH key - Deploy secrets during home-manager activation if they don't exist ### Fish Shell Enhancements - Add `_ssh_add_github` function for manual key loading - Add `sag` abbreviation for quick GitHub key addition - Initialize keychain in fish loginShellInit for automatic agent setup ### Documentation - Expand kyber README with comprehensive SSH key management docs - Add troubleshooting section for common issues - Document passphrase-protected key handling ## Architecture **Keychain Integration:** - Automatically starts ssh-agent on first login - Persists ssh-agent across shell sessions - Gracefully handles passphrase-protected keys with --confirm flag **Agenix Deployment:** - Secrets are decrypted from galactica's encrypted store - Deployed to ~/.ssh/id_ed25519_github with 0600 permissions - Activation runs before home-manager linkGeneration phase **GitOps Workflow:** - All configuration is declarative in Nix - SSH keys sync automatically from galactica via agenix - `make switch` deploys everything without manual intervention ## Testing Verified on kyber: - keychain package installed - SSH key decryption working - Manual key addition via `sag` command - Documentation complete 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Use ssh-add directly instead of eval'ing keychain output, since keychain outputs bash syntax that fish can't parse. The function now: 1. Checks if ssh-agent is running 2. Starts ssh-agent if needed (using fish syntax) 3. Uses ssh-add directly to add the GitHub key 4. Prompts for passphrase if needed 5. Verifies and tests GitHub connection 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Update grep pattern to check for both key filename and email address. Also add fallback to test GitHub connection even if verification fails. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Update agenix configuration to sync ~/.ssh/id_github from galactica instead of ~/.ssh/id_ed25519. The id_github key is the GitHub CLI-authorized key with fingerprint SHA256:WA5wUwzlgMgujLm0U9gZBGTkGXiid5PfgDjMKJhHUis. ## Changes - Update galactica/secrets.nix to encrypt id_github.age - Update kyber/secrets.nix to reference id_github.age - Update kyber/default.nix to decrypt id_github.age - Keep deployment path as ~/.ssh/id_ed25519_github on kyber ## Next Steps on Galactica 1. Encrypt the correct key: cd ~/dotfiles make encrypt-key-galactica KEY_FILE=~/.ssh/id_github 2. Commit and push: git add named-hosts/galactica/keys/id_github.age git commit -m 'chore(agenix): encrypt GitHub SSH key (id_github)' git push 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Configure agenix to share GPG key between galactica and kyber, enabling signed commits on kyber using the same GPG key. ## Changes - Update galactica/secrets.nix: Share GPG key with allMachines - Update kyber/secrets.nix: Add GPG key secret reference - Add GPG import activation script on kyber - Configure GPG and Git signing on kyber (matching galactica) - Enable gpg-agent with same settings as galactica ## Features - Automatic GPG key import on activation - Git configured to sign commits by default - GPG agent with 30min/2hr cache TTLs - Idempotent: skips import if key already exists ## Next Steps on Galactica Run: make rekey-galactica This will re-encrypt gpg.age to include kyber's public key. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Code Review
This pull request introduces a declarative SSH agent setup using keychain for Linux environments. It adds a new fish function _ssh_add_github to manually add a GitHub SSH key, and updates the Nix configuration to deploy SSH and GPG keys via agenix. The changes are mostly well-structured, but I've found a critical issue in the new fish function and some inconsistencies in the documentation. My review includes suggestions to fix the function's logic and update the documentation to match the code changes.

