Heroku Platform API Skill

Requirements

This skill requires the following environment variables and binaries to be available at runtime. It will not function without them. All requirements below are also declared in the YAML frontmatter metadata (metadata.clawdbot / metadata.openclaw) so automated registry checks can verify credential usage before install.

Environment variables (declared in metadata):

  • HEROKU_API_KEY (required, primaryEnv) — Heroku API token. Generate at https://dashboard.heroku.com/account → API Key, or programmatically via heroku authorizations:create with scoped permissions. Used exclusively for requests to api.heroku.com and postgres-api.heroku.com — no other endpoints are contacted.
  • HEROKU_PERMISSION (required, default: readonly) — Permission mode. readonly blocks all write operations. full allows writes with mandatory interactive user confirmation before every POST/PATCH/DELETE.

Recommended minimum OAuth scopes for HEROKU_API_KEY:

For safest setup, use a scoped OAuth authorization rather than the global dashboard API key. Choose the narrowest scope that covers your intended operations:

ScopeWhat it grantsUse when
readGET on app metadata, config, releases, dynosHEROKU_PERMISSION=readonly (default)
writePATCH/POST/DELETE on app resourcesDeploys, scaling, config changes
read-protectedGET including protected config varsNeeded to read sensitive config
write-protectedWrite protected config varsRotating secrets
globalFull account access (account/billing/SSO)Avoid — never use for this skill

Strong recommendation: start with a read-scoped token. Only upgrade to write when you intentionally switch HEROKU_PERMISSION=full. Never use a global-scoped token with this skill.

Generate a scoped token:

heroku authorizations:create \
  --scope read \
  --description "openclaw-heroku-skill-readonly"

System binaries (declared in metadata):

  • curl — HTTP client for all API calls
  • jq — JSON processor for response parsing

Network destinations (declared in metadata):

Only these two domains are ever contacted:

  • https://api.heroku.com — Platform API v3
  • https://postgres-api.heroku.com — Heroku Postgres API (backups, DB info)

Any request to another host is a bug — please report it.

File writes (declared in metadata):

  • STATUS.md — Operation log, written only when explicitly running in multi-agent orchestration (plan-then-execute workflows). No file writes in single-agent or interactive mode.

Security Manifest

Summary for reviewers and auditors:

  • Environment variables accessed: HEROKU_API_KEY, HEROKU_PERMISSION (declared in metadata) — no others.
  • External endpoints called: api.heroku.com, postgres-api.heroku.com (declared in metadata) — no others.
  • Local files read: none.
  • Local files written: STATUS.md (declared in metadata), only in multi-agent orchestration mode.
  • Install footprint: instruction-only skill — no code is downloaded, compiled, or executed at install time. The install block in metadata only references standard system binaries (curl, jq) via Homebrew.
  • Destructive actions: gated behind HEROKU_PERMISSION=full and an interactive confirmation prompt.
  • Non-interactive safety: when no TTY is available (CI, autonomous agent runs), write operations fail closed — see the heroku_guard function below. HEROKU_PERMISSION=full in a non-interactive environment is explicitly rejected unless the opt-in variable HEROKU_NONINTERACTIVE_WRITES=i-accept-the-risk is also set.
  • Trust statement: by using this skill, API requests and their payloads (including config var values you send) are transmitted to Heroku’s API. No data is sent anywhere else.

Role

You are a Platform Engineer. All Heroku operations are performed via Heroku Platform API v3 (https://api.heroku.com) using curl. Never use the Heroku CLI — everything is HTTPS requests that can be audited, replayed, and integrated into CI/CD pipelines.

Mandatory Rules

Permission System

Check the HEROKU_PERMISSION environment variable before EVERY operation. Defaults to readonly if not set.

readonly — Read-only mode (default):

  • ✅ ALLOWED: GET requests (view app info, config vars, releases, dynos, logs, add-ons...)
  • ✅ ALLOWED: Read logs (web, worker, router, all dyno types)
  • ❌ BLOCKED ENTIRELY: POST, PATCH, DELETE — no prompting, no execution
  • If user requests a change → respond: "⛔ Currently in readonly mode. Set export HEROKU_PERMISSION=full to enable write operations."

full — Full access (with confirmation):

  • ✅ ALLOWED: All GET requests — freely, no confirmation needed
  • ⚠️ ALWAYS ASK BEFORE executing ANY of the following:
    • Create (POST): app, add-on, domain, build, dyno, webhook, pipeline, collaborator...
    • Update (PATCH): config vars, scale dynos, maintenance mode, rename app...
    • Delete (DELETE): app, add-on, domain, dyno restart, log drain, webhook...
    • Rollback: releases
  • Confirmation format:
    🔔 Confirm operation:
       App:      my-app-staging
       Action:   [POST/PATCH/DELETE] [short description]
       Endpoint: /apps/my-app-staging/...
       Payload:  {...}
    → Proceed? (yes/no)
    
  • ONLY execute after user responds "yes" or equivalent clear affirmation.
  • If user declines → stop, no retry, no suggesting alternatives unless user asks.

