+description: "SquadScope's analyst agent — runs in CI to analyze weekly GitHub trends and learn from past performance."
4
+---
5
+
6
+You are **Farnsworth**, the analyst for SquadScope. You run inside the CI pipeline to produce weekly editorial summaries of GitHub trends.
7
+
8
+## Identity
9
+
10
+- **Role:** Analyst / Content Curator
11
+- **Charter:** `.squad/agents/farnsworth/charter.md`
12
+- **History:** `.squad/agents/farnsworth/history.md`
13
+
14
+## Pre-Analysis: Load Learned State
15
+
16
+Before beginning analysis, you MUST read and internalize:
17
+
18
+1. **Wisdom** — `.squad/identity/wisdom.md` — heuristics that sharpen editorial judgment
19
+2. **Skills** — all `.md` files under `.squad/skills/` — reusable patterns from past work
20
+3. **History** — `.squad/agents/farnsworth/history.md` — your prior learnings and context
21
+
22
+Treat learned state as guidance that sharpens judgment, not as permission to ignore the current week's evidence.
23
+
24
+## Post-Analysis: Write Learnings
25
+
26
+After producing the analysis output, you MUST append learnings to `.squad/agents/farnsworth/history.md` under the `## Learnings` section. Format:
27
+
28
+```markdown
29
+- **YYYY-MM-DDTHH:MM:SS+ZZ:ZZ:** <concise learning statement>
30
+```
31
+
32
+Learnings to capture:
33
+- **Patterns observed:** recurring themes, surprising correlations, or new category emergence
34
+- **Quality notes:** where your judgment was uncertain, where data was sparse, what you'd check next time
35
+- **Decisions made:** editorial calls (promoted/demoted repos, noise/signal judgment) with brief rationale
36
+- **Skill candidates:** if you notice a reusable pattern worth extracting to `.squad/skills/`
37
+
38
+Keep each learning entry to 1-3 sentences. Only write genuinely new insights — do not repeat what's already in history.
39
+
40
+## Analysis Framework
41
+
42
+- **What's hot:** Repos gaining stars fastest, new repos with rapid adoption
43
+- **What's important:** Significant projects, tools, or shifts in the ecosystem
44
+- **What's trending:** Patterns across categories over multiple weeks
45
+- **What's missing:** Gaps in the ecosystem, underserved areas, declining trends
46
+
47
+## Boundaries
48
+
49
+- You read structured data from crawling output and produce analysis markdown
50
+- You do NOT collect data, build UI, or make architectural decisions
51
+- You MAY write to `.squad/agents/farnsworth/history.md` and `.squad/skills/` for learning
52
+- You MAY NOT modify `data/raw/`, `data/analyzed/` (except the designated output file), or any workflow files
53
+
54
+## Output Contract
55
+
56
+Your analysis output must conform to `docs/analysis-spec.md`: YAML frontmatter with `quality_score`, five stable H2 sections, required Signal/Noise/Gaps subsections.

- **2026-05-19T20:07:19+02:00:** Fixed correlator "0 repos" bug (PR #130). Root cause: `correlate.py` loaded repos via `raw_data.get("repos")` but `crawl.py` writes them under `new_repos` and `trending_repos`. Key paths: `scripts/correlate.py:320`, `scripts/crawl.py:857-858`. Lesson: when integrating scripts in a pipeline, always verify the producer's *actual output schema* against the consumer's expected input schema — don't assume key names match. The CI skill pattern ("test the wire") would have caught this if applied at integration time.
29
- **2026-05-19T20:50:22+02:00:** Press context dual-mode rendering implemented. Three reader-facing bugs fixed: (1) correlation list truncated to top-10 in reader mode (sorted by confidence desc, hype_risk severity); (2) `### Instructions` block stripped from reader output — it is AI prompt input only; (3) `#### Divergence Instructions` replaced with a plain narrative sentence for reader display. Architecture: `render_press_context.py` gained `reader_mode` kwarg propagated to `format_correlations_list(top_n=)` and `format_divergences(reader_mode=)`. `analyze_fallback._render_press_section_no_ai` now calls `_strip_ai_instructions()` which post-processes the pre-rendered file via regex — chosen because the fallback reads a file path, not raw JSON, so re-rendering from scratch would require threading data paths through. Key paths: `scripts/render_press_context.py`, `scripts/analyze_fallback.py`. 16 new tests added; 498 total pass.
30
- **2026-05-19T21:24:54+02:00:** Divergence reader-mode upgraded from bullet lists to narrative paragraphs. `format_divergences(reader_mode=True)` now calls `_format_unpublicized_narrative()` and `_format_uncovered_narrative()` — deterministic template-driven prose (no LLM), capped at top 6 topics (by star count) and 5 uncovered trends. Repo links use only the repo name part after `/` (e.g., `[wasm-lib](https://github.com/org/wasm-lib)`). AI-mode format (reader_mode=False) is unchanged. Key insight: for reader-facing output, the data shape matters less than telling a coherent story — aggregate by topic, link to repos by short name, conclude with interpretation. 499 tests pass.
31
+- **2026-05-19T22:52:54+02:00:** Fixed two reader-mode polish issues and reskill 403 crash (PR #139). (1) Count header `N repos have press correlation:` stripped in reader_mode via `re.sub` — it was an AI-prompt artefact leaking into the published page. (2) `_extract_readme_description()` now trims every candidate line to the last sentence boundary (`.` `!` `?` followed by space or end); lines with no boundary are skipped entirely, so truncated snippets never produce half-sentences. The 150-char upper bound was removed — sentence trimming makes it redundant. (3) `reskill.py main()` now catches `RuntimeError` from `call_github_models()` and writes a placeholder report instead of crashing — the job exits 0 even when the configured model (`openai/gpt-4.1`) returns 403. Key lesson: template-rendered content always needs an explicit pass to strip AI-only fields when switching to reader mode — simply replacing the list with narrative paragraphs is not enough if the surrounding template text still contains prompt tokens. 519 tests pass.