The logic for adding the SSH key is overly complex and contains a critical error. The command on line 17, bash -c 'eval $(keychain ...)', is incorrect for a fish shell. The environment variables set by eval will be scoped to the bash subshell and won't be available in the parent fish shell, making the command ineffective.
The subsequent logic (lines 20-26) correctly checks for and starts ssh-agent if needed, and then adds the key with ssh-add. This is a robust approach.
I suggest simplifying the script to remove the confusing and non-functional keychain call. The remaining logic is sufficient to add the key, prompting for a passphrase if necessary. While this makes the keychain availability check on line 9 redundant for this specific function, keychain is still used for agent initialization at login, so ssh-add should work correctly here.
# Ensure ssh-agent is running. keychain should have started it on login,
# but we can start it here as a fallback if needed.
if not ssh-add -l >/dev/null 2>&1
echo "ssh-agent not running. Starting it..."
eval (ssh-agent -c)
end
# Add the key directly. This will prompt for a passphrase if there is one.
echo "🔑 Adding GitHub SSH key to ssh-agent..."
ssh-add ~/.ssh/id_ed25519_github

Use pinentry-curses instead of the default pinentry for kyber. This allows GPG to prompt for passphrases in terminal environments. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Actionable comments posted: 10
🧹 Nitpick comments (4)
named-hosts/kyber/default.nix (1)
105-136: GPG and Git signing configuration looks good.The GPG agent, signing configuration, and Git integration are properly set up. Consider extracting the hardcoded key ID (
C2E97FCFF482925Don line 92 and email on lines 109, 118) into a variable for maintainability, but this is optional for personal dotfiles.home-manager/services/default.nix (1)
9-9: Inconsistent import pattern compared to other services.The
sshAgentimport doesn't pass parameters, while all other service imports in this file use{ inherit pkgs; }. Even thoughssh-agent.nixis a home-manager module that receives{ config, lib, pkgs, ... }from the module system, maintaining consistency with the established pattern in this file would improve code clarity.Consider applying this diff for consistency:
- sshAgent = import ./ssh-agent.nix; + sshAgent = import ./ssh-agent.nix { inherit pkgs; };Then update
ssh-agent.nixto accept and ignore the parameter if needed, or restructure it as a service package similar to the others.home-manager/services/ssh-agent.nix (1)
21-23: Clarify passphrase assumption for default key.The comment states "no passphrase" for the default key, but there's no enforcement or verification of this assumption. If a user adds a passphrase to
id_ed25519, the--confirmflag will skip it in non-interactive contexts, which may not be obvious.Consider updating the comment to be more explicit:
- # Always try to load the default key (no passphrase) + # Always try to load the default key (expected to have no passphrase) + # If this key requires a passphrase, it will be skipped by --confirm in non-interactive contexts if test -f ~/.ssh/id_ed25519 set -a keys ~/.ssh/id_ed25519 endhome-manager/programs/fish/functions/_ssh_add_github.fish (1)
3-6: Use$HOMEinstead of hardcoded~/.sshpath for consistency.While
~typically expands in Fish, using$HOMEis more explicit and consistent with Nix conventions.- if not test -f ~/.ssh/id_ed25519_github - echo "❌ GitHub SSH key not found at ~/.ssh/id_ed25519_github" + if not test -f $HOME/.ssh/id_ed25519_github + echo "❌ GitHub SSH key not found at $HOME/.ssh/id_ed25519_github" return 1 end

Simplify redundant SSH agent initialization flow.
The function has confusing redundant logic:
- Line 17 uses
bashto evaluate keychain (then ignores the result) - Lines 20-23 check and potentially start ssh-agent
- Line 26 directly adds the key
This creates unnecessary complexity. Since keychain is already initialized in loginShellInit (from ssh-agent.nix), the function should verify the agent is running and add the key only if not already present.
Apply this diff to simplify:
- # Initialize keychain and add the GitHub key
- echo "🔑 Adding GitHub SSH key to keychain..."
- # Use bash to evaluate keychain output, then use ssh-add
- bash -c 'eval $(keychain --eval --quiet --confirm ~/.ssh/id_ed25519_github 2>/dev/null); ssh-add -l' >/dev/null 2>&1
-
- # Alternative: directly use ssh-add if keychain already initialized ssh-agent
+ # Check if ssh-agent is running (keychain should have started it)
if not ssh-add -l >/dev/null 2>&1
- # Start ssh-agent if not running
- eval (ssh-agent -c)

In home-manager/programs/fish/functions/_ssh_add_github.fish around lines 17 to
26, remove the redundant bash keychain eval and the manual ssh-agent startup;
instead simply check whether the github key is already loaded and, if not, call
ssh-add to add it. Implement this by running ssh-add -l and testing for the
presence of ~/.ssh/id_ed25519_github (or its key fingerprint/name) and only call
ssh-add ~/.ssh/id_ed25519_github when that check fails; do not attempt to start
ssh-agent or invoke keychain here since agent initialization is handled in
loginShellInit.

