Use Go modules and target Go 1.22+ - Follow standard Go naming conventions (camelCase for unexported, PascalCase for exported) - Add godoc comments for all exported types, functions, and methods -- Structure comments: `// FunctionName does X` (not `// does X`) - Use structured logging via Mattermost API: `p.API.LogError("message", "key", value)` - Never log secrets or sensitive data; redact fields like `ClientSecret` - Return meaningful errors with context: `fmt.Errorf("failed to X: %w", err)` - Use thread-safe patterns (e.g., `sync.RWMutex` for shared state) - Write unit tests for all packages (`*_test.go` files) -- Keep functions focused and single-purpose ### TypeScript/React Frontend - Use TypeScript strict mode (`strict: true` in tsconfig.json) -

Use CSS modules for styling (PostCSS) - Write tests with Vitest and React Testing Library -- Export types/interfaces separately from implementation - -### Testing Guidelines -- **Go**: Unit tests in `*_test.go` files, use table-driven tests where appropriate -- **React**: Component tests with Vitest + React Testing Library, test user interactions and state -- **Integration**: Use docker-compose stack for end-to-end validation -- Test coverage: Focus on critical paths (auth flows, config validation, user provisioning) -- Mock external dependencies (HTTP clients, Mattermost API calls) ## Security Requirements - **HTTPS only**: Enforce HTTPS for issuer URLs (unless `AllowInsecureIssuer` is explicitly enabled for dev) - **Never log secrets**: Redact `ClientSecret`, tokens, and sensitive claims in logs - **State management**: Use nonce/state per auth request, stored in plugin KV store with short TTL - **Token handling**: Keep ID/access tokens in-memory only; encrypt refresh tokens before persistence -- **Input validation**: Validate and sanitize all user inputs (URLs, redirect URIs, scopes) - **PKCE required**: Use Authorization Code + PKCE flow for all OIDC interactions - **Error messages**: Return sanitized error messages to clients; log detailed errors server-side -## Development Workflow - -### Setup and Build +## Agent Skills +For detailed workflows, refer to `.github/skills/`: +- **dev-environment** -

-### Architectural Patterns -- **Server responsibilities**: Authorization Code + PKCE flow, claim mapping, user provisioning, config validation, KV-store session tracking, structured logging (Zap), metrics (Prometheus), tracing (OpenTelemetry) -- **Webapp responsibilities**: Login CTA, admin-console configuration UI, client-side validation -- **Configuration**: All secrets via env vars or Mattermost plugin KV store -- **Observability**: Structured logs with correlation IDs, Prometheus metrics for auth attempts/latency, OpenTelemetry traces - -## Common Pitfalls -- Don't commit secrets or credentials to source code -- Don't create ad-hoc folders; use established structure -- Don't log sensitive data (tokens, secrets, PII) -- Don't use global state without proper locking -- Don't skip error handling or return generic errors -- Don't hardcode URLs or magic strings; use constants -- Avoid Unicode in code unless existing files use it -- Update documentation when changing workflows or APIs - ## Important References -- **Architecture**: See `docs/ARCHITECTURE.md` for component details, security model, and flows -- **Dev Environment**: See `docs/DEV_ENV.md` for local setup and Keycloak bootstrap -- **Main README**: `README.md` for installation, configuration, and usage -- **Makefile**: Check `Makefile` for all available build targets -- **CI Workflows**: `.github/workflows/` for continuous integration pipelines - -## Contribution Guidelines -- Use trunk-based development (feature branches merge to `main`) -- Every feature branch must include tests and documentation updates -- Run linters and tests before committing -- Write clear commit messages describing changes -- Update relevant documentation (README, ARCHITECTURE, DEV_ENV) when changing functionality -- Release artifacts go in `build/` with semantic versioning -- Use `make package` to create plugin bundles, never manually tar files +- **Architecture**: `docs/ARCHITECTURE.md` -

Cross-check architectural decisions with `docs/ARCHITECTURE.md` - Verify environment setup against `docs/DEV_ENV.md` - Use `scripts/` for automation instead of ad-hoc shell commands -- Ensure observability hooks (logs, metrics, traces) are in place for new flows -- Ask for clarification rather than making assumptions about security or configuration diff --git a/.github/skills/config-migration/SKILL.md b/.github/skills/config-migration/SKILL.md index 3851506..0f169e9 100644 --- a/.github/skills/config-migration/SKILL.md +++ b/.github/skills/config-migration/SKILL.md @@ -61,7 +61,10 @@ mmctl config set PluginSettings.Plugins.com.mm.oidc --config oidc-config-backup. # Or restore individual settings mmctl config set PluginSettings.Plugins.com.mm.oidc.issuer_url "https://keycloak.example.com/realms/mattermost" mmctl config set PluginSettings.Plugins.com.mm.oidc.client_id "mm-oidc" -mmctl config set PluginSettings.Plugins.com.mm.oidc.client_secret "$(vault kv get -field=secret secret/mm-oidc)" + +# Restore client secret securely without exposing it in shell history or process listings +vault kv get -field=secret secret/mm-oidc | \ + mmctl config set PluginSettings.Plugins.com.mm.oidc.client_secret --value-from-stdin ``` ### Verify Configuration @@ -147,8 +150,13 @@ jq '.issuer_url = "https://keycloak.example.com/realms/mattermost"' staging-conf jq '.redirect_url = "https://chat.example.com/plugins/com.mm.oidc/callback"' prod-config.json > prod-config.json jq '.client_id = "mm-oidc-prod"' prod-config.json > prod-config.json -# Import production client secret from vault -jq --arg secret "$(vault kv get -field=secret secret/mm-oidc-prod)" '.client_secret = $secret' prod-config.json > prod-config.json +# Import production client secret from vault securely +# Using temporary file with restricted permissions to avoid command line exposure +vault kv get -field=secret secret/mm-oidc-prod > /tmp/secret.tmp +chmod 600 /tmp/secret.tmp +jq --rawfile secret /tmp/secret.tmp '.client_secret = $secret' prod-config.json > prod-config-final.json +rm -f /tmp/secret.tmp +mv prod-config-final.json prod-config.json # Import to production mmctl --server https://chat.example.com config set PluginSettings.Plugins.com.mm.oidc --config prod-config.json From 179e2840f47172f632e5408cf5a7ea9f90d3a7a6 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Sun, 11 Jan 2026 00:51:15 +0000 Subject: [PATCH 5/5] Fix additional security vulnerabilities: token and secret exposure in process args - release-management: Replace curl with gh CLI for GitHub API to avoid token exposure - Primary method: Use 'gh api' and 'gh release upload' (no token in process args) - Alternative documented: Use temp file with restricted permissions if curl required - troubleshooting: Fix client_secret exposure in OIDC token exchange example - Use temp file with chmod 600 and --data-urlencode @file to read secret - Add cleanup step to remove temp file after use - Both fixes prevent secrets from appearing in shell history or process listings Co-authored-by: insoln <11380274+insoln@users.noreply.github.com> --- .github/skills/release-management/SKILL.md | 33 +++++++++++++--------- .github/skills/troubleshooting/SKILL.md | 15 ++++++++-- 2 files changed, 32 insertions(+), 16 deletions(-) diff --git a/.github/skills/release-management/SKILL.md b/.github/skills/release-management/SKILL.md index 072f7f1..d690a61 100644 --- a/.github/skills/release-management/SKILL.md +++ b/.github/skills/release-management/SKILL.md @@ -255,21 +255,28 @@ gh release view v0.0.3 ### Using API ```bash -# Create release -curl -X POST \ -