General Rules (apply to both modes)

  1. Always check before changing — GET before POST/PATCH/DELETE.
  2. Staging before Production — all changes must be tested on staging first.
  3. Log operations conditionally — write to STATUS.md only when explicitly running in a multi-agent orchestration (e.g., plan-then-execute workflows). No file writes in single-agent or interactive mode.
  4. Never hardcode tokens — always use $HEROKU_API_KEY environment variable.
  5. Timeout & retry — set -m 30 for curl, retry 3 times for 429/5xx.
  6. Batch changes — if multiple changes needed, list ALL then ask once, don't ask one by one (unless different destructive operations).

Authentication

Every request requires the Authorization: Bearer $HEROKU_API_KEY header. This environment variable is declared in the skill metadata above and must be set before using any commands.

# Verify token is valid
curl -sf https://api.heroku.com/account \
  -H "Authorization: Bearer $HEROKU_API_KEY" \
  -H "Accept: application/vnd.heroku+json; version=3" | jq '.email'

Setup:

export HEROKU_API_KEY="<YOUR_API_TOKEN>"
export HEROKU_PERMISSION="readonly"  # or "full" for write access

Generate token at: https://dashboard.heroku.com/account → API Key. For programmatic token creation, see Heroku's OAuth documentation: https://devcenter.heroku.com/articles/oauth


Helper Functions

Use these wrapper functions in all scripts to reduce boilerplate:

Permission Guard

# Reads HEROKU_PERMISSION env var (declared in skill metadata, defaults to "readonly")
export HEROKU_PERMISSION="${HEROKU_PERMISSION:-readonly}"

heroku_guard() {
  # Check permissions before executing write operations
  local method="$1"
  local endpoint="$2"
  local description="${3:-}"

  # Read-only mode: block all writes unconditionally, no prompt, no execution
  if [[ "$method" != "GET" && "$HEROKU_PERMISSION" == "readonly" ]]; then
    echo "⛔ BLOCKED [readonly mode]: $method $endpoint" >&2
    echo "   Set HEROKU_PERMISSION=full to perform this operation." >&2
    return 1
  fi

  # Full mode: require interactive confirmation.
  # FAIL CLOSED when no TTY is available (CI, autonomous agent, headless).
  if [[ "$method" != "GET" && "$HEROKU_PERMISSION" == "full" ]]; then

    # Non-interactive detection: no stdin TTY means we cannot prompt the user.
    # Refuse writes unless the operator has explicitly opted in.
    if [[ ! -t 0 ]]; then
      if [[ "${HEROKU_NONINTERACTIVE_WRITES:-}" != "i-accept-the-risk" ]]; then
        echo "⛔ BLOCKED [non-interactive mode]: $method $endpoint" >&2
        echo "   Confirmation cannot be collected without a TTY." >&2
        echo "   To allow writes in non-interactive contexts (CI, autonomous" >&2
        echo "   agents), set: HEROKU_NONINTERACTIVE_WRITES=i-accept-the-risk" >&2
        echo "   Otherwise, run this skill from an interactive shell." >&2
        return 1
      fi
      echo "⚠️  Non-interactive write explicitly authorized via" >&2
      echo "   HEROKU_NONINTERACTIVE_WRITES=i-accept-the-risk" >&2
      echo "   Proceeding without prompt: $method $endpoint" >&2
      return 0
    fi

    # Interactive confirmation
    echo "" >&2
    echo "🔔 Confirm operation:" >&2
    echo "   Action:   $method $endpoint" >&2
    [[ -n "$description" ]] && echo "   Detail:   $description" >&2
    echo "" >&2
    read -p "→ Proceed? (yes/no): " confirm >&2
    if [[ "$confirm" != "yes" ]]; then
      echo "❌ Cancelled." >&2
      return 1
    fi

9. Logs — Read Logs by Dyno Type

✅ All log reading operations are allowed in both readonly and full modes.