🌐 Web query:
ssh-add -l output format what fields does it show
💡 Result:
ssh-add -l prints one line per identity with these fields:
- bits — key size (e.g. 4096)
- fingerprint — fingerprint of the public key (default SHA256:... unless changed with -E)
- comment — free‑form comment (usually user@host or whatever was set in the pubkey); ssh-agent does not record the source filename.
- algorithm — key type in parentheses (e.g. (RSA), (ED25519))
Example:
4096 SHA256:abc... user@host (RSA). (mankier.com)
Citations:
The grep pattern is ineffective; verification relies entirely on the hardcoded email.
The ssh-add -l command does not output the filename id_ed25519_github; it only shows the comment field (usually user@host format). This means the first pattern in the regex will never match. The verification succeeds only if the public key's comment is exactly shunkakinoki@gmail.com. If the key was generated with a different comment (e.g., shun@laptop or user@hostname), verification will fail despite the key being correctly added.
Either document that the key must be generated with this specific comment, or use a more robust check (e.g., verify by fingerprint or check ssh-add -L for the full key).
🤖 Prompt for AI Agents
In home-manager/programs/fish/functions/_ssh_add_github.fish around line 29, the
current grep against ssh-add -l relies on a filename that never appears and on a
hardcoded email comment; replace this with a robust check using ssh-add -L
(which prints the public keys) and match either the public key blob or the key
fingerprint (or both) instead of the comment alone, e.g., call ssh-keygen -lf on
each public key line from ssh-add -L to compare the expected fingerprint, or
grep the full public key string/comment from ssh-add -L; alternatively, if you
prefer keeping the simple approach, update the function comment to require
generating the key with the specific email and document that constraint.

Fallback error handling could be more robust.
The fallback path (lines 34-39) returns the status of ssh -T git@github.com, but this command always exits with status 1 for successful authentication (GitHub's design). This makes the return value misleading.

🌐 Web query:
keychain --confirm flag behavior non-interactive ssh passphrase
💡 Result:
Short answer: --confirm tells keychain to add keys with SSH confirmation enabled (ssh-add -c). That makes every use require an interactive confirmation via SSH_ASKPASS; in non‑interactive contexts (cron, CI, headless shells without SSH_ASKPASS) the key will either block waiting for confirmation or fail, so it is unsuitable for non‑interactive use. [1][2]
What to do
- Remove --confirm when you need non‑interactive access (let keychain load keys normally). [1][2]
- Or provide a working SSH_ASKPASS program and DISPLAY/X11 or an alternative GUI prompt so confirmations can succeed in your environment. [1][2]
- Alternative: preload the key into an agent without -c (ssh-add without -c) or use OS keychain integration (macOS UseKeychain / ssh-add options) depending on platform. [2][3]
Sources
- keychain man page (--confirm description). [1]
- ssh-add man / docs describing -c (confirmation via SSH_ASKPASS) and effects on non‑interactive runs (quoted/summary). [2]
- Platform notes (macOS UseKeychain / ssh-add behavior) for alternatives. [3]
Remove --confirm flag or provide SSH_ASKPASS in non-interactive login contexts.
The --confirm flag makes ssh-add require interactive confirmation for every key usage via SSH_ASKPASS. In non-interactive contexts (headless servers, systemd services without a display), this will block or fail. The fallback or true won't prevent the blocking during evaluation. Either remove --confirm to allow normal key loading, or ensure SSH_ASKPASS and a display mechanism (DISPLAY/X11 or alternative GUI prompt) are available in this service environment.
🤖 Prompt for AI Agents
In home-manager/services/ssh-agent.nix around lines 34-35, remove the
problematic --confirm flag from the keychain invocation or ensure an
SSH_ASKPASS-based prompt is available in the service environment; specifically,
either drop --confirm so keys are loaded non-interactively (preventing blocking
in headless/systemd contexts), or set up and export SSH_ASKPASS and any required
DISPLAY/X11 or alternative GUI prompt before invoking keychain so confirmations
can be handled without a tty.

