error-recovery

error-recovery is a skill for Claude Code, Codex from Azure-Samples/eShopLite. It costs 24 tokens per session (785 once invoked), scanned A, a copy of error-recovery, MIT.

A set of recovery rules for coding agents when tools, networks, builds, tests, or other operations fail. It recommends retrying temporary failures, switching to alternatives, and diagnosing structured errors before fixing them.

In plain words
What is it for?
Use it for backoff retries on timeouts and rate limits, fallback tools or methods, and diagnose-and-fix cycles for build, test, and lint failures.
Why use it?
It turns failures into planned next steps instead of stopping at an error message. This helps distinguish temporary outages from problems that need a targeted code or configuration change.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

error-recovery scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Error Recovery Patterns

Standard recovery patterns for all squad agents. When something fails, adapt — don't just report the failure.


1. Retry with Backoff

When: Transient failures — API timeouts, rate limits, network errors, temporary service unavailability.

Pattern:

  1. Wait briefly, then retry (start at 2s, double each attempt)
  2. Maximum 3 retries before escalating
  3. Log each attempt with the error received

Example: API call returns 429 Too Many Requests → wait 2s → retry → wait 4s → retry → wait 8s → retry → escalate if still failing.


2. Fallback Alternatives

When: Primary tool or approach fails and an alternative exists.

Pattern:

  1. Attempt primary approach
  2. On failure, identify alternative tool/method
  3. Try the alternative with the same intent
  4. Document which alternative was used and why

Example: Primary CLI tool fails → fall back to direct API call for the same operation.


3. Diagnose-and-Fix

When: Build failures, test failures, linting errors — structured errors with actionable output.

Pattern:

  1. Read the full error output carefully
  2. Identify the root cause from error messages
  3. Attempt a targeted fix
  4. Re-run to verify the fix
  5. Maximum 3 fix-retry cycles before escalating

Example: Build fails with a type error → check for missing import → add it → rebuild.


4. Escalate with Context

When: Recovery attempts have been exhausted, or the failure requires human judgment.

Pattern:

  1. Summarize what was attempted and what failed
  2. Include the exact error messages
  3. State what you believe the root cause is
  4. Suggest next steps or who might be able to help
  5. Hand off to the coordinator or the appropriate specialist

Example: After 3 failed build attempts → "Build fails on line 42 with null reference. Tried X, Y, Z. Likely a design issue in the Foo module. Recommend the code owner review."


5. Graceful Degradation

When: A non-critical step fails but the overall task can still deliver value.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