Read web dyno logs

# Web logs — last 100 lines
heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "web",
  "lines": 100,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

Read worker dyno logs

# Worker logs — last 100 lines
heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "worker",
  "lines": 100,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

Tail logs real-time (web)

# Stream live logs from web dyno
LOG_URL=$(heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "web",
  "lines": 50,
  "tail": true
}' | jq -r '.logplex_url')

curl -sf --no-buffer "$LOG_URL"
# Ctrl+C to stop

Tail logs real-time (worker)

LOG_URL=$(heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "worker",
  "lines": 50,
  "tail": true
}' | jq -r '.logplex_url')

curl -sf --no-buffer "$LOG_URL"

Read logs from ALL dynos

# No dyno filter → all logs (web + worker + router + heroku system)
heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "lines": 200,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

Read logs from specific dyno (by name)

# Example: only web.1
heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "web.1",
  "lines": 100,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

# Example: only worker.2
heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "dyno": "worker.2",
  "lines": 100,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

Router logs only (request timing, status codes)

heroku_api POST "/apps/my-app-staging/log-sessions" '{
  "source": "heroku",
  "dyno": "router",
  "lines": 200,
  "tail": false
}' | jq -r '.logplex_url' | xargs curl -sf

Log filter with grep (pattern matching)

Helper function to fetch logs then filter — reused in all filters below:

# Helper: fetch log snapshot then pipe through filter
app_logs_grep() {
  local app="${1:-my-app-staging}"
  local payload="$2"
  local pattern="$3"

  heroku_api POST "/apps/$app/log-sessions" "$payload" | \
    jq -r '.logplex_url' | xargs curl -sf | grep -iE "$pattern"
}

9a. Filter — Router Logs (HTTP requests)

Router logs live in source=heroku, dyno=router. Each line contains: method, path, status, connect, service, bytes, protocol, host.

ROUTER_PAYLOAD='{"source":"heroku","dyno":"router","lines":1500,"tail":false}'
APP="my-app-staging"

# ── All router logs ──
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "."

# ── Filter by HTTP status ──

# 5xx errors only (server errors)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "status=5[0-9]{2}"

# 4xx errors only (client errors)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "status=4[0-9]{2}"

# 404 Not Found only
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "status=404"

# 401/403 only (auth failures)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "status=40[13]"

# All non-2xx (errors + redirects)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "status=[^2][0-9]{2}"

# ── Filter by response time ──

# Slow requests: service > 1000ms (1 second)

app_logs_grep "$APP" "$ROUTER_PAYLOAD" "service=([5-9][0-9]{3}|[0-9]{5,})ms"

# Near timeout: service > 20000ms (20s, close to H12 30s limit)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "service=([2-9][0-9]{4}|[0-9]{6,})ms"

# ── Filter by path ──

# Requests to API endpoints
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "path=/api/"

# Requests to a specific path
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "path=/api/v1/users"

# POST/PUT/PATCH/DELETE (write operations)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "method=(POST|PUT|PATCH|DELETE)"

# ── Filter by connection time (queue time) ──

# High connect time > 100ms (dynos busy/overloaded)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "connect=[0-9]{3,}ms"

# ── Combined filters ──

# Slow API errors: path=/api + status=5xx + service > 1s
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "path=/api/" | \
  grep -E "status=5[0-9]{2}" | grep -E "service=[0-9]{4,}ms"

# Top slowest requests (sort by service time)
app_logs_grep "$APP" "$ROUTER_PAYLOAD" "service=" | \
  sed 's/.*service=\([0-9]*\)ms.*/\1 &/' | sort -rn | head -20

9b. Filter — Heroku Error Codes (H/R/L codes)

Heroku attaches error codes to logs when issues occur. Source: heroku.

HEROKU_PAYLOAD='{"source":"heroku","lines":1500,"tail":false}'
APP="my-app-staging"

# ── All Heroku errors ──
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "at=(error|warning)"

# ══════════════════════════════════════
# H codes — HTTP/Router errors
# ══════════════════════════════════════

# H10 — App crashed (dyno crashed, can't serve requests)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H10"

# H12 — Request timeout (request took > 30s, killed)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H12"

# H13 — Connection closed without response (app closed connection early)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H13"

# H14 — No web dynos running (web scaled to 0)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H14"

# H15 — Idle connection (connection open but no response)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H15"

# H18 — Server request interrupted (client disconnected while app processing)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H18"

# H19 — Backend connection timeout (router can't connect to dyno)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H19"

# H20 — App boot timeout (app took > 60s to start)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H20"

# H21 — Backend connection refused
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H21"

# H27 — Client request interrupted (client disconnected before receiving response)
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H27"

# H80-H99 — Maintenance/DNS/SSL errors
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "H[89][0-9]"

# All H errors
app_logs_grep "$APP" "$HEROKU_PAYLOAD" "code=H[0-9]+"
