What it does
Resolving Ingestion Warnings is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Diagnoses and resolves PostHog ingestion warnings — problems recorded while ingesting events (dropped events, rejected person merges, oversized payloads, invalid data). Use when a user asks why events are missing, dropped, or undercounted, why identify/alias calls don't work or accounts stay duplicated, why person or group properties aren't updating or profiles look inflated, why recordings have gaps, heatmaps are empty, LLM token counts are missing, why cookieless events vanish, or whenever the ingestionwarning…
Its SKILL.md is about 7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including reference files (for example `references/fixing-ai-endpoint-rejections.md`, `references/fixing-cannot-merge-already-identified.md` and `references/fixing-capture-replay-rejections.md`).
It works with PostHog. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…
When your agent uses it
- A user asks why events are missing
- Why identify/alias calls dont work
- Accounts stay duplicated
- Group properties arent updating
Example prompts
- “Use the resolving-ingestion-warnings skill to diagnose and resolves PostHog ingestion warnings — problems recorded while ingesting events (dropped…”
- “/resolving-ingestion-warnings”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Find the warnings: call posthog:health-issues-summary for the overall shape, then posthog:health-issues-list (kind=ingestion_warning…
- Triage by severity — the health issue severity mirrors what happened to the data
- Route by type using the table below. Where a references/fixing-*.md file exists, read it — it has the full diagnosis and per-SDK fixes…
- Pull the offending events: health issues don't carry per-event samples, so use posthog:execute-sql against system.ingestion_warnings to…
- Verify any fix: the ingestion_warning health issue auto-resolves once the warning stops firing, so re-run posthog:health-issues-list (or…
What it can do on your machine
Read from SKILL.md and the folder at commit 812e5c6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Resolving Ingestion Warnings loads about 7k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 226 tokens; SKILL.md has 1,796 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,796 words (~7,043 tokens).
“Ingestion warnings record problems PostHog hit while ingesting a project's events. They are the first place to look when events are missing, counts are lower than expected, or identify/merge calls don't behave.”