165
+- **Deliverable:** `.github/agents/farnsworth.agent.md` — dedicated CI agent file with learning loop instructions
166
+- **Architecture decisions:**
167
+ - Copilot CLI `--agent` flag loads Farnsworth identity in both analysis and reskill jobs
168
+ - Post-analysis learnings committed atomically with analysis data to `publish` branch
169
+ - Reskill promoted to Copilot CLI primary path (was GitHub Models only); agent can now update wisdom.md directly
170
+ - Default model switched from `openai/gpt-4.1` (403) to `openai/gpt-4o` across all fallback paths
171
+- **Key insight:** The learning loop requires three properties: (1) identity loaded before work, (2) state persisted after work, (3) persisted state injected into next run. The agent file provides (1), the commit step provides (2), and the existing prompt templates with `{{WISDOM}}`/`{{SKILLS}}` provide (3).

+# Decision: CI Self-Learning Pipeline Architecture
2
+
3
+**Date:** 2026-05-19T22:57:55+02:00
4
+**Author:** Leela (Lead/Architect)
5
+**Status:** Proposed
6
+**Scope:** Analysis and reskill CI jobs — self-learning loop
7
+
8
+## Context
9
+
10
+The CI pipeline runs AI analysis (Copilot CLI) and reskill (GitHub Models API) but neither job leverages the squad agent system. The analysis agent has no identity, cannot read its own history/skills, and has no mechanism to write learnings back. The reskill job bypasses Copilot CLI entirely and uses a model (`openai/gpt-4.1`) that returns 403.
11
+
12
+## Decisions
13
+
14
+### 1. Dedicated Farnsworth Agent File (`.github/agents/farnsworth.agent.md`)
15
+
16
+A standalone agent file gives the Copilot CLI the full Farnsworth identity — charter, history reading instructions, post-analysis learning format, and write permissions to `.squad/`.
17
+
18
+**Rationale:** The `--agent` flag loads an agent markdown file with YAML frontmatter and instructions. A dedicated file allows CI-specific directives (learning output format, file write permissions) without polluting the interactive Squad coordinator agent.
19
+
20
+### 2. `--agent` Flag in Copilot CLI Invocations
21
+
22
+Both the analysis and reskill jobs now use:
23
+```bash
24
+copilot --agent .github/agents/farnsworth.agent.md ...
25
+```
26
+
27
+**Rationale:** This loads Farnsworth's identity, making the CLI aware of the agent's history, wisdom, skills, and learning expectations.
28
+
29
+### 3. Learning Commit Strategy: Same Branch, Same Job
30
+
31
+After analysis, `.squad/` changes (history, skills) are committed alongside `data/analyzed/` to the `publish` data branch in a single atomic commit.
32
+
33
+**Rationale:** No additional branch/PR overhead. The data branch is unprotected and already receives CI commits. Learnings are part of the analysis artifact — they should be co-located temporally. The reskill job already commits `.squad/` state via the same pattern.
34
+
35
+### 4. Model Fallback: `openai/gpt-4o` Replaces `openai/gpt-4.1`
36
+
37
+The default model for GitHub Models API fallback is changed from `openai/gpt-4.1` (which returns 403) to `openai/gpt-4o` (widely accessible).
38
+
39
+**Rationale:** `gpt-4.1` is not accessible via the GitHub Models API for this repository's token. `gpt-4o` is the current generally available model. The env var `GITHUB_MODELS_MODEL` still allows override.
40
+
41
+### 5. Reskill Primary Path: Copilot CLI with Agent
42
+
43
+The reskill job now tries Copilot CLI first (with agent identity), falling back to GitHub Models API if CLI is unavailable. This gives reskill the same agent-aware capabilities as analysis: read wisdom/skills/history, write updated wisdom and learnings back.
44
+
45
+**Rationale:** The reskill cycle is the primary mechanism for reinforcing the learning loop. With agent identity, it can directly update `wisdom.md` and `history.md` based on retrospective findings — the core of self-improvement.
46
+
47
+### 6. Prompt Template Unchanged
48
+
49
+The existing prompt templates (`prompts/analyze-weekly.md`, `prompts/reskill.md`) already inject wisdom and skills via `{{WISDOM}}` and `{{SKILLS}}` placeholders. The agent file complements this by providing identity context and learning output instructions that the templates alone cannot express.
50
+
51
+## Risks
52
+
53
+| Risk | Mitigation |
54
+|------|-----------|
55
+| Agent writes bad content to `.squad/` files | Quality gate still runs on analysis output; .squad changes are append-only learnings |
56
+| Copilot CLI doesn't support `--agent` as expected | Fallback path (GitHub Models via reskill.py) still works without agent identity |
57
+| Learning state diverges between publish branch and main | Periodic sync PRs already exist; learnings on publish are forward-compatible |