Error suppression may hide legitimate keychain failures.
The ^/dev/null; or true pattern suppresses all errors from keychain, which could hide configuration problems or missing dependencies. While this prevents login shell interruption, it makes debugging difficult.
Consider logging suppressed errors to a file for debugging:
- eval (keychain --eval --quiet --confirm $keys ^/dev/null; or true)
+ eval (keychain --eval --quiet --confirm $keys 2>>~/.keychain-errors.log; or true)Or at minimum, document why errors are suppressed:
# Use --quiet to suppress most output, --eval to set environment variables
- # --confirm will skip keys that need a passphrase in non-interactive contexts
+ # --confirm will skip keys that need a passphrase in non-interactive contexts
+ # Errors are suppressed to prevent login shell failures if keychain has issues

The GPG key import command doesn't respect the DRY_RUN_CMD variable, which means it will always execute even during dry-run mode. This could cause unintended side effects when users run with --dry-run. The command should be prefixed with $DRY_RUN_CMD to maintain consistency with the rest of the script.

The function starts ssh-agent with the -c flag for csh-style output, but Fish shell requires fish-style output using the -c flag is incorrect. Fish can handle the default output format, but using ssh-agent -c | source would be more appropriate for Fish shell.

The GPG key fingerprint "C2E97FCFF482925D" is hardcoded in the deployment script. If this key needs to be changed or if this configuration is shared across different users/machines, this hardcoded value will cause issues. Consider making this configurable or documenting that this is specific to a particular user.

The gpgSign = true settings are redundant. The signByDefault = true at line 117 already enables signing for all commits and tags. The explicit commit.gpgSign and tag.gpgSign settings in extraConfig are unnecessary and should be removed to avoid duplication.

The error handling with ^/dev/null; or true combined with the semicolon inside the eval may cause issues. In Fish, the or operator should typically be outside the eval command substitution. Consider restructuring to eval (keychain --eval --quiet --confirm $keys 2>/dev/null) and handling errors separately, or ensuring the error handling logic is correct for the intended behavior.

2-6: Consider inlining the variable or implementing conditional logic.The
enableGpgSigningvariable is defined but only used once. If GPG signing is truly meant to be enabled on all systems, this variable adds no value and can be inlined. Alternatively, if you plan to make this conditional per system (as the comment on line 86 suggests), implement that logic here.If keeping it simple and always enabled:
-let - # Determine if we're on a system where GPG signing should be enabled - # Enable on all systems - enableGpgSigning = true; -in { programs = { git = {And inline on line 88:
- signByDefault = enableGpgSigning; + signByDefault = true;

54-63: LGTM: GitHub SSH key mapping is correctly configured.The secret mapping has been appropriately updated to use a dedicated GitHub SSH key with correct deployment path and permissions.
130-137: LGTM: GPG agent configuration is appropriate for server environment.The configuration correctly uses
pinentry-ttyfor terminal-only access and sets reasonable cache timeouts. Disabling SSH support is appropriate if managing SSH keys separately via ssh-agent/keychain.
139-143: LGTM: GPG_TTY is correctly configured for dynamic evaluation.This properly sets
GPG_TTYin the Fish shell initialization where it will be evaluated dynamically per session. The comment clearly explains the rationale, and usinglib.mkAfterensures correct ordering.
- Remove Linux-only condition so it runs on macOS too - Add silent failure handling with 2>/dev/null - Only import if decryption succeeds (authorized SSH key required) - Keeps GPG key management consistent across all systems This ensures galactica can also auto-import the GPG key if needed (e.g., after fresh install or keyring corruption), while failing gracefully on unauthorized systems. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
