Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00105 | $0.01450 |
| Opus 5 | $0.00053 | $0.00725 |
| Sonnet 5 | $0.00021 | $0.00290 |
| Haiku 4.5 | $0.00011 | $0.00145 |
Grade A, and why
store-signals 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Store Signals
Pull what the shipped app is actually telling you and convert it into the next backlog — then verify whether last cycle's bets paid off.
This is the missing arc that turns build → ship into a loop:
ship → MEASURE → DIAGNOSE → next PLAN → build → ship → measure again…The ledger (SIGNALS.md) is what makes it a loop and not a monthly report.
Where it fits (read the seams)
- Not
analytics-interpretation. That interprets a metric you hand it (is 14% D7 good?). This is the end-to-end operate loop: gather every signal → cluster → diagnose → write a metric-tagged backlog → close last cycle's hypotheses. It uses analytics-interpretation's benchmarks. - Read-only on ASC. Never responds to reviews, never mutates metadata/pricing. It surfaces, gates
on explicit OK, and routes the change to the right command (
next-version,bugfix,metadata). - Feeds planning. Output is a dated backlog appended to
ROADMAP.md+ rows inSIGNALS.md, consumed by/apple:next-version//apple:release.
Prerequisites
- A live (or TestFlight) app; resolve its
appIdfrom.planning/STATE.md, elselist_apps+ confirm. .planning/context:STATE.md,APP.md,POSITIONING.md(job-to-be-done + guardrails)..planning/SIGNALS.mdif present — the OPEN hypotheses from prior runs (each with a target metric, recorded baseline, and "check-after" date). See signals-ledger.md for the ledger + backlog formats.
Flow
- Load prior hypotheses. Read
SIGNALS.md→ the OPEN rows to verify in step 5. - Pull the signals (read-only), this period vs trailing:
- Reviews / ratings —
list_reviews(recent, lowest-star first; flag unanswered),get_reviewfor detail. - Analytics —
get_analytics_report: retention, funnel/conversion, acquisition, impression→download. No report configured yet →setup_analytics_reportsand note "retention/funnel lands next cycle." - Sales —
get_sales_report: proceeds/units vs trailing 7/30-day. - Stability / perf —
get_diagnostics(crash/hang signatures) +get_perf_metrics(launch, memory, energy). - Beta —
list_beta_feedback_crashesif in TestFlight. - Listing —
get_metadatato spot ASO conversion problems against current copy.
- Reviews / ratings —
- Normalize & cluster. Dedupe reviews into recurring themes (requests / complaints / praise) with frequency; attach magnitude (users / revenue / retention implicated). Weight by frequency × revenue impact, not by how loud one reviewer is.
- Diagnose, filter, prioritize. Map each cluster to the core metric it moves (rating · D7 · Pro
conversion · crash-free rate · ASO conversion · proceeds); score impact × confidence ÷ effort.
Strategy filter: cross-check
POSITIONING.md— on-strategy → backlog; off-strategy → list under "Declined (why)" (never silently drop, never silently build). Carry the app's guardrails forward. Small-N (new app): say so, lean on qualitative reviews, flag low confidence. - Close the prior loop. For each OPEN hypothesis whose change shipped and whose "check-after" date passed: compare the target metric now vs its baseline → WIN / REGRESSION / NEUTRAL. WIN → resolve; REGRESSION → open a revert/rethink task; NEUTRAL → keep watching or retire.
- Write the backlog. Append a dated, metric-tagged section to
ROADMAP.mdand updateSIGNALS.md(one row per hypothesis; formats in signals-ledger.md). Then output a ranked digest (top 3-5 "what's hurting most, why, the proposed move"), the loop-closure results, and a suggested next command (/apple:next-version,/apple:bugfixfor a hot crash,/apple:metadatafor an ASO fix).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

store-signals is a skill published in the GitHub repository rshankras/claude-code-apple-skills (719 stars, last pushed 1mo ago), licensed MIT. It adds 105 tokens to every session and 1,450 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
