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 | $0.00026 | $0.02487 |
| Opus 5.5 | $0.00010 | $0.00995 |
| Sonnet 5.5 | $0.00005 | $0.00497 |
| Haiku 4.5 | $0.00003 | $0.00249 |
Grade A, and why
project-retrospective 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 1mo 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 — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project retrospective writer
Create LESSONS.md files that capture institutional knowledge, especially failures. Think like a journalist writing about your own project, be specific, be honest, name the actual mistakes.
Frame the retrospective: blame-aware, not pure-blameless
The 2024–2026 consensus in incident-analysis writing (PagerDuty, J. Paul Reed, Lorin Hochstein) is that pure blamelessness is neurobiologically unrealistic, humans default to blame. Healthier framing: acknowledge the blame bias exists and counter it deliberately. Source: https://postmortems.pagerduty.com/culture/blameless/
Cognitive biases to counter explicitly:
- Fundamental attribution error, blaming individuals for failures the system permitted
- Confirmation bias, looking for evidence that confirms a pre-formed narrative
- Hindsight bias, judging past decisions by knowledge that wasn't available at the time
- Negativity bias, over-weighting what went wrong vs. what worked
The voice rule isn't "no blame", it's "name the system that permitted the human action, not just the action."
Drop the single-root-cause framing
Allspaw's canonical critique (still the dominant view in 2024–2026) calls Five Whys / single-root-cause analysis "seductively satisfying and compellingly simple, but false." It locks analysts into a linear causal chain that terminates in individual blame. Source: https://www.kitchensoap.com/2014/11/14/the-infinite-hows-or-the-dangers-of-the-five-whys/
Use "how" narratives instead, gathering on four prompts:
- Cues, what signals were available, who saw them when?
- Interpretation, how did people make sense of those signals?
- Goals, what were people trying to accomplish?
- Taking action, what did they do, and what did they expect to happen?
The retrospective's job is to surface contributing factors, not declare a root cause.
When to run a retrospective
Pre-define triggers before incidents happen, not after. Google SRE specifies criteria: user-visible downtime past a threshold, any data loss, on-call rollbacks, monitoring failures requiring manual discovery, stakeholder request. Source: https://sre.google/sre-book/postmortem-culture/
What ships with it
5 files 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.

project-retrospective is a skill published in the GitHub repository jamditis/claude-skills-journalism (433 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 2,487 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
